Force Sphere

"It's a quick-race to see which happens first -- the sphere tears me apart or it implodes! Either way, no more Matau..." — Toa Metru Matau, Disks of Danger

Occasionally, there is a flaw in a Chute System, which causes a piece of the Chute's field to break off and wrap around itself, becoming a Sphere of magnetic energy, called a Force Sphere. Force Spheres travel through Chutes at high speed, sucking in tools, bits of junk, Great Disks, and other things. The longer the Sphere exists, the stronger it becomes, until it causes the Chute it was traveling in to collapse. The Sphere then implodes under the wreckage, destroying its contents.

During the quest for the Great Disks, Matau had to retrieve Le-Metru's Great Disk from a Force Sphere. The Toa managed to create a tornado inside it to push himself out. After that, the Sphere destroyed The Notch.
