You know what? One of the worst parts about liking underappreciated Pokèmon is the frustration when you see others saying how much they hate them. I personally really like Carnivine, Drapion, Tangrowth, Purugly, Skuntank, Probopass, etc, and seeing all of them being hated in this thread is disappointing.
Honestly, I'd say that the only 4th generation Pokèmon I dislike are Garchomp and its pre-evolutions, Lucario, Croagunk(but Toxicroak is... okay), Bronzong, and Lumineon(but Finneon is cute). Bidoof and Bibarel are pretty cute to me, but it's hard to like something that is a meme.
