Defence Advocate 997
From Tardis Wiki, the free Doctor Who reference
Defence Advocate 997 was the defender for the Dastrons during their trial. However, the spacecraft they were on crashed in Dunstanton Lake and centuries later, the Defence Advocate was re-activated by Freda Mattingly. It later took control of the Ex-Cav suit and had it steak the key to awaken the Dastrons from their suspended animation. (AUDIO: Prisoners of the Lake)
