Axl

Axl (アクセル) is one playable character from the Mega Man X series, and having an important role in two of the games he's appeared in so far. 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 Action Trigger, a special command introduced in the game, 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, a Biometal called Model A appears as the only usable Biometal in the game, possessing similar appearance, weapons and shapeshifting abilities. However, the game states that it is instead named "Model Albert", and the biometal seems to instead be an unofficial tribute to the character.
