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. (DW: The Krotons)
One crash landed on the Gond's planet, with its crew in stasis in their liquid slurry form.
Another Dynotrope was encountered on Onyakis. (BFA: Return of the Krotons)
Like the krotons themselves, the ship was also vulnerable to sulphuric acid.
