Transformers: The Headmasters

Transformers: The☆Headmasters begins with Galvatron leading a new wave of Destrons into battle against Seibertron, the Destron Headmasters. The Cybertrons are rescued when the Cybertron Headmasters arrive, led by Fortress (Cerebros, head of Fortress Maximus). Fortress explains that he left Seibertron millions of years ago in search of energy and has finally returned home. He reveals that the Headmasters come from the planet Master; the human‑sized robots there built Transformer‑sized bodies, allowing them to transform into the heads of those robots, and they have now joined the Cybertron‑Destron war.
