Skyfire

So I feel as though I should tell you about Skyfire, seeing as I mentioned him in my last post. In all Transformers comic series and movies, Skyfire's Alternate mode was that of an aerodynamically advanced jet.
In the G1 series, Skyfire was a scientist partnered with Starscream before the war had even started. Skyfire and Starscream were scouting and studying a distant planet, Earth, when its strange gravitational forces pulled Skyfire out of orbit and sent him crash-landing into Earth's polar ice caps. Starscream tried to find him, but Skyfire's damaged chassis was already hidden by tons of ice and snow. If you have seen Transformers (2007) this should sound familiar because the same story was used for Megatron.
Skyfire was discovered by the Decepticons billions of years later during an attempt to harness the energy of Earth's core. He was immediately brought into the fold by Starscream, who was certain that his former partner would have the same taste for warfare that he had.
Skyfire, however, felt much differently. After hearing the truth about the Decepticons from the Autobots' human ally, Spike, and having it verified later by Megatron's actions, he defected to the Autobots.
Skyfire nearly died trying to protect his new allies after he left the Decepticons. Ratchet managed to save Skyfire only to have him sacrifice himself to foil the Decepticons' plans in the Arctic.
Skyfire was brought back again later in the series and quickly became an integral part of the Autobot team, especially considering the fact that he is one of the only Autobots capable of flight.
Skyfire is larger than many Transformers, which lends him above average strength. His scientific past proves his incredible intellectual abilities which make him even more valuable to the Autobots. Unfortunately, Skyfire's greatest strength, his intellect, is also his greatest weakness. Skyfire often places his complete confidence in science and logic in untested weaponry, which sometimes fails at the worst moments.
Now that you know his real story, I will tell you that most of you know exactly who Skyfire is. In all series and movies after G1, Skyfire was renamed Jetfire, for reasons yet unknown. Most of you know him as the crotchety old "Grandpa Blackbird" in Transformers: Revenge of the Fallen.
