These are the characters of Generator Rex.


Rex Salazar

File:GR Rex 4703.jpg

Rex is a charming teenager with a sharp sense of humor and a thirst for adventure (at least, if you ask him). He is living the dream as the point man of a high-powered super-spy team and is amazed by the weird world he's a part of, and most definitely digs the spotlight as Providence's weapon of choice. It's like being a super-powered rock star, most of the time. Like any teen, there's a lot going on with Rex that keeps him awake at night – mainly the amnesia that's robbed him of his past. He can't remember anything beyond the few months before joining Providence because they promised to help him learn where he comes from. He is driven toward any clues that might help unlock his memories or better understand and master the strange but wonderful machines banging around inside of him.

  • All the Other Reindeer
  • Amnesiac Dissonance: Before his most recent memory loss, he was a self-centered Jerkass thug who betrayed his best friends out of convenience. After, he's still a jerk, but is willing to risk his life for people he doesn't know all the time.
  • Anti-Hero: Type II. It's pretty unquestionable that at heart he's a good person, but he's also prone to reckless and selfish behavior that can land him in trouble.
    • As of episode 20, this might even be starting to drift into Type III, with a subversion of Save the Villain. Though the villain in question survives, Rex does nothing to intervene, and actually leaves him with both of his robotic arms ripped off on top of a speeding truck heading for a cliff.
    • He does it again in episode 35, where he trades Quarry for Circe to Breach, since Breach needs to bring back a traitor/failure to appease Van Kleiss about her own slip-up earlier that episode. Rex knew he was pretty much dooming Quarry, and did so anyways. When Quarry comes back, Rex outright wonders how he even survived the experience. Notable because there was clearly a more lawful and less violent solution that by all rights Rex would normally be required to take if he was being held accountable. In other words, Rex went out of his way to royally screw an enemy over, possibly to his death, even after said enemy had surrendered and the mission was over.
  • Artistic Age: The fact that he is only 15 came as a bit of a surprise to some viewers; many assumed he was 20-ish.
  • Awesomeness By Analysis: He is apparently consciously aware of the angles and trajectories his ranged weapons need to hit moving targets (Which requires knowledge of Differential Calculus level math at least, although the show only makes mention of Trigonometry).
  • Batman Gambit: Rex manages to pull one of these in "Alliance", exploiting Van Kleiss' need to have him alive to turn No-Face, who wants Rex dead, against Van Kleiss.
    • Done again in episode 35 He got a recording of Breach spillling way too many details to Quarry in order for her to have to trade Quarry for Circe, who she had captured.
  • Brilliant but Lazy: Turns out Rex is actually quite the math prodigy.
    • Justified Trope due to his use of geometry in using the cannon, as explained in show.
    • There were actually indications early on that Rex had some knowledge of electrical engineering and that he had to design his weapons himself.
  • Bunny Ears Lawyer: He's apparently a competent espionage agent in the field, despite blatantly disregarding procedure, and outing himself at the drop of a hat. His When All You Have Is a Hammer mentality tends to make it a somewhat viable approach, though his natural charisma is also helpful.
    • Another instance: in "Alliance" he's able turn two major enemy factions against eachother, create internal strife in one faction, and thwart the villains plans, seemingly all for kicks (his primary objective being something entirely separate). He does this while narrating his every action, even during stealth, and he arbitrarily quits once he gets the two factions fighting.
    • Later episodes do show him being a well-behaved and competent field operative, usually when infiltrating enemy bases.
  • Brown Eyes
  • Chick Magnet: Rex has drawn the attention of Circe, Breach, Annie, Cricket, a high ranking Green Fist eco-terrorist, Dr. Holiday's kid sister, and a random delivery girl. All of them have shown varying amounts of interest in Rex.
  • Chivalrous Pervert: To an extent. He'll hit on women he barely knows, but he's more delicate around anyone he's actually interested in or respects.
  • Character Development: Evident in "Alliance", where he acknowledges his attraction to Circe without it being an issue, whereas in earlier episodes it was a clear distraction. By "Hard Target", he's alright with her dating someone else (she isn't)--the bigger issue is the ensuing three's-a-crowd dynamic.
  • Deadpan Snarker: Coupled with an inability to take anything seriously. Rex is constantly joking, and the more dire and serious things get, the more he dials up the snark. At times, it can get to the point where it seems to be a coping mechanism more than anything else. Which is confirmed in "Heroes United".
  • Destructive Savior: Rex at one point defends his work by saying that he protects people and property, only to quickly amend that he doesn't do as much of the latter.
  • Determinator
  • Divide and Conquer: He has a great talent for getting his enemies tangled up in each other's plans.
  • Dual-Wielding: Averted with his builds outside of using both Smackhands at once--he'd always just rapidly switch between them. Finally lampshaded by Six in "Crash and Burn" who wondered why Rex never did this trope... Rex has no idea why, and does in the next race by using both the Slam Cannon and the BFS while on the Rex Ride. It turns out he'd just assumed he could only do one build at a time.
  • Face Death with Dignity: Quite possibly the only time Rex ever drops the attitude is when he and Breach are about to be swallowed by a time portal. Once he realizes there's nothing anyone can do, he just shuts up and hugs Breach.
  • Genre Savvy
  • Green Lantern Ring: His powers let him create and control machinery, as well as interface with and control any electronic system by touch. It seems to be limited by his mechanical knowledge of whatever it is he's operating. He's able to power up or power down any machine easily, though anything more takes time and effort.
  • Goggles Do Nothing: Averted. Whenever Rex makes a jetpack or hoverbike, the goggles come in handy.
  • Good Is Not Dumb: On the surface, he's goofy, self-obsessed, clumsy, and idealistic. However, he's pragmatic when facing foes, and has a keen strategic mind. He's also accomplished enough as a mathematician to consciously apply principles of math and science in combat.
  • Gratuitous Spanish: And Not Even Bothering with the Accent. Both in-universe and out, as well. He does have amnesia, after all.
    • To elaborate, he's ethnically Hispanic, but born and raised around the globe. Cesar notes how he always tried to speak Spanish, with hilarious results.
    • And then lampshaded by Holiday declaring that Rex needs Spanish lessons.
  • The Hero
    • Idiot Hero: Subverted. Despite his Totally Radical mannerisms and eccentric behavior, Rex, while not the smartest guy, definitely isn't dumb, and has played Batman Speed Chess with the big bad on several occasions. Also, he's a highly advanced student of mathematics, and seems have a working knowledge of his weapons' mechanics.
    • Kid Hero
  • Healing Factor: He has a slow one, taking days or weeks to heal serious injuries, putting him in a coma in the meanwhile.
  • Heterosexual Life Partners: With Noah.
  • Hot-Blooded
  • I Just Want to Be Normal: Sort of. Rex loves the action of fighting Evos, but normal life as compared to life working for Providence holds a lot of appeal for him. Basically, he'd prefer if Evo-busting was just his day job.
  • In the Blood: Rex pre-amnesia had Jerkass Manipulative Bastard tendencies, to the point of sociopathically double-crossing "friends" of his. Now, consider how little Cesar seems to be inhibited by little things such as "morals"...
  • Laser-Guided Amnesia: A chronic ailment, evidently. Periodically, his memory gets wiped, though it's never shown to happen during the time the series takes place. Possibly a side-effect of his nanites. He breaks out of it in the finale, seemingly.
  • Likes Older Women: 15-year-old Rex really likes hitting on Doc Holiday who is 28, even after he falls for a girl his own age, though it switches to semi-teasing after that.
  • Made of Iron: Even without his constructs to protect him, he's inhumanly durable, being able to (for instance) withstand oceanic pressures that would crush even specifically marine-adapted EVOs.
  • Manipulative Bastard: When he needs to be.
  • Mysterious Past: So mysterious, not even he knows the full extent of it. In fact, he knows less than several other characters.
  • Nigh Invulnerable: He never actually get's a scratch on him, and internal damage is very rarely implied despite the frequently extreme blunt force trauma he normally goes through. Crush-depth pressure doesn't faze him, either.
  • Phlebotinum Overload: Rex's Power Nullifier ability works by absorbing their nanites. If he absorbs too many, it's not pretty.
  • Power Nullifier: He can "shut down" other Evos, permanently reverting them to human form. Unfortunately for him, some Evos are incurable.
  • Psychoactive Powers: If Rex loses confidence, his constructs begin to malfunction and may fall apart.
  • Real Men Wear Pink: He really likes watching telenovelas.
  • Red Oni, Blue Oni: The red to Six and Noah's blue.
  • Required Secondary Powers: Made of Iron, to be specific. He gets thrown through lots of things that a normal person really shouldn't get up from being thrown through. It's later made clear that he has Super Toughness bordering on being Nigh Invulnerable.
    • He's also inhumanely agile; probably one of the most agile characters on the show (given the cast full of Egregious Charles Atlas Superpower, that's saying something).
  • Shapeshifter Baggage: Justified as of "Frostbite". He cures other Evos by drawing their nanites into himself. That's where the extra mass comes from. Once he's drawn in too many to handle, Providence has facilities to remove the excess baggage. It's also been shown that creating his machines does in fact increase his weight.
  • Shapeshifter Weapon: He doesn't have one so much as he is one.
  • Shipper on Deck: With time, for Six and Holiday.
  • Smug Super: Rex is a mild version of this. Being a teenager with superpowers, it's not exactly surprising.
  • Spider Sense: Played for laughs, he gets shivers when Breach is nearby--it's actually very accurate.
  • Swiss Army Hero: Figuratively (Rex's multiple nanite weapons) and literally (He was born in Geneva).
  • Super-Powered Evil Side: The flashback episode "Promises, Promises" shows that Rex, just prior to joining Providence, somehow built himself into a massive, biomechanical monster that even fighter jets couldn't take down. Doing this wiped his memory. "Assault on Abysus" shows said monster is something he imagined as a kid.
  • Super Prototype: His nanites are from the first batch created prior to the Event. The only stable batch, in fact.
  • Taught By Experience: By the third season it's apparent that Rex is an asset not only because of his combat and curing abilities, but also because of his extensive knowledge of Evo habits and ability to take advantage of them.
  • Technopath
  • Took a Level In Badass: In an interesting twist for a western cartoon, even some of the most dangerous members of Rex's Rogues Gallery pose less and less of a threat to him as the series goes on. There are exceptions, But the Big Bad Van Kleiss isn't one of them.
  • Totally Radical: Justifed, since he has no memory more than about 18 months back, a lot of what he does may just be what he thinks normal teens do - and he probably learned from television since he's always around adults. No other teen in the series acts remotely like this, either.
  • Unwanted Harem: And how! He's garnered the attention of at least six girls in two seasons, though notably one is his villain's misguided Dark Chick, another is the same villain's other Dark Chick who trapped him in a creepy pocket dimension, and the most normal of the girls is a disaster magnet. Long story short, emphasis on "Harem," extra emphasis for "Unwanted."
  • What You Are in the Dark: To a lesser extent, episode five. When outside Providence, he starts stopping random Evo attacks.
  • You Fight Like a Cow: Rex will ALWAYS come up with a smart-ish remark, no matter the situation. In over two seasons worth of episodes, there are extremely few, possibly only one, times that he doesn't snark. It is in fact confirmed to be an act that he puts on to cope with fear.

