i dont think spawn would have any trouble catching superman
i really dont see superman beaing beat by the T-1000 though, superman has already been beat down by everything the T-1000 could replicate and was uneffected, its liquid steel that can be killed VS steel that cant, Im sure theyd battle for a damn while before supes figured out that molten lava would kill him but he'd figure it out, that would be nice though to see superman get killed from the T-1000 liquifying himself and finding away into supes body and then suddenly harden and explode out of superman that would be nice death if he could pull it off
