Zebediah Killgrave the "Purple Man" was relaxing on an island in Polynesia, he was captured by Doctor Doom, who imprisoned Killgrave within a gigantic psycho-prism he had constructed on Doom Island. Doom magnified the Purple Man's will-sapping power and manipulated it to make himself the master of Earth, also using the help of Sub-Mariner. Virtually every one on Earth was compelled by the Purple Man’s power to obey Doom, and he succeeded in capturing a number of crime fighting superheroes. The Sub-Mariner himself was also enslaved.
Due to his unusual physiology, the Avenger Wonder Man was unaffected, however, and was able to free Captain America from Doom's mental control, who in turn freed Hawkeye, Iron Man and the Wasp. Together they freed the other captured superheroes. Infuriated at having been enslaved by Doom, the Sub-Mariner smashed the psycho-prism, thereby both killing Kiligrave and freeing the world from Doom's control.
On Earth-7642, Dr. Doom was recreating his Psycho-Prism, but it was stolen by Decepticons. They constructed a mysterious dome in Latveria, with the Prism emitting radiation causing people to become more violent. The Psycho-Prism was eventually destroyed by Wolverine, but Doom collected its remnants.
