From Bulbapedia, the community-driven Pokémon encyclopedia.
Aira is a member of Team Great Rocket from Template:Card GB 2. He's one of the Trainers at the GR Water Fort.
His deck, Bench Call Deck (Japanese: ベンチよびだしデッキ), focuses on Pokémon. In all duels against him, no more than three Benched Pokémon are allowed at any time.
When defeated, he gives out one Team Rocket's Ambition booster pack. Also, when defeated for the first time, he lets the player advance to the next room, allowing the player to reach Kanoko, the Fort Leader of GR Water Fort.
