Fiction

TransTech

One time on Antares 3, Jackpot and Hubcap were involved in a battle against some Decepticons. After being winged by a Terrorcon, Hubcap created a smokescreen by revving his engine heavily, allowing the pair to escape. Years later, after they were transported to Axiom Nexus, Jackpot reminded Hubcap of the incident and they used the same tactic to bail on an interrogation at the hands of the Security Administration.
