Dazzler has to appear in "X-Men: Apocalypse." The disco queen turned X-Man debuted in 1980 as a roller-skate-wearing diva in a silver spandex jumpsuit, and her ability to convert sound into powerful light blasts made a big impact on readers at the time. She joined the X-Men in 1985 and has served with them off and on ever since. "Days of Future Past" missed its chance to adapt Dazzler in all of her disco glory, and with the franchise fast-approaching the '80s, it's the next-to-perfect place to get her on the big screen. A character like Dazzler could be used to satirize the pop music craze of any decade, but the thought of a Cyndi Lauper or Madonna-inspired Alison Blaire taking on the Four Horsemen of Apocalypse is just too awesome to ignore.
