The Doomsday man was created by the United States after the first Moon Landing. It was designed by Doctor Krontron. He was created to explore other planets and to survive and protect where man could not. It's armor was made to withstand any temperature or gravity, enabling it to even function on the Sun. They soon realized that this robot was indestructible and could not unleash it upon the world.
The government build a massive concrete tomb on a remote island in the Pacific to house the robot. It obeyed it's orders to enter and once it did the tomb was sealed by remote control. Once sealed, the remote self-destructedso that no one could ever gain access ever again. The island was under constant guard under the US military.
Many years later, monitors detected tremors coming from inside and realized that the Doomsday Man was no longer immobile. The United Nations gathered to discuss the threat. The Silver Surfer
joined this meeting. Although the delegates could not agree, the Surfer knew he must do something. He took the creator and went to the island.
The Surfer traveled under the tomb and made his way inside where they found the Doomsday Man acting without any commands. It attacked the Surfer under it's own will. It then took a experimental cobalt bomb that had also been placed in the tomb so that it may never be used. Doomsday Man headed for the US mainland.
This was all a plot of Dr. Krontron's. He planned to allow this to happen so that he could become wealthy from saving the world from his own creation. The Silver Surfer created a chasm to the Earth's core and Doomsday Man fell in. But as he scrambled to pull himself up he killed his creator. He then plummeted to the center of the Earth.
Doomsday Man was recovered by AIM
- a group that was interested in the Cosmic Cube
. They attached him to an ICBM missile and launched it into space. Ms. Marvel
caught up with Doomsday Man in space, but he had fallen to the Earth. Doomsday Man attacked Ms. Marvel while she recovered memories of her past. She remembered schematics of Doomsday Man, in particular a weakness in the back of his skull. Ms. Marvel punched through the weakness and deactivated Doomsday Man. The robot punched Ms. Marvel just as she fainted, and Kerwin Korman
arrives at the scene. He attacks Ms. Marvel, enabling him to reach the Psyche-Magnitron
but as he touches it, it explodes. Ms. Marvel survives and crawls away from the destruction. Doomsday Man and Korman were thought to be vaporized or buried under the rubble.
