x_(mega_man)
The main protagonist of the Mega Man X (series) series. X also serves as a guide during the Mega Man Zero (series) series as Cyber Elf X (mega man) and appears as Biometal Model X (mega man) in the Mega Man ZX series.
He is the successor of the original Mega Man (character) and is Dr. Thomas Light's greatest creation. Throughout the X series, X is an Maverick Hunter who fights alongside his partners Zero and Axl (mega man) in order to maintain peace and stability in the world and protect humans and Reploids alike from Mavericks, though X would like nothing better than the opportunity to stop fighting. Because of his aversion to violence, X is initially ranked a B-Class Hunter, but he is eventually promoted to S-Class.
