I would see Captain and Agent giving up their shields to She Hulk and Thing because they could use them with stronger affect. Spider-Man, Green Arrow, Batman, Robin could use long range weapons. Captain America Daredevil Electra could use pressure points. sounds like an idea
Somebody please list for me the powers Thor has without Mjolnir.
Because as far as I know, Mjolnir controls:
1) Thor's flight
2) Thor's ability to generate lightning
3) Thor's ability to control weather
4) Thor's ability to generate portals and teleport people
5) Thor's ability to magically heal
6) Thor's ability to detect and eliminate magic forcefields
7) Thor's ability to godblast
In which case we're left with a superstrong brick who is not in the habit of using any practical degreee of superspeed.
The Asgardian version of the Hulk, if you will, with the significant difference that Thor can apparently breathe in space, and, presumably underwater.
Someone correct me if I'm wrong and tell me what he CAN do, please.
Otherwise, taking Thor as tank, the solutions I see are:
Spider-man blinds with webbing. Often.
Captain America and Batman alternate as battle conditions dictate.
Each leads group, with the upfront goal of keeping Thor continually off-balance, and with the final goal of scoring knockout.
Most likely scenario for knockout:
Spider-Man blinds Thor quickly while She Hulk and Ben are in striking range. She-Hulk and Ben deliver their hardest blow, one from each side, at Thor's temples while he is blinded.
If necessary, precede this action with a web-bola of C4 striking Thor's face (Batman carries this explosive and a few others as a fairly standard part of his bat-belt equipment). Obviously, have someone assure that Thor will not be killed or permanently injured to both Spidey and Bats first. Explosion should either knock Thor out directly or leave him disoriented enough for Ben and Jen to finish the job.
Thor still possesses his weather powers w/o his hammer.
He just uses his hammer for fine control and amplification of his already existing powers.
Also a well written, as in an average Thor is not going to be hurt by c$ explosives and is significantly stronger than anyone here, if you take his best he is stronger than everyone here combined multiple times over.
He is still a skilled combatant in his own right, much more than a brawler like Hulk. He has also shown the ability to run and react at superspeeds.
Also when he doesn't have his hammer Thor tends to make better use of his of physical abilities instead of just engaging in standard punching contests.
I haven't seen anything in the past 2 years to lead me to believe Thor is going to do much more than brawl in a situation like this. Maybe thunderclap and get rid of some of the extra baggage of the opposing team, but he hasn't shown much strategy outside of battlefield removal, which is being disallowed by the OP and which he doesn't have without Mjolnir anyway. (Right? Or HAS he in fact created portals, etcetera without his hammer...? Honestly don't know.)
As for "Thor is stronger therefore wins" ... hmm, can't quite agree.
He's been one-shotted by non-World War Hulk, and beaten with his own hammer into submission by Red Hulk. Last I'd seen of Ben, however, the FF brick was taking on Colossalnaut and Namor ... and giving a good account of himself, too.
Regarding the C4, though, I thought I made it clear the purpose of the explosive isn't to injure him. Maybe it couldn't do so in any real sense, just as you say. However, judging from what I've read of Thor, it's NOT true he'd be unaffected by something so powerful going off in his ears and face. Even Classic Thor was shaken by less an ordeal than that would be; and that was in the days where Thor's prowess was generally HONORED by creative staff ...
