Jetfire is probably the best second-in-command Optimus Prime could conceivably have. Jetfire is more than a yes-man; he's the crucial link between Prime's role-necessitated distance and his troops. Though professional and businesslike, Jetfire infuses his interactions with a down-to-earth friendliness. And where Optimus Prime is cautious, Jetfire is more prone to tempered bursts of gusto and bravado. While Optimus Prime is your leader who's your leader, Jetfire is your leader who's your friend. Because of this, Jetfire is very popular among the Autobots.
