Pokemon Zombies [Kanto region]

What is your name? Are you a boy or a girl? [portable radio] Hello, let me introduce myself, I'm Professor Oak from the singing region, I'm sorry I can't be here to give you your starter. I got infected and I don't have much time, so choose one of the three pokeballs on the table. There's a charmander, a squirtles and a bulbasaur. , choose well since once you have your starter the security system will lock the other two pokeballs, don't worry the other pokemons will be fine and will wait for a new trainer. Whoever you are, I wish you luck. The only thing I can tell you is that this started with a fossil found in all regions... good luck you put away the portable radio and say goodbye to the professor which pokemon do you choose?
