Rex along with Axel were tasked with dealing with alien space pirate Kiddlaw. Rex possessed a spacecraft known as the Hi-Lo which could manipulate cosmic radiation to fly through the vacuum of space, while Joan and Axel mostly assisted him. All three had advanced weaponry at their disposal to utilize during their various missions. Through a series of adventures, Cosmos became betrothed to the Queen of Fortune, but inevitably it was Kiddlaw who dealt with the trio and Joan's father by gassing them. As they were never seen again, it is presumed they perished during this defeat.
