Cyber-Leaders were a variant of Cyberman in the universe of Doctor Who. Within the Cyber-Empire's hierarchy, Cyber-Leaders were responsible for commanding entire legions of the Cyber-Army or even fleets of warships. In the event that neither a Cyber-Controller or Cyber-Planner were present, a Cyber-Leader could assume leadership of the entire Cyber race.
Cyber-Leaders would look mostly identical to other Cybermen, depending upon which generation. In most cases, the only visual aspect that set a Cyber-Leader apart from standard Cyber-Troopers was a set of black handlebars on the head. Fifth-generation Cyber-Leaders sometimes had black faceplates as well. They might also have transparent brain casings.
