Adherents of the Repeated Meme

The Adherents of the Repeated Meme were a quintet of robots used by Cassandra O'Brien.

Appearance
The Adherents of the Repeated Meme were cloaked in black and their heads were concealed behind black masks, making sure their true identities remained hidden. The Adherents of the Repeated Meme had grave-like voice, almost like very loud whispers. The Adherents of the Repeated Meme had metallic hands and wore yellow chains around their necks which indicated rank. They weren't entirely robotic, being composed of organic ganglia strands connected to their hand. The Adherents of the Repeated Meme were operated remotely by Lady Cassandra herself. (TV: The End of the World)

History
These androids were used to carry and offer the stainless-steel orbs as a "gift in good faith" to the guests but these orbs secretly housed the metal spiders. One of their other main purposes was to allay suspicion away from Cassandra at the end of the world party, where they supposedly represented Financial Family Seven.

Cassandra also had them knock Rose Tyler unconscious and drag her in a room with its sun filter descending as revenge for insulting her earlier. The Adherents of the Repeated Meme were discovered and their cloaks collapsed to the floor when the Ninth Doctor used his programming knowledge to make a metal spider go back to their master. One of the Adherents of the Repeated Meme attempted to strike the Doctor and he ripped off its right hand. He then snapped the gangila strands and the quintet shut down, and their now hollow-looking cloaks suddenly dropped-to the floor. (TV: The End of the World)

Behind the scenes

 * The Adherents' only appearance is in The End of the World, the first episode in which the repeated Bad Wolf meme is adhered to. Their name is most likely a reference to that plot device.
