Cyber-Leader (Made of Steel)

A Cyberman that was part of surviving Cybermen made from humans converted during the Battle of Canary Wharf (meaning they had not crossed the Void so they were not contaminated with Void stuff, thus not being sucked back in) became a Cyber-Leader after the battle. The Cybermen planned to open the Void and free the Cybermen trapped inside, but their plans were thwarted by the Tenth Doctor and Martha Jones. The Cyber-Leader was electrocuted by their own force field. (PROSE: Made of Steel)
