Core Processor

The Core Processor was a large network of mechanics that served as the "brain" of the Great Spirit Robot, located far beneath Metru Nui.

History
The Core Processor was designed by the Great Beings and built into the Matoran Universe prior to the Shattering of Spherus Magna. Two Glatorian guards were placed in suspended animation to wake to monitor and maintain the machinery while Mata Nui's consciousness resided within it. However, when the Great Cataclysm occurred, Mata Nui's consciousness was separated from the machinery, the system was put on standby, and the two Glatorian were killed.

It wasn't until 1,001 years later when Toa Mahri Matoro sacrificed himself with the Kanohi Ignika for Mata Nui to return to the Core Processor. But before the Great Spirit's consciousness could return to it, Makuta Teridax slipped in and took over the processor, allowing him to control the entire Mata Nui robot.

Before Spherus Magna was reformed, Teridax was struck by one of the moons of Bara Magna, finally killing the Makuta. In these moments, the moon destroyed the processor, shutting it down for good.
