Transformers: The Headmasters
Transformers: The Headmasters (トランスフォーマー ザ★ヘッドマスターズ, Toransufōmā: Za Heddomasutāzu) is a Japanese anime television series that is a part of the Transformers franchise. It aired from July 1987 to March 1988, and its 17:00-17:30 timeslot was used to broadcast Mashin Hero Wataru at the end of its broadcast.
Development
Inititally, Takara, the Japanese producers of the Transformers toyline, imported the American Transformers cartoon series from 1985 to 1986. 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). Supplanting The Rebirth's position in Japanese continuity, The Headmasters occurred one year after The Return of Optimus Prime, introducing the titular characters to the Transformers universe in a different way. Whereas in western fiction, the Headmasters result from the merging of a Transformer with an organic alien being from the planet Nebulos, the Headmasters of the Japanese series are a group of small Cybertronians who departed the planet millions of years ago and crash-landed on the inhospitable planet Master. To survive its harsh climate, a select few Cybertronians constructed larger bodies called "Transtectors", to which they connected as the heads.
