- You may be looking for the Cyberman rank of Cyber-Leader.
Cyberon Cyberleader, or simply Cyberleader, was a rank in the Cyberon hierarchy.
On the eve of the Cyberon War, each of the Cyberon battle-cruisers which launched a surprise attack on Earth was under the command of a Cyberon Cyberleader, including Cyberon Cyberleader One and Cyberon Cyberleader Five. The two notably had unique appearances, with Cyberon Cyberleader One being painted black and Cyberon Cyberleader Five's helmet including a single, slit-like horizontal visor instead of the usual two circular eye-holes. All of them were subordinate to the Cyberon King, who remained behind on the Cyberon homeworld.
By the tail end of the War, on the other hand, a singular Cyberleader, again with a unique head-type, ascended to become the overall ruler of the Cyberon race, four years after the destruction of the Cyberon Controller who had himself succeeded the King. (COMIC: Before the Storm)
