Synopsis:
In the far-flung future, mankind has produced intelligent machines to do their dirty work. These so-called ABC Warriors (due to their immunity to Atomic, Biological and Chemical warfare) fought and died for their masters, treated like slaves. When the Soviet Union was overtaken by a group called the Volgans, the world was plunged into war again. Deadlock was created to lead the Knights Martial, a group of specially designed robots meant to monitor the Earth from space and were given special authority to judge war criminals. Their isolation in space allowed them to discover dark secrets of the universe, becoming agents of Khaos, the all-powerful force of change. Deadlock, in particular, became a powerful mystic and was eventually recruited by the original ABC Warrior, Hammerstein, for a final mission- being sent to the new frontier, Mars, to clean up the planet.
After a member's tragic death, the ABC Warriors split up for several centuries before reforming and breaking up several times to... Increase the Peace! Spread the Word!
