He is a cosmic powered, robotic Hulk. Introduced in Eternals #14 (1977) by Jack Kirby, this living AI program was created by Galactus to help him find suitable planets for him to consume. The program would trick the inhabitant to build him a body. However, some inhabitants found a way to used the program against Galactus sending them to attack the World Devourer. Galactus abandoned the idea. The program eventually found it’s way to Earth, where it happened upon Dr. Gregson Gilbert who used the program to build Dragon Man. However, the program deemed this a failure and search for another person.

It eventually found the Mad Thinker, who built a robotic Hulk but instead of activating it, he put it in storage. It was eventually found by 2 college students who wanted to use it as a college mascot. However, a blast from the Eternal’s activated the program and went on a rampage. It was stopped when Zuras siphoned off his energy. It remained in the Eternal’s home until it was stolen by the Intelligencia, who reprogrammed it to obey them. They sent it to attack Red Hulk and A-bomb and it easily defeated them. He was then sent to attack Dr. Doom. Doom defeated and deactivated the machine. It was sent to a defunct SHIELD carrier and attacked the Red Hulk. Red Hulk defeated it and the machine was sent to SHIELD.

Cosmic Hulk is one of many character that very few people have heard about. However, he would receive a figure in the Marvel Select brand as a swappable head.
