Raeser was one of many Matoran kidnapped by the Brotherhood of Makuta for their Nui-Matoran project. After being put through a number of experiments, Raeser emerged as one of roughly twenty surviving Matoran who were brainwashed and sent to be cared for and trained by various Makuta. Raeser was placed in the care of Makuta Zerrek and quickly became the Makuta's friend and confidant. In the wake of a Nui-Matoran killing his guardian, a message was sent for all the Nui-Matoran to be put to death. Unable to bring himself to kill his only friend, Zerrek healed Raeser's mind himself, and the pair ran from Tedra Nui. When word came that Zerrek had refused an order, he was declared a rouge Makuta, and the Brotherhood sent agents to bring him and Raeser in. The pair ran for years, staying just a few steps ahead of their Brotherhood pursuers, disguising themselves as a Toa of Sonics and a normal Matoran of Earth.
The pair eventually came to Algiren, where they were rescued from freezing by Toa Tsonclad. After spending a few days to recover, the pair spent a day in the village, having a few close calls with the village's Toa. The day they left the village, the Brotherhood agents caught up with them. To spare Algiren, Zerrek and Raeser turned themselves in. Despite their cooperation, the Brotherhood agent ordered his Rahkshi to destroy the village, but moments later, the pair broke free and flew in to fight the Rahkshi and destroy the Brotherhood's airship. The Toa of Algiren, after seeing the villagers to safety, returned to help and quickly realized that the pair were not what they had seemed. After defeating the last of the Rahkshi, Zerrek collapsed. After Raeser explained themselves to the Toa, they stayed in Algiren a few days more to allow Zerrek to regain his energy. The pair then left Algiren, heading for Aleris.
Powers and AbilitiesEdit
Raeser has the power of telekinesis which manifests itself in light green energy tendrils that extend from his person. He can manipulate multiple objects at once and has shown, on occasion, to have more power than a Kanohi Matatu can offer.
As an Onu-Matoran, Raeser is also built physically stronger than most Matoran. His night vision, however, was eliminated during the Makuta's experiments.
Raeser is a generally pleasent individual, despite what he has gone through. He tends to keep a smile on his face and harbors no ill will towards Zerrek, However, he despises the Brotherhood as a whole. Despite this, he has no desire to be rid of his power and harbors a deep frustration at not being able to use it to help others.
