Mitran
From Tardis Wiki, the free Doctor Who reference
The Mitrans were the natives of Mitra B.
Rascla was going to infiltrate the peace talks on Mitra B and release germs that would turn the Mitrans homicidal. In the ensuing chaos, he and his Tormian Toad-men could take over the planet and its entire star system. His plans were stopped by the Fourth Doctor. (COMIC: The Body Snatcher)
