Fwahahaha! A mere child like you dares to challenge me? That very idea makes me shiver with mirth! Very well, I shall show you true terror as a ninja master! Opponents can't lay a hand on me, as poison brings their steady doom. Despair as you feel the creeping horror of Poison-type Pokémon!

–Koga, Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!

Koga served as the Gym Leader at the Fuchsia City Gym. Two years later, during the Generation II games, Koga also became a member of the Elite Four and his daughter, Janine took over his gym and used Poison-type Pokémon as well.

He specializes in Poison-type Pokémon, and as a Gym Leader gave out the Soul Badge for Trainers that could defeat him.

Let's Go, Pikachu! and Let's Go, Eevee!

Koga has black, spikey hair and bushy eyebrows. He is always wearing a red scarf over his mouth and nose. He has a purple ninja-style outfit, with black finger gloves and boots. He has a white belt around his waist.

Personality

Koga shows himself as an intimidating foe, using Poison-type Pokémon, whose moves poison or lull the opponent to sleep.

Etymology

The name Koga originates from Kōga-ryū, a school of ninjutsu that focused on, among other techniques, poisoning.

His Japanese name, Kyō, may originate from from 凶 (kyō, misfortune), 戮 (kyō, kill), or 杏 (kyō, apricot, as apricot seeds are poisonous).

Biography

Games

Red, Green and Blue

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.

Yellow

His role in Yellow is the same as it is in Red, Green and Blue.

Gold and Silver

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.

Crystal

His role in Crystal is the same as it is in Gold and Silver.

FireRed and 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.
