Who would win?

Base SupermanvsBase Thor

Base Superman
The short answer
Superman wins

Thor has the right weapon for this fight: Superman is vulnerable to magic, and Thor's lightning and his enchanted hammer Mjolnir are magical. That gives Thor a real edge, but not enough. Superman is two tiers stronger, and Thor can't hurt him enough to end the fight, while Superman can put Thor down.

  • Thor's magic is Superman's weak spot
  • Superman is two tiers stronger
  • Thor can't finish Superman; Superman can finish Thor

In short

Superman fights at a level Thor has to reach up to, and the gap shows in every exchange. Only Superman can put Thor down. Thor has no route that works here — everything available is either stopped or survivable, so Thor cannot close the fight out. Only Superman has a valid win condition (a kill, a hold or a shutdown) — Thor cannot end the fight. Superman wins comfortably — there is no real argument in the other direction.

The tables below show every check behind this, with the numbers the engine used.

A kill lands only when the attacker's reach meets or beats the defender's resistance. Containment must clear two bars: it has to out-reach the opponent's escape and reach 8 to hold permanently — below that it is a temporary hold that lapses. A fighter who fails both cannot end the fight, however much damage they do — which is how an outmatched fighter can still force a stalemate.

Can they threaten at all?

SupermanYES
ThorYES

This checks only whether a fighter can meaningfully attack at all. It is tested before the win conditions above — so a fighter can pass here and still have no way to finish the opponent.

Rulings

Superman is rated at 5 for resisting seals, prisons and banishment (escape 0 -> 5)
Superman has no rating for resisting being knocked out or shut down, so it is read from their tier as 7 rather than as none (incap resistance 6 -> 7)
Thor is rated at 3 for resisting seals, prisons and banishment (escape 0 -> 3)
Thor has no rating for resisting being knocked out or shut down, so it is read from their tier as 5 rather than as none (incap resistance 2 -> 5)
Thor is rated at 3 for resisting mental shutdown (mental resistance 2 -> 3)
Only Superman has a valid win condition (a kill, a hold or a shutdown) — Thor cannot end the fight