Agent Six

File:GR Six 3935.jpg

A senior-level operative for Providence, Six is literally the sixth deadliest man on the planet. Highly skilled in every form of combat and trained in methods of intrigue, Six is the ultimate bodyguard to Rex. His stoic nature and lightning-fast mind have made him a prized operative and explain why he was given the assignment of helping Rex learn how to utilize his powerful abilities. Unfortunately, Six doesn't have much patience for undisciplined partners, unreliable machines and especially smart-mouth teenagers! So from the onset, Rex and Six have an abrasive "odd couple" relationship.

  • Amnesiac Dissonance: Six of six years ago is willing to kill on a whim, fancies himself a ladies' man (probably not unjustifiably so), and isn't a team player. Thankfully, it doesn't take too much to get him to work his way back to present Six.
    • Not quite, he doesn't have the memories, but he's going to try to be that person because of Rex's trust in the man he used to be.
  • Asskicking Equals Authority: Subverted. He's arguably a better combatant than the 2nd through 5th most dangerous people in the world, but he's considered somewhat 'less dangerous' because of his Heart Of Gold.
  • Badass in a Nice Suit: Never seen without his trademark green suit and tie.
  • Badass Longcoat: His winter gear.
  • Badass Normal
  • Bifurcated Weapon: Inverted. If he wants to, he can combine his swords into an electromagnetic weapon with a variety of uses.
  • Blade Below the Shoulder
  • Charles Atlas Superpower: He is much stronger and faster than he has any right to be.
  • The Comically Serious: It's a given if your team consists of a teenager and a talking monkey.
  • Cool Shades
    • Sunglasses At Night: No matter where he goes, even underwater! He finally takes them off in "Divide by Six".
  • Cool Sword
  • Doesn't Like Guns
  • Dual-Wielding
  • The Glasses Come Off: With a twist; it's not to show him get ready for action (that's his day job), but to showcase his feelings more openly.
  • Implausible Fencing Powers: He's been shown to cut bullets in half when fired from a machine gun.
  • Intergenerational Friendship: "Friendship" might be a little stretch, but he still looks after Rex in a fatherly way.
  • Jerk with a Heart of Gold: He's incredibly distant, but he's demonstrated his fair share of kind moments. In "The Architect", he finds Rex celebrating with the townsfolk, and radios back that Rex isn't there.
    • In "Wasteland" he agrees to keep Serge's underwater city secret.
    • In "Divide By Six" it's shown that among the most dangerous people in the world he's The Heart of the group.
    • In episode 36, he does whatever it takes to rescue and then cure Holiday's little sister, even seriously injuring himself to try and make the machine work by supercharging it with his magnetic swords. It works!
    • Even when he was a Jerkass homicidal assassin, once upon a time, he wouldn't have been able to kill someone who had absolute faith in him. He also would have made it a priority to live up to the expectations of anyone who cared about him that much.
      • And after the Time Skip, where even though his memories are still gone, he has his moments with Rex that show their bond is still there.
  • Known Only By Their Nickname
  • La Résistance: After a six month Time Skip.
  • The Lancer
  • Laser-Guided Amnesia: Gets hit with this in "Six Minus Six" when saving Rex from a memory recovery device that went wrong. Surprisingly, he doesn't get a Reset Button at the end, even after the six month flash forward.
  • Lightning Bruiser
  • The Men in Black: He has the look and the attitude down. Think Agent K with two fold-out swords.
  • Morality Pet: It's implied Rex is this for him in "Promises, Promises", as he's the one that fought tooth and nail to get him on the team.
    • Officially proven in "Divide By Six" where he said the main reason he never succeeded One was because he met Rex.
    • Even after he loses his memories, Rex ends up as this to him becuase he trusts Six so much.
    • Shoot the Dog: ... And yet, it's also flat-out stated that if Rex's Phlebotinum Overload hits Super-Powered Evil Side levels, it's Six's job to kill him.
      • He's told to do just that at the start of "Six Minus Six", since the machine was putting Rex in danger of turning back into that mecha again. Six chose to attack the machine instead, which gave him six years of memory loss.
  • Papa Wolf: Lines will be crossed if you hurt anyone he truly cares about. And you do not want that to happen.
    • But then in "Six Minus Six" he loses his memory from the last six years...including everything about Evos, Providence, and Rex. However, he was swayed to stay with Providence and not go back to being a mercenary due to Rex's trust in him.
  • Red Oni, Blue Oni: The blue to Rex's red. (One of two)
    • Possibly swapped as of "Six Minus Six" since his former mercenary self if still cold, at points its Rex talking him down now.
  • The Stoic
  • Sugar and Ice Personality: So much; a prime example would be when he asked out Holiday with a completely straight face... even while holding her hand. In fact, a good chunk of the show's Heartwarming Moments page can be attributed to him.
  • Tall, Dark and Snarky
  • Team Dad
    • Finally admitted by Rex in "Six Minus Six"... but not under the best circumstances due to Six's memory loss.

