9) World Breaker Hulk (with all implied strength and power)
10) Rulk and World Breaker Hulk
Stipulations:
Superman has read the bios of all Marvel characters and knows their powers and personalities in both rounds. The Marvel characters have read the bio for Superman and know his powers in both rounds.
CIS and Bloodlust are on for Marvel in both rounds.
Round 1 - CIS is on and bloodlust is off for Superman. He's in "boyscout" mode. Think AS Superman's personality.
Round 2 - CIS is off and bloodlust is on for Superman. Think of Superman with the rage Black Adam has in WW III.
Honestly, with nothing at stake such as innocent people getting hurt, in round 1 he might take the fall as early as 6 so that he doesn't hurt "good people making bad choices".
Round 2 however...Lord have mercy on their souls cause he sure as hell won't.
Round 2, World Breaker puts him down. It's hard to gauge how powerful he was because there was no way to gauge it. But we know that his low range efforts were planet-busting. He almost wrecked the Earth without trying. Not many people can stand against that.
1- 2: Comon guys, Abobination can hold is own against Hulk and A-Bomb can hold his own against Rulk. A gentle Superman would do good, then Rick and Sups would talk, smacking Abobination away, and then go fight another common ennemy.
2- 9: An all-out "I'm gonna tear your face out, you, piece of junk!" Superman would do probably pretty good and would probably go healing in the sun when needed. So He might pass Rulk, the walking PIS monster. But I think he stop at WB Hulk. It's my feeling that the gap of power are too far from each other, in Hulk's advantage.
I don't think Superman would choose NOT to hurt Hulk because he considers him a good person making a bad choice.... Superman wouldn't risk death so that he doesn't harm someone :/
