The second iteration of the famed Blue Bomber needs no introduction for most people, but for the few who missed the memo, here's a quick summary: Created by Doctor Light. Became the basis for all Reploids. Became a Class S Maverick Hunter. Fights for everlasting peace. Oh, and he says he abhors fighting and killing, but just give him time. Considering the sanity of your average Godlike (Hi Kefka!), he'll be making HAL-9000 proud before you know it.

As expected of a hero as legendary as he, X's greatest power comes from his stalwart heart. This isn't just a cheesy metaphor either, as X's Heart allows the super robot to continue fighting even after his life energy is depleted, ensuring him a chance to access his second greatest power: the Ultimate Armor. Unlike most of his games, the Ultimate Armor he uses for the League is essentially a man-sized mecha packing enough firepower to level cities which he will unleash with wild abandon upon any duelist foolish enough to get in his way.
