Jazz remains one of the more popular and well-remembered characters from the original series. Because of problems with trademarking the name Jazz, some later releases of Jazz are called Autobot Jazz.
In the episode "Attack of the Autobots", he and Bumblebee were the only Autobots to avoid being brainwashed. But thanks to his new sound system and Sparkplug's attitude exchanger, the Autobots were able to be cured and the Decepticon's plans were foiled.
In the episode "The God Gambit", Cosmos collected data in space on a potential new power source, but was attacked by Astrotrain, Thrust and Starscream. Crashing on the Saturn's moon Titan, the local priests worshiped the Decepticons as "Sky Gods", but rebels were able to reactivate Cosmos and call for aid from the Autobots. Optimus Prime sent Omega Supreme along with Perceptor and Jazz. Astrotrain set himself up as the chief god of the moon and forced the natives to gather energy crystals. The trip to Titan drained Omega of most of his energy, but Perceptor and Jazz were able to gather enough crystals to reactivate Omega and defeat the three Decepticons. Vowing to not let the Autobots gain the crystals, Astrotrain set up a chain reaction destroying them. The Autobots aided the natives to escape the explosion and helped them settle in another area of the moon.
In the episode "Prime Target", the big game hunter Lord Cholmondeley captured a secret Soviet jet, leading to panic of possibly war. Cholmondeley then set his sights on the ultimate trophy, the head of Optimus Prime. In order to lure Optimus, in Cholmondeley captured the Autobots Tracks, Bumblebee, Jazz, Beachcomber, Grapple, Blaster and Inferno. Windcharger and Huffer were able to avoid being trapped. When Cosmos learned of the location Cholmondeley was keeping the captured Autobots, Optimus Prime accepted Cholmondeley's challenge to meet him alone. Although interrupted by Astrotrain and Blitzwing's attempt to ally the Decepticons with Cholmondeley, Optimus defeated the big game hunter and freed the Autobots. Cholmondeley and the stolen jet were given over to the Soviets by the Autobots as punishment for his actions.
When Starscream was exiled from the Decepticons and created the Combaticons (in "Starscream's Brigade") his first act was to capture the Autobots Cliffjumper and Jazz during the unveiling of a statue of Optimus Prime.
Towards the end of 1985, Jazz was among the team of five Autobots who disguised themselves as the Stunticons in "Masquerade". (Jazz, a Porsche 935, was made to resemble Dead End, the Stunticon Porsche 928.) Penetrating the Decepticons' camp, the Autobots ran into trouble when the real Stunticons arrived, trying to prove their identities by forming Menasor. With a combination of Windcharger's magnetic powers and Mirage's illusion-creating ability, the Autobots were able to appear as Menasor too. Though the deception was soon revealed, they were still able to thwart the Decepticons' plans.
In The Transformers: The Movie, set in the year 2005, Jazz was assigned to Moonbase One along with Cliffjumper. Jazz was responsible for monitoring Decepticon activity on Cybertron using the base as a secret staging ground for planning the liberation of Cybertron. After the Autobot City invasion of Earth, Moonbase One came under attack by the planet eater, Unicron. Jazz radioed to Earth for assistance and his faint signal was received by the Autobot Blaster who relayed the distress signal to Ultra Magnus. Jazz and Cliffjumper attempted to escape, however the shuttle could not achieve escape velocity and was swallowed by Unicron. During the assault on Unicron lead by Hot Rod and Ultra Magnus, Daniel Witwicky encountered a smelting pit inside Unicron, where other Transformer-like beings were being sent to be melted into a liquid substance. Jazz, Cliffjumper, Bumblebee and Spike were about to be cast into the pit but Daniel managed to rescue them in the nick of time. Jazz and the others escaped Unicron before the planet-sized Transformer exploded from the effects of the Autobot Matrix.
During the time between the movie's release and the start of Season 3 of the TV show, Jazz's voice actor, Scatman Crothers died. The movie release was the last time that Jazz spoke. However, Jazz made minor cameos throughout the season in the episodes "Five Faces of Darkness" where he competed in a race and fought alongside Perceptor and Rodimus Prime.
