Headmasters starts with Galvatron leading a new batch of Destrons to wage war on Seibertron, the Destron Headmasters. The Cybertrons are rescued by the arrival of the Cybertron Headmasters, led by Fortress (Cerebros, the head of Fortress Maximus). It is revealed that Fortress left Seibertron millions of years ago in search of energy, and have finally managed to come home. He explains that the Headmasters are from a planet called Master; the human-sized robots who live there built themselves Transformers-sized bodies.

Despite his incredible fighting skills, courage and unmatched talent for improvisation on the battlefield, Ultra Magnus is most comfortable when carrying out orders, and is naturally at ease if the Autobot Matrix of Leadership should ever find itself placed upon him. In Ultra Magnus' mind, he is a commander of the wreckers, and his reluctance to change that will see to it that he expends all options before accepting the idea that he is required to lead. As a leader, Magnus would be resolute, fair and courageous, ever-ready to sacrifice himself for the greater good of his companions and mission, and unyielding in preparation for protection of those under his command. Although not interested in overall command, Ultra Magnus was the City Commander for Autobot City in The Transformers: The Movie, and his toy also featured him in the role of City Commander (a title also held by his original opposite number, the Decepticon leader Galvatron), which indicates that he at least is willing to accept a leadership role in a smaller capacity rather than as supreme commander, a role filled by both Optimus Prime and later Rodimus Prime. Ultra Magnus is armed with missile launchers capable of hitting a target 30 miles away, and transforms into a car carrier able to transport his fellow Autobot troops.
