Olmakla

The Kanohi Olmakla, or The Mask of Dimensional Gates Recharged, was Raanu-G's mask after being hit by Maka-Taka. It allows him to travel to other dimensions, and take stuff back to his own. He does this with Mata Nui's mask in: "The Dimension Chronicles". However, his limitation is: he must, if he takes something out of a dimension, put it back doing the exact same thing at the exact same time. Also, if it is a living creature or being, he must completley brainsweep it. Brainsweeping is another thing his mask can do.
