Cyber-Leader (Alit in Underland)
From Tardis Wiki, the free Doctor Who reference
A Cyber-Leader came up from Floor 1056 to Floor 0507 after discovering life signs originating from there, which turned out to be Missy, the Saxon Master and Alit. It attempted to take the Master back down to Floor 1056 for cyber-conversion, but it and its group of Cybermen were destroyed by Missy. (PROSE: Alit in Underland)
