Biography

Games

Red, Green, Blue & Yellow

Koga first appears in the games as the Fuchsia City Gym Leader. His gym was constructed with an array of invisible walls, fashioned into a maze. This forces the player to walk through the maze fighting Gym members, with the destination in the middle where Koga awaits.

Gold, Silver & Crystal

Later, in the Generation II games, Koga has been promoted to Elite Four status. With the absence of a Gym Leader at Fuchsia Gym, Koga leaves the Gym under his daughter's care, Janine, making her the new Gym Leader.

FireRed & LeafGreen

In the remakes of the original games, Pokémon FireRed and LeafGreen, Koga is once again a Gym Leader, as it takes place during the same time period. The only difference is the level of his Weezing, and his updated appearance.

Trivia

• Koga's name derives from Kōga-ryū, a school of ninjutsu that focused on, among other techniques, poisoning. Kyō, his Japanese name, may come from 凶 (kyō, misfortune), 戮 (kyō, kill), or 杏 (kyō, apricot, as apricot seeds are poisonous).
