and joins with the thunder god Thor, having also been on leave from the team, and the two head to the facility. As Thor battles Graviton with Iron Man's help, the Panther frees the captive Avengers, but Graviton defeats them again until he is tricked into thinking a fellow scientist he cares for has committed suicide. Graviton then panics and causes the entire facility to collapse on him, forming a giant stone sphere that is dropped into a river by the Avengers. Graviton later reappears, although is suffering from amnesia and is flickering in and out of existence. Somehow guided to the female scientist he has feelings for, Graviton attempts to abduct her but is stopped by Fantastic Four member the Thing and the Inhuman Black Bolt. During the battle, Graviton describes himself as becoming a "living black hole" and morphs into a humanoid. Graviton is then attacked until he loses concentration, and then apparently implodes and is considered dead. Graviton is eventually able to reform his body, and decides to seek a bride. Elevating a Bloomingdale's store into the sky, he takes several women hostage until tricked by Thor. Thor then maroons a defeated Graviton in an alternate dimension. Graviton is able to return when an anomaly opens a portal to Earth.

Graviton then recruits the supervillains Halflife, Quantum, and Zzzax as allies, but they are once again defeated by the West Coast Avengers. Graviton then defeats Spider-Man, and after a skirmish with the Fantastic Four, is defeated in turn by a cosmic-powered Spider-Man. Graviton then attacks the Avengers again, but is defeated when they overload his powers, banishing him to yet another alternate dimension. He then sends out a distress signal, which is noticed by the villains Techno and Baron Zemo. Graviton is eventually freed and attacks the teams the Thunderbolts and Great Lakes Avengers, but is persuaded by Thunderbolt Moonstone to rethink his priorities. Desiring still more power, Graviton recruited a team of criminals and looted the city of San Francisco, until eventually defeated by
