Formerly the Grand Wizard of the Knights Martial, Deadlock and his brothers were given special authority to try and execute Volgan war criminals during the conflict. Rumours of secret ceremonies and strange experiments surrounded them, but unknown to anyone outside of the walls of their watchtower, they also studied the dark path to something they called Khaos. Deadlock’s status (and powers) made him a must for the Mars mission, so Hammerstein was dispatched to bring him in. After losing a duel, Hammerstein tricked the wizard into relinquishing his weapon, the Ace of Swords, and forced him into coming to the devil planet. After the mission was complete, Deadlock returned to Earth to take command of his Knights Martial once more, but discovered much had changed in his absence. The watchtower used by the Knights to scan the planet from space had landed, and the Knights themselves were indulging in frivolous pursuits – ignoring the old values of meditation, purity and discipline which Deadlock cherished. In time they would be replaced by a new human order, The Terminators, who would twist those values into a doctrine of hatred for all alien life-forms.
