Adherents of the Repeated Meme
From Tardis Wiki, the free Doctor Who reference
The Adherents of the Repeated Meme are a group of robots used by Lady Cassandra. They look like large black cloaks with gold necklaces and a single metallic arm. These androids were used to carry the Metal Spiders and to allay suspicion away from Lady Cassandra. (DW: The End of the World)
