Death Wheel

The Death Wheel was the Dalek ship that was in the orbit of the planet Hell. The Seventh Doctor and Abslom Daak infiltrated the ship after they found out the Daleks mined helkogen to build a genocide machine so that the Daleks would gas entire planets. Abslom sacrificed his life to destroy the Death Wheel and Daleks' plans. (COMIC: Nemesis of the Daleks)
