I've been thinking of doing somethin' w/Turles lately.
(Maybe a movie 3 parody set in the present of my fics timeline)
I haven't seen the movie in a while but I'm pretty sure at the beginning he's got a Piccoloesque cape.
An evil villain who looks exactly like Goku feels like it has quite a few fun possibilities...
The fact that he tries to take over the world using food products is great too.
