This battle depends on who the writer is and whether it is a true fist fight meaning no magic use allowed.
If Pak is writing it then the 4 characters square off, run towards each other and Hulk trips over his own shoelaces. The other 3 stand and laugh at Hulk for a few minutes then go have a beer.
Best way for Zeus and Hulk to win is for Zeus to make Hulk angry before the fight. What is the best way to do this?
Zeus goes online and shows Hulk this forum...
Hulk then solos
