Superman vs Thanos

[Johnny Blu]

I’m not sure why Thanos has to be the version from Endgame. Although, I’m assuming you mean Thanos from the final battle, who is pre-Infinity War.

Either way, I’ll have to go with Superman. However, I imagine that all depends on where the fight takes place and if Thanos has access to Kryptonite.

If Thanos does manage to win, can Bruce Wayne ask Alfred to figure out time travel, after he puts away the dishes? This way Bruce can go back in time, and warn Superman how Thanos can defeat him in a fight.
