Because everyone involved in the design, writing, and concept of the Cybusmen was a complete idiot.Well, you see, rather than being similar to humans, the original Mondasians were like the Silurians and had a third eye. Much like how they kept a face as they changed and developed over time, they also kept this third eye as a cultural thing. Then they did the sensible thing and stuck a gun in it.
Then why is there anything up there on the Cybusmen?
