I think you're a little confused - the characters' costumes were comic-based, just not necessarily the ones they were still wearing at the time. (Storm's was the random exception, which looked more like Ms Marvel's torso, presumably in order to include its "Power Glow chest". The line began with Wolverine, Storm, Archangel, Nightcrawler, Cyclops, Colossus, Juggernaut, Magneto and Apocalypse, two of whom weren't in "Pryde", and some (particularly Cyclops in his X-Factor gear) looked strikingly different from their animated counterparts.
