: Unveiled in Episode 41 by Regina, the British Brave Police are 4 transforming robots with Super A.I. units installed.

It was likely that Takara did plan to release these characters as toys, but changed their plans and the toys were never produced and the British Brave Police only appeared in the series in their robot modes as a result. They would later re-appear briefly in episode 46, where Duke revealed at least two of their names to be Rook (ルーク Rūku) and Bishop (ビショップ Bishoppu) (Their names likely inspired by chess pieces) before the four of them get destroyed by being under the control of the Hamlen waves.
