Comettor is the Mini-Con partner of Jetfire. His serious and technical outlook on things is a good balance to Jetfire's off the battlefield carefree nature. In Comettor's alternate mode, he becomes a transport vehicle with the ability to intercept and send transmissions as far as the moon. When powerlinked with Comettor, Jetfire displays upgraded targeting and extra sensory abilities as well as increased firepower.
