When the Daleks fired their anti-missile rockets towards the warhead stolen by 2K, the launch disturbed a nearby Terrorkon. (COMIC: Impasse) One Terrorkon broke through an electric barrier and attacked the Daleks working in the Lake. It then stole a missile and headed through an underground river into a cave deep in the mountains. Finding the missile inedible, it threw it away, which activated it. The Dalek Emperor and the Red Dalek followed the Terrorkon, defused the missile, and observed as the creature was attacked and killed by an giant eel. (COMIC: The Terrorkon Harvest)