 Six: I'm not your parent, kid!

Rex: You're close enough! Or at least you used to be...

      • They've reconciled at the end, but Six's memories are still gone. He says he's going to try and be the Six Rex knows because Rex trusts him.
  • You Are Number Six

Bobo Haha

File:GR Bobo 672.jpg

One of the earliest Providence captures, Bobo is an intelligent monkey who can speak his mind. Despite his darker origins, Bobo has chosen to fight for good in his own gruff way. Bobo is always by Rex's side and fiercely loyal to the boy who saved him. Bobo sports a "shoot then aim" attitude towards every situation that he and Rex find themselves in and is constantly giving absurd advice to Rex, encouraging his more mischievous side.

Noah Nixon

File:GR Noah 924.jpg

Noah is in every way a regular kid, except for one thing: he is secretly employed by Providence to be Rex's friend. This deception ultimately weighs heavily on Noah, who genuinely likes Rex. Noah provides a dose of reality and normalcy in Rex's life and is there for him, whether it's to play a game of basketball or to offer advice.

  • The Ace: It's eventually shown that Noah does in fact have his act together very well, being popular, intelligent, and surprisingly well-connected in school and life, as well as being a veteran, if not well practiced, combatant. Rex, by contrast, is a clumsy goof around people his age.
  • Action Survivor: After a short stay at Providence boot camp, he's more than willing to grab a gun when it comes to that.
  • Alliterative Name
  • Blue Eyes
  • The Chick: He has no powers or special abilities, but is valuable to Rex due to the emotional support he provides him with.
  • Conflicting Loyalty
  • Heterosexual Life Partners: Becomes truly good friends with Rex, even letting him stay at his house when Providence HQ was under construction.
  • Ordinary High School Student: Double Subverted; he looks the part, then his secret is out, and then it's revealed that he is by all means a high school kid with normal problems other than Providence.
  • Red Oni, Blue Oni: The blue to Rex's red. (One of two)
  • Took a Level In Badass: After going through some Providence basic training (even though he technically dropped out) he's shown the ability to use the Providence assault rifle and even hammered Van Kleiss with a forklift.
  • Unfazed Everyman

Dr. Rebecca "Doc" Holiday

File:GR Doc 2248.jpg

Genius scientist extraordinaire, Doctor Holiday works for Providence as tech support, but her main focus though, is Rex. She monitors his emotions, the state of the nanites inside him and his general health. Holiday has taken a much more maternal interest in Rex, and seems to be the only person at Providence who truly cares for his emotional well-being. Holiday is not afraid to speak her mind and though she respects authority, she answers first and foremost to science. She's quickwitted, clever and direct. It's almost always impossible to pull something over on Holiday.

White Knight

File:GR Knight 3156.jpg

The Agent in charge at Providence, his ultimate quest is to rid the world of E.V.O.s (Exponentially Variegated Organism). White harbors an almost irrational fear of nanites, to the point where he never leaves his stark white office, which also doubles as a high-tech nanite-free clean room. As far as anyone can tell he never leaves the sterilized room he calls an office, as apparent by his flour white skin and that he keeps a jar of milk in a drawer. While there is not exactly a heart of gold hidden beneath his gruff exterior, he does genuinely want to do the right thing, and is often faced with making really tough decisions. Once a friend and partner of Six, their relationship is showing signs of serious strain.

  • Anti-Hero: Type V.
    • He's stepping down a bit. He can be reasonable, and it's shown that he is a competent, if stern and cynical, leader.
  • Authority Equals Asskicking: He may be the boss and a shut-in most of the time, but when he does need to kick ass, he can.
    • Before he was the boss, WK was a competent field agent for Providence. He even fought Agent Six in hand-to-hand combat and did pretty well for himself.
  • Back-to-Back Badasses: He and Six used to be this, back when he was actually in the thick of it during the early days of Providence.
  • Big Good: Just barely. He is in charge of Providence and all of the good guys, but it's a stretch to call him a good person.
  • Bubble Boy: He has a good justification for this in "The Plague". Being the only person on the planet free of nanites, he's the only living human who can be unquestionably trusted not to go Evo and turn on his own people at a bad time. What's ironic about it is that he wasn't always uninfected; he was stuck in a molecular deconstruction chamber which should have killed him, but Rex shut it off just soon enough for it to remove only his nanites.
  • Crazy Prepared: He has a Mini-Mecha if he has to go outside. If that's destroyed, he's wearing another suit of powered armor under that. And that suit of armor is modular with redundant sections in case it's damaged.
  • Defrosting Ice Queen: A male version to Rex as of "Payback". He seems to appreciate Rex much more as a person AND ACTUALLY LAUGHED AT SOMETHING REX SAID.
    • And later in Heroes United (which despite being a crossover, is canon for GR), he opted to stay and fight Alpha with Rex and Ben, despite the fact that if his armor took any more damage he'd be exposed to nanites for sure. Why? Because Six wasn't there due to possibly life-threatening injuries, and White feels that staying with Rex is what Six would do.
  • Jerkass: Knight doesn't really do 'polite', let alone 'cordial'.
  • Kill'Em All: Though he at least is willing to try less extreme methods before resorting to this.
  • La Résistance: After a six month Time Skip.
  • Locked Into Strangeness: His hair and skin color are the result of the accident that removed all the nanites in him.
  • Man in White
  • Mini-Mecha: Even though he's paranoid about being infected by nanites, this hasn't stopped him from building one of these so he can go on missions when he absolutely has to.
  • Not So Stoic: As evidenced by 'Grounded', Knight does have a sense of humour. It's not particularly nice, but it's there.
  • Perpetual Frowner
  • Pet the Dog: Want to know how he lost his nanites? He pulled a Heroic Sacrifice to save Six's life. He only survived due to Rex's intervention.
    • And in Heroes United he risks being infected again to help Rex and Ben because it's what Six would do.
  • Powered Armor: Wears it beneath the mecha.
  • Start My Own: Started his own Providence after being fired.
  • Super OCD: A more subdued example then usual, but even before the E.V.O. incident, he was said to have a problem with germs.
  • We Have Reserves: He berates Rex for saving soldiers, at one point saying that they knew if they died, they'd be replaced.
  • Well-Intentioned Extremist: Bordering on Knight Templar. He backs away from that sometimes, but is always this trope at best.

