Okay, I’m not actually going to scour the internet for this one, but I know there has got to be a M.U.G.E.N game out there where you can battle as different Pokémon, right?
There sure is, or at least there is one in the making.
Project catch ’em all, where you are the trainer giving commands.
Or else you could still try Type-Wild
Not M.U.G.E.N,, but it’s a fighting game where you actually use the pokes.
