Meanwhile, Optimus Prime became aware of the threat of Unicron, and, realizing that the Matrix would be necessary to defeat the Chaos-Bringer, arranged for search parties to scour the cosmos for any trace of it. Longtooth was among the Autobots recruited for the search mission, and was forced for the first time to truly confront the selfishness of what he had done with the Matrix energy Prime had given him millennia before. In hopes of redemption, he loaded the energy fragment into a pod and sent it back to Optimus Prime. Whose Lifeforce Is It Anyway?Prime agonized over how to best use the Matrix energy, knowing that it had the power to revive only one of the deactivated Autobots on the Ark, and ultimately, elected to disperse it into the Earth's atmosphere to rejuvenate damage done to the ecosystem by the Transformers' warring on the planet.

However it came to be in Autobot hands, the Matrix came to be at the centre of the robots' belief system and was safeguarded by each successive generation of Autobot leaders. Upon the passing of its holder, the Matrix became a receptacle for the deceased Autobot's lifeforce, which cumulatively became known as the "Wisdom of the Ages", a storehouse of knowledge and experience stretching back to the dawn of Cybertronian history (and potentially beyond) that could be consulted by the Matrix's living wielders in times of need. The spirits of many Autobots have been seen within the Matrix, but the names of only a select few are known: The oldest entity within the Matrix is known only as "It" The Return of Optimus Prime, Part 2; following this entity, the next oldest known was Primon, who possessed the Matrix in the early days of the Cybertronian race around twelve million years ago; Prima bore it at the height of their oppression by the Quintessonsabout a million years later; Prime Nova was its wielder during the eventual rebellion against the five-faced aliens; Guardian Prime and his successor Zeta Prime carried it during the first war between the Autobots and Decepticons, before it was passed to Sentinel Prime, under whose leadership the war came to an end.[]

When the Autobots discovered that Unicron dwelt at the center of the Earth, Optimus Prime gambled that the Matrix held the power to destroy the dark god. One Shall Rise, Part 2 Led to the core of the planet by Megatron, Prime emptied the full power of the Matrix into Unicron's spark. The chaos-bringer responded by possessing Megatron in an attempt to stop him, but the Matrix generated a shield to protect Prime so that the mission could be completed, and Unicron was successfully returned to stasis. Unfortunately, in draining the Matrix of its energy, Optimus lost not merely the wisdom of the Primes, but all of his own memories since becoming a Prime. One Shall Rise, Part 3Anticipating this, Optimus had left a solution to this problem in the hands of the Autobot's human ally Jack Darby: the Key to Vector Sigma, which would allow the Matrix to be refilled, and Optimus's memory restored, via the mega-computer Vector Sigma on Cybertron. Orion Pax, Part 1 Jack and Arcee travelled to Cybertron to load the key, then returned to Earth in the midst of a battle between Orion and Megatron. Though the archivist was hesitant at first, Jack convinced him that he was in fact worthy and used the key to restore the Matrix's power and Optimus's memories. Orion Pax, Part 3[]
