"Then i will claim this place as my own. Those who ssssurvive can ssserve the Morbuzakh or perisssh."

- Morbuzakh to the Toa Metru and their Matoran allies.

The Morbuzakh was one of the antagonists that was introduced in the 2004 BIONICLE storyline. It was a massive, sentient plant-like creature who was created by Makuta Teridax as part of his master plan of taking over the island of Metru Nui and overthrowing the Great Spirit.

History
The Morbuzakh was created by Teridax several days after his defeat in the hands of Toa Hagah in Destral. He first creates the plant-like creature called the Karzahni, but he later found out that it was too willful and intelligent for his purposes, so he abadoned it and instead create the Morbuzakh. Then, he formulated the plan: the Morbuzakh was to drive the Matoran to the Coliseum, where he and the Vahki cam easily capture them and placed them into the Matoran Spheres. To this end, Teridax told the Morbuzakh that he will let it rule Metru Nui after his plan was fulfilled.

When Teridax replaced Turaga Dume with the help of the Po-Matoran, Ahkmou in the months before the Great Cataclysm, he instructed him to secretly plant the Morbuzakh seeds in Ta-Metru. Ahkmou then sneak into Ta-Metru and plant the seeds in the Great Furnace. The Morbuzakh's first action was to grow vines in the area

Personality
Not much was known more of the Morbuzakh's actual personality but it also have the ability to speak in the telephatic way and was known to be destructive and aggresive.
