Zero (Mega Man X3)

Zero is Mega Man X's best friend and partner. His creation is a mystery as well, yet many rumors and much speculation have arisen. Recently destroyed to protect X against the maverick Vile, Zero has been revived to continue the aid he has offered X in the past. Once part of the 17th Unit, Maverick Hunters, Zero now leads a Special #0 Class Unit. Always cool and calm, Zero takes quick action against the evil forces he hates so much.
