Hrm. Tricky.
1. I think I’m probably going to go with Pinsir, although he might be less ‘least favourite’ and more ‘most forgettable,’ partly because Heracross exists.
2. Snubbull. I never quite ‘got’ the whole “pink fairy bulldog" thing.
3. Nosepass. Yes, I know it’s based on a moai statue. Yes, I know that’s exactly the kind of cultural allusion I normally like. Whatever you wish to point out to me in Nosepass’s defence, YES, I KNOW! No, I still think the idea of a Pokemon that uses its enormous magnetic nose to keep itself pointed north is dumb.
4. Probopass. I hated Nosepass so much, and then they went and evolved him, made his nose bigger, gave him a moustache, and attached three ‘mini-noses’ to him, thus winning him the dubious honour of being the stupidest Pokémon of the generation for two generations running, something I hadn’t even thought possible.
5. Garbodor. I don’t particularly want to open the whole argument again, so I’ll just give you the link.
