The New Empire Gear was an organization heavily associated with machinery, robotics, and scientific experimentation.

Its leader, Doctor Man, was particularly notable for his scientific ambitions.

The villains therefore represented a dark mirror of Bioman’s own technological abilities.

This created a recurring Super Sentai idea: the heroes and villains can sometimes use similar technology for completely opposite purposes.

The conflict becomes not just good versus evil, but competing visions of how science should be used.
