I'm afraid I can't vote here, since I don't hate any of his Pokemon. Why must such negative hate threads exist? lol
Hating Torkoal because it is emotional, and hating Bayleef for it being so lovey-dovey just seems negative to me. I actually like Ash's Bayleef a lot.
All of them are perfectly fine, and the only one that is actually flawed is Pikachu, since it can make unfair move, and the annoying part to it is that it gets back to square one every region...
