Tokkyuu Shirei Solbrain is the ninth entry in the Metal Heroes franchise, airing from 1991-1992. It is the second of its Rescue Heroes trilogy.
After the Winspector team leaves Japan to fight crime in France following the finale, Masaki Shunsuke creates a new team, named Solbrain, to continue Winspector's duty to take out crime and disaster when it strikes the city. The new heroes Daiki, Reiko and SolDozer must always be on hand to stop all disasters.
The main heroes are:
- Daiki Nishio/SolBraver: The Hero.
- Reiko Higuchi/SolJeanne: The Chick.
- SolDozer: The lone Ridiculously Human Robot on the team; The Big Guy.
- Ryoma Kagawa/KnightFire: Formerly The Hero of Winspector, joins the team mid-series as The Lancer.
Recurring Metal Hero tropes include:
- Big Bad: Towards the end, Ryuichi Takaoka becomes a recurring character behind many schemes.
- Cool Car: Daiki's Toyota Sera and Ryoma's Mazda RX-7. Don't forget Reiko's Toyota Previa minivan. All are customized for the show purposes.
Tokkyuu Shirei Solbrain provides examples of the following tropes:
- 20 Minutes into the Future: Downplayed compared to the previous show which frequently assured viewers it was 1999, but it can be assumed that is circa 2000.
- Close-Knit Community: Episode 14 features one of these, dealing with the ramifications of their local precinct's model cop refusing to shoot a youth he was acquainted with.
- Darker and Edgier: Compared to its predecessor, there is a bigger amount of serious episodes and less comedy.
- Licensed Game: Notable for being a reskinning of the original game Shatterhand.
