The Best Fighter
Ok here's the situation. Every single character from Marvel and DC gets upgraded or downgraded to Superman's level of strength. Every other power is non-existant. Solely strength, that means no flying, no matter manipulation, no electromagnetism, no super-speed, nothing else - just Superman's strength, and whatever intelligence they previously had.
Example: Copperhead keeps his intelligence level (which isn't insanely high) and is upgraded in strength to Superman's level, but only has that strength, nothing more, nothing less.
Now the question is, who, out of Marvel and DC, wins the massive fight? Who is the best person to win this, seeing as they all have the same insane power level, and nothing more or less to take a different advantage besides their previous intelligence?
Nominees, just in my mind, but you're certainly not limited to this:
Superman
Batman
Captain America
Spider-Man
Dr. Doom
Reed Richards
Who do you think would win?
