Luvdisc - Nice and all, but please give pokemon decent... somethings. I can't even think of a redeeming evo for it. At least give it a pimping breeding group so its like the new Fairy/Ground, just in the water.
Dusknoir - Please don't give pokemon who make it as a fearsome foe in the UU tiers an evolution. Give it to something thats stuck at bottom UU or NU, such as Banette.
Probopass - Where did that mustache come from? Though, it is hilarious. But it still sucks.
Magnezone - I already liked Magneton, and we didn't need to have an evolution like this.
Shaymin - Elch. Atleast make the sucky hedgehog pokemon blue, have good speed and crappy everything else. Then we can laugh at it.
Rhyperior - Needs to be less awesome. Seriously. Rhydon was incredible as is, but Rhyperior kind of takes the entire cake for himself.
Weavile - I hate him. Sneasel had great stats, but no moves to support him in the ADV generation and such. But now, he was geared up to live the good life in UU. Then Weavile comes, and makes him OU.
Lumineon - Atleast be a Water/Bug for comedy or something. Nintendo, you had a good design with Fineon and all, but why give it such a terrible evo design?
Hapinny - Good idea, but I think the only purpose here was so that Chansey would be out of the Petite Cup. Atleast, thats the only reason I can think of...
Mr. Mime - Mime junior is awesome. But Mr. Mime isn't.
And Wurmple, Purugly and Bidoof are necessary. Every generation has to have its Rodent, Cat and Bug. I just wish Bidoof and Purugly were less... hideous.
