Xemnu was an intergalactic criminal who had been imprisoned on a prison planet, until he sneaked past guards and hijacked a supply ship. Xemnu arrived on Earth after his spacecraft ran out of fuel and crashed. His unconscious body is discovered by an electrician named Joe Harper. When he came to, Xemnu used telepathy to control Harper and later, each and every other human being on Earth and forced them to build a new spaceship so Xemnu could return home. As Xemnu departed, Harper was released from Xemnu's telepathic hold and sabotaged the ship's electrical system, electrocuting him and causing him to fall into a coma-like state. As the ship departed, Xemnu's hold over the people of Earth faded and they forgot he had ever existed.


Xemnu was created by Jack Kirby and first appeared in Journey Into Mystery issue 62. In his first appearances, he was called "The Hulk". This was before the green Hulk we know today was created. After that, his name was changed to Xemnu.
