After the Autobots and Decepticons Civil War ended, the Martos moved from Philadelphia to the small town of Witwicky, Pennsylvania. There, young Robbie and Mo Marto witnessed the birth of a new type of Transformers called the Terran, and they established a connection with them. Terrans are now being adopted into a family where they work with their children to protect their new lives and find their place in the world.
