Also like Thor, Superman is shackled and brought to the despotic ruler of this planet, who compliments him on his combating spirit (“This one has the fire of a champion!” vs. “Well, he’s a fighter!”). Both heroes are then given an involuntary makeover and compelled to put on an area gladiator costume, besides Superman’s leaves rather a lot much less to the creativeness.
Next, Superman is informed to struggle the tyrant’s champion, a giant inexperienced man known as Draaga, whereas being watched by an enormous crowd of aliens in a large enviornment, however he refuses and gives him a pleasant hand … which Draaga simply makes use of to sucker punch him. Pretty quickly, Superman will get uninterested in being a punching bag and beats the crap out of his opponent.
So it is mainly the Hulk struggle from Ragnarok however with out the jokes. (Yes, the fundamental “Hulk as a space gladiator” concept and look are taken from Marvel’s Planet Hulk storyline, however that is about it.)
