Savash chief science warlord
From Tardis Wiki, the free Doctor Who reference
In the early 2020s, the Savash chief science warlord was in a party of Savash who intended to overthrow and terraform the Earth. When St John Colchester explained to the Savash leader that Earth was worthless due to its rampant pollution, the chief science warlord scanned the planet and found seventeen waste dumps too large for their ship's terraformers to handle.
