Nightcrawler has only three digits (including an opposable thumb) on each hand. He also has only 2 toes on each foot, each longer than an ordinary human's. Also a prehensile tail, pointed ears, fang-like canine teeth, no visible irises or pupils, and blue fur.
After Scott arrived with his team, they listened to a holographic message left by Professor X instructing them to carry out his last wish, to make sure Matthew Malloy was still under control. Thinking that Charles was being a hypocrite, caused friction between him and Iceman.

Nightcrawler was last seen in a memory of Cyclops' when Matthew telepathically probed his mind and caught a glimpse of all the members that Xavier has ever assembled as X-Men.
