Draal (species)
From Tardis Wiki, the free Doctor Who reference
The Draal were a species of bipedal arthropod from an oceanic Earth colony. Though covered with a thick carapace, they could be disabled or killed by karate chops, which transmitted the force to the tissue underneath. A Draal refugee from Dellah was imprisoned in the detention complex of Thanaxos. (BNA: The Mary-Sue Extrusion)
