Cotton (The Mutants)
From Tardis Wiki, the free Doctor Who reference
Cotton, along with Stubbs, was an aide to the Marshal of Solos. Unlike him, they wanted Solos to be granted independence from the Earth Empire. When the Doctor, Jo Grant and Ky fled to the caves on Solos, the Marshal sent Stubbs and Cotton after them, but then sealed them in also. They then agreed to help the Doctor help the Solonians.
