The Transformers

based upon Hasbro and Takara's Transformers toy line. The first television series in the Transformers franchise, it depicts a war among giant robots that can transform into vehicles and other objects.

The series was produced by Marvel Productions and Sunbow Productions in association with Japanese studio Toei Animation for first-run syndication. Toei co-produced the show as the main animation studio for its first two seasons, having been tasked with creating and finalizing animation models, designing transformation schemes, storyboarding some episodes, and general direction. In the third season, Toei's involvement with the production team was reduced and the animation services were shared with the South Korean studio AKOM. The show's supervising producer (Nelson Shin) was also AKOM's founder. The fourth season was entirely animated by AKOM.

The series was supplemented by a feature film, The Transformers: The Movie (1986), taking place between the second and third seasons. This series is also popularly known as "Generation One", a term originally coined by fans in response to the re-branding of the franchise as Transformers: Generation 2 in 1992, which eventually made its way into official use. The series was later shown in reruns on Sci-Fi Channel and The Hub / Discovery Family.
