The Transformers (retroactively called Generation One or G1) started as a joint venture between two companies: Hasbro of America and Takara of Japan. After an idea to rebrand and sell Takara's Diaclone and Microchange robot toys as a whole new line with a new concept behind it, Hasbro unknowingly would wind up creating what would be one of its longest running franchises.
