Transformers Prime: Optimus's Second in Command: Jetfire

After the death of Cliffjumper, the autobots were dealt quite the blow, both emotionally and in their numbers. On top of that air superiority is still in the decepticons favor which is still a big problem for the Autobots. But the day after the Autobots try to rescue Cliffjumper; only to find him as an undead terrorcon zombie, Ratchet picks up an autobot signal, but is perplexed to see that it is airborne. Most believe it's a trap, but Optimus believes that it is still worth investigating. As they try to do so the decepticons also pick up the signal. But the signal originator aids the Autobots in driving off the decepticons in his green cargo plane mode resembling a modified Antonov An-225. After the decepticons are dealt with, the jet hovers in front of the Autobots and then transforms into a bot that is nearly equal in height to Optimus himself. Once transformed Optimus immediately recognized who this bot was... his second in command, Jetfire.

(A/N: Yes I am using the Transformers Cybertron Jetfire for this fanfic. And he will have his cyberkey power but it will be explained differently in the story.)
