Which Autobot becomes the leader in the Japanese exclusive series Transformers: Headmasters?

In the Japanese-exclusive Transformers: The Headmasters, Fortress Maximus becomes the Autobots’ giant fortress and leading commander.

The 35-episode Japanese series continues the Generation 1 story after the American cartoon’s continuity diverges. Rodimus Prime initially remains the Autobot leader, but he eventually leaves to search for a new home for the Transformers. Command then centers on Cerebros, who operates the enormous Fortress Maximus body and leads the Autobots from Athenia.

Fortress Maximus is not simply a conventional robot: in this Japanese continuity, Cerebros is a small Cybertronian Headmaster who controls a larger Transtector. When combined with the giant city-and-battle-station body, he becomes Fortress Maximus. His principal rival is Scorponok, whose own massive Transtector becomes MegaZarak.

This differs from the Western Headmasters concept, where Headmasters are Transformers partnered with Nebulon natives. It also explains why some summaries name Cerebros rather than Fortress Maximus as the commander. The quiz’s answer uses the name of the giant Autobot form and fortress.
