NamelessShipping

"Red doesn't say much, but he's an amazing guy. Full of love for his Pokémon. Don't tell anyone I said this, but I respect him. There's so much I learned after I lost to him."

- Blue, Pokémon Masters

OriginalShipping is the slash ship between Red and Blue Oak from the Pokémon fandom.

Canon
They are rivals and have opposite personalities. While Red is quiet, humble, and lacks ambition when it comes to popularity, Blue is loud, self-centered, and loves being the center of attention. Despite their differences, they have been friends since childhood and remain so, even after their fights and rivalry during their Pokémon journeys.

Games
Red and Blue are the protagonist and main rival, respectively of the two original Pokémon games released in Japan. In areas outside of Japan, Blue is known as Blue Oak. They are not to be confused with Ash Ketchum and Gary Oak, their anime counterparts.

Childhood friends who grew up together in Pallet Town, they also receive their starter Pokémon at the same time. Whichever Pokémon Red chooses, Blue will choose the one which has a type advantage against it. Throughout Red's journey across Kanto, he encounters Blue numerous times, and they battle only for Red to win. Despite these losses, Blue is determined to become the best trainer. Eventually, his hard work comes to fruition when he beats the Elite Four and becomes the Champion of Kanto. But his victory is short-lived, and Red defeats him to become the Champion.

In Pokémon Gold & Silver, it is learned that after Red won, he left to live on Mt. Silver, and Blue became the Gym Leader of Viridian City.

In Pokémon Sun and Moon, Red and Blue are the leaders of the Battle Tree. They are apparently taking a vacation together in Alola, it should be noted that Blue and Red are now adults in the game and that Red is now taller than Blue and stoic as ever. When you battle the duo, Red is silent the entire battle but Blue seems to be able to interpret whatever he's saying just fine, showing they have a deep understanding of one another.

Pokemon Origins
Blue and Red run into each while they're about to enter Professor Oak's laboratory. They race into the lab, shoving and pushing each other like children. Blue lets Red choose his first Pokémon first, when Red chooses Charmander, Blue chooses Squirtle for the type advantage.

In Lavender Town, Blue gets scared of some ghosts in the Pokémon cemetery and runs down the stairs, running into Red who was about to go up said stairs, Red is concerned upon seeing how terrified his friend is. They end up exploring the rest of the tower and teaming up to defeat Team Rocket together. Red defeats Blue at the Pokémon League, crowning Red the new champion of Kanto. Blue is saddened and starts questioning himself after the loss. Red stands in front of him and whisper's Blue's name, which snaps Blue out of his thoughts and he congratulates Red on becoming the new Pokémon League champion.

The discovery of a new Pokémon "Mewtwo" prompts Blue to go and try to catch it. But he fails and ends up injured after Blastoise landed on him in the battle. Upon hearing this, Red rushes to Blue's room, bursting in and asks if the latter is alright. He calms down after seeing that his best friend is alright and asks Blue about Mewtwo. Blue advises him(likely for Red's safety) to not go and try to capture Mewtwo, since it's too powerful and Red would just end up injured or worse if he tried.

They are seen at the end of the episode eating lunch with Professor Oak and Red's mother.

Fanon
Many fanworks/fiction are about their vacation in Aloha and/or Blue making up to Red for his past treatment of him when they were children. Some popular traits/AU's include Mute!Red, Tsundere!Blue, and Modern AU's. Blue's Eevee and Red's Pikachu are also often if not always featured in fanworks, and are often seen as good friends and fond of their trainers' relationship. It's important to note that Blue Oak is also called Ookido Green in the Japanese translation, but Blue is the official English name Nintendo gave him.

With the release of Pokémon Sun and Moon the ship has gained more shippers because many viewed their teamwork and vacation at Alola as something more than friends, that and the fact Blue was able to tell what Red was thinking without words.

On AO3, it is the most written ship for both characters. It is also the most written in the Pokémon tag.

Theories
Following the release of Pokémon Gold & Silver, fans started to theorize why Red is atop of Mt Silver and solve the mystery to his silence. A popular theory is that Red felt guilty for upsetting Blue after defeating him because he had essentially taken what Blue had always wanted, which was the champion title and his grandfather's attention. Causing him to hide away and detach himself from society and become a hermit.

Meanwhile, at Viridian City, Blue feels guilty that he was the reason Red disappeared for two years, he climbs Mt. Silver to talk to him and perhaps convince him to come down. He reconciles with Red and rekindle their friendship, the possibility of a new romance is up to the fan; but most seems to enjoy having them having a romantic and/or emotional confession atop a snowy mountain in a cave and then having a honeymoon at Alola.

Another theory is that Red had killed Blue's raticate and he found out after defeating Blue at the Indigo League Championships, the guilt of killing his rival's Pokémon could've driven him to hide up at Mt Silver.

The newer name came from the "original" rivals of Pokémon, while the previous name was likely due to fans having a hard time creating a proper ship name because Blue is also known as Green by Japanese fans.
 * They make an appearance at the end of Pokémon Sun & Moon as the leaders of the Battle Tree, taking a vacation together in the Alola region.
 * Red never speaks once in Pokémon Sun & Moon, despite this Blue is unfazed by it and seems to understand what Red's thinking.
 * Their final battle in the game is shown in episode 3 of Pokémon Generations, The Challenger.
 * In the Pokémon Masters, Blue's description describes Red as "his lifelong rival and best friend." Which some have correlated to the Childhood Romance trope.
