Nightcrawler possesses superhuman agility, the ability to teleport, and adhesive hands and feet. His physical mutations include indigo-colored velvety fur 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.
- He is Kitty Pryde's boyfriend and lover.(in Lilo and Stitch's Adventures Series and Twilight Sparkle's Adventures Series)