In the episode "Dark Awakening", he briefly stood beside the re-incarnated Optimus Prime. In the episode "Forever is a Long Time Coming" he appeared in another race and in the episode "Call of the Primitives", he was seen for the final time. It is assumed that Jazz was left to patrol Cybertron and was around to witness its new golden age.
After the animated series ended in the U.S., Jazz appeared in animated form in the commercials for the Classic Pretenders and Action Masters.
Jazz passionately opposed Prowl's idea to use the Creation Matrix to create dedicated war machines to crush the Decepticons; he labelled such creations abominations. This ethically questionable move was staved off and Jazz continued to serve the Autobots well on Earth. Following the arrival of Galvatron in Target: 2006, he was captured and his mind viciously reprogrammed to make him a zombie servant. This left him incapacitated for a long while. He was eventually repaired, but soon met deactivation once more against the Underbase-powered Starscream.
Jazz's body was seen among the deactivated Autobots Ratchet was doing his best to revive in Transformers #56, "Back from the Dead".
To stop Megatron, Autobot medic Ratchet later restored Jazz as a Classic Pretender, along with Grimlock and Bumblebee. They remained on Cybertron and were an inspiration to the Autobot rebels, leading multiple raids on the Decepticons and also fighting several of the demons that lived beneath Cybertron. When a return trip to Earth was interrupted, the Classic Pretenders found themselves in front of the sleeping Primus and, after battling the Mayhem Attack Squad, witnessed him awaken. Jazz would go on a last mission as a Classic Pretender in the "Matrix Quest", heading to the moon of Vsqz to retrieve the lost Matrix, though Thunderwing got to it first. He was later among the united Autobot and Decepticon forces who opposed Unicron's assault on the planet Cybertron in 1991 (Transformers #75). Immediately prior to this, Jazz was seen as one of the few surviving Autobots in the alternate 2009 seen in the story "Rhythms of Darkness". Here he fought Galvatron to give Spike time to attach the American flag to the Deception stronghold in New York and persuade the European Coalition to call off their nuclear attack. Jazz was saved from death by the arrival of Hook, Line and Sinker, who forcibly transported Galvatron back to the "present" of the regular timeline. He briefly reappeared during the battle on the planet Ethos in the Generation 2 comic.
Jazz was also one of the main Autobots in the Earthforce unit of Marvel U.K.'s Earthforce stories. The annual story "The Magnificent Six" revealed that four million years ago, Jazz was teamed with Inferno, Ironhide, Wheeljack and Sunstreaker and had been tortured by the sadistic Decepticon Megadeath in the Stanix region. He and the others faced Megadeath once again in the present and defeated him.
Jazz would appear in the U.K. Marvel comic issue #234, "Prime's Rib!" This story is set in the near future, 1995, where Optimus Prime, Jazz and Hot Rod introduce the latest Autobot, Arcee, to the human feminists. She was met with displeasure by the humans, being called a token female and disliked for her pink color. They were then attacked by Shockwave, Fangry, Horri-Bull and Squeezeplay, who thought the Autobot would be unvieling a new weapon. The Autobots fought off the Decepticons, who escaped, but nothing seemed to please the human feminists.
When civil war broke out on the planet Cybertron between the Autobots and Decepticon factions, Jazz joined the Autobot cause. After Decepticon leader Megatron killed the Autobot leader Sentinel Prime, a new Autobot leader was chosen by the Council of the Ancients. Jazz was present when Optronix was given the Matrix and reformatted into Optimus Prime. Three Decepticon assassins attempted to kill Optimus, but were unsuccessful. Optimus then ordered a planet-wide evacuation of Cybertron (Transformers: The War Within #1). When Shockwave led a force of Decepticons against the Autobot capitol of Iacon, Jazz was among the Autobots who defended the capitol (War Within #3).
When Megatron and Optimus Prime disappeared in an accident with a space bridge, the Autobot and Decepticon forces splintered into smaller factions. Jazz stayed with the Autobots under the leadership of Prowl. Learning that the Decepticons were testing a new mobile command base at the Praetorus Wharf, Prowl lead Cliffjumper, Gears, Jazz, Skids and Sideswipe to investigate. What they discovered was Trypticon (Transformers: The War Within - The Dark Ages #3). Only Shockwave calling the giant away to combat the Fallen saved them. When the Fallen attacked the Autobot base in order to capture Blitzwing, Jazz was among the Autobots who futilely tried to stop him.
