Mega Man X (video game)

Story
It is 21XX. Dr. Cain, a human scientest, has uncovered a robot from the past-Mega Man X. X can think for himself, and make his own choices. X's design interested Cain so much he started making similar robots, called Reploids. Not after long, Sigma, Dr. Cain's reploid general, betrays the Reploids and goes Maverick (the state of insanity for robots). Along with 8 other Mavericks, Sigma sets out on a Dr. Wily esque quest. Now, X and his friend Zero are the only ones who can stop him.
