He loved this world and the constant new experiences so much that he deliberately ignored Ratchet's homing beacon, wanting to stay here forever. Jazz ended up on a planet that he dubbed "the Information Highway" - a constantly-morphing world with "the accumulated knowledge of countless alien cultures, condensed into some kind of sensory precipitation". They ended up attacked by Devastator and warped across space by a fold-space weapon. When the All Spark was launched, Jazz, Ratchet and Ironhide attempted to distract Megatron from pursuing it.

He only survived thanks to fellow Autobot Clocker, who was killed covering his retreat. Jazz likes "to keep his bodywork buff" by externalizing his Spark Core forcefield - in the past, that led to him almost being killed when Bonecrusher almost tore out his unprotected Spark. Jazz easily stood up for the injured Ratchet, single-handedly fighting Barricade, Bonecrusher and Blackout, and escaping. After being repaired, he and Ratchet fought together against Barricade. On board the Ark, Jazz was the first to detect the Ghost 1's presence, and was later badly damaged in a fight with the Decepticons. Jazz immediately joined Optimus in his fight for freedom when the Autobots were founded. Even so, he stayed loyal to his oaths and when ordered to arrest Optimus for treason, did so, until it became clear that they had been betrayed and marked for assassination by Megatron. Following the assault of an alien race upon the planet, when Megatron and Optimus began to part ways over the course of their species, Jazz sided with Optimus. Jazz was present when The Fallen's prison was uncovered on Cybertron. In this role he seemed to liase extensively with Optimus on the research sites of the Scientific branch of government. Jazz served a sentry role alongside Prowl operating under the command of Lord Protector Megatron.
