Roark because he's my boyfriend he has a Cranidos: the most adorable Rock-type Pokemon in the WORLD (besides Cradily)! Plus, I absolutely love Ground and Rock types :)
Fantina for being French & having one of my favorites - Fuwante / Fuwaride. Her hair also amuses me.
Aaaand, uh Maylene because she has a good design and I fell in love with her after that escapade in the snowy route. Barefoot and lighty-dressed... Oh, the courage!
Aaron in the Elite Four. Bug-types are great too, but I especially like his Poison-types. Best design imho of all the E4.
RAGE@Cynthia. No. Bad girl. *slap*
Aaand, for the Frontier Brains. Well, I wouldn't know, but Darach is a funny one.
