Doctor Who: EVERY NuWho Villain And Monster Ranked Worst To Best
209. Chip
Appears in: New Earth.
When the chips are down (so sorry) like they were for Lady Cassandra after her failed Platform One plan went splat in The End of the World, go grow yourself a slavish clone based on your favourite pattern. It's only natural, therefore, that the unnatural Chip is a villain by association.
He helped his mistress trap Rose in a psychograft which allowed Cassandra's mind to take possession of Rose's body. Eventually, Chip willingly allowed her to use his half-life body like the good walking doodle he is.
