Mega Man X, known in Japan as Rockman X (ロックマンＸ Rokkuman Ekkusu) or simply known as X for short, is the main character of the Mega Man X sub-series and an alternate incarnation of the classic Mega Man. He appears in Super Smash Flash as a playable character. Though initially meant to "return" in some way, he was replaced with the original Mega Man in Super Smash Flash 2.
