Tenma quickly realizes that while the robot possesses Toby's memories, it is not exactly like his original son, as the robot's higher mental and physical powers frequently remind him. Tenma had initially included the robot's powers in order to prevent his "son" from being destroyed again. Unaware that he is a robot, Toby tries to figure out why he can understand the language of some robot cleaners and discovers he can fly via rocket-boosters hidden in his shoes. He discovers various other abilities and heads home to tell his father, only to find that Tenma and Elefun are discussing deactivating him. Tenma reveals to Toby that he is a robot. President Stone's men detect the Blue Core's energy signature and pursue Toby. Stone calls in the Spirit of Freedom: a massive, heavily armed, flying battleship. Rendered unconscious, Toby falls off the floating city and lands in the junkyard below. He meets several children including Cora, a girl who left Metro City after her parents neglected her, and a robotic dog named Trashcan. Toby meets the Robot Revolution Front: Sparx, Robotsky and Mike the Fridge, who easily identify Toby as a robot and rename him "Astro". Astro goes along with his new name and lives with the children and their fatherly figure, Hamegg, who appears to care for broken robots, but secretly treats robots just as callously as Stone, and also runs the Robot Games: destructive gladiatorial matches in which robots are forced to fight to the death.
