Chespin

Chespin is a Grass type Pokemon. In Pokémon X and Y, it is one of the Starter Pokemon in the Kalos region. If the player chose Chespin, the first Gym Leader will be difficult to battle, since Viola, the Gym Leader, specializes in Bug types.

It evolves to Quilladin starting at Level 16, and into Chesnaught starting at Level 36.
