Godzilla (Earth-616)

I'm a huge Godzilla fan and would love to know more

Cain Marko, empowered by The Crimson Gem of Cyttorak. Possesses limitless physical strength and stamina, being classified as Thor-level threat capable of matching several forms of Hulk, including World War version. He's also largely unaffected by physical attacks and has ability to absorb and redirect energy attacks, in addition to being able to regenerate from skeleton, as well as having immunity to various contaminants. He's additionally able to increase his size up to 80 ft (25 m) in height.

Godzilla, prior to his experiments by Doctor Demonicus, assumed to stand at 600 ft (183 m) in height and weigh 250,000 metric tons. An extremely radioactive reptile armed with nuclear-fire breath, limitless strength and near-impenetrable hide, Godzilla was able to take on Fantastic Four and Avengers, retreating only because of Robert Takiguchi's convintions.
