But I also caught a Caterpie, evolved it to Butterfree and it's been a lifesaver against early Poison types like Koffing, Ekans, Grimer, and Zubat you find against NPCs. I wish it could learn a Bug move early to take out Misty's Starmie.
I recently started playing LeafGreen again too, and picked Squirtle since I normally go with Charmander since I love using Charizard later in the game. If you need help dealing with Misty's pokemon, try catching a Pikachu in the Viridian Forest.
