Blue

, more commonly known as Blue, is the player's rival in the Generation I games, Pokémon Red Version and Pokémon Blue Version. Blue is unique as a Gym Leader, because he has no set type for his Gym, and instead uses a variety of Pokémon. He gives the Earth Badge to Trainers who are able to defeat him.

His necklace has changes to have a small gray oval on it instead of being a ying and yang necklace. He also has wood colored hair, and sand brown eyes.
==Personality==
In the 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 HeartGold and SoulSilver, 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===
As previously noted, Blue serves as the player's Rival in the Generation I and Generation III remake games. In Gold, Silver, Crystal, HeartGold and SoulSilver (Generations II and IV), Blue has a less involved role, as the Viridian City Gym Leader.
====Red, Green and Blue====
In Red, Blue and Green, 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 start, 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 (Fire).
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.
====Yellow====
In Pokémon Yellow Special Pikachu Edition, he is similar to that of the Red and Blue version. In this game however, his appearance is more similar to Gary's appearance from the anime series. Also, instead of choosing the opposite Pokémon, Blue chooses Eevee as it is the only one, while the player must take Pikachu.
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 optionally one, it will evolve into Flareon. And if the player defeats Blue both times, it will evolve into Jolteon.
In these games, Blue's appearance also alters twice after a while, though not as dramatic as the champion appearance in the Red and Blue games. The battle sprite simply are in new poses each time. He is still the Champion until you defeat him.
====Gold and Silver====
In Pokémon Gold Version and Pokémon Silver Version, he is far less involved when compare to the previous. After the disappearance of Giovanni, the former Head of Team Rocket and Viridian Gym Leader, Blue takes over the Gym. Unfortunately for trainers, he is never usually at the Gym, making it hard to battle there. Unlike any other known Gym Leaders, Blue uses a variety of types in his Pokémon team.
====Crystal====
His role in Crystal is the same as it is in Gold and Silver.
====FireRed and LeafGreen====
In Pokémon FireRed Version and Pokémon LeafGreen Version, he has exactly the same as in Red and Blue. The only slight difference however is that his appearance does not change throughout the games.
====HeartGold and SoulSilver====
In Pokémon HeartGold and SoulSilver Version, he is far less involved compared to FireRed and LeafGreen. Much similar to its namesakes Gold and Silver, 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.
====Black 2 and White 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.
====X and Y====
Although not making an appearance, he is mentioned by a lady in Lumiose City's Pokémon Center that he had studied in Kalos before.
====Sun and 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 believe this to be Red and Blue's honeymoon, but this has never been explicitly stated by Nintendo, Game Freak, or the Pokémon Company.
====Ultra Sun and Ultra Moon====
====Let's Go, Pikachu! and Let's Go, Eevee!====
Blue appears various times in the game, but your first encounter with him is after defeating Brock. You encounter him in Silph Co in which you battle him. 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 the first time, once per day.

==Trivia==
*He has appeared in at least two of the main series games in every generation, with the exception of VI and VIII. He is mentioned in X and Y, however.
*Blue is the youngest Champion.
*Blue doesn't always choose a Pokémon with type advantage: in Yellow, he has to settle for an Eevee.
*He is the first Champion who ends up being a Gym Leader in 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.
*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 Blue could get into Saffron's Gym and defeat Sabrina.
*Blue is the only Gym Leader who specializes in multiple Pokémon types.
*Blue has owned two illegal Pokémon:
**In Red and Blue, 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 FireRed and LeafGreen, his Pidgeotto is first seen at level 17, one lower level than Pidgey is supposed to evolve at.
