Doctor Who: EVERY NuWho Villain And Monster Ranked Worst To Best
205. Spider Germs
Appear in: Kill the Moon.
Apologies to those with arachnophobia, but this is only the first spider or spider-like creatures we'll be seeing on this list.
The Doctor described them as "tiny, tiny bacteria", resembling massive spiders that came from an even more massive creature weighing around 1.3 billion tonnes which eventually hatched from within the moon.
The giant red and black germs launched themselves like facehuggers and could kill instantly, but as schoolgirl Courtney Woods demonstrated, you can take one out with some Dettol. Other antibacterial sprays are available.
