Wolverine claims "[Gambit] doesn't break a sweat against Apocalypse or Magneto." Actually, Gambit never even faced Magneto in the show - the only episodes where the X-Men face Magneto were Enter Magneto (1992) and Deadly Reunions (1993), and Gambit was absent from both of those episodes.
Debut: Nightcrawler/Kurt Wagner.
Adrian Hough, who provides the voice of Nightcrawler, also played Jean Grey's father in X-Men: The Last Stand (2006).
