High Quality Content by WIKIPEDIA articles! In the fictional universe of the first Transformers animated series, Vector Sigma is the "mega-computer" that gives sentience ("Sparks" in later parlance) to non-sentient robots, and is used by the Quintessons to endow their robotic creations with the true life that eventually leads to their rebellion. Vector Sigma attests that "before Cybertron was, I was." Subsequent fictions, such as Dreamwave`s Transformers, would establish that Vector Sigma is a mainframe used by Primus, the creator god of the Transformers.
