Im going to explain
*ROGUE : superman would rape her but thats all it takes is one good touch and the fight is done. Like I said if a slower rogue (parasite) can get the drop on superman then rogue should grab him with no problem.
*Jean grey (phoenix force): I dont even have to explain on this fight, she destroys him.
*STORM : Lightning is the main key in this fight because electricity hurts superman extremely bad. I have seen him yell in pain to many times because of it and the rest of storm powers would just play as a nuicance while she lay into him with lightning bolts.
*Magneto for sure with a majority (magneto wins this via forcefield and hitting superman with enough force and explosion that he ends of losing his bio forcefield ending with him passing out. Like i said before, a guy on the fatal five blew the groud up from under superman ending with him bleeding from the mouth. Magneto has a lot that he could do to him to make him pass the f*** out.)
*Proteus (this fight is a rape. Proteus would kill superman. Proteus would kill the entire jla. The guy has NO weakness and he can turn or do whatever he wants to superman).
*Cannonball: (To me this is the fight of the century if he uses his powers right. He absorbs kinetic energy, that means he absorb anything that superman throws at him and turn it back at him. Superman would end up hitting him with a powerful blow ending with cannonball laughing it off throwing it back at superman with the same force knocking him out. There is nothing that superman could do to him.)
*Cable; (Cable already has a forcefield that is always up that can take nuke blast and that also withstood punches from a angry hulk, I doubt superman could do any better. God like cable could either bfr superman, take his powers away, or mind rape him. Cable displayed the powers to do almost anything. It was stated that he had no limit (except to cosmic blast which superman dont have.)
*Nate grey (another rape, superman stands no chance in this fight. The same results would happen as would against cable except worse in this scenerio.)
*Scarlet witch (anything she thinks of comes to reality. Do the math.
*Exodus (this guy fought the avengers and stalemated sersi. Has a impenetrable force field and blast that was stated that could level half of the earth. Superman loses this one.
*Apocalypse (non jobbing apocalypse can beat superman everytime. non jobbing apocalypse can be a jla threat. Nuff said.)
*Professor x (mind rape
*Iceman (freeze superman entire insides or just go inside of him ripping his insides out. To muuuuuuuuch versatility and power)
*Vulcan (good fight, I see superman getting the majority but I think that he could get some wins.)
*Full powered Mimic (Mimic recently is just as powerful as superman. By bio mimic is faster, Im going by Dc and marvel encyclopedia. It simply state in both that superman top speed on earth is 2000 mps and marvel ency says that he can go 93000 mps. Mimic has been moved up to colossus level of strength, over the 100 ton league and is nigh invulnerable and has eye blast of his own with an insane healing factor. He could pull off some wins.)
*magician (the same as proteus. This guy physical body wasnt even present when he was fighting the xmen and he could just create the entire jla along with another superman to beat the hell out of superman)
*Gorgon (I dont think that gorgon could out fight superman but i do think that his eyes would work)
*Emma Frost (Emma frost is nigh invulnerable, If superman dont take her out on the 1st punch he gets mind raped to death.)
*Rachel summers (Same results as phoenix, supes dies)
*Wolverine from age of apocalypse (not logan. This guy was a villian) (To many people dont know about this guy but he was basically unstoppable. There was nothing physical that could stop him. If superman was to just stand there and fight him superman would lose. Hes another Doomsday. But if superman fight him and try to bfr him then he could win.)
*New Sun (New sun speaks for himself)
