History
PM series
Kanto
Professor Oak first appears in Clefairy's Debut!!, in which he calls in Green and Red to his lab to get their first Pokémon. Green beats Red to the lab when they were racing. When both Trainers were in the lab, Oak tells them the news (other than the fact that he is bald) that he is requesting them to go out on a journey to fill up the Pokédex. Afterwards, he gives them each a Pokédex and gives Green a choice between three first partner Pokémon, a Bulbasaur, Charmander and Squirtle, in which Green chooses Charmander. Before Green left, a Clefairy comes in. Oak did not allow that Clefairy in the lab as he was known for causing mischief. Clefairy calms Oak down by massaging him, making him forget what happened. As it was Red's turn to choose, Red decides to choose the Clefairy as he enjoyed Clefairy's silliness.
In Will You Risk Your Life to Play the Magic Game?!, Professor Oak tells the two Trainers about a legendary Pokémon, Articuno in the Seafoam Islands, where it made its major appearance in the next chapter.

The prize turned out to be Exeggcute which chase Red and his pals away.
In Clefairy Evolves... At Last?!, Professor Oak contacts Red that he is on his way. Red laughs at him, as he doesn't believe that Professor Oak is telling the truth.

He also gets to reunite with the Eevee that he used to have, as it was now use for experimental purposes relating with its evolutions.
