Cyber-Lieutenant (The Five Doctors)
From Tardis Wiki, the free Doctor Who reference
A Cyber-Lieutenant, along with a Cyber-Leader and a squad of Cybermen, was Time Scooped by Borusa to the Death Zone.
It fired at the Fifth Doctor and the Tremas Master. The Doctor escaped with the Master's homing beacon, while the Master tricked the Cybermen into working with him. The Master led a group of the Cybermen to the Dark Tower. These Cybermen attempted to cross a chessboard-patterned floor and were all electrocuted. Meanwhile, the Lieutenant and other Cybermen placed explosives around the Doctor's TARDIS. The TARDIS safely dematerialised before the explosives could be detonated. (TV: The Five Doctors)