Jazz was among the Autobots who followed Optimus Prime on his mission on board the Ark. They were attacked by Megatron's ship, the Nemesis and crash landed on Earth, where all on board were preserved in emergency stasis. In 1984, a volcanic eruption awakened the Ark's computer, Teletran-1, and it repaired all on board. It reformatted Jazz in the form of an Earth car.
Eventually, the combined forces of the Autobots on Earth and their human allies were able to capture the Decepticons. A ship called the Ark II was built to take the Cybertronians back to Cybertron, along with some human companions, but the ship exploded shortly after takeoff. The human allies were killed, but the Cybertronians were lost in the ocean, again in statis lock.
In the frozen Arctic, a man named Lazarus began resurrecting the lost Transformers and planned to control these giant metal warriors and sell their services in war to the highest bidder. The American government had recovered Optimus Prime and used him to rescue several Autobots from their Arctic prison, including Jazz. After they had recovered their friends from Lazarus, Jazz led a group of Autobots to stop the spread of Megatron's deadly virus in the Canadian Northwest territories.
As the Autobot and Decepticon war continued on Earth, an escape pod beacon drew their conflict to the Arctic. The pod contained the rogue Decepticon Scourge. The battle between the Autobots and Decepticons ceased long enough to find the new Cybertronian commander, Shockwave, had arrived in pursuit of Scourge and to arrest Optimus Prime and Megatron. Jazz was ordered by Prime to remain on Earth with a small Autobot task force.
When Ultra Magnus came to Earth claiming that the Earth-based Autobots were Cybertronian criminals, Optimus Prime surrendered and with the majority of Autobots returned to Cybertron. Jazz was left in charge of the Ark, with Brawn, Ratchet, Sideswipe, Sunstreaker, Wheeljack and Windcharger assigned to him.
Returning to Earth with the Combaticons, Starscream reformatted them into Earth-style vehicles and attacked the Autobots remaining on Earth. Forming Bruticus, the Combaticons defeated Jazz, Sideswipe, Sunstreaker, Wheeljack and Windcharger. Only Ratchet and Brawn escaped capture, but as they made their way back to the Ark, they discovered its defenses on automatic, and had to fight their way inside. Bruticus followed them and Ratchet had to destroy the Ark in failed attempt to destroy Bruticus. Starscream eventually captured Ratchet and Brawn, right as an Autobot shuttle and Sunstorm arrived on Earth (Transformers: Generation One vol. III #1).
Jazz, Sideswipe and Sunstreaker were repaired by the Earth Defense Command. In return, Jazz commanded Sunstreaker, Sideswipe and Bumper in investigating the Insecticons for the Earth Defense Command. Eventually they rejoined Windcharger and Wheeljack,and all rejoined Ratchet on board the Autobot ship Orion (Transformers: Generation One vol. III #9).
Landing in Alaska, Jazz and the other Autobots met Prowl's team back from Cybertron. They were shown the site of construction for the new Autobot City (Transformers: Generation One vol. III #10). Brawn, Grapple, Hoist, Jazz, Omega Supreme, Prowl, Red Alert, Sideswipe and Sunstreaker were among the Autobots who continued work on Autobot City (Transformers: Generation One vol. III #13).
In IDW Publishing's The Transformers: Infiltration mini-series, Jazz is part of an infiltration unit consisting of Ratchet, Ironhide, Wheeljack, Bumblebee and Sunstreaker, led by Prowl. He has not played a major role thus far, other than to accompany the other Autobots to the Decepticon base to watch the duel between Megatron and a super-powered Starscream, saving Bumblebee from Runabout at one point.
