What ArcHivist Hegelia termed the cranium bulge was the point at the very top of the Cyber-helmet, which was connected by side handles at either side to the faceplate headblocks across Cyber-subspecies. (AUDIO: The Cyber Nomads)

On the Cyber-body identified as CyberNomad, the area to the front of the cranium bulge contained a sophisticated energy weapon. Operated from the chest pack, it is capable of stunning or killing. (TV: Revenge of the Cybermen)
