This is a hack of Pokémon Fire Red that sees Blue’s perspective as he battles Red to become the Pokémon League Champion.
This version (loosely) follows Lockstin & Gnoggin’s video that dealt with the theory of if Blue joined Team Rocket.
Depending on what starter is chosen, your rival will either have the team they have in the game, in the Pokémon Adventures Manga, or the Pokémon Origins adaptation.
Enjoy!
