Scrofolus

From Tardis Wiki, the free Doctor Who reference

Dr Scrofolus was employed on the Dollar Intergalactic project of terraforming Isen VI in the 25th century.

He was an aquatic creature and required an air-space suit filled with liquid. The suit was supplied with a mechanism allowing to spray this liquid, which Dr Scrofolus used to read markings on the alien ship.

When the pod of his Team 12 was caught in a sudden earthquake, the Twelfth Doctor saved the team by landing the TARDIS inside the pod.

Later Scrofolus helped the Doctor and Clara Oswald to defeat Rann-Korr. (COMIC: Terrorformer)
