The Brotherhood of Underworld Monsters is a group from the Legend of Zelda animated series. It is an organization created by Moblins that grew sick of Ganon's failed attempts at obtaining the Triforce. Using a magic rod, the Moblins trap Ganon in a bubble and drop him into the Endless Pit. The Brotherhood then recruits monsters, including Octoroks, River Zoras, and Stalfos. After recruiting monsters, they then attack Hyrule Castle. The Brotherhood of Underworld Monsters poses no real threat to Link and Princess Zelda; they are very disorganized and end up defeating themselves from within since they do not have Ganon as their leader.
