Worldbreaker Hulk vs Odin
WBH and Odin are in a closed arena the size of a football field. There is no BFR. WBH thinks Odin just maliciously killed Betty and Skaar.
WBH gets TEN free double fisted punches on Odin, who has no weapons. Then WBH gets FIVE free thunderclaps. After all that Odin can fight back but only head to head (no energy drains, no time freezing, etc). It's a pure slugfest. (though he can amp his physical stats). Who wins?
Hulk is going to be hitting Odin as hard as he possibly can with his free hits.
