Treecko is one of the gen 3 starters and is a grass type. Treeckos evolve into Grovile and the Sceptile. They start out with the attacks pound and leer. Treecko was one of my favorite starters as a kid probably because I used to love grass type pokémon. He is pretty strong and is really good when he levels up. I really like the combination of grass type and his lizard based design.
