Professor Oak

Professor Samuel Oak (Japanese: オーキド・ユキナリ博士 Dr. Yukinari Ōkido) 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 Generation I


Professor Oak works in his Laboratory in Pallet Town with his aides. He gave and  their Starter Pokémon in, , ,. 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.

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. is allowed to choose one in order to begin his journey. His grandson,, the undefined's rival, then picks the Pokémon whose type has an advantage against their own.

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

This 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.

Unused teams
In the Generation I games, there is unused 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 level 66, level 67 , level 68 , level 70 and one of the Kanto s 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 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.

The only known ways to battle Oak are by performing the with a  stat of 226 or by performing the old man glitch with  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 is lowered by 4, 5, or 6 stages (each will yield a different one of the three teams).

The rest is as follows
 * "Sorry to keep you waiting! Welcome to the world of Pokémon! My name is Professor Oak. But everyone calls me the Pokémon Professor. Before we go any further, I'd like to tell you a few things you should know about this world! This world is widely inhabited by creatures known as Pokémon. We humans live alongside Pokémon as friends. At times we play together, and at other times we work together. Some people use their Pokémon to battle and develop closer bonds with them. Now, why don't you tell me a little bit about yourself? Are you a boy? Or are you a girl? Won't you please tell me?"
 * "So, you're a boy/girl then?"

What's this? A rare Pokémon! I see! You must be helping Professor Elm's research! I think I understand why Professor Elm gave you that Pokémon. You will treat your Pokémon with love and care, it seems. ...Ah! You seem to be dependable. How would you like to help me out? See? This is the latest version of the Pokédex. It automatically records data on Pokémon you've seen or caught. It's a high-tech encyclopedia! I'd like you to have it. Go meet many kinds of Pokémon and complete that Pokédex! But I've stayed too long. I have to get to Goldenrod for my usual radio show., I have a feeling that is not the last time we'll meet... Let's exchange numbers just to be on the safe side."

Pallet Town
 * Choosing Kanto Starter
 * If spoken to again after having been offered a Kanto starter, but before choosing one
 * "You don't see them very often in Kanto. Choose one and it'll be yours! ...Go ahead!"


 * When checking the Charmander Poké Ball
 * "So, you're claiming the Fire Pokémon <sc>Charmander</sc>?"


 * When checking the Squirtle Poké Ball
 * "So, you've decided on the Water Pokémon <sc>Squirtle</sc>?"


 * When checking the Bulbasaur Poké Ball
 * "So, you want to go with the Grass Pokémon <sc>Bulbasaur</sc>?"


 * When declining any starter
 * "No need to hurry. Take your time."


 * Upon choosing starter
 * "This Pokémon is really energetic!"


 * After starter has been added to party
 * "If a wild Pokémon appears, your Pokémon can battle it. With it at your side, you should be able to reach the next town... What am I saying? You already know all this! Hahaha!"


 * Embedded Tower Legendaries
 * If spoken to while / is in the player's party
 * Oh, ! What brought you here?
 * The legendary Pokémon that appear in the Hoenn myth?
 * You must be talking about Kyogre and Groudon!
 * The Embedded Tower is probably the ruins that has something to do with the Hoenn myth. If so, the other one must be around.
 * Kyogre and Groudon are said to have shaped the seas and lands!
 * Where those two are, the other Pokémon is said to appear as well... All this is quite possible!
 * ''It's not hard to imagine that the Red Orb/Blue Orb will make Groudon/Kyogre appear at the Embedded Tower...
 * However, according to Mr. Pokémon, Groudon/Kyogre does not show itself to Trainers with golden hearts/shining-silver spirits, but only to those with shining-silver spirits/golden hearts.
 * It may be difficult for you alone to accomplish this, .
 * But if you manage to obtain a Groudon/Kyogre that came from the Embedded Tower, please do come and show me both legendary Pokémon!
 * I will then share with you the rest of the Hoenn myth!


 * If spoken to while both Groudon and Kyogre from the Embedded Tower are in the player's party
 * You did it, ! You caught both Kyogre and Groudon! OK! I would like to entrust this to you!
 * ''It resembles the Orb you received from Mr. Pokémon, doesn't it?'
 * It is called the Jade Orb. It has something to do with .
 * Legend has it that the battle between Groudon and Kyogre shaped the lands and seas of Hoenn.
 * Volcanic eruptions and giant waves are said to have completely changed the shape of the land there.
 * But then Rayquaza came down to halt the battle.
 * It is a Pokémon that rules the skies!
 * If the Embedded Tower is related to Kyogre and Groudon, then going there with that Jade Orb will surely make something happen.


 * If spoken to while Rayquaza is in the player's party
 * You have successfully caught Rayquaza!
 * The strong power of the Jade Orb must have attracted Rayquaza there!
 * Pokémon are sometimes greatly attracted by certain Orbs and Stones. No one knows why.
 * Perhaps memories from ancient times... when this planet was born... and Pokémon, also... are making Pokémon behave that way.

Indigo Plateau

 * If the player has started to collect Kanto Gym Badges
 * "Ah, you're collecting Kanto Gym Badges. I imagine that it's hard, but the experience will surely help you. Come see me when you get them all. I'll have a gift for you. Keep it up, ! So how's your Pokédex coming along?"
