I love five of them
Whitney, Falkner, Bugsy, Morty and Clair
With Whitney, I like her because she's summery, cute and girly. I like her personality and her outfit and she makes a great farmgirl.
With Falkner, it's in between his love for birds and his interesting unique appearance. He's hot half the time and weird-looking half the time. I guess the animation in his episode wasn't too great. But his personality and how he was done in the dub made him awesome.
Bugsy, he has girlish charm. He's also got that androgynous charm to him. He has cute jokes and awesome hair. And he's great jailbait!
With Morty, it's that whole hippies-rock thing going on. He's got that whole ghostly vibe too, not to mention he's friggin hot!
Clair.... well, she's beautiful and has such a unique beauty that not too many people on Pokemon have. Not to mention Kaburagi pwns.
Chuck and Pryce are cool too, but I dislike Jasmine.
