Astro Boy (アストロボーイ・鉄腕アトム, Asutoro Bōi: Tetsuwan Atomu, lit. "Astro Boy: Mighty Atom") is a remake of the 1960s anime series of the same name created by Osamu Tezuka. Produced by Tezuka Productions, Sony Pictures Entertainment Japan, Dentsu, and Fuji TV, it was directed by Kazuya Konaka, with Marc Handler and Joe D'Ambrosia handling series scripts, Shinji Seya designing the characters, Shinji Aramaki and Takeshi Takakura designing the mechanical elements, Keiichirō Mochizuki serving as chief animation director, and Takashi Yoshimatsu composing the music. The anime was created to celebrate the birthdate of Atom/Astro Boy, as well as the 40th anniversary of the original TV series. It kept the same classic art style as the original manga and anime, but was renewed and modernized with more lush, high-quality, near-theatrical animation and visuals. It combined the playfulness of the early anime with the darker, more serious and dramatic science fiction themes of the manga and the 1980 series. Though many episodes of the series can be regarded as "standalone" in as much as they do not have anything to do with the series' major story arcs, the anime can be regarded as having a well-defined beginning, middle and end. Although the anime appears to initially have two main plotlines - Dr. Tenma's eventual plans for Atom to evolve and another plotline about robot rights - these two story arcs dovetail toward the end of the series.

The anime was broadcast in Japan on Fuji TV from April 6, 2003 to March 28, 2004, every Sunday from 9:30 to 10:00 JST, for a total of 50 episodes, and it was also aired outside of Japan on Animax and other local broadcasters overseas, including Southeast Asia, South Asia, East Asia, and other regions.

The anime won the award for best work in the Television Category at the 2004 Tokyo International Anime Fair.


The show is set in 2043, where robots are common part of humanity's lives. In Metro City, the renowned Dr. Tenma disappears after trying to construct an AI robot with a "heart." Dr. Ochanomizu replaces Tenma as head of the Ministry of Science and discovers a boy-like robot and brings it to life and names him Atom (Astro). He soon discovers he can fly via rocket boosters in his hands and feet, and has superhuman strength and other such abilities, and must deal with robots and villainous robot-hating humans who threaten his friends, fellow robots and Metro City, becoming a hero in the process. Atom quickly learns he is a robotic duplicate of Dr. Tenma's dead son Tobio, and was shut down after seeing how discarded robots were dealt with by his father, an incident similar to what Tobio experienced before dying.

A new arc occurs with the introduction of the Blue Knight, a gallant robot who starts a campaign to free all robots from mankind. Another recurring character, Acetylene Lamp, goes slowly paranoid about the destruction of all robots and becomes a major antagonist of the series. In the final episodes, the Blue Knight declares a new nation for robots, Robotania, located on Antarctica. Lamp deceives the public into believing a house robot pushed a young girl down a flight of stairs (when he did not), and the girl's father, General Red, declares war on Robotania. Most of the core cast becomes involved in the goal to stop the war between man and machine, until Atom convinces the Blue Knight that humans and robots can be friends. The Blue Knight departs Earth on Robotania, which is revealed to be a spacecraft. However, Lamp, who is still paranoid (despite the fact the robots have stopped their crusade against humanity), tries to destroy the spacecraft with a missile, but Atom blocks the attack and is seemingly taken offline.

Dr. Tenma manages to restore him, but erases his memories as Atom so that he can remain "Tobio" forever. Eventually, his memories are restored by his friends from school and his sister, Uran. In one final attempt to reclaim his lost son, Dr. Tenma goes to a laboratory in the Ministry and tries to convince Atom to join him in ruling the world but the latter refuses. Dr. Tenma wants to end his suffering by taking his own life, but Atom embraces and forgives him, causing Dr. Tenma to break down and embrace his son. Dr. Ochanomizu and the robotic police come to the rescue, and Dr. Tenma is willingly arrested and sent to prison. At the end of the series, Atom and Tenma and humans and robots start happily fresh and moving on. Humans and robots come closer together, and Atom appears to shed tears at the conclusion of the series.


The anime was created to commemorate Atom's birthday, April 7, 2003, as established in the original story. Therefore, the broadcast start date was also set to April 2003. The base of the series is different from the original Astro Boy, as it is more of an epic drama with various episodes depicting the coexistence, confrontation, all-out conflict, and reconciliation between robots and humans in a grounded and serious way. The series has a strong retro-futuristic style that is closer to American cartoons than Japanese animation, and some episodes were written by American scriptwriters. Kazuya Konaka, the director of the anime, testified that the American side had a different perception of Astro Boy as a bright and cheerful action-adventure in black-and-white animation, and had doubts about a story with a serious theme like the original.

The series is also a parent-child drama between Dr. Tenma and Atom, and there are several episodes related to other parent-child and pseudo-parent-child relationships. In terms of the setting, many aspects were drastically changed for the family audience. Shinya Owada, who plays Dr. Tenma, was a fan of Astro Boy. Although the series was produced in a 16:9 aspect ratio, it was broadcast in 13:9 at the request of the TV station.

The director, Kazuya Konaka, was a live-action director with no experience in animation, but he was hired because he had directed the 1996 live-action direct-to-video Black Jack film. Although Konaka was unsure about participating in an animated series, he decided to take part in the project because it was a chance to visualize Tezuka's representative work, and he said that he was able to produce the anime with the support of the excellent staff, including animation director Keiichirō Mochizuki. Many of the scriptwriters on the Japanese side worked on the Heisei Ultra series, in which Konaka also participated, but Konaka said that the scriptwriters were a natural group of people from the generation who had a strong attachment to Tezuka's works, and that Hirotoshi Kobayashi and Sadayuki Murai had known each other from outside the Ultra Series. Tezuka Productions wanted to keep the series on 35mm film, while Konaka wanted to use 3DCG, so they stuck to the already dwindling cel production method with a mix of 70% traditional and 30% digital animation.

