Oh, well, in that case…
Doom would work but not really. I think you could display it with white, orange, cyan, and green attacks, but imo, “running” doom means being able to play it, which I don’t think is possible in the battle box unless some shenanigans happen with the soul.
Bad Apple works. People have done it already. There was a video I watched where you play as sans, and the final fight was just bad apple.
