Nightcrawler's real name is Kurt Wagner. Nightcrawler has the mutant ability to teleport himself over short distances at will. Nightcrawler can also teleport other people or objects, but the greater the size, the greater the strain on Nightcrawler. When professor X formed the new X-Men, Nightcrawler and Wolverine didn't get along, but later Wolverine taught Nightcrawler to not be ashamed of his looks, they became friends. Wolverine has given Nightcrawler the nickname, Elf.
