[Optimus Vader]

Who would win what? Who would win in a fight? Are they in their superhero gear for the fight, or just bare-knuckling up? Or is it "who would be the one who got the winning bid on a contract/job?"

If they're fighting with their suits/gear, I don't see how Tony doesn't blow Bruce up in about two seconds, but if it's just dude vs. dude without their suits, then Bruce would win in about two seconds.

If this is a financial battle of some kind,.. flip a coin. If this is a battle of intellect, or battle of brains to "earn" a contract, then I don't see Morgan Freeman out-inventing Tony. If he could, he would've invented Ironman's suit for Batman to use instead of giving him spelunking gear and a car that can jump over broken bridges.