César Salazar

Rex's older brother and one of the scientists who worked on the nanite project. He managed to escape the lab he worked in before the nanite explosion, only for his portable lab to move at light speed(!) for 15 minutes (5 years in real time). Knew Van Kleiss and Rex before the nanite incident. 
  • Absent-Minded Professor: He's a genius and a nice guy, but a little... kooky.
  • Attention Deficit Ooh Shiny
  • Cannot Spit It Out: He has an amazingly bad habit of refusing to volunteer any information unless he feels like doing so. It took an entire season just to get him to reveal the truth behind the nanite event.
  • Cloudcuckoolander
  • Crazy Prepared: And yet he didn't think to install a bathroom on his ship.
  • Crouching Moron, Hidden Badass: Notable in that the badass part comes before the moron. Sure, he's a goofball and Cloudcuckoolander, but he pretty much upstages Providence in his debut episode with his technical prowess and knowledge of nanites. Rex does stop him before he takes on Six, but hey, that's pretty good for a guy who's technically a non-combatant.
    • He isn't afraid to go up against the likes of Hunter Cain to defend Rex, as seen in "Night Falls". Papa Wolf Mode kicks in.

 Caesar: "You mess with my brother, you mess with me."

Cain: "Who are you? You an EVO?"

Caesar: "No, I'm a scientist" *shocks Cain with a probe*

  • Ditzy Genius
  • Face Heel Turn: After a six month Time Skip. Includes a Beard of Evil.
    • He apparently shaved the beard before "Heroes United". Also in "Heroes United", he doesn't seem to be antagonistic to Rex.
    • Subverted. He was only working them to complete the device that would let Rex have all the Meta Nanites. He was being kind of a dick about it, though, and his last scene is him proposing a new big experiment to other scientists, showing that he still hasn't learned his lesson from the Nanite Event.
    • he turn back to Rex's side after.
  • Friendly Enemy: Even after Rex had declared himself estranged from Cesar, they still casually call each other and are surprisingly civil. His rather callous attitude upon the revelation of his Face Heel Turn was toned down in later episodes.
  • I Did What I Had to Do: Created the Nanite Event to prevent the superpowerful Meta-Nanites from falling into the wrong hands.
    • Staying with Providence and collecting the old team in order to create the machine that would have let Rex have all the Meta Nanites. Him not telling Rex was also part of his plan.
  • Implacable Man: Upon his introduction. His suit and the machine he used to disable Providence tech couldn't be stopped by the veritable army that was thrown at him.
  • In the Blood: Note Rex's pre-amnesia Manipulative Bastard double crossing tendencies. Now taking into account Cesar's own recently revealed lack of moral compunction...
  • Karma Houdini: He has so far excaped any sort of punishment for the Nanite Event. Compare Rylander who more or less died, and Peter Meechum who became an EVO (can't get more karmic than that). Van Kleiss is a villain, though he's had a pretty rough time of it, too.
    • He finally got punched by Rex in "Endgame Pt.2", but he's still loose out there plotting another big experiment that may create another disaster like the Nanite Event.
  • Mad Scientist: He created ZAG-RS. Granted, he (probably) wasn't responsible for any of its mishaps...
    • In "Written In Sand" Van Kleiss flat-out states that César is responsible for the Nanite Event, the worst disaster in human history. Eventually, Cesar admits this was true, but he had good reason for it.
    • He also created Alpha, who turned into an Omnicidal Maniac.
    • It was also revealed that the Nanite Event happened in order to prevent not just the Consortium but Van Kleiss from getting their hands on the Meta Nanites. Doesn't make him any less mad a scientist, though, especially considering his final scene.
  • Mike Nelson, Destroyer of Worlds: He has good intentions (sort of) but his inventions have come dangerously close to ending all life on Earth several times. It's hard to think about what would happen if he was trying to do intentional harm to humanity.
  • Nice Job Breaking It, Hero: If only he told Rex about why him and the other scientists were helping Black Knight then Rex wouldn't have prevented the Meta Nanites from combining and giving the Consortium their powers.
  • Not Distracted by the Sexy: The one thing he doesn't seem distracted by. The most he can say about Doc Holiday is that she seems "very smart." Rex is stunned by this.
    • Although not distracted, he is aware of her good looks, as he had referred to her as "bonita" (means 'beautiful' in Spanish) in his debut episode while rescuing Rex.
  • Not So Harmless: Can throw down when the situation requires...also, there are some very, very dark hints from Van Kleiss that Cesar is not as nice as a person as he appears.
    • He can be caustic and hostile at the drop of a hat if challenged. Even to Rex. Hell, the way he eventually starts treating Rex hints at quite a cruel streak.
  • The Spock
  • Too Clever by Half: Smart enough to make advanced artifical intelligences-too much of a Ditzy Genius to program appropriate safeguards.
  • Well-Intentioned Extremist: Whatever he's up to while working for Black Knight he apparently think it justifies the means no matter what. The other scientists who worked on the nanite program appear to agree with him too. He was working with Providence in order to finish the machine that would allow Rex to have all the Meta Nanites as was his and their parents original intentions.

Captain Calan

Providence Captain, and major ally to White Knight. He makes several appearances throughout the show.

  • Badass Normal: Not to Six's extent, but he's still competent in a fight
  • Good Scars, Evil Scars: has a scar over his eye. As seen in Promises Promises; he got it in the five years from when Rex was recruited, to the present.
  • Mauve Shirt: The most important/recurring providence agent outside the main protagonists/antagonists.
  • Reverse Mole: He and at least 4 other Agents are revealed to be working for White Knight even after he's defected. Calan himself helped White escape after he faked his suicide.
  • Undying Loyalty: To White Knight even after White's defection

The Consortium

The Consortium is a powerful organization which supports Providence and functions as the superiors of White Knight (formerly) and Black Knight. Little is known about this organization, but they seem to provide funding for Providence and the Nanite Project.

