In the game Pokémon FireRed and LeafGreen and in the game Pokémon Red and Blue, Professor Oak lives in Pallet Town and he is absent from his lab until you try to leave town, when he runs up to you and makes you come with him. He then lets you choose a Starter Pokémon. If you go to the mart, the store clerk will give you Oak's Parcel. The Parcel contains a prototype Poké Ball, bring it back to Oak and he will give a Pokédex to you along with 5 Poké Balls. He sends you on your journey and all throughout he helps you by sending his aides out to give you items if you capture the right amount of Pokémon. In Pokémon FireRed and LeafGreen, he helps you when your rival challenges you for the first time.

In Pokémon Yellow, when the player steps into the grass they will encounter aPikachu, which Oak captures and gives to you after your rival takes the Eeveethat was intended for the player.
