The Lava Beasts, along with the Quake Beasts and Storm Beasts, were unleashed by Umarak on the orders of Makuta to keep the Toa occupied while Umarak searched for the pieces of Makuta's Mask of Ultimate Power. They were created by Shadow Traps being fused with the power of the elements and unleashed against the City of the Mask Makers, where they fought the Toa and Elemental Creatures. However, after the initial wave was beaten back by the Toa, it fell to the Creatures and the native Okotans to continue the battle while the Toa and Ekimu sought out Umarak to halt Makuta's plans. They later fought several of the Elemental Beasts on their way, and Gali saw others while trapped in the Shadow Realm prior to Makuta's ultimate defeat.



  • Instructions were released to combine the three Beasts and Umarak the Destroyer into a larger model; this had no role in the storyline.
