Boy/Harry Boy: Jiban's robotic assistant. He stays at his secret base. Originally he was simply Boy, an immobile camera-like robot who had to give instructions to Mayumi to operate the control center, but then his computer was transferred to panda-like "Harry" (a robot devised by another student of Doctor Igarashi's) and began substituting for the amnesiac Mayumi. He died when Jiban's base was destroyed. In the Filipino Dub, it was renamed as Tikboy.
