In the many stories of Jetfire 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, including the VF-1S's gunpod, which is described as a laser on Jetfire's technical specifications.
