Origin within the Chute System#

The chutes were streams of protodermis held in place by an electromagnetic field that pulsed, weakening and strengthening every few seconds so that solid objects could pass through at the right moment. (BIONICLE: Metru Nui, City of Legends; BIONICLE Adventures 2: Trial by Fire)

A Force Sphere was one way that field could fail. Occasionally a flaw in a chute let a piece of the field break away and wrap around itself, closing into a sphere of magnetic energy. (BIONICLE: Encyclopedia; BIONICLE: Encyclopedia Updated)

Behaviour inside the chute#

Once formed, a Force Sphere travelled through the chute at high speed, sucking in tools, bits of junk, KanokaKanoka DisksMetru Nui's most versatile artifact: flying disks equally at home in sport, combat, and crafting. disks and anything else in its path. It didn't weaken as it went. The longer it existed, the stronger it became. (BIONICLE: Encyclopedia; BIONICLE Adventures 2: Trial by Fire)

That growth had only one end. Eventually the sphere brought down the chute it was travelling in, then imploded under the wreckage, destroying everything it had gathered. (BIONICLE: Encyclopedia; BIONICLE: Encyclopedia Updated)

The Le-Metru Great Disk in the Notch#

The Notch was an ancient, rarely visited section of the chute system, a tangled mess of chutes that the Le-Matoran used as a lesson in patience. During the search for the six Great DisksThe Great Disks: six Kanoka of level nineThe Great Disks were six Kanoka of Metru Nui, each at the maximum power level of nine, one hidden in every district. The Toa Metru recovered all six., which VakamaVakamaA Ta-Metru maskmaker transformed into the Toa Metru of Fire, leader of his team through the Visorak war, and Turaga of Ta-Koro for a thousand years. believed could defeat the MorbuzakhMorbuzakhA sentient plant monster created by Teridax to terrorize Metru Nui and control its population through fear., MatauMatauA former Le-Metru test driver who became a Toa Metru, Matau wielded air, illusion, and shape-shifting before sacrificing his Toa power to wake the sleeping Matoran., NokamaNokamaNokama served as Toa Metru of Water, endured the Hordika mutation, and led Ga-Koro and later Ga-Metru as Turaga through three eras. and the Matoran OrkahmOrkahmOrkahm was a Le-Matoran Ussal rider of Le-Metru, Matau's chief rival, one of the six finders of a Great Disk, and later a Gukko Force member on Mata Nui. and Vhisola went there looking for the Le-Metru disk. (BIONICLE Adventures 2: Trial by Fire)

After searching for some time they spotted the disk, caught inside a Force Sphere that would soon implode and destroy it. Matau jumped into the sphere, found the disk, and used his air powers to create a tornado that flung him back out just before the implosion. (BIONICLE Adventures 2: Trial by Fire; BIONICLE 17: Disks of Danger; BIONICLE 2: Legends of Metru Nui)

The Force Sphere then imploded and destroyed the Notch. The Great Disk survived in Matau's hands. Vakama later merged the six Great Disks into the Disk of Time and forged the Kanohi VahiKanohi VahiThe Kanohi Vahi was the Legendary Mask of Time, forged by Toa Metru Vakama from the six fused Great Disks of Metru Nui during the city's evacuation., the Mask of TimeMask of TimeThe Kanohi Vahi is the Matoran Universe's deadliest mask, capable of stopping or accelerating time, and its creation nearly tore Metru Nui apart., from it.

Hazard classification and standing procedure#

When there was trouble in a chute, the operators could slow or stop the flow, but they believed reversing it might make the whole system explode. Damaged chutes were closed to the public until they were back to normal, though some Matoran used them illegally anyway. (BIONICLE: Metru Nui, City of Legends; BIONICLE 2: Legends of Metru Nui)

Effects on the Chute network#

A Force Sphere left a hole in the network: the chute section it destroyed was gone. The Notch was wiped out by the sphere's implosion right after Matau escaped. (BIONICLE Adventures 2: Trial by Fire)

Status in the canonical record#

Force Spheres appear in the 2004 Metru Nui story and are described in the BIONICLE encyclopedias under their own entry. They are a hazard of Metru Nui's chutes specifically, and the name refers to nothing else in BIONICLE: it has nothing to do with the Matoran SphereMatoran SphereRound containers that wiped memories and hid Makuta Teridax's manipulation of the Matoran. Teridax used to imprison the city's population. (BIONICLE: Encyclopedia; BIONICLE: Encyclopedia Updated)
