He goes by the name Kurt Wagner. Nightcrawler also possesses superhuman agility, the ability to teleport, and adhesive hands and feet. He has indigo colored skin (which helps him hide in shadows), two-toed feet, and three-fingered hands. He also has yellow eyes, a prehensile tail (like a monkey), and pointy ears. His mother (in the comic books) is Mystique and his father was Azazel. He grew up in the circus.
Why do I like him? I've always thought the ability to teleport at will was just really fun. Because of that, Scorpion was my favorite Mortal Kombat character (he could also teleport around) followed closely by Raiden (who could also teleport). I even invented a secret order of assassins in my Dungeons & Dragons game who all get special powers (like mutants) and my favorite one can teleport.
So now that I've told you my favorite X-Men, do you have one? If so, name it in the comments please. You get bonus points if you tell me why you like them so much.
