Xemnu the Titan, also known as Xemnu the Hulk, is a fictional character in the Marvel Comics universe. Xemnu is an alien who has attempted to conquer the Earth several times.

Xemnu first appeared in the story "I Was a Slave of the Living Hulk!" in Journey into Mystery #62 (November 1960). He was created by Stan Lee and Jack Kirby.

Xemnu first appeared on Earth when his starship crash-landed on Earth after running out of fuel. When revived by the human Joe Harper, Xemnu reveals that he was a criminal who had been exiled into space for crimes against the rest of the universe, and had escaped a prison planet and fled to Earth. Xemnu then used telepathy to dominate Harper's mind and then the minds of every other human on Earth. He forced them to build him a new starship so that he could return home. As he departs, he releases Harper from his telepathic domination. Harper sabotages the ship's electrical systems, shocking Xemnu into a coma-like state. As the alien flew off, his mind control faded, and his former servants forgot that he had ever existed. Xemnu used telekinesis to direct an asteroid to strike his ship so that it would be knocked onto a course back to Earth. After crashing down on Earth a second time, the weakened Xemnu was taken into a circus sideshow. As he took control of the town where the circus was located, Joe Harper followed Xemnu's trail and confronts the alien. Xemnu attempts to disintegrate Harper, but Harper used a mirror to reflect the alien's psychic power back at it, and Xemnu's body was destroyed.

Xemnu then traveled through space in a non-corporeal form, and over the years learned that his home planet had been wiped out by a plague. He returned to Earth, possessing the body of an astronaut Richmond Wagner to gain a physical form. When the space shuttle arrived on Earth, Xemnu used his human host's popularity and his own telepathy to become the host of a children's television series. He used his mental power to place Earth's children under his thrall, planning to abduct them to repopulate his home world, only to be detected by Doctor Strange. Strange and his ally Namor the Sub-Mariner were defeated by the alien, but Xemnu was in turn beaten by the Hulk. Xemnu then took possession of Amos Moses, mayor of small-town Plucketville in an attempt to kidnap the townspeople of Plucketville to repopulate his home planet. The newly-formed Defenders (Doctor Strange, the Hulk, the Sub-Mariner and the Valkyrie) fought him, thus preventing him from using the townspeople to construct another starship. Xemnu continued his vendetta against the Hulk via a series of clones created from samples of other "classic Marvel" alien monsters, sent to attack the Hulk, and battled the Hulk himself; however, he was defeated when the dam burst. Xemnu later used Amos Moses' body in an attempt to once again take control of the Earth via television-transmitted hypnosis. Xemnu took mental control of the Los Angeles-based hero Wonder Man using him to attack his ally, the Thing. The heroes eventually defeated Xemnu, and he fled in a starship.

Xemnu The Titan has not been a contender in any CBUB matches.
