The Gym Leaders are the same as in the original Pokémon Red and Blue games. However, their teams have been altered to include fused Pokémon. There are also 8 additional Gym Leaders from the Johto region that weren't in the original games. In gym battles, you are only allowed to use as many Pokémon as the Gym Leader.