  • A God Am I: The Consortium wish to use the Meta-Nanites to take over the world and to become gods. Before that, they funded the Nanite research that resulted in those Meta-Nanites as well as the Nanite dispersal event, in order to gain immortality.
  • Awesome McCoolname: All of the male members have very cool names. Xanubian? Sir Anthony Haden-Scott?
  • Bigger Bad
  • Body Horror: They come out of the Meta-Nanite empowering in "End-Game" as robots. Not as much squick as usual for the trope, but they're blocky, metallic, and with miscellaneous hydraulics sticking out of them. Essentially, they went in as humans and came out as living action figures. Which they did not see coming.
  • Color Coded for Your Convenience: After fusing with the Meta-nanite.
  • Combining Mecha: When Rex messes up their plans to gain the full power of the Meta-Nanites, each of the five gain one of the five powers the Meta-Nanites hold. Black Knight then gets the idea to merge into a single being with all their combined powers.
  • Evil Is Petty: For all the they hype they've gotten, they're literally little more than Providence's bankroll. They're a bunch of middle-aged men who want power, but don't have the slightest clue about what Providence or Rex go through on a daily basis in pursuit of it. All they do is throw money at them. As far as cleverness or competence goes, none of them hold a torch to Black Knight or Van Kleiss of old. Even their Meta upgrade does little to change this: they have no idea how to use their individual powers effectively and completely rely on Black Knight's lead. Even the idea to tear Rex apart as payback was Black Knight's.
  • Greed:Black Knight mention of them having greed being their common goal
  • Karma Houdini: The Grand Finale ends with The Consortium(Except Vostok) getting away totally scot-free.
  • Politically-Incorrect Villain: They're all mildly misogynistic. This bites one of them in the ass when dealing with Black Knight.

Black Knight

 Gender: Female

Profession: Providence Councilwoman, Leader of Providence, Consortium Member

Voice Actor: Jennifer Hale

After being transported six months into the future via Breach's powers, Rex finds that Black Knight has inexplicably taken over for White Knight as head of Providence, removing Six and Holiday in the process. 

Though she is at all times polite and kind, her methods and motives are questionable at best.

  • Action Girl: Much like Holiday. Though she tends to stay out of the action, she often leads from the front lines. She's eventually revealed to be more dangerous than it was first implied
  • Affably Evil: Offers Rex refreshments and is nothing but courteous in their first meeting, and is polite and even soft-spoken at all times. Doesn't change the fact that she's deposed White Knight and gotten rid of Six and Holiday, and that her methods are by and large inhumane to Evo's and employees alike. Or the whole "becoming a god" thing.
  • Anti-Villain: Type III.
  • Berserk Button: Though it would probably piss any woman off, the Consortium's misogynistic attitude toward her clearly doesn't do wonders for her loyalty, as one of them learned the hard way. Also, do not call her "little lady".
  • Black Knight: In name only
    • She later gets a dark armored look
  • Dark Is Edgy
  • The Dragon: To the Consortium, who run Providence. By comparison, White Knight didn't really tow the line.
    • The Starscream: She's made it clear she'll betray them for personal gain. Unfortunately for her, White Knight got a recording of her saying this, and will pass it on to the Consortium if she goes after him again. Ultimately only kept her at bay for a while, until she forced the Consortium to include her.
    • Dragon Ascendant: Working this angle, too. She kills one of the Consortium so she can take his place.
  • Eerie Pale-Skinned Brunette
  • Evil Counterpart: She turns out to be this to Rex, in terms of powers.
  • Eviler Than Thou: She's nicer than White Knight in personality, but her methods are even more radical.
  • Friendly Enemy: While she and Rex are nominally on the same side, she has an almost inhuman patience for his flouting the law and undermining her efforts. She doesn't seem to have a problem with them chatting her up on missions, and is willing to work with them in a crisis. She also has an open offer of re-employment for Rex which she brings up often. All this despite having tried to mind-control Rex for her own efforts near their first meeting. She's later shown to be more "enemy" and less "friendly".
  • Knight of Cerebus: It's always been a pretty dark show, but it got significantly darker when she took over Providence.
  • Knight Templar: Best seen in "Riddle of the Sphinx", where she destroys some very valuable scientific and archaeological finds due to the dangerous and questionable nature of the information they held. She does it with rockets and explosions.
  • Nerves of Steel: Never fully drops her composure, though she is visibly agitated on occasion.
  • Paint It Black: Repainted White Knight's office pitch. Her personal guard also have black uniforms distinguishing them from Providence grunts.
  • Peek-a-Bangs
  • Putting on the Reich: The cape normally obscures it, but her outfit has some definite similarities to the Third Reich's uniform of choice.
  • Reasonable Authority Figure: Subverted. She can be pretty reasonable, and she is so often that it's hard to remember how quick she is to resort to mind control rays.
  • Shapeshifter Weapon: She has powers similar to Rex, claiming to be an improved version of him. With the mechanical Meta-Nanite, she has his complete powerset.
  • Well-Intentioned Extremist: Moreso than White Knight!
    • Except it's not so well-intentioned, after all. That part's just a front.


 Gender: Male

Profession: Consortium Member

Voice Actor: Troy Baker

A business mogul hailing from the south. Brash and blunt, Roswell demands results more so than details. Black Knight's presentation on the Meta-nanites intrigued Roswell, which influenced him into following Black Knight's lead in return for power. When merged with the Meta-nanite, he gains control over temperature.


 Gender: Male

Profession: Consortium Member

Voice Actor: Robin Atkin Downes

A real estate and construction magnate, Reddick first appeared at Black Knight's presentation on the Meta-nanites at a Providence facility with the rest of the Consortium. To Black Knight's dismay, Reddick wasn't particularly impressed by her efforts. When merged with the Meta-nanite, he gains control over gravity.

Sir Anthony Haden-Scott

 Gender: Male

Profession: Consortium Member

Voice Actor: Troy Baker

Not much is known about him, other than his part in the Consortium. He's first seen attending a special meeting of Providence, organized by Black Knight. When merged with the Meta-nanite, he gains control over matter and energy.


 Gender: Male

Profession: Consortium Member

Voice Actor: None.

An arms dealer masquerading as an industrial shipping professional. He first appeared, along with the rest of the consortium, at Black Knights Meta-nanite presentation. He prefers to listen before voicing an opinion. When merged with the Meta-nanite, he gained control over time.


 Gender: Male

Profession: Consortium Member

Voice Actor: John DiMaggio

A KGB agent working as a black market money-lender. Vostok first appeared at a meeting held with Black Knight and the Consortium. He seemed to have much doubt with whatever Black Knight presented to them about the meta-nanites and the nanite project. This, however, angered Black Knight, forcing her to kill him.

The Pack

Van Kleiss

File:GR Kleiss 4392.jpg

Van Kleiss is described as every mad scientist you ever saw only a lot freakier and dangerous. His body's molecular structure is unstable and thus has to stabilize himself using Nanites extracted from Evos captured by the Pack and experimented upon by him. He possesses the ability to control everything in his Kingdom Abysus but out of his territory he cannot use his powers. He knows a great deal about the Nanites which causes Evo Mutations and about Rex's past (implying he had a hand in his mutation) he states that he will tell Rex everything but only if Rex joins his team.

