Buna is a member of the Aravea Elite Four in Pokemon Genesis and a user of Pokemon from the Bug Egg Group. It is often a misconception that she uses Bug-Type Pokemon, when she really uses Pokemon from the Egg Group.
Little is known about Buna's early life, but Graham states in the game that she was once a family friend and a Bug Catcher. It is unknown if she ever went to the Bug League and became a Bug Maniac. However, Graham rarely speaks with her anymore.
