Dynatrope
From Tardis Wiki, the free Doctor Who reference
A Dynotrope was a spaceship used by the race known as the Krotons and was powered by mental power.
One crash landed on the Gond's planet, with its crew in stasis in their liquid slurry form. (DW: The Krotons)
Another Dynotrope was encountered on Onyakis. (BFA: Return of the Krotons)
Like the Krotons themselves, the ship was also vulnerable to sulphuric acid.
