And here it is finally, the winner of that poll I made a while back: Mario vs. Crash Bandicoot.
I'd argue that the strongest Crash visual (at least from someone like me who's never played any of those games) is the spin attack so that was my starting point. To make it even, I gave Mario the propeller hat which I think has more "spin factor" than the cape from Super Mario World. I threw in a generic forest background and radial-blurred the hell out of it to avoid rendering it (because I'm lazy) and called it a day.
In the poll, Earthworm Jim came in second but I got a cool idea and visual for a Mario vs. Sackboy piece so that'll probably be next.
