Yeah, this fight seems to be down to whether or not Devil Mario's hax is actually even effective or not. And most of it really isn't.

His magnum opus' here would be Possession, Immortality, and the resistance to Soul Manipulation. So, in the end, Optimus gets by his best stuff with speed and A.P. in check. What now?
 * Possession won't work since we've never seen Devil Mario possess a robot. It'd be burden of proof to assume that they could without any evidence.
 * Immortality's disabled here due to the form used.
 * Optimus doesn't have anything to attack souls.

Well, Devil Mario does have a last resort to use here. Since he can throw out his Boos to attack the enemy, he can send out hundreds of Boos to attack Optimus from all around. It could legit become 1 VS 100 instantly, and then to stack on top of that, the Boos can't be hurt since Optimus has no way to harm souls. In the opening to Power Star, they even entered Mario and directly attacked his soul, so...who's to say they can't attack Optimus from the inside here? They'll both probably be caught up first in their honor and arrogance, but that'll be dealt with pretty quickly once they realize their foe is worth something.

...In the end, I have no clue who'd win this. Sorry, but I gotta vote Inconclusive. Optimus has a lot over Devil Mario himself, but once the Boos are out, it gets much easier for him to lose, so I don't know who'd kill the other first.
