Despite the preparations made by the Legion and Science Police forces, Robotica has successfully invaded Earth in a matter of minutes! To take the planet back, the Legionnaires head for a nearby world with centuries-dormant - but still lethal - warlike capabilities. But what - or whom - they find there is not to be believed! Then again, neither is the leader of Robotica, who finally meets Brainiac 5 face-to-face!
As the Robotica begins it´s assault on Earth, The Legio struggles to breach in it´s forcefield, what proves to be a difficult task, so they search for a big weapon (Pluto, the Warworld), while the Coluan people try to figure out how to go through the field; in Earth Brainiac is captured and Mr. Venge reveals himself to be Computo.
