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.
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.
- Big Bad: Averted, for there is once again no main villain organization to speak of. However, towards the end, Ryuichi Takaoka becomes a recurring character behind many schemes.
- Big Damn Heroes: KnightFire tends to do this.
- By The Powerof Grayskull: Plus Up!
- Cool Airship: Solid State-1
- 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.
- 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.
- Cop Show
- Darker and Edgier: Compared to its predecessor, there is a bigger amount of serious episodes and less comedy.
- Law of Inverse Recoil: Averted when the Gigastreamer makes a quick comeback — where it isn't fired so much as pointed in the same general direction as the target with brute strength and a prayer — but luckily R&D came up with a safer replacement, the Pile Tornado (which is given to both SolBraver and KnightFire).
- Licensed Game: Notable for being a reskinning of the original game Shatterhand.
- The Medic: SolJeanne
- Overarching Villain: After episode 35, Ryuichi Takaoka serves as this for several of the succeeding episodes.
- Plucky Comic Relief: Kamekichi and (to a lesser extent) SolDozer, when the situation calls for it.
- Stock Footage: Like last time, with the new addition of the SS-1 being launched to fight fires.
- Transforming Mecha: SolDozer
- Wham Episode: Episode 34.
- Younger Than They Look: SolDozer, since he gets brought to life in the first few episodes and thus has the mindset of a child.
