The Transformers toyline and animated series were inspired by the Japanese toyline, "Microman" (an Eastern descendant of the 12-inch G.I. Joe action figure series) by Takara. In 1980, the "Microman" spin-off, "Diaclone", was released, featuring inch-tall humanoid figures able to sit in the drivers' seats of scale model vehicles, which could transform into humanoid robot bodies the drivers piloted. Later still, in 1983, a "Microman" sub-line, "MicroChange" was introduced, featuring "actual size" items that transformed into robots, such as microcassettes, guns and toy cars. "Diaclone" and "MicroChange" toys were subsequently discovered at the 1983 Tokyo Toy Fair by Hasbro toy company product developer Henry Orenstein, who presented the concept to Hasbro's head of R&D, George Dunsay. Enthusiastic about the product, it was decided to release toys from both "Diaclone" and "MicroChange" as one toyline for their markets, although there were eventual changes to the color schemes from the original toys to match the new series.
