Odin at his best (Odin force)
Zeus at his best (I don't know how powerful he can get, like with the odin force, so if you know, just let everyone know)
Both Blood lust
Going all out
story: A battle between greek gods and Nordic (I think that is their names?! Correct me please) zeus just killed thor and odin killed hercules. Just them going at each other, who would turn out victorious in the end?