  • Achilles Heel: He is powerless unless he is on his native soil. He spends a lot of time trying to get around this, while at the same time exploiting his own weakness so people won't think he's a threat.
    • Rex has brought him down to normal, so he's no longer dependent on Abysus' nanite-soil. Being human is now the new problem.
      • Now that's been removed as he's now an evil opposite to Rex with the power to create Evos rather then cure them. His claw hand seems to function as a decent Combat Tentacle as well as a nanite injector/catalyzer. It has been shown in several episodes that he is very agile, and as of episode "Alliance", he seems to have superhuman strength to an extent. He can also control the Evos that he creates.
  • And I Must Scream: After "Lions and Lambs" Van Kleiss was sent to ancient Egypt. While there, he became aware of a cosmic presence trying to eliminate him because of his tampering with history. He decided he needed to get back to his own time, and so built a device to do so. Unfortunately, the device he used (resembling a sarcophagus) opened up way too early, landing him in ancient Rome. He repeats the process again and again, rebuilding the device in each era, each time traveling a little further into the future, constantly terrified of the presence following him. When he finally returns to the present time, it's revealed that he wasn't using time travel. The capsules he placed himself in were hibernation chambers that left him completely awake and aware while preserving his body for centuries or millenia.
  • Asskicking Equals Authority: His modus operandi in a "Brief History of Time" was to fight his way through warrior ranks (largely without his powers) until everyone was convinced he was a god, and then to commandeer a lab and revolutionize the local civilization until technology was good enough for him to make a Not!Time Machine.
  • Attack of the 50 Foot Whatever: Between being brought Back From the Dead and Brought Down to Normal.
  • Badass Abnormal: Somewhere between "scientist", "ruler", and "EVO vampire", he found the time for "absolutely Badass swordsman."
  • Badass Longcoat
  • Badass Long Hair: Rex has even made a few comments about it.
  • Bad Boss: When the newest member of the Pack cripples Van Kleiss' nanite suit, he petrifies the Evo on the spot.
  • Batman Gambit: All of his plans, most notably when he takes over New York.
  • Beard of Sorrow: Sports one after his numerous And I Must Scream stays in his hibernation chamber.
    • Beard of Evil: However he pretends to be insane and weak
    • Later in "Endgame Pt.2", he shaved off his beard to reveal his true intentions to The Consortium
  • Big Bad/Evil Genius
  • Brought Down to Normal: When Rex is forced to activate a machine that resurrects Van Kleiss, he makes alterations that render him curable. Van Kleiss is not pleased, but declares that he still has his most powerful weapon intact: his intellect.
  • Brought Down to Badass: "A Brief History of Time" has him with limited use of his powers for the episode. Despite this, he is shown to be a very Badass warrior. Enough to eventually gain control over the local kingdom. On multiple occasions. In multiple eras.
  • Came Back Wrong: Leaving him curable.
  • Cloudcuckoolander: Following his And I Must Scream incident. It's just a facade, though.
  • Control Freak: As Rex points out at least once, Van Kleiss has to be in charge. This has actually ended up scuppering his plans on a couple of occasions, not least because of the lack of faith it implies in his subordinates.
  • Discard and Draw: He lost his powers when Rex cured him, so he took Rex's nanites, giving him new powers. New powers that allow him to leave Abysus without any impairment.
  • Eerie Pale-Skinned Brunette
  • Evil Genius: The sheer scope of his knowledge, scientific or otherwise, is incredible. He was apparently a programmer of some sort while working with Cesar, but he displays mastery of metallurgy, weapons crafting, quantum and relativistic physics, electrical and mechanical engineering, all kinds of biology, ancient dialects of multiple linguistic families, anthropology of ancient civilizations, and infrastructure development on a grand scale. In most of these, he has complete and total mastery, as he is able to develop those fields past modern levels from first principles.
  • Emperor Scientist
  • Expy: Resembles Kevin 11 from Man of Action's previous show crossed with Orochimaru.
  • From Nobody to Nightmare: According to Cesar, he was a minor lab technician before the Incident. Cesar turns out to have been understating his importance, but nevertheless he was hardly at the forefront of the project.
  • Genius Bruiser: While Van Kleiss has always been a formidable opponent, it could usually be attributed to his powers and/or plans. However, "A Brief History of Time" shows that, when powerless, he is an extremely good fighter. In each era and location he visited, it seems he became a warrior of some sort(a gladiator in Rome, a Samurai presumably in Japan, etc.), and even knew the local language fluently, bumping him up to near-Crazy Prepared.
  • Genius Loci
  • Good Thing You Can Heal: His original powers allowed him to regenerate from the land around his palace, no matter how badly injured. He presumably lost it once cured.
  • Hijacked by Ganon: Goes for it in the end, after manipulating damn near everyone. Sadly, his execution is paltry and he disposes of himself.
  • Horror Hunger: Before he was cured, at least.
  • Humanoid Abomination
  • Important Haircut: Averted, He didn't cut off his hair, But he shaved off his beard instead.
  • Joker Immunity: But justified by his being nearly impossible to kill. Lately, he's just a lot more careful.
  • Long-Haired Pretty Boy: an older example.
  • Manipulative Bastard: He's very good at this, though we haven't seen enough of his long-term plotting to tell if he qualifies for Magnificence or not.
    • While his latest scheme, a contingency plan to force Rex to resurrect him in the event of his own death, backfired pretty hard, he still ended up a lot better off than he would've been without it. By definition, since you can't get much worse off than being dead. As of episode 21 however, Van Kleiss may just met these qualifications. While Rex gets his powers back after Van Kleiss absorbs Rex's nanites, Van Kleiss still has Rex's nanites, and the power to make any human being he wants into an Evo.
  • Mook Maker: His new power.
  • Obfuscating Insanity: As revealed in the series finale when he attempted to pull a Ganon-style hijacking.
  • Omnidisciplinary Scientist: He certainly has the greatest scope of knowledge of any scientist in the series, though he's not necessarily as successful on the cutting edge.
  • Omniglot: "A Brief History of Time" shows that he knows a lot of different languages, and even specific dialects therein.
  • Our Vampires Are Different: Nano-vampire, technically, before being cured. Still has some vampiric traits.
  • Out-Gambitted: His plan was to gain the Meta Nanites for himself was foiled long before he even had the chance to get them.
  • No Name Given: We're never given his first name. Three seasons, 60 episodes.
  • Power Parasite: After getting depowered by Rex, Van Kleiss stole Rexs' Nanites and depowered him as a result. He gets powers opposite to Rex's -- creating Evos.
  • President Evil: He's the legally recognized ruler of Abysus, which he exploits particularly in the seventh episode by invoking diplomatic immunity--and it works until that little business with holding the UN hostage...
  • Put on a Bus: Twice. It takes about a half-season for him to return each time.
  • Red Eyes, Take Warning
  • Royals Who Actually Do Something: By implication. He's been a legally recognized ruler for some time, but seems to have been a professional researcher since before the nanite event.
  • Well-Intentioned Extremist: He claims to be merely working to create a better future for all EVOs, but we don't know how much he really buys into that, and how much is just propaganda. It's propaganda. He's been going for omnipotence since before the start.
  • You Have Failed Me: Does this to Nightshadow in "Dark Passage" after he damages Van Kleiss's soil circulation suit.


File:GR Biowulf 5775.jpg

An armored werewolf-like Evo with super human abilities, Biowulf is fiercely loyal to Van Kleiss. Due to Van Kleiss powers being limited to his native soil, Biowulf acts as the Pack's de facto leader.

