Blue Oak (Japanese: オーキド・グリーン, Hepburn: Ookido Guriin, trans. lit. "Green Orchid"), more commonly known as Blue, is the player's rival and eventual Pokémon Champion in the Generation I games, Pokémon Red Version and Pokémon Blue Version. He then becomes a Gym Leader for Viridian City since Generation II after losing his League title to Red, replacing Giovanni. Blue himself is unique as a Gym Leader, because he has no set type for his Gym, and instead uses a variety of Pokémon in a similar manner to the other Champions. He gives the Earth Badge to Trainers who are able to defeat him. He is known as Green in Japan.

His necklace is changed to have a small gray oval on it instead of being a yin and yang necklace. He also has wood colored hair, and sand brown eyes.
Personality[]
In the original Generation I games, Blue is a self-absorbed, rude, snarky and overly competitive rival to the player. He will often insult the player, and is not a good sport when the player defeats him in a battle. With each defeat, he insists that the player was lesser and weaker than he was, denies the fact that he is not as skilled, and bids farewell in a disrespectful manner, often saying "Smell ya later!" as he walks away. In spite of this, he apparently does consider the player his friend, frequently calling them “pal”.
However, in Pokémon HeartGold Version and Pokémon SoulSilver Version, the Generation IV remakes of Pokémon Gold Version and Pokémon Silver Version, Blue is a more mature and much kinder person, and is shown to gracefully accept defeat when the player challenges and beats him at the Viridian Gym. He is also shown to be passionate and respectful in Generation V, and likes to battle a challenger, no matter who they are.
Biography[]
Games[]
Pokémon Red Version and Pokémon Blue Version[]
In the Japanese Pocket Monsters Red and Pocket Monsters Green, and the international Pokémon Red Version and Pokémon Blue Version, the player first meets him in Professor Oak's Lab, where he gives both a First partner Pokémon.
Despite the player first meeting Blue at the games' beginning, the characters have evidently known each other for a long time, as stated by Professor Oak. As with every game, whichever Pokémon the player chooses, the rival (Blue) will choose the type that is effective against it (except in Generation VII; e.g. player chooses Bulbasaur (Grass), rival will then choose Charmander (Fre).
Later, after receiving the Pokédex, Blue will set out to find every Pokémon and be one step ahead of the player. As the player progresses through the game, he/she will encounter their rival in several locations and have to battle them every time.
Toward the end, after receiving all eight Gym Badges and defeating all of the Elite Four, it is revealed that Blue has already defeated the Elite Four and has become the Pokémon Champion. Challenging him, the player will battle Blue for the title, and when defeated, Professor Oak will come in and induct the player into the Hall of Fame.
Blue's appearance in the original games changes twice from the original appearance, throughout the game. The second appearance is similar to the first, with the addition of a backpack and a Poké Ball. The third (champion appearance), looks almost completely different, with an all new attire, and different hair.
Pokémon Yellow Special Pikachu Edition[]
In Pokémon Yellow Special Pikachu Edition, he is identical to that of the initial Red and Blue version. In this game however, his appearance is more similar to Gary's appearance from Pokémon the Series. Also, instead of choosing the opposite Pokémon based on type advantage, Blue chooses Eevee as his Starter Pokémon, while the player must take Pikachu. Blue shoves the player out of the way and claims Eevee before the player can obtain it. Prof. Oak had intended to give the player this Eevee, but the newly-capured Pikachu becomes fated to be with the protagonist. The first two battles with Blue are the deciding factor for what his Eevee will evolve into. It is decided on whether the player wins or loses the battles in Professor Oak's lab and on Route 22, or simply skips the latter area. If the player loses the first Battle with Blue, Eevee will evolve into Vaporeon. If the player wins the first battle and then skips the optional one, it will evolve into Flareon. And if the player defeats Blue both times, it will evolve into Jolteon.
In all Generation I games, Blue's appearance also alters twice after a while, though his Champion appearance in the Red and Blue games is a little more dramatic than in Yellow. The battle sprite is simply in new poses each time. He is still the Champion until you defeat him in the final battle.
Pokémon Gold Version and Pokémon Silver Version[]
In Pokémon Gold Version and Pokémon Silver Version, he is far less involved when compare to the previous, as Silver is that games' rival instead. After the disappearance of Giovanni, the former Head of Team Rocket and Viridian Gym Leader, Blue takes over the Gym. Unfortunately for trainers and much like Giovanni himself, he is never usually at the Gym, making it difficult to battle there. Unlike any other known Gym Leaders, Blue uses a variety of types in his Pokémon team.
