Game canon
Red sets off on a journey with his rival blue-oak. He ends up bringing down Team Rocket and becomes the Kanto champion while filling out Professor Oak's dream of completing the Pokédex.

In the Johto games (Gold, Silver, Crystal, HeartGold, and SoulSilver) which takes place two years after, he leaves his position to train on Mt. Silver, where the protagonist
Ethan, kris-game, or
