Re: superman with mjolnir and caps shield vs silver surfer and bannerless hulk
Most of the winning feats I've seen from Thor'a hammer, Mjolnir, involve battlefield removal, so the stipulation "no bfr" would seem to neutralize a lot of what that hammer brings to the table. Superman, in character, would likely refrain from using something as potentially lethal and destructive as the Ultimate Blast. Surfer and Hulk have no magic to negate; the cone barrier from Thor's second fight with Juggernaut would be a waste of time to create.
The only technique I can actually imagine useful would be a technique I've seen used exactly once, and that is the shrinkage of an opponent.
If he does that, Superman wins. Otherwise, I give scenario 1 to the team.
If scenario 2 is saying Superman can do everything he's allowed to do in scenario 1 PLUS he gets his speed advantage, I give him scenario 2. Bannerless Hulk, if I have the one in mind that YOU have in mind, would prove enough of a threat that Superman would resort to blitzing or using speed. He'd do that if only to effectively grant himself more time to find a solution, and with Mjolnir he WOULD eventually find said solution.
Regular Thor brawls entirely too much against Hulk.
Consistently.
If Superman is fighting Hulk like Thor normally fights Hulk AND still has the Surfer to face, Superman loses. Indeed, the likeliest resolution going by comic history, if Superman is fighting like Thor, would be Surfer effectively soloing both thoroughly engaged combatants by absorbing the gamma energy from Hulk, adding that to his own already formidable cosmic energy while weakening the Green Guy, and then blasting Superman into submission or simply talking him down.
Mjolnir counters more than magic. Mjolnir and Asgardian magic in general has always been able to counter or trump whatever the power cosmic can do. Superman clears....with the power of Thor.
