The Brave series is a toy and anime franchise that began after toy company Takara had ended the animated "Generation One" storyline of Transformers in Japan. Following a decline in the series' popularity that led to the cancellation of the OVA series Transformers: Zone, Takara struck a cooperative deal with the animation studio Sunrise to develop a new franchise and set of toy lines. The franchise, in fact, would play a key role in the reintroduction of the Super Robot genre to the Japanese mainstream in the 1990s.
