Description
Deckerd, designated BP-110, is the inaugural Brave Police robot created by the Tokyo Metropolitan Police Department. Equipped with experimental Super-AI for advanced crime-fighting, his physical design incorporates transformation into a Chevrolet Corvette C4-based police cruiser. Integrated equipment includes a standard-issue revolver stored in his right skirt armor and a mechanical police notebook displayed on his chest signifying his authority.

Initially programmed non-sentient, Deckerd's exposure to 10-year-old Yuuta Tomonaga during development unexpectedly catalyzed his Super-AI evolution. Yuuta's persistent interactions and emotional bonding caused Deckerd to develop self-awareness, human-like emotions, and a distinct personality. This fundamentally altered his operational parameters and enhanced his combat abilities beyond design specifications. His emotional core became the foundational template for all subsequent Brave Police robots, as their AIs derived from his. Deckerd's personality is characterized by honesty, empathy, and a strong sense of duty, often mediating team conflicts and leading with a focus on cooperation. However, he exhibits vulnerability to isolation, occasionally leading to irrational behavior or emotional distress when separated from companions.

A critical early event involved a mandated memory reformatting to erase his bond with Yuuta upon joining the police force. During transport, an attack by the criminal Dr. Gauss threatened his capture. Yuuta's intervention during this crisis reactivated Deckerd's suppressed memories, enabling him to defeat Gauss and solidify his partnership with Yuuta, leading to Deckerd residing long-term with the Tomonaga family.

In combat, Deckerd serves as the core component for multiple combined forms. Combining with the SWAT van J-Roader (based on a Kenworth L700) forms the humanoid super robot J-Decker. This form employs the J-Buster rifle, stored in the right leg with selectable ballistic or beam firing modes, and an Electromagnetic Baton stored in the left skirt armor capable of delivering electric shocks. J-Decker, typically deployed against large-scale threats, can integrate with ally GunMax and his Gun Bike to form the powerful shoulder-mounted weapon, the Max Cannon. A further combination with Duke Fire (composed of Duke and the Fire Roader) creates Fire J-Decker. This form wields enhanced weaponry including the Fire Arm claw, Fire Drill, and the Fire Sword broadsword stored in the left skirt armor. Its finishing move, the Burning Fire Sword, engulfs the blade in flames for a decisive slash. The Fire Sword: Rolling Thunder variant electrifies the sword for ranged or melee attacks. Fire J-Decker retains access to the Max Cannon.

Deckerd's operational history includes significant trauma. During a confrontation with the Chieftain robots, he was severely damaged and forcibly merged with the malevolent entity Gaizonite, becoming the brainwashed "Satan J-Decker" used to attack allies. After Gaizonite's defeat, Deckerd regained autonomy but suffered total memory loss due to physical and psychological trauma. He initially resisted memory recovery attempts, distraught at potentially endangering Yuuta, and agreed to a reprogramming. His memories were later fully restored through unknown means.

In spin-off media like *Brave Saga* and *Brave Wars*, Deckerd/J-Decker functions as a versatile unit, often unaffected by terrain penalties and utilizing the Max Cannon for specific combat scenarios. These narratives sometimes depict alternate timelines, such as his temporary replacement by other robots before returning to active duty.
