Origin
Professor Oak is seen at the beginning and ending of the game, making him very important in the story. He also gives away Pokémon and items on a regular basis. This has led to rumors about him giving away PokéGods or special items, including his custom Poké Ball. Interestingly, researchers in later games give away rare Pokémon after certain requirements.
