Akamai

"Welcome, Toa of Water. Do not be afraid-- your body is safe in the ocean's embrace. Only your mind has journeyed here to behold your future. [...] We are what you and the other Toa shall become. When each of you has found all the Great Masks of Power, then shall you be ready to join together and defeat Makuta."

- Toa Kaita Wairuha and Akamai, Comic 3: Triumph of the Toa

Akamai was the Toa Kaita of Valor, formed by Tahu, Onua, and Pohatu.

Biography
Akamai was only been formed once. When the Toa Mata/Toa Nuva first went into Mangaia, they encountered the Manas, crab-like guardians of the Makuta. They proved too hard to defeat separately, so the Toa fused with each other: Tahu, Onua, and Pohatu into Akamai, Gali, Lewa, and Kopaka into Wairuha. Upon entering Makuta's inner sanctum, the two Kaita were forcibly unfused as a result of Teridax's dark energy. Akamai wore the Kanohi Aki.

Nuva Kaita
If Tahu Nuva, Onua Nuva, and Pohatu Nuva had ever fused, they would have formed Akamai Nuva. He is now unable to be formed, as Tahu is a Toa Mata again.

Powers and Equipment
Akamai wore the Kanohi Aki, the Great Mask of Valor, which gave him the powers of Shielding, Strength, and Speed. He controlled the elements of Fire, Stone, and Earth. He carried a Fire Sword and a club and wore Feet Additions. He was capable of channelling his elemental powers through these weapons.

If Akamai Nuva were formed, he would have worn the Aki Nuva, the Nuva Mask of Valor, which would provide enhanced shielding, speed, and strength.
