Transformers: The Headmasters

Initially, Takara, the Japanese producers of the Transformers toyline, imported the American Transformers cartoon series from 1984 to 1987.

When the series came to an end with the three-part miniseries "The Rebirth" in 1987, however, Takara decided to continue the series themselves, declining to import The Rebirth and instead creating a full-length 35-episode spin-off series, Transformers: The Headmasters (two additional clips episodes were produced after the fact for direct-to-video release).
