Boy, is it a bad time to have mutant superpowers or what?! Professor Xavier created a safe haven for muties at his Westchester mansion where he trains young mutants to use their powers for the betterment of mankind. The first graduates of his school were; Cyclops, Iceman, Angel, Beast and Marvel Girl (who later became Phoenix who later became Dark Phoenix). They became... the "X-Men." Other additions were Wolverine, Colossus, Nightcrawler, Thunderbird (who was too much like Wolverine so they axed him.. but then brought him back) and Storm (pre mohawk).
