Thomas (The Pit)

From Tardis Wiki, the free Doctor Who reference

Thomas was a Killer-type android used by the Justice Police in the Althosian system.

He was part of a team sent to the seventh planet to retrieve Pandora's Box. The rest of the team was killed by Butler after they landed, but Thomas accidentally killed Butler when he knocked him into a patch of time-stopping red weed.

He was captured later with Ell Romer and Bernice Summerfield by Butler's partner Swarf. Thomas tried to kill Swarf, but was killed instead. (PROSE: The Pit)
