Vector Sigma, is an ancient and incredibly powerful multiversal super computer which exists across many (conceivably all, though this is speculative) universes. Collectively these multiversal nodes are networked together as the "Vector Sigma Gestalt".

Described as the "mega-computer" which gave all Transformers life, Vector Sigma resides in a spherical chamber deep within the planet Cybertron.
In 1985, seeking to combat the Autobots' rule of the roads, Megatron created the Stunticons and brought them to Cybertron with the intent of having Vector Sigma program them with true cybernetic personalities. Requiring Vector Sigma's activation key to bring the computer online, he stole it from Alpha Trion and successfully completed his plan. In retaliation, Optimus Prime constructed his own new team, the Aerialbots, but Megatron had already returned to Earth with the key still in his clutches, leaving the Autobots unable to reactivate Vector Sigma. As a first-generation product of Vector Sigma, Alpha Trion shared the mega-computer's computation matrix, and sacrificed himself by merging his lifeforce with it. This action reactivated the computer long enough for Optimus Prime to instruct it to program the Aerialbots with life.
Shortly thereafter, it was revealed that the key possessed another power—the bizarre ability to generate an energy beam that "de-energizes" organic matter, transforming it into lifeless metal. Megatron attempted to use this power to turn Earth into a new Cybertron, but his plans were thwarted and the key destroyed.
In 2007, Optimus Prime used the shell of the emptied Matrix of Leadership to reactivate Vector Sigma, allowing him to communicate with Alpha Trion in order to obtain information on the Plasma Energy Chamber. Alpha Trion indicated that the recent conflict that had erupted around the Chamber had, in fact, been engineered by Vector Sigma as a means of bringing about a new Golden Age of Cybertron. The plan ultimately succeeded when the chamber's energies were released, forcing Earth's sun to go supernova, only for the excess solar energy to be rerouted into Vector Sigma by Spike Witwicky and the Autobots' Nebulan allies, thereby re-energizing the planet.

The Oracle was a computer similar to Vector Sigma. It is revealed that the Oracle is, indeed, the same thing as Vector Sigma. Or, at the least, that the Oracle is some sort of shell, wrapper, or interface to Vector Sigma.
The Oracle was a shell program constructed by the Quintessons to limit the potency of Vector Sigma. Occasionally, Vector Sigma was able to break through the Oracle and issue commands. At other times, the Oracle's messages were lies planted by the Quintessons or whoever else may have gained control of the shell program. The Quintesson Al-Badur described Vector Sigma itself as "the ultimate physical embodiment" of Primus.
Vector Sigma was the internal computer of Primus, which he used to analyze what was happening in the universe via information gained from the Sonic Canyons. After taking control of Cybertron, Shockwave attempted to access Vector Sigma and download its information, but concluded that he needed the Matrix of Leadership to initiate an uplink. Capturing Optimus Prime, he forcibly removed the Matrix from the Autobot leader and initiated a complete download. However, the information was so great that it overwhelmed Shockwave's multiple secondary computers, spilling into whatever available memory it could find, including the as yet-to-be activated Sunstorm.
Robots in Disguise
The Robots in Disguise cartoon was set in a new continuity, but featured many references or throwbacks to previous series. One example is that Optimus Prime says he was chosen by Vector Sigma to carry the Matrix of Leadership and lead the Autobots.
The AllSpark has the same shape and powers of Vector Sigma, but not the same color.
Vector Sigma is a data track preserved by the great Autobot historian Alpha Trion.
Jack Darby was entrusted with the Key to Vector Sigma by Optimus Prime before his fight with Unicron. After Optimus Prime lost his memory which regressed back to his time of being Orion Pax, Jack and Arcee used the Decepticons' Space Bridge to travel to Cybertron so that they can get to Vector Sigma and power up the Key to Vector Sigma in order to recharge the Key to Vector Sigma. Of course when on their way to Vector Sigma, Jack and Arcee were attacked by an Insecticon which Arcee fought while Jack headed towards Vector Sigma. When Jack arrived at where Vector Sigma is, he activated Vector Sigma and placed the key into it. While the downloading of the knowledge into the key was being done, there were some attacks by Scraplets. To keep Vector Sigma working, Jack threw a Scraplet towards the Insecticon causing the other Scraplets to chew upon the Insecticon while Vector Sigma finishes it's job. Once the job is done, Jack and Arcee return to Earth to see if the Key to Vector Sigma will help regain Optimus Prime's memories.
- A hollow plastic Vector Sigma, packaged with a removable Circuit Key and a clear "hovering effect" display stand, was a special souvenir item offered exclusively at BotCon 2007.
- In Prime cartoon, Vector Sigma appears to be a cross between its G1 and Beast Machines representations. It appears a large glowing mass encircled by two rings that constantly rotate around it. Although normally the surface of the mass cannot be seen due to its bright glow, when viewed through the Scraplet's visual range it appears to be a sphere with the same triangular patterns on it as seen in both G1 and Beast Machines.
