Mojo is a Marvel Comics supervillain, an enemy of the X-Men, primarily Longshot. Created by writer Ann Nocenti and artist Art Adams, he first appeared in Longshot #3 (November 1985).
Mojo is one of the "Spineless Ones," an alien race that is immobile without advanced technology. He is a slaver who rules the "Mojoverse," a dimension where all beings are addicted to his gladiator-like television programs. The character is an absurdist parody of network executives.
Mojo was the main villain of the 1985/86 cult mini-series Longshot, the title character of which was one of his genetically engineered action stars. After Longshot joined the X-Men, Mojo has appeared semi-frequently as an X-Men villain.
