Transformers: Generation 1

Transformers: Generation 1 is a toy line from 1984 to 1990, produced by Hasbro and Takara Tomy. Inaugurating the successful Transformers toy and entertainment franchise, the line of toy robots could change into an alternate form by moving parts into other places. 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.
