Terror Under the Big City

The Destrons are attracted to a city's three-layer transportation system, using Drillhorn to dig deep underground to tap into the city's electrical systems. As the Breastforce members roam around under the city, the Cybertrons pick up a distress signal and mobilize to investigate. Star Saber, the Brainmasters and the Rescue Force head into the underground to stop the Destrons, but they each encounter danger -- Star Saber meeting Deszaras, the Brainmasters meeting the Breastforce and the Rescue Force trying to free the people. Star Saber manages to defeat Deszaras and his two animal partners, forcing him to retreat with only a little amount of energy but a lot of destruction.
