Deriahk

Early Life
Deriahk is an ancient Skakdi, and may very well be older than Mata-Nui. Some have said that he was a hero long before Toa even came into being. He left Zakaz at the arrival of Spiriah and began a quest to find Artakha, believing that he could shelter there away from the destructive might of Spiriah. He never succeeded in finding the Great Refuge, but he arrived at Takiw Nui. There, he met Vavakx and became his assistant. Some time after this, he has taken over an organization called 682Sitrius, and now the group serves Vavakx and the Order of the Great Creators.

The Pit
Many years later, Deriahk went to the Pit. He was wounded by Barraki Pridak and left for sea beasts. After escaping, he met with Vavakx to plan how to get the Kanohi Ignika. Deriahk was told by to abduct the Ga-Matoran Kryehk who picked the Mask of Life during its fall and bring her to his cave.

Later, Deriahk and Vavakx discovered Veuy and Manauhk. After a battle, Deriahk sacrified part of his own life energy to allow Vavakx to shapeshift and he fell unconscious, but he had freed Vavakx from his locked form and in gratitude he teleported Deriahk to safety.

Search for Mata Nui
Vavakx, Deriahk, Tahkod and Khad has now appeared on Bara Magna to search for Mata Nui. There they met two Glatorian and two Agori fighting each other. He was later tracked down by Hantrek. Later, Tahkod teleported both him and Gryk from the arena. Gryk was taken for interrogation by the Order of the Great Creators on the New Takiw-Nui.

He woke up and Gryk accepted to join the Order of the Great Creators. They tried to stop Dark Vavakx and Dertbrez from destroying New Takiw-Nui but they failed when both of them were teleported. They followed Dertbrez back to Bara Magna were Deriahk shape-shifted into Hydreriahk.

Abilities and Traits
Deriahk is very dedicated to his job. Even if he knows that what he is doing is bad, it does not matter to him. He pulls out all the stops to beat his opponents, because that is his duty to Vavakx. He is extremely angry against Spiriah, blaming him for destroying his brothers in Zakaz.

Deriahk has the ability to send electrical shocks.

He wields claws that are made of Protosteel and were given to him by The Order of the Great Creators, these weapons are actually part of his body.

Unlike the other Skakdi, Deriahk does not have a spine. Also, he has a great deal of mental discipline, and can use Great Kanohi, notably the Kanohi Garai. Now, he is also larger than most other Skakdi because he rebuilt himself.
