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.

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 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 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 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).







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's name> 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.

"Oh, for Pete's sake… So pushy, as always. <player>. You've never had a Pokémon battle before, have you? A Pokémon battle is when Trainers pit their Pokémon against each other.

But if you lose, <player>, you end up paying prize money… However, since you had no warning this time, I'll pay for you. But things won't be this way once you step outside these doors. That's why you must strengthen your Pokémon by battling wild Pokémon. "

It's a high-tech encyclopedia! <player> and <rival>. Take these with you. You can't get detailed data on Pokémon by just seeing them. You must catch them to obtain complete data. So, here are some tools for catching wild Pokémon. When a wild Pokémon appears, it's fair game. Just throw a Poké Ball at it and try to catch it! This won't always work, however. A healthy Pokémon can escape. You have to be lucky! To make a complete guide on all the Pokémon in the world… That was my dream! But, I'm too old! I can't get the job done. So, I want you two to fulfill my dream for me. Get moving, you two. This is a great undertaking in Pokémon history!

I'm talking about Pokémon that have never been seen in Kanto. I would love to go see things for myself, but I'm much too old. Since I can't do it, <player>, I'd like you to go in my place.
"I know, I know. Of course I need your help, too. Now, I need to see both your Pokédexes. … … … … … … … … … … … … …And that's done! Now these units can record data on a lot more Pokémon.

"<player>! So, you've won! Sincerely, congratulations! You're the new Pokémon League Champion! You've grown up so much since you first left with <starter> to work on the Pokédex. <player>, you have come of age! <rival>… I'm disappointed in you. I came when I heard you'd beaten the Elite Four. But, when I got here, you had already lost! <rival>, do you understand why you lost? You have forgotten to treat your Pokémon with love and trust. Without them, you will never become a Champ again! <player>. You understand that your victory was not just your own doing. The bond you share with your Pokémon is marvelous. <player>! Come with me!"

"...... Hmm... Interesting... ... Huh? Oh! Excuse me, sorry! I was just reading this book here."

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?"
"Please tell me your name."
"Your name is <name>?"
"<Player>! Are you ready? Your very own tale of grand adventure is about to unfold. Fun experiences, difficult experiences, there's so much waiting for you! Dreams! Adventure! Let's go to the world of Pokémon! I'll see you later!"
Mr. Pokémon's house
"And with that... I'm Professor Oak, a Pokémon researcher! So you're <player>! I was just visiting my friend Mr. Pokémon. I heard you were running an errand for Professor Elm, so I waited here. Oh! 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. <player>, 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 Charmander?"
  • When checking the Squirtle Poké Ball
"So, you've decided on the Water Pokémon Squirtle?"
  • When checking the Bulbasaur Poké Ball
"So, you want to go with the Grass Pokémon Bulbasaur?"
  • 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
Oh, <player>! 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 OrbHG/Blue OrbSS will make GroudonHG/KyogreSS appear at the Embedded Tower...
However, according to Mr. Pokémon, GroudonHG/KyogreSS does not show itself to Trainers with golden heartsHG/shining-silver spiritsSS, but only to those with shining-silver spiritsHG/golden heartsSS.
It may be difficult for you alone to accomplish this, <player>.
But if you manage to obtain a GroudonHG/KyogreSS 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, <player>! 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 Rayquaza.
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
"Ah, <player>! It's been a long while. You certainly look more impressive. Your conquest of the League is just fantastic! Your dedication, love, and trust for your Pokémon made this happen. Your Pokémon were outstanding, too. Because they believed in you as a Trainer, you persevered. Congratulations, <player>!"
Professor Oak's Laboratory
  • Upon first meeting
"Ah, <player>! It's good of you to come all this way to Kanto. What do you think of the Trainers out here? Pretty tough, huh?"
"Hmm? You're not collecting Kanto Gym Badges? The Gym Leaders in Kanto are as tough as any you battled in Johto. I recommend that you challenge them. So, how's your Pokédex coming along?"
  • 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, <player>! So how's your Pokédex coming along?"
  • Via Pokégear while inside Professor Oak's Laboratory
"Hello, this is Professor Oak... Hmm... It's strange. I know your voice, <player>, but somehow hearing it over the phone makes it sound so different."

  • 170-184
"When you trade Pokémon, you can also trade information. Your friends can really help you!"

"Are you trading your Pokémon? It's tough to do this alone!"
  • 200-214
"Wow! You've reached 200! Your Pokédex is looking great!"
  • 215-229
"You've found so many Pokémon! You've really helped my studies!"
  • 230-244
"Magnificent! You have the ability to become a great Pokémon Professor someday!"
  • 245-255 (at least one non-event Pokémon missing)
"Your Pokédex is amazing! You're ready to turn professional!"
  • Johto Pokedex is complete (254-256; all non-event Pokémon caught)
Wow!
That is a complete Johto Pokédex!
Thanks to you, <player>, the Johto Pokédex is complete!
Wow…
You've done an incredible job!
  • If Johto Pokédex is already complete (pre-National)*
"Really, you've surprised me! But just as I expected, you've completed the Johto Pokédex. I am so grateful! If you've got much determination, then even more exciting adventures await you in the world of Pokémon!"
National Pokédex
  • 0-100
"The goal may be far away, but don't give up yet! Keep going!"
  • 101-150
"Don't forget, some Pokémon only appear at certain times of the day!"
  • 151-200
"If you break rocks, some Pokémon that were hiding there might come jumping out!"
  • 201-250
"That's wonderful you've been able to gather this many Pokémon! The path ahead is long. Keep up the great work!"
  • 251-300
"If you Headbutt a tree, sometimes a Pokémon might fall out!"
  • 301-350
"A lot of Pokémon not found in the Johto region like to congregate at the Safari Zone."
  • 351-400
"Music on the radio might also entice Pokémon to leap out!"
  • 401-435
"Wow, you've gotten so far...! I'm actually a little surprised!"
  • 436-465
"This is a critical moment! You can't become discouraged!"
  • 466-475
"Just a little more! I've got high expectations for you!"
  • 476-492 (at least one non-event Pokémon is missing*)
"I have never before in all my years seen such an incredible Trainer!"
  • National Pokédex complete (484-493; all non-event Pokémon caught)
Excellent!
That is an amazing National Pokédex!
Wow…
You've lived up to my expectations wonderfully!
No, you've exceeded them, <player>. You've become an amazing Trainer!
Thank you, <player>!
  • After completing both the Johto and National Pokédex*
You have truly surprised me!
You've more than exceeded my expectations. You've gone far past them in completing the National Pokédex!
I'm speechless…!
Because of this, the world of Pokémon and Trainers is more vast, deeper, and more abundant!
Now there will be no end to Pokémon research!

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.

Trivia

  • Professor Oak has appeared in the most generations of any Pokémon Professor, appearing in Generation I and their Generation III remakes as the regional professor and making cameo appearances in Generation II and Generation IV.
  • 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.
