Yellow Gym leaders & Elite Four

Pokémon Yellow follows the gameplay in Red/Blue, where you battle your way through 8 gyms, each specializing in a particular type. Following that you take on the Elite Four and the Champion. Most of the gyms have small changes to their line-up, but the Elite Four are the same.

The team of the Champion (aka Gary or Blue) varies depending on which Pokémon his Eevee evolved into. He has a Jolteon if you win your first two battles; a Vaporeon if you lose the first two battles; or a Flareon if you win one and lose one.
