Who's your favorite PLAYABLE CHARACTER?
Touya, the male player character in B/W for those unfamiliar with the name. I prefer the coloration and attire to the other characters.
Who’s your favorite GYM LEADER?
Sabrina, for some reason... possibly because one of the first anime epsodes I saw included her. She uses cool Pokemon too (barring Jynx, ugh).
Fuuro and Kamitsure are nice too. Blue is cool and has a good backstory (possibly my favorite Rival too, since he fits both categories).
Who's your favorite IN-GAME CAST CHARACTER?
Riley, probably. He's got the best team of all the trainers that appear in the Battleground cafe, he gives you a free Riolu egg, and has some Aura powers.
Who’s your favorite ELITE FOUR MEMBER/CHAMPION?
Lance and Cynthia. Lance uses my favorite type, and Cynthia is both powerful and hot.
