Ekimu

Ekimu was one of the legendary Maskmakers on Okoto and the brother of Makuta. He wore the Mask of Creation. He was awakened by the Toa using their elemental powers. Then he joined them to help find the Mask of Creation.

History
Ekimu was a legendary crafter of Masks of Power, alongside his brother Makuta. Makuta, however, grew jealous, since the islanders of Okoto valued Ekimu's masks more than his. When Makuta created and donned the Mask of Ultimate Power, Ekimu saw this, and knocked the mask from Makuta's face. The resulting shockwave put both brothers into a deep slumber. With his last breath, he whispered the Prophecy of Heroes to the Protectors. The Protectors forged him a special golden mask and laid him to rest in a gold coffin decorated with a Mask of Creation emblem.

After the Toa arrived on Okoto, Ekimu guided them to collecting their Golden Masks and bringing them together at the Ancient City. There, Ekimu once again guided the Toa to his resting place, where they combined their elemental powers in order to awaken him. After being freed, he explained to the Toa that his Mask of Creation had been taken by Makuta's minion Kulta to his forge to be destroyed. When they arrived at the forge, Skull Grinder put on the Mask of Creation. Ekimu told the Toa to distract him, as he searched for pieces to create a new Hammer of Power. When he finished, Ekimu used his weapon to fire Elemental Ice blasts, and to knock the Mask of Creation from Skull Grinder's face. He took back the Mask of Creation and fixed the Golden Masks of the Toa which were cracked in the conflict. He told the heroes that he had never seen such bravery, and that they were worthy heroes.

Powers and Tools
As a Maskmaker, Ekimu was able to create Masks of Power. He wielded the Hammer of Power, which he used to shape his creations, as well as using it in battle. He also wielded the Saw Shield for protection against enemies and for flight.

He also wore the Mask of Creation, until it was lost in the aftermath of his conflict with Makuta, replaced with a Golden Protector Mask. While he rested in his tomb in the Ancient City, he was able to telepathically communicate with the Toa through their Golden Masks of Power.

Trivia

 * Unlike in the original BIONICLE storyline, where Mata Nui was the size of the average Toa, Ekimu is only the size of the average Islander.
