Pluto (Astro Boy) - Manga

Manga

Urasawa's Pluto is significantly darker as he is seemingly capable of murdering humans and robots, and is extremely powerful, possessing some control over the weather by generating fierce tornadoes. He goes on to kill the entire "Bora Investigation Squad", always leaving behind a corpse with horn-like protrusions next to it.

Despite this, "Pluto" is actually Sahad, a peaceful, quaint, robot with a strong affinity towards nature and who wished to fill his desolated country of Persia full of flowers. He was created by the Persian Minister of Science, Dr. Abullah. Devastated by the 39th Middle-East War, with his country left in shambles and his family dead, Abullah came to harbor an intense hatred and vowed revenge. He died during the war as a result of a bombing, but before dying, he left the genius Japanese scientist, Dr. Tenma (creator of Atom, the story's version of Astro Boy), with a chip containing part of his brain, and full of Abullah's hatred towards the world. Tenma used the chip to awaken the perfect AI he and Abullah had been working on (due to being programmed with 6 billion personalities, the robot would take an infinite amount of time to simulate all the possibilities and would never awaken; Tenma had theorized that this could be overcome by programming intense, polarizing emotions into it, such as hatred, rage, and despair). The robot awoke, and despite believing itself to be Abullah, it also created a second personality, "Goji".

"Abullah" proceeded to create Pluto, and inserted Sahad's AI into the robot. Goji went on to create "Bora", another, much bigger robot, which was left underground; his plan was to insert his AI into Bora, and tunnel underground, causing a massive eruption that would destroy the planet.

Atom, who had been left in a similar state to that of Tenma's perfect AI due to an attack by Pluto, is reawakened by Tenma, who inserts a chip containing Gesicht (the main character)'s hatred and a recording of his moment of death (as he was defeated and then destroyed by Pluto). Initially he behaves oddly, but after some time, seemingly reverts to his former self. After learning the whole truth of Gesicht's case, he heads to the source of the cataclysm in hopes of stopping it. He comes face to face with Pluto, who attacks him. At first, Atom is overcome by Gesicht's hatred and attempts to destroy Pluto, citing all the robots he'd killed did not want or deserve death, and rips off Pluto's horns and one of his arms in the process. However, he then hears Gesicht's last words in his mind: "Nothing comes from hatred". Suddenly full of understanding, Atom and Pluto cease their attack on another and proceed to lie down for a few moments. Soon afterwards, Atom goes to disarm Bora, with Pluto (whom Astro has begun referring to as Sahad) at his side. Bora attempts to dissuade Sahad, who rejects him, stating that his father has long been dead, and the AI controlling Bora is nothing more than a fake. He ends up sacrificing himself, saving Atom and the world from the disaster in the process.