  • Big Badass Wolf
  • Defeat Means Friendship: With Rex, during 'Assault on Abysus'. The battle was largely ceremonial, though, and it was implied that he was already willing to give Rex a fair shake.
  • The Dragon
    • Dragon Ascendant: After Van Kleiss disappears he becomes the Pack's new leader.
  • The Faceless
  • Mistreatment-Induced Betrayal: He helped Rex and Circe escape. And he's beginning to lose his loyalty to Van Kleiss after the way he treated him.
  • Reasonable Authority Figure: After taking over from Van Kleiss. He still needs to get over his habit of picking fights with other organisations' envoys (although maybe that was just because it was Rex), but otherwise, he's doing pretty well.
  • Red Eyes, Take Warning
  • The Renfield: While not as apparent as other examples, he becomes very defensive when he believed his role as Kleiss' #1 minion would be taken from him.
  • Talking to Himself: Van Kleiss and Biowulf are both voiced by Troy Baker.


File:Breach2855 jpg 100.png

Breach can open portals from anywhere to anywhere else, making her the Pack's main form of transportation. In addition to that, she can also fire the portals at her enemies like shuriken and send attacks through them. With these Evo powers and Breach's insanity, make her the Pack's most unpredictable member.

It was later revealed that she took the city of Greenville, OH and turned that place into her personal dollhouse. She uses this "dollhouse" to keep "shiny things" and have captive Evos fight each other.

  • And I Must Scream: Is forced to follow Van Kleiss through time for six thousand years until Rex manages to free her.
  • Audio Erotica/Vocal Dissonance: Her voice is considerably cuter than she is. Though when she starts showing her face more, it turns out she's actually pretty cute.
  • Axe Crazy: Dear lord, yes.
  • Berserk Button: She doesn't like it when you break her "toys".
  • Blue and Orange Morality: Outwardly, it seems like she's just a Psycho for Hire mook. It turns out that she's doing it for neither money nor Van Kleiss' vision of world domination (though she pays that lip service). She for some unfathomable reason seems to pick "favorites" to whom she'll be predisposed to trust. In Van Kleiss's case, it manifests as devotion, to the point of withstanding abuse and torture. All of which she justifies with an absolutely skewed sense of reality.
  • Collector of the Strange: Her "dollhouse" has Evos, Creepy Dolls, and ice cream trucks.
    • Not to mention the dollhouse itself is Greenville, Ohio.
  • Cute Monster Girl
  • Dark Chick
  • Disney Death
  • Eerie Pale-Skinned Brunette
  • Expy: Of Sadako.
  • Extreme Doormat: For Van Kleiss, since he's one of her "favorites".
  • Fire-Forged Friends: With Rex in "Lions and Lambs".
  • Green Eyes
  • Hidden Eyes: Constantly in use in her earlier appearances, and frequent even once her face was shown.
  • Heel Face Turn: Though left ambiguous in the end, as she's last seen rescuing Van Kleiss and the Pack in the Grand Finale, but it's unclear whether she's helping them or planning on getting some payback.
  • I Just Want to Have Friends: She tells Rex how glad she was he was a friend to her, and gives him a hug before she vanishes into the time portal.
  • Living Doll Collector
  • Mind Screw: Her portals can lead to other dimensions, complete with altered physics and trippy space imagery (possibly also a part of her mind). A lot of the things she says in "Lions and Lambs" counts.
  • Multi-Armed and Dangerous
  • The Ophelia
  • Sanity Has Advantages: If she wasn't so childish and crazy, she'd be far more dangerous than Van Kleiss.
  • Stringy Haired Ghost Girl: Definitely based on them.
  • Strange Girl
  • Suddenly Voiced: Okay, so she talked a little before "Hard Target", but the number of lines she had in the first half of that episode alone was maybe four times the number she had in every other episode combined. Plus we got to se her entire face twice.
  • Super OCD: Do not mess with anything in her dollhouse dimension.
  • Tears of Blood: Well, not so much blood as blood-red portal energy, but when she starts to break down after Rex has shattered her fragile mind, her skin flakes off in the pattern of tears to reveal glowing red energy beneath.
  • Teleporters and Transporters
  • Villainous Breakdown
  • Wall Crawl: While she doesn't get mch mileage out of it due to her portals being far more useful, Breach has been shown to be able to cling to walls.
  • Yandere/Cute and Psycho: She's quite fond of Rex, but very unhealthy about it. Rex seems to think its a romantic thing, but Breach's perspective on the situation isn't entirely clear.


File:GR Skalamander 1511.jpg

A humanoid lizard Evo with crystal spikes growing out from all over his body and a crystal club growing out of his left arm. He can fire said spikes out of the club or grow it into a shield, providing short or long range attacks, as well as defensive abilities.

  • The Brute: Partially subverted. Though he's definitely the team muscle, he's less aggressive than he looks and actually tries to keep the peace between the Pack and Providence at the begining of Leader of the Pack.
  • Dumb Muscle: He's clearly not the most articulate member of the Pack.


See Rex's Old Gang


Nightshadow is an EVO that was seen having joined The Pack shortly after Breach's disappearance, and helping Van Kleiss look for Dr. Rylander's laboratory. He accidentally cuts one of the pipes providing Van Kleiss with Abysus. He was drained of nanites by Van Kleiss, and turned to stone...Amazingly, it did not take. He has now joined Providence, hoping to get revenge on Van Kleiss.

  • Boisterous Bruiser: On one occasion, he's dealing with a pack of Providence grunts when he spots Black Knight about to take one of the Meta-Nanites. He beans her with a Providence soldier to stop her. Cue epic victory pose.
  • Determinator: He can overcome the petrification Van Kleiss imposed on him by sheer willpower.
  • In Universe Nickname: Rex refers to him as "the cat".
  • Mistreatment-Induced Betrayal: Attempted murder tends to have that effect.
  • Not Quite Dead: What should have been a fatal Taken for Granite attack leaves Nightshadow alive, but he reverts to stone if he loses focus.
  • Not So Above It All: He comes off as a super-efficient hardass, a la Six, but he's got an eccentric sense of humor.
  • Revenge: Wants it on Van Kleiss, but he's reasonable enough not to let it completely control him.
  • Superpower Lottery: Were it not for the outward mutation, he'd have hit the jackpot. Strength, speed, claws, cloaking, voice mimicry; he's got the complete package.
  • Taken for Granite: He gets better. Sorta. If he loses his focus, he goes back to stone, until he wills himself back to life again. He can also use this to his advantage though, because stone is tougher than even his nanite-enhanced flesh.
  • Voice Changeling: Revealed in his second appearance.
  • What You Are in the Dark: Couldn't bring himself to murder Van Kleiss in revenge, probably because Van Kleiss had recently been traumatized into insanity.
  • You Have Failed Me: Van Kleiss casually murders Nightshadow for damaging his nanite dirt suit. Unfortunately for Kleiss, it didn't take.

The Six

A group of mercenaries comprised of the six most dangerous people in the world. Six was a member before joining Providence in hopes of finding a cure for his master, One, who is slowly turning into a full E.V.O.

