Transformers: The Headmasters (toyline)

The Headmasters toyline was introduced in Japan in 1987 as a continuation of the main Generation 1 toyline. Its lineup included not only the same toys released by Hasbro in the West that year, but also a variety of Japanese-exclusive toys, including Soundblaster and Twincast (redecoed and retooled versions of Soundwave and Blaster, respectively), Stepper, Artfire, and the Headmaster Warrior.

The Headmasters toyline also included the Beastformers subline, which Hasbro marketed in the West as the completely separate property Battle Beasts.
