>The Autobot Matrix of Leadership records the bearer's life and experiences, their "wisdom", and converts it into an all-purpose form of energy. It was created by Primacron, a scientist said to have existed since the dawn of time, who built it into his assistant, the Oracle, before they went on to create the ultimate planet robot, Unicron. Upon learning that the wisdom of the Matrix was the only thing that could match his power, Unicron rebelled against Primacron and destroyed the Oracle, who survived by transferring his being into the Matrix. He fled to the center of the galaxy and emptied the Matrix into a planet, becoming an embodiment of its wisdom and fusing with the world that would one day become Cybertron. The planet was later settled by the Quintessons, who discovered the Oracle's power and confined it within Vector Sigma, a supercomputer they controlled using a Key with which they then mechanized the planet. The aliens used Vector Sigma to manufacture intelligent slave robots who later rose up and claimed the planet for themselves, recovering the Matrix in the process. Finding it full of evil energy after years of absorbing the Quintessons' wisdom, they emptied it out and disposed of the energy.
