The X-Men fight against not just super-villains, but also spiritual evils like bigotry. The mutant most liable to suffer hate and fear is the blue-skinned Bavarian Kurt Wagner/Nightcrawler, who doesn’t pass for human the way most of his comrades do.
Nightcrawler’s first appearance in Len Wein and Dave Cockrum’s 1975 “Giant-Size X-Men” #1 saw Professor X rescue him from a pitchfork-and-torches mob. Yet, Nightcrawler is the kindest X-Man of all. As Kurt’s teammate Kitty Pryde has attested, Nightcrawler had “every excuse to become as much of a demon inside and out, but he decided he’d rather learn to laugh instead!”
Though excluded from the main cast of the 1992 “X-Men” cartoon (until revival “X-Men '97”), Nightcrawler made a memorable guest appearance in an eponymous episode. “Nightcrawler” directly centered on the defining irony of Nightcrawler: his Catholicism. He’s a man of God even though he looks like he was made in Satan’s image. His teleportation power even leaves behind smoke that smells of hellish brimstone!
I always thought Nightcrawler falling from faith would have been a great series. Murdering everyone in the blink of an eye he wanted, and being gone with near 0 trace he was ever there. Would have been an absolute madhouse of journey to find he did it, and to convict of anything.
(When people were saying D.C. was to dark, would have been the perfect time to launch it)
Maybe like an anti hero/non socially accepted stand plot. His own motives his own thought process, maybe even like the Jesuits vs the common Catholic belief system
