Nightcrawler is a member of a fictional sub-species of humanity known as mutants, who are born with superhuman abilities. Nightcrawler possesses superhuman agility, the ability to teleport, and adhesive hands and feet. His physical mutations include indigo-colored skin which allows him to become nearly invisible in shadows, two-toed feet and three-fingered hands, yellow eyes, pointed ears and a prehensile tail. In Nightcrawler's earlier comic book appearances he is depicted as being a happy-go-lucky practical joker and teaser, and a fan of swashbuckling fiction. Nightcrawler is a Catholic, and while this is not emphasized as much in his earlier comic book appearances, in later depictions Nightcrawler is more vocal about his faith.
Alan Cumming is embracing nostalgia as he celebrates his return as Nightcrawler in the highly anticipated 'Avengers... The actor posted a playful video of himself running and leaping, reminiscent of Nightcrawler’s unforgettable introduction in 'X2.
