Broken Tooth

Broken Tooth was one of the inhabitants of the UK Habitat who was saved from the cullings by Merdeen and sent to live on the surface. There he joined the Tribe of the Free and became Queen Katryca's right hand man. He led the party that found Glitz and Dibber and escorted them to Katryca, disarming Glitz when he pulled a gun on her.

After witnessing the escape of Glitz, Dibber and Peri, Broken Tooth led the hunting party that tracked them to the station. Recognising Balazar when they met up with him and the Doctor, he shot the L1 robot in order to save them, then took the group prisoner. Both he and Balazar refused to speak for the Doctor and the others with Katryca, fearful of retribution. After seeing the L1 robot (which they believed to be the Immortal) abduct the Doctor, he helped Katryca destroy it.

When Katryca decided to raid the underground to plunder the Immortal's secrets, Broken Tooth and Balazar agreed to act as their guides. They gained access to the Immortal's castle while Humker and Tandrell were escaping, but were confronted by Drathro. When Drathro began to electrocute Katryca with his grip, Broken Tooth attempted to intervene and was also electrocuted. (DW: The Mysterious Planet)
