Akuma is that dude. He's the one shoto character we know who prefers to whoop ass with shoes on. Let that be a lesson to you other shotos! Real men don't fight barefoot! The Raging Demon is a bona fide killer when you're pulling off his super rendition.
But when Akuma is feeling extra violent, that's when we do the unthinkable. Skate on one foot, smile for the camera, then commit unspeakable horrors in the darkness of hell. We don't wanna know what Akuma's actually doing to his opponent during that whole sequence. Some things are best left to the imagination.
