X is Mega Man's successor from the year 21XX and one of the four main antagonists of the finale trilogy. X is gay, and in love with Zero. They along with Bass and Protoman decided to kill Mega Man and Dr. Wily because they hated Season 2 and were bored. Throughout the trilogy the four chased Mega Man (And later Guts Man 2.0 as he helped Mega Man). X and Zero went to the sewers where Eggman and Wily tried to kill them but only killed themselves. Mega Man fought one final battle and killed X and Zero by Zero's hair.
