Exerius

Exerius is a Demitoa that had devised the first hardsuit after the collision between the Hero Factory and Bionicle Universes. He is one of the engineering brothers, and his sibling is Seirez. Not only has he created the hardsuit, but many other inventions. These inventions include, but are not limited to:
 * Improved Hero Cuffs
 * Retractable Sword
 * Double-Barreled Plasma Shotgun
 * Charged Plasma Rifle
 * Powerful uranium energy core

History
Exerius was a being that worked in Onu-Metru, even though he was a Matoran of Electricity. After he discovered a Toa Stone in a small cave behind an underground waterfall, he was indecisive whether he wanted to have the responsibilities of a Toa. In the midst of transformation, he let go of the stone, and was trapped in mid-metamorphosis. He became a Demitoa, one of the first to be seen by the public. He packed his bags and left Onu-Metru, for he feared being an outsider. After years of isolation, he had discovered a rift to the Hero Factory universe, and entered to explore the world beyond him. He logged his findings in a small, leatherbound journal that he kept for years until it was incinerated while he was testing his new weapons technology. He began creating a powered suit, to help in combat since his electricity abilities weren't very formidable or stable. Today, he is a part of the Nuvai Alliance, assisting his kind against the raids of the minifigures.

Other Information
His brother Seirez was not his brother, but a clone created when he was attacked with the Spear of Fusion. Originally, Seirez seeked Exerius' technology, which is the reason why he owns a hardsuit today. However, after a change of heart, Seirez is now allied with his "brother" and the Nuvai Alliance.
