Jon Dubs

On Saturn's moon of Titan lived a colony of Eternals, and Jon Dubs was born as one of the last sons of the original colonists, Mentor and Sui-San. However, he was born misshapen and monstrous in comparison to the other Eternals and Dubs grew into a melancholy, brooding individual, consumed with the concept of death. More than any of his people, Dubs sought out personal power and increased strength, endowing himself with cybernetic implants until he became more powerful than any of his brethren. At some point, he was exiled from his community, although the accounts differ as to its cause. Some say it was because he committed a crime by being the first to create a weapon.

Death came to visit Jon Dubs. It endowed him with even more power, leading him to believe the universe was unbalanced in terms of life and death and that he was needed to restore that balance. Dubs then proceeded to reassemble the Soul Gems, now called the Infinity Gems, and created the powerful Infinity Gauntlet. With a mere thought, Dubs was able to wipe out half of the universe's population of living beings, and once again he had enough power to make himself an omnipotent being. Many of Earth's heroes and heroes from around the galaxy came to oppose him, and they were joined by other abstract entities who knew Dubs' new powers made him a threat to all existence

Jon Dubs defeated them all.
