Nuju

Nuju was the Toa of Ice on Metru Nui and later the Turaga of Ko-Koro.

Matoran
Not much is known about Nuju's life as a Matoran. It is known that he was a Ko-Matoran scholar of Metru Nui working in a Knowledge Tower, and that at one point he had a mentor named Ihu. Then one day Toa Lhikan gave him a Toa Stone and a map to the Great Temple, where he met Vakama, Nokama, Matau, Whenua, and Onewa, and they all became Toa Metru.

Toa Metru
Nuju was the Toa Metru of Ice and guardian of Ko-Metru. Nuju was a well-respected seer before becoming a Toa - and sometimes he wished he could go back to that role. While he took his duties as a Toa seriously, it was not a job he would have volunteered for. Being a Toa Metru meant having to work with others he was not sure he likes and having little time to study. Although Nuju did not have much faith in Vakama's visions, he was practical enough to know that someone had to be the leader. That did not mean Nuju would follow orders he thinks are foolish - like any Ko-Matoran, he preferred to go his own way and choose his own actions. Although he sometimes seemed aloof, he was usually mapping out the consequences of a plan before suggesting it. Nuju was always focused on the future, which explains why he argued regularly with Toa Whenua, who revered the past.

Nuju and Whenua worked together to find the Matoran who knew the locations of the Great Disks (and later the Disks themselves) of Onu-Metru and Ko-Metru. Along with the other Toa Metru, Nuju fought the Morbuzahk and the Krahka.

Nuju, Whenua, and Onewa were later arrested by the Vahki and put into a chamber with Turaga Lhikan, who taught them their mask powers. They were rescued by the other Toa, and the Toa Metru fought Makuta. Then, carrying six Matoran in Matoran Pods, they traveled to Mata Nui, encountering giant sea Rahi and Kralhi on their way.

Nuju explored the island of Mata Nui and named a mountain there Mount Ihu, after his deceased mentor. He decided it would be a good place for the new Ko-Metru, or more fittingly, Ko-Koro. They headed back to Metru Nui, having several misadventures on the way, and were ambushed by Visorak and mutated into the Toa Hordika.

Toa Hordika
As a Toa Hordika, Nuju, used to being in control of his emotions, was among those most anxious to be cured of his mutation. Nuju's tools were Hordika Teeth, which he used to summon flying Rahi or to charge his Ice Rhotuka.

Toa Hordika Nuju and Rahaga Kualus searched for Vahki Transport parts in Ko-Metru, and eventually ran into Onewa, Pouks, Krahka, and Tahtorak. They went to the battle unfolding at a hangar in Le-Metru, and the Toa Hordika won the battle.

Later, Nuju and the other Toa, minus Vakama, went searching for the mythical Rahi Keetongu, and found him in Ko-Metru. Nuju and the others fought in the final battle against the Visorak and one of Nuju's ice spinners contributed to the Toa Hordika's attempt to destroy Roodaka, ending up in the freeing of Makuta. Keetongu restored the Toa Hordika to their original forms, and at some point Kualus taught him the language of the birds.

Nuju and the other Toa traveled back with the Matoran to Mata Nui and he sacrificed his Toa power to awaken the Matoran, becoming a Turaga.

Turaga
As a Turaga, Nuju gave up the Matoran language and spoke the language of the birds taught to him by Rahaga Kualus as not to forget Metru Nui's fall. He taught Matoro the language and used him as his translator, although he did speak Matoran on necessary occasions (for example, when Toa Kopaka first arrived). Upon hearing of the death of Matoro, Nuju went into mourning for his translator and good friend. He has later on found a new translator, but it is unknown who it is at the moment.

Powers and Tools
Nuju controlled the element of ice, and thus could cause blizzards, create ice slides, and create anything out of ice. As a Toa Metru, he carried Crystal Spikes. As a Toa Hordika, he carried Hordika Teeth, and as a Turaga, he carried an Ice Pick. He wore the Kanohi Matatu, Mask of Telekinesis, which allowed him to move objects with his mind.

Personality
Nuju disliked anyone who didn't look to the future. He had a cunning wit and he was known to voice his dislike of anything. He had a razor-sharp mind and incredible analytical skills. He always looked to the future, helping the Toa get out of dangerous situations. However, because of this, he often disagreed with Whenua, who insisted on reviewing the past for answers.
