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. However, Makuta grew jealous, since the islanders of Okoto valued Ekimu's masks more than his. When Makuta created and donned the heretical Mask of Ultimate Power, Ekimu saw this, and knocked it from his brother'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 an emblem of the Mask of Creation.

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 the Skull Grinder to his forge to be destroyed. When they arrived at the forge, the 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 Gatling blasts, and to knock the Mask of Creation from the Skull Grinder's face. He took back the mask and repaired the Golden Masks of Power, which were damaged in the conflict. He told the Toa 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

 * Ekimu is reminiscent of the original BIONICLE characters Mata Nui and Artakha.
 * He is similar to Mata Nui in that, Ekimu is Makuta's brother and the creator protagonist. He is notably shorter however, as Mata Nui was Toa sized in his Ignika created body whereas Ekimu is the size of an islander.
 * He is also similar to Artakha because he wears the mask of creation which is worn by Artakha in the original storyline.
