The Fuchsia Gym (Japanese: セキチクジムSekichiku Gym) is the official gym of Fuchsia City. It is based on Template:Type2Pokémon. In Generations I and III, the Gym Leader is Koga. However, by Generation II, the Gym Leader's duties had been taken up by Koga's daughter, Janine. Trainers who are victorious at this gym may receive the Soul Badge.
The Fuchsia Gym can be difficult to navigate, as both Koga and Janine have installed invisible walls. Janine has added a further step to the puzzle, as the other trainers in the gym all look like her.
A field based on the gym also appears in Pokémon Stadium's Gym Leader Castle.
Trainers with a telephone symbol by their names will give their Pokégear number to the player, and may call or be called for a rematch with higher-level Pokémon.
Fuchsia Gym appeared in only one episode of the anime. Its appearance is based on an old-fashioned Japanese mansion. It is located in a forest outside of the main city. It is filled with booby traps, most notably invisible walls and a horde of explosive Voltorb. Battles take place either inside the mansion or in the courtyard outside.
In The Ninja Poké Showdown, Ash sought out the Fuchsia Gym in order to defeat Koga for his sixth badge. Before he found Koga, he found what appeared to be a stray Venonat. After following it into the gym and finding several Voltorb, Ash and co. encountered Aya, who revealed the Venonat was hers. After defeating her, Koga, Aya's brother, appeared and accepted Ash's challenge.
The battle was interrupted by Team Rocket, who wanted to steal all of the gym's Pokémon. Thanks to Psyduck, and Koga's use of a slanted room, the trio was sent blasting off. Ash and Koga continued their battle outside. With the help of Charmander, Ash defeated Koga and earned his Soul Badge.
