Description
Dumpson, designated BP-303 and also known as the Wrestler Detective, is a member of the Build Team within the Brave Police unit. His teammates include BP-301 McCrane, BP-302 Power Joe, and BP-304 Drill Boy. His alternate vehicle mode is a dump truck.

He possesses a straightforward, formal, and stubborn personality. Dumpson takes his duties seriously, rarely jokes, and is prone to arguments with others, including the team's young leader, Yuuta Tomonaga. He is armed with a standard-issue revolver, a mechanical Brave Police notebook, and a pair of spiked dumbbells.

Dumpson shares a significant friendship with freelance reporter and photographer Ayako Kimizuka. They first met under rocky circumstances but grew close due to their shared headstrong natures. During that initial encounter, they worked together to rescue other Brave Police members from a criminal robot and saved Yuuta from imminent danger. Their partnership was demonstrated again during an investigation into an illegal robot wrestling ring and the disappearance of famous wrestlers, where Dumpson went undercover as a robot wrestler with Yuuta as his controller.

In team operations, Dumpson can combine with McCrane and Power Joe to form Build Tiger. This combination can be further enhanced by uniting with Drill Boy to form Super Build Tiger.

Beyond the television series, the character appears in the video games *Brave Saga* and *Brave Saga 2*. In the latter, a narrative event involves Dumpson and Drill Boy being captured by a character named Doza. They were subsequently rescued by Ayako Kimizuka before regrouping with the other Build Team members to form Super Build Tiger.
