Metebelis IV

Metebelis IV, or Metelbelis Four, (PROSE: ) was a planet that drifted out of its orbit into the outermost ring of the Acteon Galaxy. It was a barren, untouched paradise with cerise coloured sands and emerald skies. (AUDIO: The Vanity Trap) Voice eating wombats were lived on the planet. (PROSE: )

The Thirteenth Doctor considered it to be "better than Metebelis III but nowhere near as good as Metebelis I or II". The sands of the planet were infused with a substance which could block a Zeiton tracker. Metebelis IV was also stated to be "somehow alive, as if its natural elements [were] sentient...". (GAME: The Edge of Time)

History
The Sixth Doctor intended to go there with his companion Peri Brown, but instead landed on Earth. (AUDIO: The Vanity Trap)

In the late 20th century, at least relative to Sooty's native time period on Earth, he and Iris Wildthyme had encountered voice eating wombats and their green crystals on Metebelis Four. The wombats took Sooty's voice and stored it in their Cacophany of Doom. The next time Iris and Sooty met, while Sooty and the rest of the cast of The Sooty Show were waiting for the bus to the seaside, Iris realised Sooty was still missing his voice and told him she'd "sort it out". (PROSE: )

Behind the scenes

 * Prior to the release of The Vanity Trap Metebelis IV appeared in the virtual reality video game The Edge of Time. In the game, Metebelis IV was a sentient planet that was the site of the Temple of the First and was invaded by Bronze Daleks seeking to harness the power of zeiton crystals. The Thirteenth Doctor and a companion controlled by the player both go to the Temple.
