It was his second attempt. His first such plant, KarzahniThe Karzahni PlantThe sentient prototype of the Morbuzakh, created by Teridax and abandoned in the labyrinth beneath Mata Nui after it proved too willful to control., turned out too powerful and intelligent for his purposes, so he abandoned it and made the Morbuzakh instead.

The plant's first move was to grow vines around the Great FurnaceThe Great FurnaceThe largest furnace in Ta-Metru, site of the Morbuzakh King Root's nest and the recovery of the fused Great Disks that became the Kanohi Vahi. and drive the Matoran away, leaving it free to grow its King Root in the middle of the huge building, fed by the molten protodermis and the flames. The root grew to well over a thousand feet tall. From there its vines spread throughout the city, attacking buildings and Matoran seemingly at random, though mostly around the edges of each MetruMetruIn the Matoran language a metru was a single district of Metru Nui; the city was divided into six such districts, one for each element, and the term covered both the place and the elemental community that lived in it.. The VahkiVahkiMetru Nui's mechanical law enforcement squads, designed to maintain rigid order but ultimately undermined by chaos beyond their programming. and the Matoran fought back, but the plant was too strong for them.

Purpose#

The job of the King Root, and of the MorbuzakhMorbuzakhA sentient plant monster created by Teridax to terrorize Metru Nui and control its population through fear. as a whole, was to drive the MatoranMatoranThe most abundant species in the Matoran Universe, chosen by Mata Nui to inhabit and maintain his cosmic body. of Metru NuiMetru NuiThe city beneath Mata Nui functions as the Great Spirit's brain, housing the Matoran whose labor keeps the god alive. into the centre of the city, to the Coliseum. Once they were gathered there, Teridax and the VahkiVahkiMetru Nui's mechanical law enforcement squads, designed to maintain rigid order but ultimately undermined by chaos beyond their programming. could easily capture them and seal them in Matoran SpheresMatoran SphereRound containers that wiped memories and hid Makuta Teridax's manipulation of the Matoran.. The attacks on outlying districts and the vines that tore through buildings all served that one herding goal. (BIONICLE: Encyclopedia Updated)

Frequently asked questions

What was the King Root in Bionicle?
The King Root was the central, sentient core of the Morbuzakh, a giant plant created by Makuta Teridax to terrorise the city of Metru Nui. It grew in the Great Furnace of Ta-Metru and extended vines across the city.
What was the purpose of the King Root?
The King Root and the Morbuzakh existed to drive the Matoran of Metru Nui into the Coliseum at the centre of the city. Once concentrated there, the Matoran could be sealed in Matoran Spheres, have their memories erased, and pass into the long stasis Teridax intended for them.
How was the King Root destroyed?
The Toa Metru tricked the King Root into drawing them closer, then unleashed the combined power of the six Great Disks. The disks formed a sphere of energy around the root that cut it off from the rest of the plant. The vines across the city withered, the root crumbled to dust, and its death throes wrecked the Great Furnace.
How did the Toa Metru find the King Root?
The Ga-Matoran Vhisola had studied the Morbuzakh and worked out that it thrived on heat and had to be beaten at its King Root. Nokama realised that meant the root had to be in the Great Furnace of Ta-Metru.
Why was the King Root significant in the Metru Nui story?
It was the first major opponent the newly formed Toa Metru defeated together and the reason they gathered the six Great Disks. Its admission that it had been commanded to drive the Matoran to the centre of the city hinted that someone else was directing events, a thread that ended with the unmasking of Teridax as the false Turaga Dume.
