A good rule of thumb is you can’t have more than five people fighting against a single person at once. They’ll just be getting in each other’s way and not adding to the overall force being directed against their single opponent. Even five is too much unless they have some experience fighting as a group against a single person.
The best strategy for a group fighting against one person is to not have everyone fighting the person; tell each person in the group to fight one limb. You say “Your job is to get control of his right arm” and repeat it for all four arms and legs. If he’s got a weapon like a club, you assign one person to get control of the club.
I’ll admit I’m not sure how well this would work against a single person who’s ten times as strong as a regular person. You’d be in a situation where in terms of strength, the group would be the outnumbered ones. And you can’t just add more people for the reasons I’ve already mentioned; ten or fifteen people don’t fight any more effectively than five people.
To the OP: superman loses, assuming no superhuman durability to go with the strength. Ten opponents could surround him, and some could get shots in from directions he cannot defend himself against. If they have weapons, superman loses. A baseball bat to back of the head hurts, even if you’re strong enough to break that bat with your bare hands.
Captain America in MCU clearly has superhuman strength. His helicopter feat required at least 3,000 pounds of force and was strong enough to use a motorcycle as a throwing weapon; his attackers couldn’t match up to 300 pounds each, most likely. (Very few people are that strong. Batroc, maybe?)
He also demonstrated super-human fortitude. Tasers had a much less effect on him than they would have on most people. Also, he can fall 30 stories or so and be completely unaffected. He wasn’t just strong, but tough, although not so tough that cumulative injuries could hurt him. They should have just put an anti-tank mine underneath the elevator.
The OP explicitly says he has 10x strength and durability. It wouldn’t make sense if he had ten times the strength of a normal man but had normal human durability.
Definitely don’t attack him ninja style, one at a time, waiting until each ninja is down and out, then giving the guy a chance to get set before the next ninja attacks. Even if it looks like a reasonable strategy it just never works.
Actually I’ve been wondering how to mention, weapons are fantastic force multipliers. I haven’t done any of the math, but I wouldn’t be surprised if a knife could penetrate 10x stronger skin, particularly if it’s a nice long knife (read: sword) that they can get some mechanical advantage with.
And of course if somebody brings a gun to this party it’ll be a short party.
This is a person 10x as strong as a normal human. Think of a martial artist trying to “kill shot” an enraged chimpanzee or baboon. And they are only 2x to 3x a human strength.
I’m not sure how big the parking lot is supposed to be, but I think it’s going to be a lot more than tens of people.
The 10x person is going to be much faster than the others, which means that the group is going to have a hard time positioning themselves to encounter him in a group. If they stay in a group, he can likely just evade them. If they spread out, he can attack their flanks or individual members. And the 10x person can likely easily handle 100 or more in sequential 1-on-1 combat.
