One of Bojack's henchmen. His name is derived from the Japanese word hidou, which means "unjust", and is often pronounced bidou when added to the end of words like gokuaku and zangyaku (similar to the names of Bidou's comrades Kogu [specifically his Japanese name Gokua] and Zangya respectively).

He often collaborates with Bujin in battle, taking down the foes that Bujin traps within his needles of energy.
