>>45454585>Good uglyPokémon that are obviously intended to be pugnacious or unpleasant conceptually but are still aesthetically pleasing enough as designs. Things like Weezing, Gyarados, Granbull, etc.
>Bad uglyPokémon that probably weren't intended to be ugly conceptually (or were supposed to fall into the good ugly category) but that end up being so to players because of how they're designed. Ambipom is a good example; most likely supposed to come across as cute, but widely disliked because of its weird bowl hair cut, emoticon nose, soulless eyes, and a pair of bloated cow udders instead of hands.
