Huh, I guess the only Grass types I've ever used have been starters...I never noticed. I like Grass types, but they have a lot of weaknesses, and their advantages can be covered by other things, so maybe that's why I don't train them as often. That being said, possessing a Serperior in Black 2/White 2 makes Humilau City Gym a complete joke. Definitely too tough to pick a favorite here, what with the bond one forms with their starter being special and all.

Psychic is next.
