Regeneration#
A central feature of the Elemental BeastsElemental BeastsThe Lava, Storm, and Quake armies summoned by Umarak the Destroyer from Shadow Traps and the environment of Okoto, raised to distract the Toa while he gathered the fragments of Makuta's Mask of Ultimate Power. was the capacity for bodily regeneration. If a beast's body was destroyed in combat, it could reform around its crystalline mask, allowing the creature to return to active engagement. Permanent destruction required the destruction of the mask itself.
Operational role#

Frequently asked questions
- What are the Elemental Beasts?
- The Elemental Beasts were armies of humanoid-beast Rahi deployed on Okoto by Umarak the Destroyer. They existed in three variants, each grown from a single mutated Shadow Trap element and tasked with engaging the Toa while Umarak recovered the fragments of Makuta's Forbidden Mask.
- What are the three variants of Elemental Beast?
- The three variants were the Lava Beast, the Storm Beast, and the Quake Beast. The Lava Beast was made primarily from mutated Fire Shadow Traps, the Storm Beast from mutated Water Shadow Traps, and the Quake Beast from mutated Earth Shadow Traps. The name of each reflected its combat profile rather than a fusion of multiple elements.
- How were the Elemental Beasts created?
- They were generated from Shadow Traps and ambient material drawn from the Okoto environment, shaped by powers that Makuta had granted Umarak following his reforging as the Destroyer. The seed material consisted of Shadow Traps originally tied to specific Elemental Creatures and held in reserve across the island, and Umarak drew on Earth, Water, and Fire Traps to spawn his three variants.
- How could the Elemental Beasts be destroyed?
- If a beast's body was destroyed in combat, it could reform around its crystalline mask and return to active engagement. Permanent destruction required the destruction of the mask itself. All known Elemental Beasts were destroyed by the conclusion of the Toa of Okoto's campaign against Umarak and Makuta.
- Why did the Elemental Beasts resemble the Elemental Creatures?
- The Beasts incorporated physical features drawn from Okoto's six original Elemental Creatures. The Lava Beast bore horns reminiscent of Uxar and wings and talons resembling Ikir's, the Storm Beast featured claws like Melum's and a tail like Akida's, and the Quake Beast displayed crystal claws comparable to Terak's and green blade pieces matching Ketar's. The result was antagonist creatures that visually echoed the island's natural guardians while functioning in opposition to them.
