Tubaloid

Tubaloid (チューバロイド Chūbaroido?): Tubaloid, designated O-10, is created when the Hoeru (吠える?, "to howl") Metavirus infects one of two tubas for the purpose of marking the Go-Busters with his apparently weak sound wave as phase one of Enter's master plan. Managing to get only Red Buster and Blue Buster, Tubaloid is destroyed by the Go-Busters.
