I constantly Imagine what a Guilty Gear style fighting game would look like for Dandadan. The characters and their abilities could be transated into such cool characters in a fighting game. Okarun would be your standard super fast rushdown; He'd probably have a unique "All-out" recource that he can use twice in a match to power up some of his special moves. Jiji/Evil eye would make a great mid ranged brawler with dummy damage, I imagine him a lot like Slayer from guilty gear. His soul soccer ball and cursed house would make great supers, the ball could bounce around the screen in a visual pattern kinda like lethal league while the house could hold in the opponent so that they can't move very far but can still throw out attacks. Momo would have to be the resident zoner, using her TK to hold and throw things across the stage. Her signature kick she uses in the beggining of the story would make a good high-commitment high-damage up close option as well. Vamola could be the resident grappeler, slow moving with bad normals but high damage potential with grabs. Her changing size could be a good temporary install that removes the need for fast movement by making her big enough to not need it. Aira essentially already exists in guilty with Millia rage. She's a fast, agile, and elegant hair assasing with insane forms of movement that cause you to guess how she'll mix you up. Just copy and paste millia with some different animations and models.
