Jigoku no Pikachu
Pardon me if I sound like a monologue from Linklater's Slacker for a second, but hear me out. "Pokémon" is a sort of shorthand for Hell. Think about it: a world made of nothing but semi-intelligent beasts who all repeat their own names, wandering about aimlessly just to beat the snot out of each other. It's like they made a cartoon out of Beckett's How It Is. Substitute any of the critters for a homeless guy dragging a garbage bag saying, "Floyd, Floyd, Floyd." Then have him beat up another clutching a bottle of hooch mumbling, "M-M-Murph, Murphy, Murph." How you like them Mudkips?
