Metrados

Makuta Metrados is the Leader of the Shadow Makuta Brotherhood, a former Dark Hunter, and the former third in command of the Brotherhood of Makuta.

Creation
Metrados was created like the other Makuta: by Mata Nui. When Teridax rebelled, he went with him. He was then made third in command, since Miserex was already second.

Brotherhood of Makuta
During his time in the Brotherhood of Makuta, he was sent on many missions. Metrados was first sent to Daxia, after hearing rumors of an organization that serves the will of Mata Nui and gaining permission to go. He then searched the island for many months, studying the land, questioning the inhabitants, and searching all around for their base. After his failure, he returned to the Brotherhood base. He went to Teridax's lair, where he had his next assignment given to him before the arrival of Takanuva. He then witnessed the arrival of Takanuva, Teridax's defeat at Kohlii, the fusion of the two, and the apparent death of his leader. Metrados then came to his remains, and stole the Staff of Shadows.

He then flew to Metru Nui with his shoulder jet packs, and arrived a few hours before the Matoran and Turaga did. The Makuta then decided to seek out a new master, and flew around the Matoran Universe. Eventually, he found an island with a strange looking being on it. Metrados later found out the being he met was The Shadowed One, and he asked Metrados to join his group, the Dark Hunters. He accepted the offer, and the pair, along with the other members, created their headquarters.

Dark Hunters
After the creation of the base, he was sent on his first Dark Hunter mission: find and kill Makuta Kojol. He followed the Order of Mata Nui to the location where Kojol's virus was made to eat protosteel. After his essence escaped his body, Metrados somehow obtained it and put it in a furnace.

His next mission was to locate the island of Artakha. After many months of flying around and searching, he finally succeded in finding the island, and when he went to report back, Artakha erased his memory of visiting the island, and replaced it with a fake memory of him failing. After reporting back, he went back to his room in the base to wait for his next mission.

He later got a team assignment: him and Nidhiki would follow and track down Miserex, and once they had him in a good enough situation, Airwatcher would kill him. The mission was going good at first, but when Miserex found them out, he fought the pair. After losing, he decided to rejoin the Brotherhood of Makuta.

Brotherhood Again
He was later accepted by the Brotherhood again. Soon after, Metrados was called into a breifing room with Teridax. When he entered, the Makuta leader tried fighting him. Metrados then revealed that, while he was a Dark Hunter, he spent some of his time using his Kanohi Jamok to absorb mask powers of others. So far, he had taken the powers of a Kanohi Kakama, Hau, Kaukau, Matatu, Suletu, Komau, Calix, Artrhon, Shelek, and Kualsi. He planned to steal and absorb a Tryna, reanimate Tuyet, have her recreate the Nui stone, and take it's power. When he learned that Teridax planned to do the same, he quit the Brotherhood of Makuta.
