This makes him the proverbial 'father' of the Reploids.

Despite this, Cain was able to replicate X's general architecture, making X the precursor to each and every Reploid brought into production. Cain, the scientist who found him, was never able to fully analyze X's internal systems and system code. X is the first robot to possess sophisticated technology and behavioral adaptation, based on the last design of Dr. Because of his aversion to violence, X is initially ranked a B-Class Hunter, but he is eventually promoted to S-Class. Throughout the X series, X is a Maverick Hunter who fights alongside his partners Zero and Axl in order to maintain peace and stability in the world and protect humans and Reploids alike from Maverick Reploids, though X would like nothing better than the opportunity to stop fighting. He is the successor of the original Mega Man and is Dr.

X also serves as a guide during the Mega Man Zero series and appears as Model X in the Mega Man ZX series. Mega Man X, named Rockman X (ロックマンエックス Rokkuman Ekkusu) in Japan, commonly called "X", is the main protagonist of the Mega Man X series.
