Emperor Type II

The Dalek Emperor in the Last Great Time War was housed in a huge, static casing which exposed the mutant in a clear tank. Time Lord historians at the time of the Last Great Time War designated it as the "Emperor Type II", (PROSE: Dalek Combat Training Manual)

After this Dalek Emperor was finally killed by Rose Tyler when she became the Bad Wolf, (TV: The Parting of the Ways) a blue casing of the same type was used by the Emperor Dalek installed by the New Dalek Paradigm in an ultimately-aborted timeline. (GAME: City of the Daleks)
