Note this page may contain details and tropes on characters who appear throughout the rest of the Unicron trilogy as well. Spoilers are uncovered at your own risk.


Optimus Prime

  Voiced by: Gary Chalk

  The Autobot commander of the forces on Earth, Prime leads the team through the Minicon Battles, against Unicron (twice) and finally in an effort to save Cybertron and reality from the Unicron Singularity.

Hot Shot:

  Resident team rookie, Hot Shot has learned a lot of hard leasons throughout his career, much to the chagrin of some of the older bots.

  • Big Brother Mentor: To Sideswipe, who actually starts refering to him as his brother. Possibly to the kids too.
  • Brent Miller: In Armada and Energon. After that...
  • Cool Car: He normally becomes a blue-and-yellow sports car, but in the second half of Cybertron, he is revived and upgraded so that he becomes a blue Humvee-like vehicle instead.
  • Crouching Moron, Hidden Badass: Despite his status as rookie, he is still very capable of kicking butt. He even gets to wield the Star Saber for a while in Armada.
  • Kid Appeal Character: He almost always sports yellow in his colour scheme, and interacts with young humans the most.
    • But in Cybertron, he's blue with yellow highlights. And in Energon the role is partially shifted to Ironhide, who disappears not too long after.
  • The Lancer
  • Lightning Bruiser: Though not quite as fast as Blurr.
  • Pride Before a Fall: ...and totally let the power that the Star Saber granted him go to his head. It ends painfully.
  • Shoulders of Doom: That "wHy mY sHoUlDeRs huRt" meme? Guess where it came from.
  • Young Gun: Probably not helped by the fact that his first foray into human culture consisted of spaghetti westerns.

Red Alert:

  Combat Medic of the Autobots, he may seem the Non-Action Guy, but harm his bots and you will regret it.


  Smokescreen originally intended to be one of the team members who accompanied Optimus Prime to Earth, but he entered the spacebridge portal late, and as a result, he materialized some time later then they did.

  • Badass: If being lethally wounded by the Requiem Blaster and still having the strength to try and take Megatron down doesn't count, what does?
  • Big Fun
  • Boisterous Bruiser
  • Demonization: The kids all assumed that he was a Decepticon when he first appeared. Of course the fact that he chased them all over the place and didn't intorduce himself properly probably didn't help much.
  • Intergenerational Friendship: Out of all the team, he and Hot Shot seem to be particularly good friends.
  • Nice Guy
  • Stout Strength


  Scavenger is an old war veteran. Who just so happens to be the Autobot who taught Optimus Prime everything he knows.


  Cool and aloof, Blurr is one of the later additions to the Autobot ranks. He initially thought of the mini-cons as mere tools, a thought which Hot Shot slowly shot down.


  The second-in-command of the Autobots on Cybertron, Jetfire departed Cybertron and arrived on Earth in order to help Optimus and the others.


  Hot Shot's newest partner, it didn't take long for Sideswipe to be captured by Hot Shot's friend-turned-foe, Wheeljack. Sideswipe was saved but the experince taught him a harsh lesson about war, and he quickly sobered up.



  Leader of the Decepticons. Megatron is a malicious, powerful leader. A refined, focused general who treats his men with little care, yet still infuses them with genuine respect for him and the Decepticon cause.


  Megatron's poorly-treated second in command. He loathed Megatron, because of the sheer mistreatment and contempt Megatron often pilled onto him, Megatron always seemed to expect to much from him.


  Demolisher is extremely strong and acts very serious at all times. He is wholly devoted Megatron and the Decepticon cause, unquestionably following orders at every turn.

  • Battle Butler: To Megatron.
  • Crouching Moron, Hidden Badass: Saves Megatron numerous times, but the first time he does in Energon, much tragedy ensues.
  • Hand Blast: His fingers are gun barrels.
  • AntivillanousSacrifice: In Energon.
  • Dumb Is Good: He's the closest thing to a "nice" Decepticon that you're going to find.
  • Only Sane Man: Compared to the rest of the Decepticons, he definitely feels this way.
  • Tank Goodness: In Armada. In Energon, he becomes a dump truck instead, but reverts back into a tank in Cybertron.
  • Undying Loyalty: Played mostly straight to Megatron, but the writers do subvert it at the end of Energon. When Galvatron hurls himself into the sun to stop Unicron and Starscream and Mirage follow, he and Snowcat don't bother to do the same.
  • Yes-Man


  Cyclonus has a very "trigger happy" personality, laughing and cackling as he fires his weapons almost completely at random on the battle field.


  Thrust is Megatrons' top Intelligence officer and master Tactician.

Tidal Wave:

  The lumbering giant Tidal Wave is the largest of the Decepticons, and proved himself a very powerful foe for the Autobots.


  Wheeljack, formerly an Autobot serving under Hot Shot. When Wheeljack was pinned beneath some debris during a fire, Hot Shot was forced to leave him to get help, but was prevented from returning to help. Wheeljack believed that Hot Shot had abandoned him, and when Megatron found and rescued him, he swore loyalty to the Decepticon commander.


Bradley "Rad" White

  Rad is the one who reactivated the Mini-Con ship while exploring some caves, and is inadverdently responsible for the restarting of the Autobot/Decepticon war.

Carlos Lopez

  Carlos is Rad's friend and was with him when he reactivated the Mini-Con's.

Alexis Rhodes/Thi Dang

  Alexis, along with Rad and Carlos befriended the Street Action Team Mini-Cons and Autobots on Earth. She frequently helped them by teaching them the ways of Earth.


  A primal force of evil, his origins lost to the mists of time. He is the embodiment of all darkness and hate that lurks in the hearts of all beings.

Voiced by: Mark Acheson, David Kaye (when Megatron is possessed in Energon)

  • Back From the Dead/ Death Is Cheap: This happens an incredibly frequent amount of times. You honestly wonder why the bots try to put him down again when he just gets back up.
    • The first is implied at the end of Armada, when his planet form is seen floating behind an unknown body. It's later confirmed at the start of Energon that he's just mentally inactive.
    • The second and third attempts happen during Energon. He manages to reactivate his body form and possess Megatron, then dies a few episodes later at the hands of Optimus Supreme. Then after that he possesses Megatron yet again, turning him into the incredibly large Galvatron in an attempt to recreate his body. This is thwarted when Galvatron hurls himself headfirst into a sun.
    • A fourth and seemingly definitive example from the Cybertron comic: Unicron frees himself from the Black Hole by hijacking a smaller Transformer's body, then recreates his body some time later. This time, he flees before Primus and the Autobots can defeat his weakened body.
  • Bigger Bad
  • Dangerously Genre Savvy: See Death Is Cheap's fourth example.
  • Eldritch Abomination: As is tradition, though this helped to codify this part of his character.
  • Evil Sounds Deep: Voiced by Mark Acheson in Armada (and a ridiculously small amount of Energon). Downplayed when he's voiced by David Kaye.
  • Omnicidal Maniac: This is the trilogy that established this trope best for him.
  • Planet Eater: Though unlike his debut appearance, he doesn't physically eat them, rather breaking the planet into smaller pieces and then devouring them. Energon shows this best.
  • Sci-Fi Writers Have No Sense of Scale: Not as bad as his first appearance due to the fact that he rarely engages any Cybertronians physically, but when Thrust is perched/standing on his shoulder you do run into some fairly notable issues, notably the fact that he should theoretically be a speck from the distance we see him.


  An intergalactic drifter, Sideways transforms into a motorcycle. His consciousness is apparently housed within the smaller robot head that rides his alternate mode, which can split into two components.
