A Cyber-Planner sent a group of Cybermen, led by a Cyber-Leader, from Floor 1056 to Floor 0508 of a Mondasian colony ship on a mission to prepare the ship’s Cybermats for an attack on Floor 0507, and to capture the Master and Missy so they could be interrogated by the Cyber-Planner as to how the Cybermen's definition of humanity had been altered. However, these Cybermen were killed by the Master when he fired his laser screwdriver at the steel ground of Floor 0508 after Missy hacked the floor’s weather system to force it to rain, causing the resulting electrical surge to destroy the Cybermen.
