Ambitious young Hisako Ichiki enrolled at the Xavier Institute for its second public term. Hisako opposed the alien Ord when he infiltrated the Institute and threatened her and her close friend, fellow student Wing. Wing committed suicide after Ord injected him with a serum which "cured" him of his genetic mutation, taking away his ability of flight. Despondent, he committed suicide, and in the wake of this tragedy Hisako, her teacher Kitty Pryde, and several fellow students found themselves trapped in a sentient and hostile Danger Room with Wing’s seemingly reanimated corpse. Danger, as the intelligence named itself, battled the X-Men then left the Institute in search of Xavier himself. Hisako later aided Wolverine against both Ord and Danger before she, along with the X-Men and the villains, were all teleported aboard a S.W.O.R.D. craft bound for Ord's home planet, the Breakworld. Crash-landing on the planet alongside Wolverine, Hisako learned that he intended for her to become an X-Man, and took the codename Armor.
Powers & Abilities
Hisako's psionic armor acts as an extension of (although can be much larger than) her own body, which enhances her strength level and resistance to injury. While using her armor, Hisako has demonstrated the ability to hurl Wolverine and even assisted Colossus in restraining a small ship capable of breaking orbit from lifting off.
Her armor is generally impervious to most damage (as long as she can maintain it), but both lasers and Wolverine's claws have been shown to be able to pierce it, but he himself is unable too. Her armor is made from psionic energy, and has said it's her "ancestors", most probably meaning that's where the psionic energy comes from. Hisako can also release her force field into a concussive blast of energy, but it takes a lot of concentration
