Hewkii

Hewkii was a highly famed athlete. He had a special bond with Macku. He was later a Toa of Stone.

Matoran
Hewkii is a champion at the sport of kolhii, and served on the Po-Koro kohlii team. He was the strongest Po-Matoran on Mata Nui. And his best friend was Macku.

Toa Inika
After the Matoran's return to Metru-Nui, Hewkii and his fellows had begun to reconstruct the once great city when the Turaga's dark news about Mata-Nui's fate was discovered. After the Toa Nuva had left without giving word to the Matoran he joined Jaller in a city-wide strike to force the Turaga into telling them what had occurred to draw their protectors away. Jaller contacted him and five other Matoran to join him on the dangerous journey to Voya Nui after he had found the truth. They all knew that their fates were very likely to be tragedies, but all six bravely traveled on into what they would soon find out to be Karzahni's realm. He escaped with the others and was transformed into a new Toa Inika by a bolt of lightning from the Red Star. After his transformation he was puzzled to see his armor had turned a yellow and irony color, and was disappointed when nobody else made an issue of it. He later was able to take down Vezok with his Mask, the Kanohi Sanok, Mask of Accuracy. He joined the other Inika in their journey to the Chamber of the Mask of Life and faced off against their many foes before achieving victory with his allies.

Toa Mahri
After the events on Voya Nui, Hewkii and the others ventured down to the Pit, being transformed by the Ignika in the proccess. Due to his recent transformation he lost his electric powers, tools and Kanohi Sanok - but gained a Kanohi Garai, the Mask of Gravity, an Aqua Warblade, and two inter-locking electric chains, becoming the Toa Mahri of Stone, Hewkii Mahri.

Immediately after being transformed, Hewkii noticed the 300 foot-long Venom Eel heading for them and the Toa Mahri began to fight it. In the end, he used his Garai to increase the Eel´s weight and it plunged to the sea floor, unconscious.

The Toa then headed for the underwater city Mahri Nui, where they were put in charge of freeing the fields of Airweed from the Barraki´s armies. Instead they were taken to caves by the Barraki, but Hewkii quickly used his Garai again to decrease his Takea guard's gravity, making it float. Later he reunited with Nuparu and Hahli.

He and Nuparu began exploring the sea caves and later was surprised by Nuparu in a cave by testing a multibarreled weapon. Hewkii took one for his own and a load of them went to the other Toa.

They reunited in Mahri Nui, where they decided on what to do to get the Ignika, and decided to split up and explore the sea. Hewkii and Nuparu later found and began exploring a trench in the sea floor.

While doing this, they talked about Metru Nui until they found what looked like a tree stump buried in the sand with many "branches", then they realized that they weren´t branches, but Venom Eels.

His last act of heroism underwater was trying to bide Matoro time with the rest of his Toa tem, fending off the Barraki and their armies.

Hewkii is now back in Metru Nui, thanks to Matoro who used the Ignika to teleport the other Toa Mahri and turn them into air breathers again.

Hewkii was the worst swimmer out of all the Toa Mahri.

Powers and Abilities
As a Toa of Stone, Hewii could control stone, meaning he could create fists and hammers of rock, among other things.

Inika: As an Inika, Hewkii's elemental powers were combined with lightning.

Mahri Hewkii's stone powers were reduced to normal levels after being altered by the Mask of Life.

Mask and Tools
Inika: Toa Inika Hewkii's organic mask was the Kanohi Sanok, Great Mask of Accuracy, which allowed him to throw things and hit his target without fail.

His weapons were a Laser Axe with a Climbing Chain, as well as a Zamor Launcher.

Mahri: Hewkii Mahri's Kanohi mask was the Garai, Mask of Gravity. This useful Kanohi allowed him to increase and decrease an opponent's gravity.

The Ignika granted him an Aqua Warblade, with electrified chains, and later he aquired a Cordak Blaster. One of the chains was shattered by Gadunka, but later repaired.
