Hisako Ichiki (aka Armor) has grown up to be become one of the most powerful mutants in the future. After a near-death encounter with Mr. Sinister that kept her enclosed in his own armour, Armor became afraid of enclosed spaces and considered retiring from his life as superhero. After several casualties in the X-Men, Armor regained the strength she needed and conversed his power, from defensive to offensive. Now using it only in one extremity, she has modified as such that her armor has become "reactive" and gives a jolt of energy to anyone who touches it, hence she has renamed herself "Reactive", to protect mutantkind and humankind alike in this new era.

A rather complicated custom, I originall considered trying to build a whole upper torso of armour, but time and technical difficulties prevented me from doing so. The most complicated part was the transparent arm.
