Professor Samuel Oak (Japanese: オーキド•ユキナリ博士 Dr. Yukinari Ōkido, Ōkido-Hakase and Orchid are also seen) is a Pokémon Professor who lives and works at his research lab in Pallet Town. According to Professor Elm, Oak concentrates on Pokémon and human relationships as a profession. He is the only character in the games to have the Trainer class Prof.; however, it is impossible to battle him during normal gameplay, and this situation is only applicable to Generation I.

In the games

In Generation I and Generation III

Professor Oak works in his Laboratory in Pallet Town with his aides. He gave Red, Blue and Green their first 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 (some speculate that they were a couple) 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.

File:Wild Prof Oak.jpg
The unused trainer class for Professor Oak. However, in this case the game has not changed the battle mode data to a Trainer battle, so if "captured" he would be read as the last normal Pokémon encountered.

In the Generation I games there is unused Trainer data for Prof. Oak. This implies that Oak was originally going to be able to be battled. In the data, Oak has 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 on-par with the player's rival and the Pokémon League champion. As well, four of his Pokémon are identical to the ones used by the champion, only higher level, so originally Oak may have been intended to be in the game as the champion, or at least another high-ranking Trainer. This is supported by an email on the PC in Oak's lab, from the Pokémon League issuing a challenge to all Trainers, then specifically requesting Oak to come visit them. The only known ways to battle Oak is to use a special stat of 226 with the Mew glitch, or cheat. An alternate way is the Old Man Glitch. With the – symbol as one of those determining the wild Pokémon, he can battled as well.

In Generation II and IV

Gold, Silver, Crystal, HeartGold and SoulSilver

Professor Oak was always well-known in Kanto but in Generation II and Pokémon HeartGold and SoulSilver he became more of a celebrity, a "star Pokémon Researcher". He started to be 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/Lyra 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 finest Pokémon Trainers may enter, after the player has earned all the badges in Johto and later Kanto. In HeartGold and SoulSilver, he will give the player one of either Bulbasaur, Charmander, or Squirtle for obtaining all sixteen badges and defeating Red. He also gives the player HM08 (Rock Climb) to assist them in navigation through Mt. Silver. In Generation IV, he will also give the player the National Pokédex before boarding the S.S. Aqua. Finally, if both Kyogre and Groudon from HeartGold and SoulSilver are traded into the same game, he will give the player a Jade Orb so that Rayquaza may be caught at the Embedded Tower.

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 is his lab:

Prof. Oak, how is your research
coming along? I'm still plugging
away. I heard rumors
that <name> is
getting quite a reputation.
I'm delighted to hear that.
Elm in New Bark Town 8-)"

It should be noted that this is the first time that an emoticon is used in a Pokémon game.

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

Diamond, Pearl, and Platinum

Professor Oak is also a good friend of Professor Rowan. He visits Sinnoh often, has a home in Eterna City, introduces Trainers to Pal Park, and gives them the National Pokédex, as well as the Up-Grade, Poké Radar and the function Trainer Counter of the Pokétch. A letter that he sends to the player in a special event allows the player to find Shaymin. An aide in Rowan's laboratory mentions that Oak is Rowan's junior in terms of seniority. In Platinum, after providing the Up-Grade, Professor Oak will talk about the legendary birds and say that they have been sighted in Sinnoh. From this point Articuno, Zapdos, and Moltres will be visible roaming on the map.

In the anime

File:Professor Oak anime.png
Professor Oak in the anime

In the anime, Oak is most notable for his vast research facility, where he cares for and studies hundreds of Pokémon, including those owned by, but not currently traveling with, Trainers from Pallet Town. His often-forgetful attitude and other antics are also notorious. He also has a hobby of composing haiku-like poems about Pokémon or Pokémon-related themes.

