Transformers: Generation 1 is a toy line from 1984 to 1990, produced by Hasbro and Takara Tomy. It was a line of toy robots that could change into an alternate form by moving parts into other places, and it was the first line of toys produced for the successful Transformers toy and entertainment franchise. The line was originally called The Transformers, with "Generation 1" originating as a term coined by fans of the toys when the Transformers: Generation 2 toy line was released in 1992. Hasbro eventually adopted the term "Generation 1" to refer to any toy produced in that era.

An action figure is a poseable character model figure made most commonly of plastic, and often based upon characters from a film, comic book, military, video game or television program; fictional or historical. These figures are usually marketed toward boys and adult collectors. The term was coined by Hasbro in 1964 to market G.I. Joe to boys.
