List of ''Astro Boy'' characters

This is a list of characters from the manga and anime series Astro Boy created by Osamu Tezuka.

Major characters

• Astro Boy (Tetsuwan Atomu; "Mighty Atom" in Japanese versions) - The robot boy fashioned after Tobio Tenma (Astor Boynton III in the B/W American translation) by his father, the head of the Institute of Science in the year 2000. Aside from possessing the strength of 100,000 horsepower (later 1,000,000, though these numbers often fluctuate between stories) and the kind personality of a child, he has what are called his "seven amazing powers": jet-powered flight, multilingualism, analytical skills, headlight eyes, super-sensitive hearing, hidden weapons in his back, and the ability to tell if a person is good or evil. In addition, he has a built-in geiger counter and shortwave communication system.
• Uran (Uran)/Zoran/Astro Girl - Atom's robotic sister with a shown adoration towards Atom; she is a superhuman robot with a naive, tomboyish personality. Constructed by Dr. Ochanomizu as a "gift" for Atom, Uran is an extremely mischievous little girl who constantly lands her older brother in trouble. While lacking Atom's weaponry and propulsion systems, she is extremely powerful (50,000 horsepower) and regularly accompanies him on various missions (or attempts to). Like Atom, she is fully capable of experiencing human emotions - though being somewhat less 'mature'. Uran first appeared in Episode 35 (Uran) under the misleading name Astrogirl (due to the fact it sounds more like a female dubbed version of the protagonist; in the manga she has always been known as Uran, although in the 2000 anime series she was renamed Zoran, despite this being a male name). In the 2003 anime and Naoki Urasawa's Pluto Uran has the ability to communicate with animals. In the Canadian version of Astroboy, she is dubbed as "Sarah". Her name is based on uranium, a metal used to power nuclear reactors.
• Dr. Umatarō Tenma (TENMA-hakase; "Dr. Aster Boyton II") - The former head of the Institute of Science. Ever since his son died, he decided to build a robot boy who looks like his son. But when he discovered that Atom could not grow, he sold his son to the circus. He appears only in Episodes 1: Birth of Atom, and 97: Mystery of The Metal Men.
• Hoshie Tenma (TENMA Hoshie) - deceased wife of Dr. Umatarō Tenma and mother of Tobio Tenma. Her facial features are taken from Michi, a superhuman being created from synthetic cells in the manga version of Metropolis. This is quite appropriate as Michi was something of a spiritual predecessor to Atom and in a way could even be seen as his mother. Hoshie was the model for Atom's robotic mother as seen in volumes seven and Eight of the Tetsuwan Atom Manga.
• Professor Ochanomizu (OCHANOMIZU-hakase; "Dr. Packerdermus J. Elefun") - The present head of the Institute of Science and a fearless campaigner for robotic rights. Kind, patient and good-natured, he serves as a mentor for both Atom and Uran, and would willingly give his life for either. Somewhat eccentric by nature, he tends to be excitable when faced by a scientific mystery, particularly when his opinions are questioned by his scientific colleagues. He first appeared in Episode 1: Birth of Atom, where he rescued Atom from Hamegg's circus.
• Police Inspector Tawashi (Tawashi-keibu; translated as "Inspector Hairbrush"; known in English as "Inspector Gumshoe") - a highly placed police detective with an innate distrust of androids and robots (the reason to this is never explained in detail). Due to his opposition to Tokyo's robotic population, Tawashi has a long-standing feud with both Dr. Ochanomizu and Higeoyaji, and frequently engages in volatile arguments with them. While arrogant, cantankerous and, in some cases, downright rude, he eventually comes to respect Atom's courage and abilities, even calling for his assistance in particularly difficult cases. Partnered with Chief Nakamura, he first appeared in Episode 2: Franken.
• Police Inspector Nakamura (Nakamura-keibu; "Chief McClaw") - The chief of the police and the partner of Inspector Tawashi. Played mainly for comic relief, he was normally portrayed as fat, dim-witted and gullible; a stereotype "clueless flatfoot" of the period. Nonetheless, he instantly recognized Atom's good side and frequently stood up for Atom against his bullying partner (as seen in Episode 23). In the 1960s English translations, he has an Irish accent. He first appeared in Episode 2: Franken.
