Duke Fire is a super robot from the Brave Police J-Decker series.


Duke Fire is the combined form of Duke and Fire Roader. Duke Fire's main weapon is a large sword, and can combine with J-Decker to form Fire J-Decker.

Duke Fire and his components were designed by Regina Argine, and built in England, but later joined the Japanese Unit of the Brave Police. He often will tag-team opponents with J-Decker, and will form Fire J-Decker if the opponent is too large or powerful for both of them to handle.
