Legendary Elements
There also existed, exclusively within the Matoran Universe, three incredibly powerful elements, incapable of being wielded by any living being. They embodied the major factors that governed the lives of the Matoran, and most others living within the Great Spirit Robot. These are as follows:

Life

 * Primary Color: Gold
 * Environment: None
 * Prefix: None

Creation

 * Primary Color: Unknown
 * Environment: None
 * Prefix: None

Time

 * Primary Color: Bronze
 * Environment: None
 * Prefix: None

(Note that these elements existed solely within the Matoran Universe, and were directly connected to three ancient Kanohi. If any of these legendary masks were to be destroyed, their elements would cease to function, and all the beings within the Great Spirit Robot would lose their ability to create new things, acknowledge time, or even live.)

Bara Magna

Water

 * Primary Colors: Blue
