Professor Samuel Oak (Japanese: オーキド・ユキナリ博士 Dr. Yukinari Okido) 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 games

In Generation I

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.

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.

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 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 ^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'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.

"Hmm? <rival>? Why are you here already? I said for you to come by later… Ah, whatever! Just wait there. Look, <player>! Do you see that ball on the table? It's called a Poké Ball. It holds a Pokémon inside. You may have it! Go on, take it!^Y

"If a wild Pokémon appears, your Pokémon can fight against it!"

"Afterward, go on to the next town."^Y

"You can't get detailed data on Pokémon by just seeing them. You must catch them! Use these to capture 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, though. A healthy Pokémon could escape. You have to be lucky!"^{Wrong template. See Template:Sup/doc.}

Battle

"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. The Trainer that makes the other Trainer's Pokémon faint by lowering their HP to ‌“0,” wins. But rather than talking about it, you'll learn more from experience. Try battling and see for yourself."

"It's important to get know your Pokémon thoroughly. This is a list of your Pokémon, <player>. Open this to check the skills and moves of your Pokémon. You also choose Pokémon here if you want to use an item on one."

• Pokémon is healed via Potion:

"Keep your eyes on your Pokémon's HP. It will faint if the HP drops to “0.”

• If player tries to run:

"No! There's no running away from a Trainer Pokémon battle!"

"Hm! Excellent! If you win, you earn prize money, and your Pokémon will grow! Battle other Trainers and make your Pokémon strong!"

• Battle is lost:

"Hm! How disappointing… If you win, you earn prize money, and your Pokémon will grow. 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. "

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!

• When receiving National Pokédex:

"Ah, now this is excellent! <player>, I have another important favor to ask of you. I need you to listen closely. Recently there have been sightings of many rare Pokémon species. 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. Now, <player> and <rival>! This time, you must really must work towards filling your Pokédexes. I urge you to make them the best and the most complete of all time! Truly, this is a monumentally great undertaking in Pokémon history!

• If talked again before leaving after getting National Pokédex:

"Pokémon around the world wait for you, <player>!

• If talked again before leaving after completing National Pokédex:

Indigo Plateau

• After beating rival:

"<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!"

Hall of Fame

Er-hem! Congratulations, <player>! This floor is the Pokémon Hall of Fame. Pokémon League Champions are honored for their exploits here. Their Pokémon are also recorded in the Hall of Fame. <player>! You have worked hard to become the new League Champion. Congratulations, <player>, you and your Pokémon are Hall of Famers!

"It looks as if you're getting on the right track! I've given one of my Aides a Flash HM. Make sure you go get it!"

• 20-29 Pokémon

"Your Pokédex could use a bit more volume still! Try to catch other species of Pokémon!"

• 30-39 Pokémon

"Good, it's apparent that you're trying hard! I've given one of my Aides an Itemfinder. Be sure to collect it!"

Pokédex evaluation

• Note: Oak evaluates only the National Pokédex.

"Hmhm... You've caught <number> so far... <evaluation quote>"

• Fewer than 40 Pokémon

"They say there are at least 400 species of Pokémon nationwide. If you're planning to catch them all, you'd better be a committed Trainer."

• 40-59 Pokémon

"Hm! Little by little, you're filling the Pokédex with complete data on Pokémon you've gotten. Keep up the good work!"

• 60-89 Pokémon

"Here's a tip on catching Pokémon in the wild. Minimize their HP before you throw your Poké Ball to catch them."

• 90-119 Pokémon

"Remember: If you can't catch them, you can always trade for them. As soon as you trade, the Pokémon's data is added to the Pokédex. That's why you should seek out as many trades as possible."

• 120-149 Pokémon

"Have you visited the Great Marsh? Some Pokémon only appear in places such as that."

• 150-189 Pokémon

"As you know, there are Pokémon that eventually evolve. That's an important thing to consider when you're filling your Pokédex."

• 190-229 Pokémon

"You've proven yourself capable. There's nothing to worry about. Keep catching Pokémon the way you've been doing so far."

• 230-269 Pokémon

"Are you aware that there is more than one style of evolution? There are some Pokémon that evolve by becoming friends with the Trainer."

