"Unnamed BX-4" was a planet the sentient superweapon the Hadax Ura was found at after it escaped from the Hub Alliance. Its wildlife, cybernetically modified by the Hadax Ura, included anthropoids with limited intelligence which were used by the Hadax Ura as scouts, as well as pterosaurs and dinosaurs. An intelligent civilisation existed on the planet, and lived in the memory of a computer known as the Jungle, their "final creation", which was indistinguishable from a natural jungle. One moon orbited the planet. A team including Mr Hitch, the Twelfth Doctor, Clara Oswald, Mr Wiremu and Gela landed on this planet to recover the Hadax Ura. All of the team apart from the Doctor and Clara were killed, and the controlling intelligence of the Hadax Ura burnt up in the atmosphere. (COMIC: Spirits of the Jungle)
