Uhh....Green (male).
I just like him coz he's like a more intelligent Red *shot*
Seriously though, I've preferred him right from the start, when he gave up against Mew. Whereas Red was like most players of the game: "aaarghlegendaryimustkeeprevivingmypokemonsuntilicancatchitwhocaresiftheydie"
After that, it's probably Gold and Red. I like all of Red's team, and him as a person. I like most of Gold's team (not too keen on Sintaro, should've stayed un-evolved, I loved it like that. Although it did have a brilliant evolution - standing on top of Mantaro whilst using Sunny Day), and he's funny, even though if we met we'd fight. a lot.
