Pokémon Crystal Walkthrough 48: The Ninja Clones

Next up is Fuchsia City Gym, and now the previous Gym Leader, Koga is now a member of the Elite Four, his daughter Janine is now the new Gym Leader. In this Gym, there were many people disguised as the Gym Leader, and you'll might be fighting a Trainer if it is not the real one. This Gym isn't that difficult, but with a good Psychic type can make this very easy.
