What kind of personalities and so forth do you think they'll have if they're human?
I've been having this subject on my mind for a while now. I know, I'm weird.
Anyway, for some reason, I think Tentacools/Tentacruels would be Latinos. Maybe it's because of their color. Hmm.
Also, I think Croagunks/Toxicroaks would be like jocky perverts to me. Not sure why. And Infernapes would be the jokers of Pokemon. Something about them make me think of them like class clowns.
