Battles takes place on a barren planet that is seven times the mass of the Earth. The Planet has no population on it(besides the Hulk and Omni-Man) and the Gravity on the plane tis three times that of Earth.
Fight 1: Omni-Man vs Hulk(normal powers, morals, and personalities)
Fight 2: Omni-Man vs World War Hulk(normals powers, morals, and personalities)
The second fight is mainly because, while I know who Omni-Man is, I only just recently started reading Invincible. So Idk how powerful he is. So the second fight is for if Hulk isn't strong enough.
