Rhotuka

"Being wheels of pure energy, Rhotuka spinners make very little noise when they fly."

- Nararator, Birth of a Dark Hunter

Rhotuka were wheels of energy with various powers. All creatures have the ability to make Rhotuka, but they would be useless unless one also had a launcher to fire them with. Many Rahi and creatures of the Bionicle universe had developed natural launchers, but artificial ones were used by creatures such as Toa and some of the Dark Hunters. The layer of energy that bonds Rhotuka together make the spinners tangible, so they can be ridden if one should choose to do so. Each creature with a Rhotuka launcher creates their own unique spinner power. The powers of these Rhotuka are derived from that character's morals, ethics and affinities. For example, only a Toa of Fire could use a fire spinner, and Sidorak, who valued obedience in his troops and had a desire for domination, fired Obedience spinners.

In Set Form
Rhotuka could be fired from the launchers included in many sets by pulling an included rip cord. The spinners would rotate like rotor blades and lift off, flying to surprisingly lofty heights. If pulled hard enough, a Rhotuka spinner could go as high as 50 ft, and as far as 70 ft, according to a Bionicle commercial.
