Abilities: Hulk, Bruce Banner's rage-fueled alter-ego, was created by Banner's version of the Super Soldier Serum and a huge blast of gamma radiation. His main power is his remarkable, untiring strength. Plus, Hulk is basically immortal, and Banner himself is a genius.

Power scale: 8. Hulk has traditionally been seen as the strongest Avenger physically — and for good reason, though he's been subdued by both Iron Man and Thor. Then he got wrecked in "Infinity War" and we haven't seen him fight since. Now that Bruce has managed to merge his mind with Hulk's body, he seems thoroughly disinterested in fighting. The Hulk body is still wildly strong and near-indestructible, but Bruce no longer has Hulk's ferocity, and now it looks like he only has one working arm.
