Jetfire
Japanese: In the many stories of Jetfire (who was referred to as Skyfire in the TV series), told through the numerous Generation 1 continuities, there is one constant aspect—an early affiliation with the Decepticons, which has served only to convince him to side with the Autobots.
Repaired by Ratchet, he joined the Autobots 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.
[5] A short time later, however, Skyfire was recovered by Wheeljack and Sideswipe, and immediately participated in an attack on the Decepticons in Peru,[6] where the evil robots were once again attempting to use the Earth's core energy for their own means.
Grimlock in particular bore a fierce grudge against him for an unspecified incident involving a mind-controlling cerebro-shell and was perfectly ready to believe that he had betrayed the Autobots when he arranged a meeting with current Decepticon leader Shockwave.
Jetfire was among the Transformers kidnapped by the ancient Cybertronian called the Fallen, who planned to use the genetic potential in his spark to awaken Primus, but he was freed by Grimlock, putting the grudge to rest.
Prime and Megatron subsequently returned to Cybertron, but when they and their elite crews were lost aboard the Ark, Jetfire was part of a mission to find them, along with Omega Supreme and the Micromasters Countdown and Groundshaker.
When a lead emerged in the form of a beacon from the Sol system, Jetfire and Omega split off from the team (who went on to investigate Decepticon attacks on other planets) and headed off after the signal.
Before Jetfire could bring Omega back online, however, their ship was attacked by Scourge and crashed in the Arctic, where shrapnel from it killed a pod of whales.
Upon returning from a trip to Cybertron with fresh plans of conquest, Starscream thawed Jetfire out to aid in repelling the maniacal Sunstorm, a clone of himself that Shockwave had created, but which had gone insane.
In the Fun Publications Classicverse stories Optimus Prime has returned to Earth commanding Bumblebee, Cliffjumper, Grimlock, Jetfire, Mirage and Rodimus (formerly Hot Rod).
[11] Jetfire was presented as a technician and computer expert, who ran field ops during the battle of Thunderhead Pass trying to find a weakness in Thunderwing that could allow the Autobot-Decepticon army to defeat him.
Jetfire was constructed by Shockwave on Earth to be one of his new Decepticon troops, given life through the powers of the Creation Matrix, tapped from the captive Autobot leader, Optimus Prime.
Still bearing the Decepticon insignia Shockwave had stamped him with, Jetfire was not trusted by Ironhide until he saved him from the deranged Slag, proving his Autobot loyalty.
The Robots in Disguise Classic line appeared in a simple Flash-based video game on the Hasbro website called Transformers Battle Circuit.
The friendly nature that keeps him popular amongst the Autobots hides a strong sense of intelligent judgment that has saved his team from numerous predicaments and means that he will even speak up and tell Prime that he is wrong to his face.
When Thrust arranged the next Decepticon attack on the Autobots, Jetfire once again proved to be the monkey wrench in his plan when he and Optimus Prime revealed their ability to combine, once again foiling the villain's schemes.
Despite his external changes, however, Jetfire remained consistent in personality and outlook, always ready with a witty remark to keep the mood light even in the middle of a pitched battle.
The resultant battle saw Unicron's body destroyed, but his spark endured and possessed Megatron — now Galvatron - who grew to colossal size.
To combat the giant villain, Jetfire, and the Autobots took their Spark of Combination to the ultimate extreme, transforming their bodies into pure energy and merging with Optimus Prime, enlarging him to similar proportions and allowing him to battle Galvatron directly.
His relaxation was brought to an end, however, when Primus's energon sun collapsed in on itself, forming a gigantic black hole that threatened the safety of Cybertron.
The Terrorcon threat underwent sudden, horrific multiplication when they were cloned through Unicron's power, and massive swarms of them assaulted key cities across Earth.
IDW's Transformers Collectors Club exclusive comic story, "Revelations Part 6", is set after the defeat of Galvatron but before Optimus Prime's mission to start a new Space Bridge project.
In this story the Autobots from the Fun Publications stories (Robots in Disguise Optimus Prime, Ultra Magnus, Sentinel Maximus, Downshift, Perceptor, Alpha Trion, Over-Run, Anti-Blaze, Checkpoint, and Scythe) meet the Autobots from the animated series (Cybertron Optimus Prime, Jetfire, Override, Scattorshot, Red Alert, Hot Shot, Lori, Bud, and Coby Hansen) and thank each other and remembering those who were lost in the battles.
[32] In Defiance issue #4, which is a prequel to the movie series, a younger Jetfire is seen in his Cybertronian mode, traveling the galaxy for star-orbited planets, in a flashback told by the Fallen to Megatron.
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.
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.
Jetfire is a playable character in the PS2 and Wii versions of the Transformers: Revenge of the Fallen video game and is in the new downloadable content pack for the PS3 and Xbox 360.
They reluctantly followed Sentinel's orders to organize a strike against Omega Supreme (containing Megatron, Starscream, and Lugnut), who had recently transwarped above Cybertron.
Jetfire is one of the playable Autobots in the 2010 video game Transformers: War for Cybertron, and speaks with an English accent (similar to his film incarnation).
He also tries to warn Megatron about the deadly effects of dark energon, but his cries fall on deaf ears, as the Decepticon leader immerses himself in it, becoming more powerful.
