Brolokis is a boss fought in Baten Kaitos: Eternal Wings and the Lost Ocean. It is a species of monster fish (related to the Thunderfish) that is sometimes referred to as the "Master of the River" or "Lord of the Greater Celestial River." It hasn't been seen for over a hundred years, and was thought to have been endangered. However, it appears that many still exist. Brolokis is fought at the end of the Greater Celestial River and serves as the boss to Gibari's Quest.
