NamelessShipping

 is the slash ship between Red and Green from the Pokémon fandom.

Canon
Red and Green are the protagonist and main rival, respectively of the two original Pokémon games released in Japan. In areas outside of Japan, Green 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, Green will choose the one which has a type advantage against it. Throughout Red's journey across Kanto, he encounters Green numerous times, and they battle only for Red to win. Despite these losses, Green 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 Green became the Gym Leader of Viridian City.
