Doctor Who: EVERY NuWho Villain And Monster Ranked Worst To Best
216. Handbots
Appear in: The Girl Who Waited.
These robots aren't bad - it's just that they could potentially kill you with "kindness" by firing hypodermic darts at you from their heads if you're deemed to be carrying unregistered bacteria.
