Slitheen Delta

A member of the Slitheen family disguised himself as Delta Bluestone, using Delta's skin as a skin suit, alongside his partner who was disguised as Delta's brother Dench. Appropriating the Bluestones' culinary business on resort planet MXQ1, the Slitheen earnt money by selling livers taken from the sentient lifeforms who dined and worked at the resort. Among their unwitting customers were their cousins, the Hazrateen, who the Tenth Doctor knew as a peaceful and law-abiding family. The Hazrateen were made aware of the Slitheen's activities when Rose Tyler made contact from MXQ1, and they promptly sent a ship from Raxacoricofallapatorius to apprehend two Slitheen. The Hazrateen leader assured the Doctor that they would be incarcerated rather than executed. (AUDIO: The Taste of Death)
