In a twisted universe where almost all fictional characters ever created clash with Hank Hill in an annoying fashion. For some derpy random reason, a chest-buster alien pops out of Hank Hill's chest and has to be rebuilt...because we can rebuild him...we have the technology. Hank Hill's rebuilding (funded by Skynet) transforms who was once Hank Hill into a propane-powered machine known as...the Propainanator o_o Duh duh duuuuuuuh!!!!!!!
