Since he was mentioned in Yua's profile...http://vignette4.wikia.nocookie.net/kingdomhearts/images/b/b5/Terra_BBS.png/revision/latest/scale-to-width-down/445?cb=20140609040222
Bio: A Keyblade Wielder thought long lost after being possessed by Xehanort. His revival made possible by the destruction of both Ansem and Xemnas at Sora's hands prior, as well as Prince Yua's sages, he sets off to stop Gemini's schemes at Yua's request. What he didn't expect was having to fight a brainwashed Aqua. At first doing it out of obligation, he befriends Rose.
Everything he had in Birth By Sleep (counting Keyblade Transformations, which were intended to be in the game, but hardware limitations prevented it.)
Attraction Flow* (The KH3 Hype.)
* He doesn't start with these, learning them later down the line.
Attraction Flow is best used with Allies, and allies are required
for Limits.Attraction Flow and Limit Break Sim
*At the Silver Millennium, Jupiter, Hina and Terra are fighting a Darkside.*
(If you've ever ridden Space Mountain at Disneyland... Yeah. That's what they're doing.)
Terra stood on the frontmost car, preparing the Meteor Shower Shotlock. As the coaster moved and swerved out of the way of the Darkside's fist, Jupiter blasted the Heartless with Jupiter Thunder Crash, Hina unleashing her own attack on the giant Heartless. Terra kept himself turned towards the Heartless as he fired star-shaped projectiles rapidly from his Keyblade.
Jupiter, Hina, and Terra leap off as he turns it towards the Darkside, causing the coaster to crash into it. Jupiter lands fine, Terra catches Hina. As the Darkside prepares to strike, Hina and Terra unleash their Limit Break, Daybreak, starting with spinning attacks of Light and Darkness, followed by multiple barrages of Dark Firaga and whatever projectile attack Hina has, leading into the final attack, called Amaterasu Flare. (Basically, Shadow Flare from Final Fantasy VII.)
Oh, and I'll also take Queen Serenity.