Prof. Oak lives up the road from Ash's mother and the two often appear together as they are good friends. He currently lives with Tracey Sketchit, who became his loyal assistant in The Rivalry Revival. Tracey and Prof. Oak are very passionate about studying Pokémon and are both artists. He has confidence in his grandson, Gary Oak, but more often joins Ash's mother and friends in cheering on Ash in his competitions.

Oak is sometimes the candidate speculated to be Ash's father, along with Giovanni and Silver.

In the novelizations written by Takeshi Shudō, Professor Oak comes from a prestigious family. He has two brothers, one is the mayor of Pallet Town and the other is the Post Master, and his grandfather was the first Trainer from Pallet Town to receive widespread recognition. According to Professor Elm, Professor Oak's studies and research mostly focus on how humans and Pokémon interact with each other.

He is an old friend of many other Pokémon Professors, including Ivy, Elm, Birch and Rowan.

201 Spoiler warning: this article may contain major plot or ending details. 201
Sammy Oak

He appears as a young boy, Sam (Japanese: ユキナリ Yukinari) in the fourth film, Celebi: Voice of the Forest. Ash Ketchum befriends the young Oak, who, due to traveling from 40 years in the past, is around the same age as him. The revelation that Sam is Oak, while able to be speculated because Oak's first name was revealed in The Power of One, comes only at the end of the movie, when Oak knows that Ash's friend's name was Sam despite Ash never telling him so, and Tracey finding the sketchbook in which young Sam drew Pikachu sleeping with Celebi in Oak's closet.

In the movie, Sam saw many Generation II Pokémon, notably the legendary Pokémon Celebi and Suicune, though his Pokédex only catalogs the Generation I Pokémon, claiming that they are all the Pokémon that the world knows, in the Kanto arc. This discrepancy is likely due to the retcon that occurred when the 100 new Pokémon were introduced to the series, and due to the ever-increasing number of Pokémon, with Pokémon from Generation II, Generation III, and Generation IV being able to be trained in Kanto during FireRed and LeafGreen and HeartGold and SoulSilver, this is likely the reason that the number of them as of the current generation of games is no longer mentioned in the anime.

In side games

Professor Oak also was one of the two human characters appearing in Pokémon Snap. He was working on a Pokémon Report for the Pokémon species of Pokémon Island, and hired Todd to take pictures for the report. He provided Todd with the ZERO-ONE and its Dash Engine upgrade, Pokémon food, Pester Balls, and a Poké Flute. When Todd took a picture of each of the Pokémon Signs, Professor Oak drew a connection between them and the constellations to determine that Mew must be on Rainbow Cloud.

In the Pokémon Adventures manga

Professor Oak in Buzzing Elekid

Although Professor Oak's first mention was in A Glimpse of the Glow in a conversation between Red and some Pallet Town children, he is described as being an expert on all things Pokémon, however he is also "just a mean old nut". His debut was in Bulbasaur, Come Home!, where Red had wandered into his lab and was immediately accused of being a thief. In his haste, Red accidentally released all the Pokémon in the lab, including Bulbasaur, causing the two to track them down and re-capture them. After being saved by Red from a Machoke attack in Viridian City, Oak gave Red the Bulbasaur and a Pokédex. The professor also makes appearances in The Secret of Kangaskhan and Gyarados Splashes In!, talking about Team Rocket's experiments.He was then kidnapped by Team Rocket to force him to help them with their experiments, although he refused and they resorted to trying to use Blue to convince him, who later saves him. Oak later appears in Volume 3 to battle Green under the alias "Doctor O" and reveals Green's phobia of Flying-type Pokémon and her theft of Squirtle. However, he shows compassion by giving her the last Pokédex and forfeiting his position in the Pokémon League. He then forfeits after telling her that he has already won a championship.

