Anime[]

Aya is a ninja who specializes in using Poison-type Pokémon. She is the sister of Koga and has studied under him since she was very young.

Pokémon the Series: The Beginning[]

Aya encountered Ash, Misty, and Brock in the Fuchsia City Gym. Aya challenged Ash to a battle with her Venonat and Ash agreed—sending out Bulbasaur. He won the match easily with his Bulbasaur's Leech Seed. After the battle ended, her older brother Koga appeared.

Pokémon the Series: Gold and Silver[]

Aya was training at the Pokémon Jujitsu Academy, learning Pokémon Jujitsu. She and her Venonat were unable to master it; she even faced Ash and his Bulbasaur in a rematch and lost. But after an encounter with Team Rocket, she was able to bring out her Venonat's full potential and defeat them. She then returned to the dojo to fully master Pokémon Jujitsu.
