Which pokemon has the least pretty preevovled form

[natprirodan]

I'm making a video for Youtube on ugly/scary pokemon becoming pretty.

I already have my ending pokemon, my Feebas named Pretty evolving into a Milotic.

I can't decide on the others. I'll need about 10 all together, maybe a few more.

Slugma [though I think it's cute xD]
Slakoth

I think slugma's cute too. But he is a good one for this, even if he only gets scarier.

And thought of something, for the opening, before I start the music, using a scene from the third or forth episode of pokemon, when Ash catches his caterpie and Misty runs away scared of it. Then end with the scene where it evolves.
