Wrarth Warrior

The Wrarth Warriors were a police force created by the Star Council specifically to deal with the Meeps.

Biology
The Wrarth Warriors were arthropods, with a tough exoskeleton. With their external skeleton acting as a skelo-shield they had formidable strength. Their eyes were like large lights and gave them excellent infra-red night vision (susceptible to ultra-white light). Their teeth were razor-sharp and their tongue were developed with digits to secure their food. They had a giant detachable claw on the left arm and a five digit tendrilled hand on the right.

History
During the war with the Meeps, the Wrarth Warriors were created by the Star Council to combat them. Following the Battle of Yarras, the Meeps were defeated, but their leader, Beep escaped. Circa 1980, Constable Zreeg and Sergeant Zogroth were sent in to try to find him. They both arrived on Earth and with the Doctor’s help Beep was taken into custody. (DWM: The Star Beast)

When the Slitheen family started their criminal activities, the Wrarth Warriors stopped them. (REF: Doctor Who: Monsters and Villains)
