The Transformers is an American animated television series depicting a war between giant robots who could transform into vehicles, animals, and other objects. Written and recorded in America, the series was animated in Japan and South Korea. The entire series was based upon the line of transforming toys originally created by Japanese toy manufacturer Takara, which were developed into the Transformers line by American company Hasbro.

In Japan, the series was called Tatakae! Cho Robot Seimeitai Transformer - lit. "Fight! Super Robot Life Form Transformer") for Seasons 1 and 2, and Transformers 2010 for Season 3. Following the conclusion of the series in 1987, several Japanese-originated sequel series were created.

In response to the 1993 relaunch of the toyline and its accompanying comic being called Transformers: Generation 2, this series and its comic book parallel are frequently referred to by the retronym, Transformers: Generation 1, aka G1. Initially a fan-coined term, it has since made its way into official use.
