Charles Brenten commands the Tank Police unit as its brash squad leader, wielding a macho swagger and notorious indifference toward protocol or civilian welfare. His signature weapon, the massive vintage revolver dubbed “the Castigator,” cements his status as the unit’s premier sharpshooter. A lifelong *How to Kill* Magazine subscriber, his expertise centers on combat techniques and armaments.

Debuting in the original manga and OVA series, he persists as a pivotal figure in spin-offs such as *New Dominion Tank Police* and *TANK S.W.A.T. 01*, where his authoritarian leadership sparks friction with subordinates and superiors alike. Aggressive maneuvers define his strategy, escalating tensions with officials wary of excessive collateral damage.

Physically imposing, he towers over six feet with a broad-shouldered frame, jet-black hair, and a thick mustache. His rugged image, likened to a “Tom Selleck on steroids,” is anchored by perpetual sunglasses and a cigar. Personal ties include marriage to Sumaiza and kinship with Brady, his 300-pound wrestler brother. His surname pays homage to the Bren Ten 10mm handgun, famed from *Miami Vice*, though early translations sometimes erroneously rendered it as “Britain.”

In *Crusher Police Dominion*, he partners with gunner Charlie Nam, deploying heavy artillery and irregular tactics during operations. Later continuities such as *Dominion Conflict One: No More Noise* recalibrate the Tank Police structure but preserve Brenten’s unwavering focus on overwhelming firepower. Frequent clashes with Leona Ozaki over her experimental tank modifications and rogue methods underscore his rigid commitment to militarized policing.

Official narratives maintain his static portrayal as an authoritarian enforcer, prioritizing tactical dominance over personal evolution or expanded backstory.
