Favorite: Gary, Tracy, Misty, May, Max,Team Rocket (the Jessie, James, and Meowth trio), and Lance
Umbry, I know you don't like May too much but I can relate to her becasue both her and I have a little brother who's a bit smarter and times but she cares for him and looks out for him. Thats also the same reason I like Max.
Tracy likes sketching and drawing and I think thats neat. Maybe I like Sammy (young Oak-san) too becasue he does nearly the same thing.
Gary is just plain cool and evern though he was a stupid-arrogant-showoffy-bstard at first, when he stopped being so arrogant he was awesome! Not only that but he's got some pretty cool pokemon too.
It may be a bit odd to like the "bad guys' but they are so fun to point and laugh at. Ash, if you laugh at him you'll be mobbed and critisized by kindergardeners but at least if you laugh at these guys no little kid gets mad at you.
You have to admit Lance is awesome! He has cool pokemon and everything! So what if hes a perfect freak hes actually a lot like Kratos from Tales of Symphonia. Both are cool, perfect, showoffy redheads with hair that is either overflowing with gels or grows naturally in a defying-gravity state, same with Sasuke from Naruto but his hair is black. I suppose lots of animes have people like this and they all seem to have an association with tomatoes (actually thats only Kratos and Sasuke).
