AstroBoy

AstroBoy is the main character in the AstroBoy series. He was created after the human Astro was based on (Tobio/Toby) was hit by a car and killed. His dad, filled with grief, made a robot version of him. He named him Astro Boy, after his son.

Role in the Movie
The film is set in the futuristic Metro City, a metropolis which floats in the sky above the polluted "Surface". Metro City's population is aided by a multitude of different robots who are dumped on the Surface when broken or disused. Toby, son of Dr. Tenma, learns that his father is going to show President Stone, the militaristic leader of the city, the Peacekeeper, a new guardian robot that he's been working on. Doctor Elefun, one of Tenma's colleagues, introduces Stone to the Blue and Red Cores, two energy spheres mined from a star fragment, that produce energy which can power robots via positive and negative energy, respectively. Stone places the Red Core in the Peacekeeper, causing it to go out of control. The Peacekeeper tries to attack the humans, but Tenma puts a barrier between them. Meanwhile, Toby has been released early from school, and rewires Orrin, his family's robot, in order to attend the Ministry of Science's demonstration of the Peacekeeper. Seeking to have a closer look at the Peacekeeper, Toby enters the same room as the robot, only for the Peacekeeper's first attempt to destroy the barrier to backfire with the result that Toby is totally annihilated. After the Peacekeeper is stopped by security forces, Dr. Tenma, wracked with despair, builds an identical robotic clone of Toby, using DNA from a strand of his hair to obtain his memories, which will make the robot think he is Toby. He also powers the robot with the positive blue core. The robot quickly comes to life, and Tenma brings him home.

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.

Astro and his friends find an offline construction robot named ZOG, and Astro secretly revives ZOG. The kids bring him back and clean him up for the Hamegg games. Later that night, Astro comes across Cora trying to call Metrocity. She reveals to him that she actually has parents and was worried if they even missed her. Astro promises not to tell and tries to tell her his secret but can't. The next day at the Hamegg games, Hamegg betrays Astro, learning of him being a robot, and pits Astro against other robots in the Robot Games. Unable to simply leave, Astro reluctantly destroys all the robots. Hamegg releases ZOG for Astro to fight, but both refuse to fight one another. Stone and his men arrive then and arrest Astro. They take him back to the Ministry of Science, where Tenma is asked to remove the Blue Core; however, at the last moment, he has a change of heart, accepting that even if Astro isn't Toby, he's still his son, and allows Astro to escape. Stone places the Red Core into the Peacekeeper again, only for it to absorb him and take on his consciousness. Astro and Stone fight across the city, demolishing most of the buildings and causing the city to begin crashing to Earth. Astro is able to slow Metro City's decent by flying underneath and pushing upwards with his leg-rockets. Cora, the other children, and the Robot Revolution try to help to bring down the Peacekeeper/Stone fusion. Stone catches Astro and is about to absorb him, but when the Blue and Red Cores clash, he lets Astro out due to the close proximity of the two Cores causing him great pain.

Astro lands in a building, where he reunites with Tenma. Tenma tells him that if the Blue Core and Red Core come together, Astro and the Peacekeeper will both die. Astro decides that this was the reason he was made, and flies straight toward Stone, crashing into him and merging the Cores which destroys the Peacekeeper and frees Stone (who is knocked out from the collision). However, with both Cores drained of energy, Astro is deactivated. Cora, Dr. Elefun and others find Astro's body. ZOG transfers some of his Blue Core energy (which Astro kindly gave him) to Astro; with the catalyst restarted, the Blue Core once more becomes a limitless source of energy, so Astro is easily revived and his wounds automatically heal. Astro is reunited with Dr. Tenma, and Cora finds and makes up with her parents. Stone awakes, only to be arrested by his own troops. When an alien life-form appears over the city, the movie ends with Astro flying up to battle it.
