Al is just...eurgh. He's so so creepy and his colouring is kind of disgusting ;-; I'll wail in sorrow if he ever moves to my town haha.
My second choice would be Hippeux.
I think Violet, Gigi and Rhonda looks pretty though!
Jambette and Diva are so hilariously bad that they loop back around and become good.
I don't think Rhonda's that bad, actually. Her color scheme's actually pretty nice.
Al is the most disturbing by far. Something about that guy just gives me a primal fear that cannot be explained by modern human language.
