Skyfire

Jetfire is the name of several fictional characters from the Transformers universes. He is nearly always depicted as an Autobot with jet or space shuttle alternate mode.

Transformers: Generation 1
In the many stories of Jetfire (who was referred to as Skyfire in the TV series, known in Italy as Aquila) told through the numerous Generation 1 continuities, there is one constant aspect — an early alliance with the Decepticons, which has served only to convince him to side with the Autobots. Jetfire's dedication to the Autobot cause is matched only by his devotion to scientific and technological advancement — this, he believes, is the only way in which victory over the Decepticons can be achieved. It is this overriding belief that tempers his bravado in battle, but nevertheless, he is often one of the most eager Autobots to plunge into combat, and his position as one of the fastest usually means he is the first to do so. Jetfire is created from the same mold as the VF-1S Super Valkyrie from the Macross series (see Toys), including the VF-1S's gunpod, which is described as a laser on Jetfire's technical specifications.[1]

Animated series
In the animated series, Jetfire was called Skyfire, for reasons discussed below.

On Cybertron before the war, Jet Fire was a scientist and explorer working with Starscream. Together, they investigated an uncharted planet (Jacinto), where they failed to find any signs of intelligent life. Jet Fire wished to scrutinize the planet further, and moving in close enough to the planet, a polar wind storm swept him up and buried him beneath the Arctic ice. Starscream searched for his friend, but was unable to locate him and returned to Cybertron alone.

Millions of years later, in 1984, the Decepticons excavated the frozen Skyfire while draining heat energy from the Earth's core and reactivated him. Reunited with his old friend, Starscream, Skyfire joined the Decepticon ranks. When the Autobots arrived, Skyfire engaged in battle with them, but then saved the Autobots' human allies Sparkplug and Spike Witwicky when they became stranded on an ice floe. Naively, he took the two to Megatron under the impression that he and the other Decepticons were good, but when Megatron took them as prisoners, Skyfire started to question his allegiance. When Starscream ordered him to destroy the captured Autobot search party, he refused, and Starscream turned his weapons on him, leaving him heavily damaged. Repaired by Ratchet, he joined the Autobot side and engaged in a dogfight with Starscream which ended when he sacrificed himself to stop the core drain, burying himself in ice once again in the process.

A short time later, however, Skyfire was recovered by Wheeljack and Sideswipe, and immediately participated in an attack on the Decepticons in Peru, where the antagonists were once again attempting to use the Earth's core energy for their own means. Skyfire was almost permitted to destroy the villains' new weapon by Thundercracker, but was then blasted by Starscream and repaired with some difficulty by Spike.

Skyfire would go on to make semi-regular appearances in the immediate future, helping the Autobots evacuate their base when the volcano it was embedded in became active, and flying a squad of troops to battle the Insecticons.[2]

Transformers: Revenge of the Fallen
In a USA Today online fan poll following the release of the 2007 live-action film, Jetfire was one of the 10 Transformers that the fans wanted in the sequel, coming in 4th with 11% of the votes.[20]

Jetfire appears in Transformers: Revenge of the Fallen and transforms into a Lockheed SR-71 Blackbird.[21] He is portrayed as a Decepticon who becomes an Autobot because he did not believe in all the destruction and violence the Decepticons brought. Originally serving the Fallen, Jetfire is one of the few Transformers to remain on Earth since the dawn of humanity.

According to the biography and statistics published on the Hasbro web site, Jetfire is 50 feet tall and his main weapon is his particle beam cannon.[19] In the film, he also wields an arm mounted rocket launcher and a battleaxe. As a comical emphasis on his old age, he carries a walking stick that transforms into the front landing gear of his jet mode.In the film he can project hologram clips from the palm of his left hand similar to how Optimus Prime did in the 2007 film though his eyes

Movie plot
Jetfire talking to Sam (Shia LaBeouf), Simmons (John Turturro), Leo (Ramon Rodriguez) and Mikaela (Megan Fox)Jetfire is found by Sam Witwicky, Mikaela Banes and Seymour Simmons at the Steven F. Udvar-Hazy Center, an annex of the National Air and Space Museum, after Wheelie pinpoints the general location of the ancient Seeker. Sam reactivates him with an Allspark fragment, waking him up from stasis lock. After a misunderstanding when the humans saw his Decepticon insignia, Jetfire activates a Space Bridge to teleport Sam and his friends to Egypt, explaining to them the origin of the Primes (who he seems to have a certain type of respect for) and the Matrix of Leadership. Learning of Optimus Prime's existence and death, Jetfire sends them to find the Matrix, which he speculates can be used to revive Optimus (Although it could also be used to power the Fallen's technology). He demonstrates his immense power as an ancient Seeker when he arrives late in the final battle at the Giza Necropolis, and cleaves his battleaxe clear through Mixmasterand stomps off his head, killing him and saving the human forces nearby, although soon after he is attacked and mortally wounded byScorponok but manages to easily crush his attacker after recovering from the surprise attack (saying he is "too old for this crap"). Eventually, as ordered, Sam revives Optimus with the Matrix (much to Jetfire's relief) right before the Fallen steals the Matrix to activate the Sun Harvester. Seeing that there might be hope with a living Prime, Jetfire then acknowledges that he had never done anything "worth doing" until he had fought on behalf of the Autobots and sacrifices himself by tearing out his spark in order to allow for Optimus to use his parts to engage the Fallen. Thanks to Jetfire's sacrifice, Optimus proves to be more than a match for Megatron and the Fallen combined and defeats Megatron before killing the Fallen. Optimus then discards Jetfire's parts and its unknown what happened to them after that.
