Axl

Axl is one playable character from the Mega Man X series. He has a very special ability called Copy Shot, which allows him to disguise himself as certain non-boss enemies. In Mega Man X: Command Mission, Axl's Hyper Mode allows him to turn into defeated bosses such as Wild Jango, Silver Horn, Mad Nautilus, Mach Jentra, Incentas, Depth Dragoon, Rafflesian and Ninetails.

In Mega Man ZX Advent, it is presumed that Axl makes an appearance as Model A. Even though it is revealed that Albert was the creator of Model A and states that the A stands for Albert, the Model is clearly modeled after Axl, both in color scheme and abilities (Guns, Copy ability, etc)
