Professor Samuel Oak (Japanese: オーキド・ユキナリ博士 Dr. Yukinari Ohkido) is a Pokémon Professor who lives and works at his research lab in Pallet Town of the Kanto region. According to Professor Elm, Oak concentrates on Pokémon and human relationships as a profession.

In the core series

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 Pokémon Masters EX, 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.

In his own Pokémon Masters EX Sync Pair Story, "A Day With Professor Oak", Professor Oak reveals that his trusted Pokémon partner is a Nidorino.

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.

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 MN 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).

Professor Oak will have a team consisting of five Pokémon. His four guaranteed Pokémon are as follows:



In addition, Professor Oak will use one of the following three:

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.

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 entered the Hall of Fame.

The Pokédex is one of his inventions: new Trainers receive one, and a Pokémon to boot, when they start out.

Trivia

  • Professor Oak has appeared in the most generations of any Pokémon Professor, appearing in Generation I and their Generation III and VII remakes as the regional professor and making cameo appearances in Generations II, IV, and the Generation IV remakes in Generation VIII.
  • If the player speaks to Professor Oak in Pokémon HeartGold and SoulSilver and has their Pokédex evaluated with at least 484 of the 493 Pokémon caught, he will say "Meeting you is something l will cherish all my life long.", using a lowercase L instead of an uppercase I.
