Vatuka are large and fearsome elemental beings made entirely out of Stone.


It is believed that the Vatuka were created by Energized Protodermis in the Maze of Shadows.[1]

Some Vatuka found their way to Mata Nui. There they mostly resided in Onu-Wahi, but some also lived in Ta-Wahi.[2] Vatuka interacted so infrequently with Matoran that the Matoran questioned if Vatuka even existed.[3] Near the end of the Great War, a Vatuka captured Turaga Whenua. The Vatuka was defeated and Whenua rescued by Takua.[2][1]

The Vatuka on Mata Nui later returned to the Matoran Universe following the Matoran's and Rahi's return after the defeat of Teridax.[citation needed]

After the destruction of the Matoran Universe, many Vatuka immigrated to Spherus Magna.[citation needed]

Abilities and Traits

A red version of the Vatuka

Vatuka appear to be made entirely of rock. They are slightly wider and twice the height of a diminished Matoran of Mata Nui. They are humanoid from the waist up and a pile of stones from the waist down. Though Vatuka are normally gray with red eyes, a red variation with green eyes once lived in Ta-Wahi.[2]

Vatuka are capable of creating blasts of Stone.[2]


  • Though some Matoran tentatively classify the Vatuka as Rahi, some argue against this as they cannot tell if the Vatuka are truly alive.[3]
  • In BIONICLE: The Legend of Mata Nui, Onua would have battled an Earth Elemental called Vatuka-Nui.[4]
  • According to Issue 2 of Nintendo Power Advance, Vatuka are also known as "Rock Monsters".
  • The Vatuka are the same type of creatures what the Energized Protodermis created to fight against the Toa Metru.[5][6]
