Protagonists
Rex
- Ascended Fanboy: He manifest a big desire to be a Driver before Pyra comes into his life. She's a practically a dream coming true for him.
- Back From the Dead: Pyra brings Rex back to life by giving him half of her life force after he is killed by Jin.
- Took a Level In Badass: He begins the game as a non-Driver that after acquiring his first Blade don't knows exactly how to use her power properly and often loses or have to run away from fighting. Xenoblade 2, aside of everything else, is a story about Rex becoming a better fighter.
Pyra
- Cleavage Window: Pyra's armour has one, though her breasts are covered with some kind of black material.
- Fingerless Gloves: Pyra also wears those.
- Meaningful Name: Pyra, of course, comes from pyro, fire in ancient greek, and she is able to manipulate flames.
- Ms. Fanservice: Pyra is very, uhm....endowed and her costume exposes her thighs, hips, part of her back and parts of her glutes as well. Though some optional Blades are more fanservicey, Pyra is definitively the canon character who delivers more fanservice.
- Playing with Fire: Her powers allows her to create and manipulate flames as she wishes, and Rex can also do that as long he wields her blade. She does affirm isn't exactly fire though.
- Redheaded Hero: Pyra, a redhead Living Weapon.
- Reports of My Death Were Greatly Exaggerated: The common tale told around Alrest is that she died after helping Addam five centuries ago.
- Truly Single Parent: She was created by Mythra and from Mythra alone.
Mythra
- Green-Eyed Monster: It's implied she feels envy from Rex seemingly liking more Pyra than her.
- Token Evil Teammate: The nearest the party have to one. She is very mean and treats Rex with contempt.
- Truly Single Parent: She created Pyra and from her body and mind alone.
- Tsundere: She likes Rex, but don't likes to tell it outright.
Nia
- Cat Girl: Nia has cat ears and cat claws.
- Jerkass With a Heart of Gold: Nia is a very unpleasant person to be around initially, but she has her moral limits that she's not willing to cross.
- Token Good Teammate: Nia is this to Torna early in the game, until finally Malos gets annoyed enough to not care any more about keeping her on his side. Though she's still kind of a jerk and a snob, she mellows it significantly.
Dromarch
- Flat Character: He isn't much more other than Nia's loyal blade.
Tora
- Badass Normal: He can't be a Driver, not in a normal sense. He is however very smart and once he manages to activate Poppi he can use her perfectly to drill his way through opposition. However, as the cutscene before his proper debut shows, he can create other gadgets to fight.
- Science Hero: He creates his own weapons. Poppi is the most notorious example.
- This Is a Drill: His weapon is a shield, but with a drill attached to it.
Poppi
- Badass Adorable: She was created to be exactly that by Tora's family: cute and strong.
- Creepy Good: She basically threatens Nia when the latter asks of what her body is made of, saying that she would kill someone who knew that secret.
- Older Than They Look: Played with. She is born in the beginning of the game, but her childish way of speaking is just because she was created by Nopons that talk like that already. She isn't actually immature as the player may immediately assume.
Vandham
- Genius Bruiser: He is a very experienced warrior. He defeats Rex not because his blade is specially powerful but because he thinks more strategically than Rex.
- Grey and Gray Morality: Vandham is a mercenary and reflects a lot about how opponents in a conflict may be Not So Different, and that even sometimes good guys get help from things considered "bad".
- The Big Guy: The most physically imposing Driver of the party.
- The Last of These Is Not Like the Others: Is the only natural Driver on the party that can't equip any other blades.
- Shipper on Deck: Believes Rex is helping Pyra because he is interested into her, but don't find that dishonourable at all.
- Stating the Simple Solution: Tells Rex he may invoke Screw This, I'm Outta Here and leave Pyra, since she is basically a conflict magnet. Rex is reluctant, what makes Vandham assume there is a deeper motivation for it.
Five
- Walking Spoiler: The fact this character joins the protagonists isn't show in any trailers or promotional material, and it happens around the middle of the game.
Five's Blade
- Walking Spoiler: The fact this character joins the protagonists isn't show in any trailers or promotional material, and it happens around the middle of the game.
Zeke
- BFS: Carries an abnormally large sword that don't helps him in any way once the fights with him actually start.
- Eyepatch of Power: That was his intention of using it, giving the impression he is a powerful guy, but it fails completely once Pandoria says out loud he couldn't afford a second contact lens.
Pandoria
- Shock and Awe: Her element is lightning.
Torna
The main antagonists of the game, that hired Rex and other scavengers through Bana to retrieve Pyra, the Aegis. Outside of that, they're known for killing Drivers to take their Core Crystals.
In general
- Big Bad Duumvirate: Jin and Malos lead Torna like that.
- Dead Guy, Junior: In a bizarre case of this, they're named after Torna, a country was destroyed centuries ago, apparently by the Aegis himself.
Malos
- Evil Counterpart: He wasn't created to be one, but grew into one to the Aegis with time.
- Foreshadowing: He is able to use abilities with "Monado" on their name in his second boss battle, hinting there is deeper connections between this game and the first one.
- Obviously Evil: Malos wears a dark-blue armor and has a scary humanoid monster as Blade.
Jin
- Absurdly Sharp Blade: It can cut through fire of a titan dragon.
- Flash Step: Can do that without controlling a blade despite apparently being a human with no abnormal abilities.
- Malevolent Masked Men: Uses a grey mask over the top of his face.
Supporting Characters
Brighid
- Absolute Cleavage: To the extent a human shape can allow, since her dress is completely open in the middle until the groin.
- Eyes Always Shut: She never opens her eyes.
- Sexy Backless Outfit: Her dress let her back completely exposed.
- Zettai Ryouiki: Class A, but the curious thing is that they're made of fire.
Morag
- Anti-Villain: The reason she wants Pyra is because she fears her Driver may end up using her to cause a disaster similar to what happended 500 years ago.
- Bifauxnen: She have a very masculine voice and her clothes cover body completely. Thankfully, other characters make pretty clear she's a Lady.
- Hero Antagonist: She is only doing her job and trying to take down fugitives.
- Not So Different: From Rex. The cutscene after she and Brighid lose Rex and company implies she had the same concern as the boy: that someone would use Pyra as a weapon. That realization makes her give up on pursuing them, feeling the blade is in good hands already.
