Grecks

Grecks was a marshal of the Sontaran Sixth Column, a squad of Sontarans brought to the Death Zone by Borusa. There, they encountered the Fifth Doctor, his companions and the Daleks. After finding out that there was a gateway that the Daleks had and could be used to escape the Death Zone, Grecks ordered an attack against the Daleks to take the gateway. Upon realising that there wasn't enough power from either the Sontarans or the Daleks to power the gateway, Grecks decided on an alliance between them both. However, he and his squadron were all killed by the Daleks. (AUDIO: The Five Companions)
