Suggested by iKnowledge Gladiator is a powerful fighter who once managed to defeat the Juggernaut. In the comics he has also held his own against Thor in the past so he shouldn’t be underestimated. That being said, All For One has taken on All Might in the past. He has many different abilities, all of which would prove troublesome for Gladiator. Gladiator’s speed and power will let him put up a pretty good fight, but in the end All For One will have an answer to every possible attack pattern and a counter attack to go with it. Eventually the hits will take their toll. All For One wins.
