During the Total Collapse Event Incident, (PROSE: Dalek Combat Training Manual) a Cyber-Leader led the Cybermen who joined the Pandorica Alliance formed to imprison the Eleventh Doctor in the Pandorica in order to save N-Space. It appeared, flanked by two other Cybermen, via teleport to Stonehenge, 102 A.D., along with the other Alliance representatives as they locked the Doctor in the Pandorica. (TV: The Pandorica Opens) After the Alliance's plan failed, several species - including the Cybermen themselves - were erased from existence, leaving only stone "after-images" behind. The Doctor ultimately rebooted the universe, restoring them all to their proper places in space and time. (TV: The Big Bang)
