Are there Pokémon that you just don't think could be cute in any way?
To me, a lot of legendaries are ugly, like the ones put above. I really don't think that zekrom, arceus, palkia, dialga, well, I guess basically every Pokemon that is the main legendary of a game. I've never found Pokemon that seem to try too hard cute, either (pachirisu, stunfisk, victini, ect). And as said before, almost all of the ghost and fighting types aren't cute either (except for gastly, misdrevous, riolu, and even some sableye.)
