boss borot
A fictional mecha from the Mazinger Z super robot TV anime from the 70s.
Boss Borot is a giant robot that primarily serves as the comic relief for the series. It was made out of junk by Doctor Morimori, Doctor Sewashi and Doctor Nossori. It is piloted by Boss, Mucha and Nuke.
While it does not have any weapons -since their use would destroy or melt the mecha's main superstructure-, the robot is very strong and has mechanical strength that equals (or even surpasses sometimes) that of Mazinger Z.
The robot uses common car fuel as main power source and is controlled with a simple steering wheel. This inspired the controls of the Megas XLR from the American show of the same name years later.
