Transformers: The Headmasters stands apart as a bold reimagining of the post-movie era, completely discarding the continuity of The Rebirth and instead continuing the story directly from the events of Season 3 with its own distinct tone and mythology. 

Centered on the concept of smaller Cybertronian partners known as Headmasters - who transform into the heads of larger Transtectors - the series expands the Transformers universe with a more technologically and politically driven narrative, introducing new factions and conflicts such as the war against Scorponok and his Decepticons. 

Beyond revisiting familiar concepts like Headmasters and Targetmasters already glimpsed in the US continuity, the series also brings to life several toyline characters that never appeared in the American cartoon.
