The Unity Mask of Stone was a Mask of Power worn by the Master Pohatu. Ekimu created it to replace the Golden Mask of Stone after its damage by Kulta (possibly creating it from the damaged previous mask). This mask could allow Pohatu to commune with the Creature of Stone, but not actually unite with it. Its control over the element of Stone is likely at a similar level to the Golden Mask of Stone. It was later replaced by the Golden Unity Mask of Stone.
