From Wikipedia
Nightcrawler is a superhero appearing in American comic books published by Marvel Comics, commonly in association with the X-Men. Created by artist Dave Cockrum, he debuted in the comic book Giant-Size X-Men #1. By the time of his creation, there was already another Marvel character with the same name, but with a hyphen (Night-Crawler), which was later changed to Dark-Crawler to avoid confusion.
