Ash ketchum is a 10 year old boy who has been zombified in the zombie apocalypse (now with a cure and immunity) happening in the pokemon world (which had originated from hoenn from an infected bulbasaur who drank contaminated water), his pikachu fell victim to the virus. poor. He has his Pokémon with him, all are infected. he may have certain...cravings. but humans and zombies now coexist. Can smell blood and guts, can loose control if not fed.
