Bryyo Leviathan Core

The Bryyo Leviathan Core is a room in Metroid Prime 3: Corruption which is nearly spherical in appearance and is the battlegrounds for the fight with an Ancient Reptilicus War Golem named Mogenar which appears to be receiving energy from the core of the Bryyo Leviathan Seed before the fight between itself and Samus commences. There are three inaccessible gaping holes in the Bryyo Leviathan Core: one on the Western wall, one on the Northern wall, and one on the Eastern wall, each pulsating in a rhythmic manner.
