Mother Computer
Buried deep underground in a ruined city on the planet Gaia—future Earth—is the Mother Computer (マザーコンピュータ Mazā Konpyūta), a towering monolith which stands testament to all the accomplishments of its mysterious creators... and all of their folly.
Despite millennia of disuse, it still functions... unfortunately.

Built by humanity, powered by Angolmois Energy, and kept in an underground chamber, the Mother Computer was consulted regarding things of great consequence.
However, when humanity's Selectors rebelled, the Quintessons took advantage of this opportunity, corrupting the Mother Computer via Angolmois Energy that was influenced by their wicked hearts. After the Quintessons proposed an alliance with humanity to wipe out the Selectors before they could drive their creators from Earth, Spike Witwicky, unaware of the Mother Computer's corruption, asked the computer if they should ally with the Quintessons, to which it answered in the affirmative. Volcanicus comic 2 The attending Quintesson Judge admitted to their deception regarding the Mother Computer after shooting Spike through the chest, and Angolmois Energy emerged from the chamber's floor as the Quintesson ranted.

After arriving on Gaia, Galvatron followed traces of Angolmois Energy and discovered the Mother Computer. He directly interfaced with it and demanded it show him the most powerful forms in the planet's history; it imprinted the templates for a drill tank and a massive dragon onto him, but the strain put Galvatron into a deep slumber. Megastorm, using a more standard computer interface, requested specifications for weapons and construction vehicles suited to Gaia for the other Predacons to use. Starscream and BB captured Lio Convoy and brought him to the Mother Computer site, but he escaped and chased the Predacons off. White Lion, Run!
Much later, as the artificial planet Nemesis passed by Mars, a control robot emerged from Mars and headed for Gaia. He contacted the Maximals and NAVI in order to make them take him to the Mother Computer. Once there, he entered the computer and activated a doomsday program designed to crash the Moon into planet Gaia and eliminate the contaminated Angolmois Energy before it would be able to threaten the universe. Emissary of the Fourth Planet
With the help of Galvatron, the Maximals were able to break through the Mother Computer's defenses, allowing NAVI to enter the computer herself and reprogram it to deactivate the doomsday program. The Moon's descent was halted just in time. The Crisis of Planet Gaia
