Longshot is a superhero appearing in American comic books published by Marvel Comics, most commonly in association with the X-Men. Created by writer Ann Nocenti and artist Art Adams, he first appeared in Longshot #1, the first issue of a six-issue miniseries that represents the first major work of both Nocenti and Adams. The Longshot series established Longshot as an amnesiac fugitive from another dimension who discovers that he has a "good luck" power that protects him from harm when his motives are pure. He also discovers that he was a slave who led a rebellion on his dystopian world against his former master and enemy, Mojo.
