Adherents of the Repeated Meme
The Adherents of the Repeated Meme were a group of robots used by Cassandra O'Brien.
They look like large black cloaks with gold necklaces and appear to have only one metallic arm. These androids were used to carry the Metal spiders and to allay suspicion away from Cassandra at the end of the world party, where they supposedly represented Financial Family Seven.
Cassandra also had them trap Rose Tyler in a room with its sun filter descending as revenge for insulting her earlier. The Adherents were discovered and shut down by the Doctor when he ripped off one of their arms. (DW: The End of the World)
They could be a reference to the bad wolf meme.
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.
