In the games

In Generation I

The unused Trainer class for Professor Oak

Professor Oak works in his Laboratory in Pallet Town with his aides. He gave Red and Blue their starter Pokémon in Pokémon Red, Blue, Green, Yellow, FireRed and LeafGreen. He is an idol to many Trainers and researchers, including Professor Elm, and always plays an important supporting role in the many games that he appears in.

He was a childhood friend of Agatha. They remained good friends and top-class Pokémon Trainers until Oak stopped battling and became interested in Pokémon research. Agatha said that he became soft and started to regard him as a fool. However, Oak still affiliates with the Pokémon League as an adviser. In Pokemon Masters, during her Sync Pair Story "A Day with Agatha", Agatha explains how she and Oak met. Oak was always friendly and open when he was young and would talk to Agatha and try to help her. Though he was only trying to be nice, it still annoyed Agatha because she wanted to be left alone. Agatha would battle Oak to try and get him to go away, but he was always better than her, and so she would battle him again and again. Eventually, the time they spent together began to mean a lot to Agatha. As a result, when Oak got the idea to invent the Pokédex and subsequently stopped battling, Agatha felt betrayed.

Pokémon

Red, Green, and Blue

Professor Oak confirms having been a successful Trainer in his youth; however, he states that he only possesses the following Pokémon. Red is allowed to choose one in order to begin his journey. His grandson, Blue, the player's rival, then picks the Pokémon whose type has an advantage against their own.

Types: Grass Poison Bulbasaur Lv.5 Tackle Normal   --       Growl Normal   --       Struggle Normal   --       Struggle Normal   --

Type: Fire Unknown Charmander Lv.5 Scratch Normal   --       Growl Normal   --       Struggle Normal   --       Struggle Normal   --

Type: Water Unknown Squirtle Lv.5 Tackle Normal   --       Tail Whip Normal   --       Struggle Normal   --       Struggle Normal   --

Yellow

Main article: Red's Pikachu (game)

Professor Oak catches this Pikachu while stopping Red from beginning his journey without any Pokémon. He later decides to give it to him.

	Type: Electric Unknown
Pikachu Lv.5
ThunderShock Electric   --       Growl Normal   --       Struggle Normal   --       Struggle Normal   --

This Eevee was intended for Red but was taken by Blue in his impatience. Its evolutionary path is determined by the player's interactions with its Trainer.

	Type: Normal Unknown
Eevee Lv.5
Tackle Normal   --       Tail Whip Normal   --       Struggle Normal   --       Struggle Normal   --

Unused teams

In the Generation I games, there is unused Trainer data for Prof. Oak. This implies that the player was supposed to battle him at some point in the game.

In the data, Oak has a level 66 Tauros, level 67 Exeggutor, level 68 Arcanine, level 70 Gyarados, and one of the Kanto starters at level 69. This places his strength a handful of levels above the player's rival and the Pokémon League Champion. In addition, four of his Pokémon are identical to the ones used by the Champion, only at higher levels, implying he was originally meant to be Champion, or at least another high-ranking Trainer. This is supported by an email on the PC in Oak's lab, in which the Pokémon League issues a challenge to all Trainers and specifically requests Oak to come visit them.

Oak can be battled by performing the Ditto glitch with a Special stat of 226 or by performing the old man glitch with ^M_N as the character in the 3rd, 5th or 7th slot of the player's name. These teams cannot be battled when using the old man glitch; they can only be battled via the Ditto glitch if the wild Ditto's Attack is lowered by 4, 5, or 6 stages (each will yield a different one of the three teams).

In Generation II

Professor Oak was always well known in Kanto but in Generation II he became more of a celebrity, a "star Pokémon Researcher". He became famous in Johto because of his Radio Show with DJ Mary. He was going to turn down the show at first but Mary's energy and persistence wore him down. Ethan/Kris first met him visiting the home of Mr. Pokémon, another of Oak's childhood friends. Later he grants the young Trainer access to Mt. Silver, a place which only the finest Pokémon Trainers may enter, after the player has earned all the Badges in Johto and later Kanto.

Professor Oak has many old friends. One of them is Kurt, a Poké Ball smith from Azalea Town and another is Professor Elm who used to be Oak's assistant. In fact, there is a picture on Kurt's wall saying "...a young Prof Oak?" and an email addressed to him from Professor Elm can be found in his lab:

"...

Prof. Oak, how is your research

coming along? I'm still plugging

away. I heard rumors

that <player> is

getting quite a reputation.

I'm delighted to hear that.

Elm in New Bark Town 8-)"

Professor Oak has gained many fans and admirers. One of them is Schoolboy Chad, who frequently calls the player to share trivia about Oak.

In Generation III

Professor Oak returns in FireRed and LeafGreen to reprise his role from the Generation I games. He also grants the player the National Pokédex after they have caught 60 different species of Pokémon and defeated the Elite Four.