• Shunsaku Ban (BAN Shunsaku; "Albert Duncan") aka Victor (later Percival) Pompous in the first series, Mr. Mustachio (Higeoyaji; "Daddy Walrus") in the second - originally introduced as a private investigator in the first American dub, Higeoyaji played several roles in the Japanese strip series, including school teacher and martial arts expert. Like Dr. Ochanomizu, Higeoyaji serves as a surrogate father for Atom and Uran, providing guidance and advice when necessary. While gruff and comically short-tempered, he harbours a deep admiration for Atom, seeing him as the son he never had, and even stands up to the formidable Inspector Gumshoe in the boy's defence. Higeoyaji first appeared in Episode 7: Denkou. In both the original comic strip and the second 1980s Japanese series, he was Atom's school teacher (in Naoki Urasawa's Pluto he has apparently been promoted to principal), and his nickname was Mr. Mustachio or Daddy Walrus. In the 2003 remake, he is notably absent from Atom's school, working full-time as a private eye and is also the uncle of Ochanomizu's assistant, Yuko Kisaragi.
• Mama and Papa - Atom's robotic parents. Mama is depicted as an idealized 1960s housewife, and she is sweet, kind and nurturing. She is entirely trusting of her son's impeccable nature, knows he would never deliberately lie or harm another being (as seen in Episode 20). In contrast, Papa is portrayed as something of a well-meaning blowhard, often jumping to conclusions and losing his temper over minor incidents. They first appeared in Episode 2: Franken. In the Sankei Newspaper Atom manga series, it is revealed that Mama was modified to resemble Dr. Tenma's wife who had died of a heart condition shortly after Atom was sold to the circus.
• Cobalt (Kobaruto; "Jetto" & later named Atlas in the 1980s' Anime vertsion) - Atom's robotic brother. His origins differ in the continuities of the manga & anime versions. In the manga, he is an inferior copy of Astro created as a replacement by Prof. Ochanomizu when he was missing & presumed scrap. In the anime version, he was a defective prototype of Atom built by Dr. Tenma, then sealed within the Ministry of Science archives & later released. Cobalt has abilities comparable to his brother's, but lacks Astro's intelligence and common sense. Clumsy, accident-prone and gullible, he is a constant source of trouble for Atom's family (and everyone else who crosses his path). Despite these problems, Cobalt is often shown to be extremely kind-hearted and loyal. In addition to the abilities that were copied from Atom, he also shares a kind of telepathic link with his brother that gives him the ability to sense when Atom is in danger & home in his location. He originally died a heroic death at the conclusion of the Midoro Swamp story arc in the Shonen Magazine serial version of the manga, but Tezuka later changed his mind & rewrote the ending for the paperback version so that he survived. He first appeared in Episode 84: Cobalt. However his 1980's anime version portrayal is quite different. He is powerful and super-intelligent (which he was powered by the Omega Factor). His main desire is to get revenge on the humans and world domination. He is encountered by Asto (Atom) several times and would often try to convince his brother to join his cause. It was not revealed they were brothers until Episode 42. He changed his mind regarding humans after Atom begged him to help them fight off the alien invaders. He sacrified himself to destroy the invaders once and for all in Episode 42 and was presumed destroyed along with his Floating Crystal Palace. His name is based on Cobalt-60, an isotope used in nuclear reactors.
• Chi-Tan - Atom's baby brother created by Dr. Ochanomizu and seen primarily in the last season of the anime. Created primarily as a comic relief character. Main characteristic is his loud bawling, which can shatter things. Believed to have been inspired by the character, Swee'Pea from the Popeye cartoons.
• Ken'ichi - Atom's classmate. He's the class president and also the smartest. He first appeared in the manga Episode, Franken.
• The Blue Knight - also known as Blue Bon. He is known to be a hero among many robots for helping those who were treated poorly by humans. As he wears a blue suit armor, people call him "The Blue Knight" out of fear. He also wields a sword that emits an aura that affects certain robots. During a fight against him, Atom realizes that the sword does not affect robots that tend to revolt against human however those that do not will feel tired as he did. He only appeared in one manga episode, "The Blue Knight". In the 2003 anime series his character was expanded and was given a background story line. During his early days as normal robot, he used to work at a robot circus, repairing broken robots who lost in robot fighting matches. When he saw how badly robots were treated in the circus, he decided to take action by helping them all escape; however, he was caught by his human owner, who happens to be the ringmaster of the robot circus and was thrown out into space. He was later found by Shadow who rebuilt him into The Blue Knight. He is portrayed as a crusader for robots and tends to be cold and cruel towards humans, especially those who mistreated robots. He does not listen to anything they say and does not care if he hurts anyone of them whether they are innocent or not because of all the anger that he had in the past.
