Sydemus

"Oh Im so delighted you've showed up, Now I can kill you and complete my Rahi invasion without the trouble of finding you."

- Sydemus to Toa Escavo, Catastrophy of The World Sydemus was a very powerful Makuta who was fond of the affection of Rahi more than the Affection of Other species. Teridax even commented of how 'troublesome' he was to help Teridax take over all of the Matoran race. Resulting in him being sent into a comet with some 'disagreements with the terrible Makuta.'

History
100,000 years Sydemus along with the other Makuta Species were created. Although he was part of the brotherhood of Makuta, he Isolated himself from the other Makuta for a long time. Simply trying to figure out ways to create highly inteliigent rahi even more intelligent then the Artakha Bull. Instead of becoming Jealous of Mata Nui being praised by the matoran. He became jealous of the fact that Matoran considered almost all species of Rahi being unintelligent. An example would be the Kikanalo for a period of time.

75,000 years ago. Teridax stated his devious plans. Sydemus along with Miserix denied him. During this time, Sydemus had used a peculiar virus that gave him a more rahi-like appearance along with quils that surrounded his armor. He already 500 years before used his quils as a 'test' against a member of the League of Six Kingdoms, resulting in the other makuta becoming hesitant of this. Teridax found a solution for it by sending him into a comet that was circling around The Solis Magna System. Sydemus was not seen in the Matoran universe for a very long time. Within the comet which was slowing turning into an astroid, he found liquid protodermis and many different kinds of viruses he never seen before. Upon the discovery he dedicated his life to creating extreme intelligence that would rival the Artakha Bull's. He later even started creating rahi who's powers would rival Toa and Makuta alike in his now determine goal for returning to Aqua Magna one day to make rahi the dominate species. During this time, a fasinated Great Being studying the comet decided to create a machine to draw the asteroid closer to Spherus Magna for further study of the great rock. Resulting in the return of the Ambitious Makuta along with his creations. The Asteroid nearly collided into an Matoran-Agori village untill a band of Glatorians and Toa aiding in slowing the Asteroid untill it now floats over the Village.

The Begining of a Nuisance
As Sydemus started more actively testing his experiments. The same Great Being turned himself into a ghost-like thing in order to travel every nook and cranny of the rock to see peculiar things. Along with Sydemus.
