Bidon

Bidon looms as a towering, blocky robot. A flat hexagonal head carries a pair of short horns that jut up like an ox's, split by a single narrow visor slit. Its smooth torso runs a tidy line of bolts straight down the middle, and broad slab-like plates armor the chest and shoulders, giving the whole machine the bearing of a walking fortress.

Bidon is a machine of pure obedience, built to carry out whatever orders The Organization hands down without deviation.

Bidon drops onto the scene together with the other three Machine God units, Meda, Salany, and Pushu, closing in on Suiryu just after he wrenches himself loose from the grip of his battle suit. No confrontation ever gets underway, because Saitama steps in and destroys all four of them in a single instant. Its disaster level is never stated outright, but as a Machine God robot it is presumed to hold formidable strength and durability, and it demonstrated the ability to fly at high speed during its plunge toward Suiryu's position. According to Sweet Mask, the entire Machine God line rates at least as Demon-level threats.
