History
These humanoid robots were built by Victor von Doom and kept at Castle Doom. When Doom intended to use the Particle Projector to erradicate nuclear weaponry, he was opposed by teenage superheroes Cloak and Dagger, who escaped Doom's direct attack. Doom sent his roboid drones to look after the heroes within the castle, but the drones failed to find them - albeit the heroes were in the first place anyone should have looked, the Particle Projector chamber.