In the Yellow chapter, he was talking with Misty about Red's mysterious disappearance when Pika wanders into the lab seriously injured. Yellow then barges into his lab uninvited. He then makes her battle him with his Spearow and is impressed how she defeats him without harming either Pokémon, giving Yellow his trust and as such he allows Yellow to take Pika and Red's Pokédex. Oak then sends letters to Blue instead of more advanced communication so nobody can track them. This was decided upon after Blue's encounter with Agatha of the Elite Four when she wanted to kill him after learning that he was Oak's grandson, although Blue was still unsure of how the two knew each other.

In the GSC saga, Oak is now known as the leading authority on Pokémon in both Kanto and Johto and has developed the three new Pokédexes. The first was stolen by Silver, the second and third he gave to Gold and Crystal. During the battle with the Masked Man, he gave out the titles to the six Pokédex holders and Yellow. At the end, he employed Crystal as his assistant and thanks to her, the Pokédex had been filled and he owned all non-legendary Pokémon for his research.

In the FRLG saga, Oak was captured by the The Three Beasts to lure Red, Blue and Green to the Sevii Islands; but not before he recalled their three Pokédexes. After he was freed at Trainer Tower, Oak upgraded the Pokédexes to add the National Pokédex capability.

One of Professor Oak's projects was a full analysis of a report holding all information on the last awakening of Jirachi. From this, he worked out that it would appear where the Battle Frontier was being built during its opening week. He immediately contacted Scott and, while he would not move the opening, Professor Oak managed to convince Scott to allow a Pokédex holder to guard Jirachi. This was Emerald. However, someone stole the disc with all the data from Professor Oak's lab.

His relationship with Agatha was also revealed when the two were younger. Oak defeated Agatha in the finals for the Pokémon Championship and Agatha met him after the battle and asked why he quit their "research group". He explained that he wanted to create the Pokédex, which she thought was a stupid idea that would never be complete, and a battle ensued. Oak barely won after a battle that lasted several hours, with Agatha swearing a personal vendetta over him and anyone who associates with him.


He has these Pokémon, or has owned them in the past:

In the laboratory


In the The Electric Tale of Pikachu manga

Professor Oak is Ash’s hero and Bill’s mentor. Ash meets him on Mt. Moon after wandering lost in the mountains for weeks, searching for a rare Clefairy. Oak, who has been living among the Clefairy, rescues Ash and introduces him to Bill and a tribe of wild Clefairy. The three attend the tribe’s evolution ceremony, after which Oak gives Ash the latest upgrade to the Pokédex for free, months before it will be available to the public. Ash later encounters Oak again in an unnamed city where the famed researcher is investigating strange activity (which turns out to be caused by another group of Clefairy), and at the Pokémon Research Center shortly before he travels to the Orange Archipelago. Here the Professor and Bill are researching a giant Slowpoke that was found in the Pokémon storage system.

Trophy information

The leading expert on the study of Pokémon. It seems there are always new and mysterious species of Pokémon being brought to light, and Professor Oak is at the heart of it all with his insightful research. The Pokédex is one of his inventions: new Trainers receive one, and a Pokémon to boot, when they start out.

  • Professor Oak is the only Pokémon Professor to have appeared in all released generations so far, appearing in Generation I and their Generation III remakes as the regional professor and making occasional appearances in Generation II and Generation IV.
  • Professor Oak is the only Professor that has been shown to catch a Pokémon in the games, catching Pikachu for the protagonist of Pokémon Yellow.
  • Professor Oak was the first non-player character introduced in the Pokémon games.
  • Professor Oak is the only professor who can be battled, though only through a glitch or cheating, and even then, only in Generation I.
  • It has been speculated that Professor Oak became Champion of the Elite Four in his younger years. Agatha states that he was once tough and handsome, and then Oak himself, upon taking the player into the Hall of Fame in Generations I and III, states that only those who have become Champion are allowed into the Hall of Fame. Thus, it is possible that he was once a Champion, because he is allowed to enter the Hall of Fame.
    • This can also be supported by the fact that the default rosters for the unused Professor Oak Trainer class in Generation I have Pokémon whose levels are around that of the Champion's Pokémon.
  • 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 I.