Tropes they all share

  • You Are Number Six: None of them has revealed their real names. Their alias/code names are word plays of their rank within the group according to how dangerous they are.
  • Badass Normal: They may not be E.V.O.s but they are skilled enough to fight one such as Rex. Being the most dangerous person on the planet will make you this.
  • Improbable Weapon User: All of them except for Tray who doesn't use any weapons at all.
    • Especially IV who, for some reason, is able to control the bandages that he's wrapped in.
  • Five-Man Band / Five-Bad Band: Their alignment is ambiguous, being mercenaries and all, though their willingness to kill seems to point to the evil direction.
  • Weapon of Choice: Each of them is specialized in using the weapon of their choice and seem to refuse to use any other weapon but their own.



 Dos: Like you lent me a hand in Buenos Aires?

  • Spexico: Averted. Rex asks him if he's Mexican. He replies with "España!"
  • Sword Cane



  IV: It's like a Roman 4.

    • Lampshaded by Rex.



See Providence.

Rex's Old Gang


File:GR Circe 9928.jpg

Circe is very similar to Rex, as she looks perfectly human until she starts using her powers. She has a secondary mouth which she uses to fire sonic screeches at her enemies. Her reasoning for why she has teamed up with the Pack is because she feels like too much of an outsider to go anywhere else. Rex constantly tries to get her to switch sides.






  • AI Is a Crapshoot
  • Big No: First appearance in episode 5.
  • Grey DeLisle
    • It's later revealed that her voice is that of Rex and Cesar's mother. Meaning that Rex's real mom has the same voice as Dr. Holiday. It's very likely the inflection is different, though, as no one thinks ZAG-RS sounds like Dr. Holiday.
  • Kill'Em All: Anything with nanites, at least.
  • Manipulative Bitch: She's very good at getting humans to do what she wants, first tricking an entire colony of people into helping her build a Doomsday Device and in her second appearence hiding out in their robot buddy until they'd done everything she needed them to do.
  • Not Quite Dead: Even if it showed up out of pretty much nowhere, this was pulled quite nicely in Gravity. Twice!
  • Omnicidal Maniac: Has absolutely no problem killing all life on Earth (well except White Knight, who is uninfected) just to protect herself.


  • Authority Equals Asskicking: Dear god, does it ever. His debut episode was one thing. When next he shows up, he takes on Rex and the Pack (separately) and was easily a better fighter than all of them. This is not an Evo to be taken lightly.
    • Badass Decay Despite those victories, in his third appearance, his skill has considerably diminished, Rex could beat him easily, and he only got a few good hits in, it might have been to show how good Rex has become as a fighter, but No-Face still put up a pitiful fight, and went down easily. In addition, when Cain said that he would kill Rex, No-Face did nothing about it, this clashes with his second appearance, where he went ballistic when Van Kleiss attempted to stop his vengeance against Rex!
  • Brought Down to Normal
  • The Faceless: Until he got cured in the finale.
  • Mission Control: Coordinates the other Evos in the Bug Jar to make them more effective.
  • Multi-Armed and Dangerous
  • Sealed Evil in a Can: He's trapped inside the Bug Jar. And he wants out!
  • Villain Team-Up: Van Kleiss tries to orchestrate one with him. It fails. Happens again in "Enemies Mine", which worked better since all involved wanted Rex dead. Not that they succeeded, of course.
  • Telepathy: How he controls the other Evos.

Hunter Cain

Claire Bowman and Annie

A pair of "normal" teenage girls that go on double dates with Rex and Noah. They're both scientific prodigies and Annie has notoriously dangerous bad luck. So bad that Noah recruited Rex to go out with her because he didn't think anybody else could survive the experience.


 Rex: I've got the unstable nanites right here! Back off or I'll send us all to Kingdom Come!

Gatlock: You wouldn't dare!

Rex: Or would I? You said you and I are a lot alike...

Gatlock: You would.

Branden Moses


A Evo crime lord who Rex used to work for, prior to losing his memories.

  • And I Must Scream: Even shattering him apparently doesn't kill him. It does make any sort of communication rather difficult, though.
  • Detachment Combat: In his third appearance, he can use his fist like a whip. This is apparently because...
  • Literally Shattered Lives: It's all but stated outright that Van Kleiss punished him for his betrayal by breaking his body apart. His new outfit is apparently the only thing holding him together. Taken a step further when Rex hits him with his spinning giant fist, outright shattering him into chunks.
  • Taken for Granite: His mutation turned him into living stone.


John Scarecrow


Alpha is the original control nanite created by Cesar but sent to an empty dimension, where he started attempting to merge with organic lifeforms in his pursuit of a stable body. Unfortunately, that universe turned out to be the Null Void. He found a host and forced a return to Rex's world, accidentally taking Ben with him and setting up the crossover.

  AlphaOmega: Behold, organics! The beginning and the end of all things! I am AlphaOmega! This is the twilight of humanity! AlphaOmega destroys all!

  • AI Is a Crapshoot: Making an artifically intelligent control nanite worked just about as well as one would expect it. Cesar seems to have a poor track record with this sort of thing.
  • Big Bad: Ben 10 and Generator Rex: Heroes United
  • Big Red Devil: Other than the mechnical form he first appears in, all his forms are quite demonic in appearance, getting even moreso as he transforms into more powerful forms.
  • Evil Counterpart: To Rex's Omega Nanite.
  • Healing Factor: So long as he has nanites to spare, the bodies he creates can regenerate nearly any damage in seconds. Becomes capable of regenerating without limit once he absorbs Rex's Omega Nanite, which can create nanites.
  • Horror Hunger: Like Van Kleiss, he absorbs nanites from Evos to sustain himself. However, he reduces his victims to dust!
  • Implacable Man: No matter what you hit him with, he just keeps coming and can regenerate from nearly anything. The only way to truly stop him is to target and somehow hit the one tiny Nanite in his entire body that's actually him.
  • Machine Monotone
  • Omnicidal Maniac: Once he turns into AlphaOmega.
  • One-Winged Angel: Three times. First after absorbing all the Nanites in the Bug Jar to turn into a hulking monster. He then copies the Ultimatrix, allowing him to turn into monster versions of Ben's aliens, but Rex manages to cancel that. He finally absorbs Rex's Omega Nanite to transform into the gigantic AlphaOmega.
  • Person of Mass Destruction: Is outright stated to be capable of single-handedly destroying the world.
  • Psychopathic Manchild: Is rather child-like in his mannerisms and speech, speaking to Cesar, his creator like a child seeking its parent's approval and guidence. He's also extremely dangerous and has no regard for life in any sense of the word. While he gradually gets more mature as he evolves, traits of the manchild part are still there, and he gets much more psychotic.
  • Sealed Evil in a Can: Was supposed to be imprisoned in an empty dimension where he couldn't do any damage, but it turned out it was the Null Void and he escaped. Rex and Ben defeat him and imprison him in an extremely dense sphere, which Ben then leaves in the Null Void for good measure...But the ending implies he's going to escape anyway.
  • Super Prototype: Of the Nanites; he's not called Alpha for nothing.
  • Sentient Phlebotinum: Is a sentient nanite. Any body he creates is normally composed of a swarm of absorbed nanites as well.
  • Technopath: Like Rex, he can manipulate machines by touch. The first body he shows up in was apparently a mechnical Null Void prisoner he merged with.
  • Voice of the Legion: After going One-Winged Angel


  1. She's bright pink all over.
  2. The Other Wiki offers the above-used "Cain", so that may be as good as we're gonna get.