In the follow-up series, The Transformers: Escalation, after the supposed demise of Sunstreaker, Jazz and Wheeljack tracked down his body — only to be temporarily disabled by the advanced weaponry of the Machination (although Jazz' pride took more of a dent). Since then he has accompanied Optimus Prime to Brasnya to track down Megatron and his human facsimile — only to wind up in battle with Skywarp and Astrotrain. He and Wheeljack managed to put Skywarp to flight, but he promised to return with reinforcements. They then confronted Megatron (who had nearly killed Optimus Prime). On Prime's orders, they focused fire on Megatron long enough for Prime to recover and drive off the Decepticon leader, although they were prevented from dealing a killing blow by the appearance of Skywarp and Thundercracker.
A few prototypes of the toy in package were made, and have sold for over $1300 in auction.
Jazz is the smallest of the Autobots. Michael Bay stated in an early interview that Jazz stands 13 feet tall , however the scale of his Deluxe toy suggests he would stand closer to 15 feet tall. This is confirmed by his profile in the second issue of the Transformers U.K. Magazine, where it is stated he stands 15 feet 7 inches tall, weighs 1.8 tons and has a maximum speed of 400 miles per hour. The official guide to the Transformers video game also says he's 15 feet tall. Jazz died near the end af the movie. Megatron picked him up, and Jazz said " You wanna piece of me?" Megatron then replied with "No, I want two." Megatron then ripped Jazz in half.
The vehicles used for Bumblebee, Ironhide, Jazz and Ratchet were put on display by General Motors at the 2007 Detroit River Walk Festival a little over a week before the U.S. release of the film.
Jazz appeared in issue #6 of the Titan Transformers magazine. Clocker and Jazz were being pursued by Bonecrusher, with Jazz half-dead due to not protecting his Spark Core properly - he would've been fully dead if Clocker hadn't saved him. Clocker ordered him to flee while he fought the enemy - the condition Jazz was in, "you're more hindrance than help to me". Clocker's shots barely affected Bonecrusher and by the time reinforcements arrived, he had been killed.
The Autobots then return to Sam's house and retrieve the glasses whilst attempting to hide from Sam's parents, which results in his mother's and father's prized gardens being destroyed by Prime's massive feet and Ratchet (Jazz in the comic adaptation) cutting off the neighborhood's power after accidentally colliding with an electric transformer (which they blame on an earthquake). Unfortunately, that same evening a secret government organization, Sector 7, arrests Sam Witwicky, Mikaela Banes, and captures Bumblebee. As the four remaining Autobots debated their next move after Bumblebee's capture the previous night, Jazz showed the most concern for Bumblebee.
Jazz plays a large role in the final battle: when Bumblebee is unable to fight, he provides cover despite being outnumbered three to one. He fights against Brawl in the final battle along with Ironhide and Ratchet. He then fights against the Decepticon leader, Megatron, in the final battle. He orders Ironhide and Ratchet to fall back, however he decides to stand his ground in order to protect the humans running away. Despite his efforts on trying to injure Megatron, he is carried atop a tall building and viciously torn in half by the Decepticon leader after mocking him (making the mistake of saying "You want a piece of me!?"). Despite Ironhide and Ratchet's best efforts, Jazz does not survive. After Megatron's death by Sam, Prime and the remaining Autobots mourn for Jazz. The film does not make it known what Optimus does with the remains of Jazz that he held in his arms. The screenwriters chose Jazz to die as they felt he was the most likeable character after Optimus and Bumblebee, but they felt a tight budget meant not enough screentime was spent on making his death emotionally effective.
Darius McCrary, Jazz's voice actor, also hinted at the film's L.A. premiere that Jazz might return. However, director Michael Bay later stated on his forum that Jazz will stay dead (although he himself has stated that he will intentionally leak false information about the sequel). A silver Pontiac Solstice GXP has been spotted on the set of Transformers 2, possibly hinting that Jazz will return, Roberto Orci has reported that jazz his not returning
In the mobile phone version of Transformers: The Game, Jazz was brought back by Ratchet using the last piece of the Allspark. In the console versions of Transformers: The Game, Jazz is killed by Devastator and not by Megatron in the Autobot storyline. In the Decepticon storyline, he is killed by Barricade.

According to his tech specs, Jazz and his brother Ricochet serve as Optimus Prime's powerful and merciless bodyguards.
Jazz's speech mannerisms are based upon those of Mr. T.
Jazz appeared as a member of Optimus Prime's forces in the "Shattered Glass" story.