• 270-309 Pokémon

"Apparently, there are some Pokémon that appear in swarms on occasion. Don't miss out on these massive outbreaks of Pokémon!"

• 310-349 Pokémon

"Amazing! You've already gotten over 300 Pokémon! That's already a major achievement, but I know you're capable of more!"

• 350-379 Pokémon

"Some wild Pokémon only appear during certain times of the day. You'll need to look for Pokémon around the clock."

• 380-409 Pokémon

"I've been getting reports of different Pokémon sightings. By different, I mean Pokémon that aren't native to the Sinnoh region. You should perhaps go back to areas you've already scoured. You may end up seeing Pokémon that weren't there before."

• 410-429 Pokémon

"<player>, have you visited the Pal Park recently? There still may be Pokémon that are rarely seen in Sinnoh."

• 430-449 Pokémon

"Hm! Your Pokédex is getting closer to completion. Have you ever considered a career as a Pokémon professor?"

• 450-459 Pokémon

"Hmm... You've caught quite the impressive collection of Pokémon. You've obviously had to employ many means to seek them all out."

• 460-469 Pokémon

"I can only marvel at the diversity of Pokémon. I'm still very much in awe of them."

• 470-475 Pokémon

"Good, good, you're getting close to completing the Pokédex. I'm looking forward to seeing its completion. When that happens, your views about Pokémon will likely have changed!"

• 476-492 Pokémon (missing a non-event Pokémon*)

"Hmm... You are so very close to completing your Pokédex. Think about what's missing. Recall what you've overlooked. You're so close--please finish the Pokédex!"

• 482-493 Pokémon (all non-event Pokémon)

"<player>! You've finally done it! You've finally completed the National Pokédex! This is better than meeting any exotic Pokémon for the first time! I feel blessed to have become friends with a Trainer like you! Sincerely, I thank you from the bottom of my heart!"

Intro

• If time is from 0:00AM to 3:59AM

"...... Yaaaaaaawn... ... Huh? A guest? At this hour?"

• If time is from 4:00AM to 10:59AM

"...... Yaaaaaaawn... ... Huh? It's already become so bright outside!"

• If time is from 11:00AM to 3:59PM

"...... Yaaaaawn... ... Huh? What?! Is it already that late!? Oh no! I overslept!"

• If time is from 4:00PM to 6:59PM

• If time is from 7:00PM to 11:59PM

"...... 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

• If spoken to while Kyogre^HG/Groudon^SS is in the player's party

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 Orb^HG/Blue Orb^SS will make Groudon^HG/Kyogre^SS appear at the Embedded Tower...

However, according to Mr. Pokémon, Groudon^HG/Kyogre^SS does not show itself to Trainers with golden hearts^HG/shining-silver spirits^SS, but only to those with shining-silver spirits^HG/golden hearts^SS.

It may be difficult for you alone to accomplish this, <player>.

But if you manage to obtain a Groudon^HG/Kyogre^SS 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

• After beating Lance

"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?"

• If the player has obtained no Kanto Gym Badges

"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."

Pokédex evaluation

• Via Pokégear

"Hello, this is Professor Oak... Oh, hello, <player>! So, how's your Pokédex coming along?"

Quit

"Show me your Pokédex again anytime!"

Evaluate

"Hmm, let's see... You've seen <number> Pokémon, and you've caught <number> Pokémon! I see! <evaluation quote> Show me your Pokédex again anytime!"

• 1-9

"Look for Pokémon in grassy areas!"

• 10-19

"Good. I see you understand how to use Poké Balls."

• 20-34

"You're getting good at this. But you have a long way to go."

• 35-49

"Hmm, you're catching Pokémon at a decent pace!"

• 50-64

"You're trying--I can see that. Your Pokédex is coming together."

• 65-79

"You're training them well. You know some Pokémon don't evolve just by battling with others, right?"

• 80-94

"Do you have a Fishing Rod? There are some Pokémon that can only be found by fishing!"

• 95

"Excellent! You seem to be good at collecting things!"

• Johto Pokédex complete

Wow!

That is a complete Johto Pokédex!

Thanks to you, <player>, the Johto Pokédex is complete!

Wow…

You've done an incredible job!

• National Pokédex complete

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!