Pokémon FireRed Version and Pokémon LeafGreen Version[]
In Pokémon FireRed Version and Pokémon LeafGreen Version, his role is exactly the same as in the original Red and Blue versions. The only slight difference however is that his appearance does not change throughout the games.
Pokémon HeartGold Version and Pokémon SoulSilver Version[]
In Pokémon HeartGold Version and Pokémon SoulSilver Version, much like in the original namesake Gold and Silver games, he is far less involved compared to FireRed and LeafGreen and Blue becomes the leader of the Viridian Gym. He still uses a variety of Pokémon. In these games, he is supposedly the strongest in Kanto as opposed to Red.
Pokémon Black Version 2 and Pokémon White Version 2[]
In Pokémon Black Version 2 and Pokémon White Version 2, his role is very minor. He appears in the Pokémon World Tournament as Kanto's Champion and where he is matched up against the player to battle in the Champions Tournament.
Pokémon X and Pokémon Y[]
Although not making an appearance in Pokémon X and Pokémon Y, he is mentioned by a lady in Lumiose City's Pokémon Center that he had studied in Kalos before.
Pokémon Sun and Pokémon Moon[]
In Pokémon Sun and Pokémon Moon When the player arrives at the Battle Tree for the first time, they can choose either Blue or Red to be their opponent for a match. He will be impressed by their abilities after he loses the match. They can later challenge him at the Battle Tree. Most people in the community oddly believe this to be Red and Blue's honeymoon, but this has never been explicitly stated by Nintendo, Game Freak, or The Pokémon Company.
Pokémon: Let's Go, Pikachu! and Pokémon: Let's Go, Eevee![]
In Pokémon: Let's Go, Pikachu! and Pokémon: Let's Go, Eevee!, Blue is not the player's rival unlike in Pokémon Yellow Special Pikachu Edition, as Trace takes his role. He appears various times in the game, but the player's first encounter with him is after defeating Brock. The player encounters him again in Silph Co in which he will be battled. He is in Professor Oak's lab to give you the ability to Mega Evolve. He can be battled on Viridian City Gym after defeating the Champion (Trace) the first time, once per day.

Trivia[]
- Blue is the first rival and Pokemon Champion of the Pokémon franchise.
- He has appeared in at least two of the main series games in every generation so far, with the exception of VI and VIII. He is mentioned in Pokémon X and Pokémon Y, however.
- Unlike most other rivals, Blue doesn't always choose a Pokémon with type advantage: in Pokémon Yellow Special Pikachu Edition, he has to settle for an Eevee, which can potentially evolve in the three evolution forms available at the time (Vaporeon, Flareon, or Jolteon).
- He is the first Champion and rival who ends up being a Gym Leader in a later Generation.
- In Pokémon X and Pokémon Y, a lady sitting at the table in the Pokémon Center near Magneta Plaza in Lumiose City says that Blue has come to visit Kalos to study abroad a while back.
- In the original Generation I games, as well as Pokémon Origins, according to his grandfather Professor Oak, the reason why Blue lost his Champion title to Red is because he had forgotten to treat his Pokémon with trust and love, although Blue himself claims he had never made any mistakes raising his Pokémon.
- Since the player reaches him only after he became Kanto's Champion, this would also make Blue by far the shortest reigning one in the franchise.
- Blue's motive for facing the player in Silph Co. it is to see if the player would be able to drive Team Rocket out of Saffron City. This means that he indirectly helped the player character, though he only did it so that he could get into the Saffron City Gym and defeat Sabrina.
- Blue is the only Gym Leader who specializes in multiple Pokémon types.
- As seen in Pokémon Yellow Special Pikachu Edition, Blue is the only Pokémon Champion to use an Eeveelution. This would repeat for Trace in Pokémon: Let's Go, Pikachu! (though he only uses Jolteon).
- Although Red, as an NPC, often has the role of a Champion and uses an Espeon in Generation II, he is technically a player character.
- Blue has owned two "illegal" Pokémon:
- In Pokémon Red Version and Pokémon Blue Version, if his team includes Gyarados, said Gyarados knows both Dragon Rage and Hydro Pump at level 22 (if the player chose Bulbasaur) or level 23 (Squirtle), the latter of which the Pokémon cannot legally learn until level 43. While it is possible for Gyarados to be taught Dragon Rage early via TM (when it naturally learns the move at level 25), no such explanation can be made for it knowing Hydro Pump early.
- In Pokémon FireRed Version and Pokémon LeafGreen Version, his Pidgeotto is first seen at level 17, one lower level than Pidgey is supposed to evolve at.
