they sAY that magik's weapon called soulsword can kill supernatural including demons, and nightcrawler was a demonic mutant. which means she can kill him?
Nightcrawler's dad is the shapeshifting mutant Azazel who, in the comic world, has been posing as a demon since forever. At some point he claims to be known by several of Satan's aliases. The implication is that Kurt's dad is the inspiration for the Satan myth. You can argue about whether or not being immortal and acting like a demon for centureies, in fact makes you a demon...
At any rate, Nightcrawler is not officially considered a demon, but I thingk Magik could still kill him. I could see Illyana being bonkers enough, but it would take some major changes for Amanda to try to kill him.
