Xenomorph

A creature whose larvae attatch to your face and inject themselves in your digestive tract, where they mature into adults and burrow out of you, killing you in the process.

Nobody would want to have a Xenomorph on their planet, given the way they wiped out the colonists and the Marines in the first Aliens movie.
