Hi, I'm back and I've got another minger or two to add to my list.
I know this isn't going to make me popular, but alot of the fully evolved starters are hideously ugly. The Hoenn trio particularly. I'm never evolving my Grovyle*clings* If you wish to argue, you are free to PM me.
To those of you who said Feebas, that critter is too bland to be ugly, although it is a very interesting concept. Pelipper, on the other hand, is one ugly bird. The wierdly shaped head, the disproportionate body, the cardboard wings, the freaky eyes, and worst of all, that oversized mouth.
People have mentioned the likes of Ursaring, Nidoking, ect, remember these critters were designed to be intimidating. When I use ugly to describe a pokemon, I usually mean badly designed, or just plain freaky. Like Nosepass.
(Struts off, boiling with Nosepass hatred)
