Makuta

Makuta was a powerful being, one of the Mask Makers, and the forger of the Mask of Ultimate Power. He is the brother of Ekimu, and is vengeful and jealous. It is said that he is the son of Gaia and Genesis, but this has not been confirmed.

History
Makuta was born an unknown time ago. Along with Ekimu, he fought against Umarak the Hunter. After this, he and Ekimu were the primary governance until he grew jealous, and forged the Mask of Ultimate Power, using the 6 Main Elements. Placing this upon his head, he grew corrupted, like his father. Ekimu knocked the vile mask off his brother, and Makuta was sent to the Shadow Realm, where he and his legion plotted against Okoto.

1 year before his defeat, Makuta sent Kulta and the Skull Legion to raid the city of its valuables, and prepare it as the stronghold of Makuta's reign. However, the Toa of Tahu's Team stopped this, so Makuta sent Umarak to hunt down the Elemental Beasts. Through an unfortunate series of events, Umarak obtained the Mask of Control. However, much like Makuta, Umarak grew corrupted in the presence of such power, and placed the mask on his head, forever mutating the mask, and mutating the unfortunate Hunter into a Destroyer. Using the Mask of Control to control his new slave, he commanded him to start rebuilding the Mask of Ultimate Power. This was halted, again by Tahu and his gang. This is commonly called the Defeat of Makuta, the modern base on which the years are measured.

He attempted to once more retake Okoto, through Acidoro the Collector, but that plot was quickly thwarted by the Primordials. Makuta, at this point, was not jealous anymore, and left Acidoro to his own devices.
