In greek mythology he is one of the big three, aka the three strongest gods (not including the titans or primordial beings) in that mythology. Zeus, Hades, and Poseidon the three brothers.
Being king of the gods I'd agree him probably being a fairly good choice though knowing some of the stories say about Zeus he can be bit to much of a quick judgment and easy to anger so if that appears it could get pretty funny lol.

In terms of multiple mythologies mix together who knows how well he'd do. after all some of the others like Odin are more use to battle and have probably lived longer technically so more experience.
