The Pastmaster is wreaking havoc on Megakat Bridge when the SWAT Kats arrive to stop him. The Pastmaster anticipated this and opens up a time vortex and forces the SWAT Kats and himself into it. They re-emerge in a futuristic city made up almost entirely of metal, patrolled exclusively by robots where kats are forced to work in labor camps. On an enormous Jumbotron-like screen in the center of the city, the Metallikats appear and inform the SWAT Kats that in this future, they are the rulers of “Metallikat City.”
