Sontarans are a clone species that always manage to look markedly different in every story. Central to their character is the fact that they are manlets, so they're always trying to fight everyone.
- Sontarans reproduce by cloning (aka. inbreeding) and are nearly identical to each other (apparently).
- Their main weakness is a glory hole on the back of their neck which if penetrated can stun or kill them.
- Sontarans have an insatiable appetite for human female thorax.
The Doctor Edit
The Doctor has fought the Sontarans a bunch of times and has now enslaved one for comic relief.