Mari Shimizu, who had been the voice of Atom since the first anime, gave up the role on April 6, 2003, the day the first episode aired, so Makoto Tsumura took over the voice for this series.

In 2001, a promotional pilot film for the series was released, which featured early concepts for characters and settings. It contained animation exclusive to the trailer, different designs for characters such as Atlas, and an English dub featuring in-house Sony Pictures voice actors. The trailer was made to promote the upcoming series and to raise international interest. Some of the animation featured in the film was eventually repurposed for the opening animation of the final anime.

He is arrogant, self-centered, and extremely misanthropic, and is described as "loving no one" not only by Atom but also by his late son, Tobio. When he was the Director General of the Ministry of Science, he started to develop an intelligent robot to replace Tobio, who died in an accident, and created Atom, but as Atom's mind gradually grew, he began to rebel against himself. As a result, he dares to take Atom to the Seventh Plant, which processes discarded robots, in order to test him. Fearful of the growth of robots with minds, Dr. Tenma uses the "Kill Ring" to force Atom to shut down his system, and then goes on a rampage to destroy all the robots with minds that were under development. This eventually brought him into conflict with Dr. Ochanomizu, and he was expelled from the Ministry of Science. Later, after seeing Atom being rebooted by Dr. Ochanomizu and evolving through the growth of his mind, he came to the conclusion that evolved robots have the potential to surpass humans as a species, and became obsessed with the crazy dream that his robots, including Atom, would rule the world, and turns into a mad scientist. In order to develop Atom into the most powerful robot, he creates his own alter ego, the robot Shadow, and through him causes various incidents in an attempt to make Atom the king of robots and himself the god of robots.

At first, he follows Dr. Tenma's instructions and causes a lot of chaos, but as he watches Atom's battles, he begins to change his mind. He was the one who converted Blue Bon, who had been working as a repair robot for Ham Egg, into the Blue Knight, and was also his shadow collaborator. However, Shadow understood that conflict would cause unnecessary sacrifices, and in contrast to the Blue Knight, he was thinking of creating an ideal world for robots through a method other than war. During the Robotania riots, his true face under the mask, which was initially bare of machines, became the same face as Dr. Tenma's, and he began to rebel against Dr. Tenma. After the reconciliation between Atom and the Blue Knight, he activated the giant spaceship function of Robotania and traveled to the outer solar system with the Blue Knight and the people of Robotania.

Dr. Katō (Dr.カトウ)
Voiced by: Takehito Koyasu (Japanese); Wally Wingert (English)
An insane bomber who believes that destruction is the highest art form, and a former researcher at the Ministry of Science. He works with Lamp, but is not interested in anti-robotism, only in explosions. He is usually uncommunicative, but when he is dressed as a clown in holographic recordings, he becomes frenziedly cheerful. In the end, he uses aerial mines to stop Lamp from going to the South Pole, but the mines are shut down when Inspector Tawashi destroys the control switch. He himself was seized by police robots and arrested. At this time, his trademark sunglasses were removed, revealing for a brief moment his full face with its delicate features.
Katari (加田里)
Voiced by: Rikiya Koyama (Japanese); Wally Wingert (English)
An extremist member of an anti-robotist group. He and Lamp want to drive the AI robots out of the city. He pretends to be various people to drive the AI robots crazy, and shows them to the people to appeal the dangers of robots. He is a selfish and outrageous terrorist who is willing to sacrifice unrelated people and even Mimi (voiced by Yūko Miyamura), a girl who adores him, in order to ruin the reputation of AI robots. In the manga adaptation by Akira Himekawa, he is a former chef who lost his job because of the robots, so he resents them and causes a flood, just like in the anime, but he himself gets caught in the flood and is saved by Atom. After that, he conspires with Lamp and Katō to blow up the Tokugawa conglomerate's lunar plant, but Atom and Atlas intervene, putting them at a disadvantage. At this point, Lamp gives up on him because "his face is too well known," and he teaches Atom and Atlas how to deactivate the detonator while self-deprecating that he is "just a tool."
Rock Holmes (ロック・ホーム, Rokku Hōmu)
Voiced by: Fumiya Fujii (Japanese); Wally Wingert (English)
A psychic and criminal genius. He can manipulate any living thing at will, and is also a master of disguise, changing his appearance many times. With the power of the Firebird (see below), he evolves into a superhuman, and makes a dark move to become the king of the world. He deceives and uses Atom many times and breaks his heart. He is vile and self-centered, but because he is lonely and has no family, he puts a picture of a woman cut out from a magazine on the side of the road on his pendant and thinks it is his mother. In the past, he was subjected to special training, similar to human experimentation, at the ability development laboratory of a rebel organization that was trying to overthrow the government, and escaped at the age of 12. At that time, he was given a false memory that he was abandoned by his parents, which is the reason why Rock hates humans. Using Atom's energy, he summons the Moon Tower to Phoenix Island and tries to gain the power of the Firebird, which brings about evolution, but his evil heart causes it to run amok. He was saved by Atom, and at that time, Rock and Atom learned, through the power of the Firebird, the fact that his mother was too sick to live for long and that he would have been loved if he had not been abandoned, and was eventually arrested by the police.
Ham Egg (ハム・エッグ, Hamu Eggu)

A critic, company president, politician, and anti-AI roboticist. He is a human supremacist who does not accept any intelligence other than human. He has entered the world of politics and has become the spearhead of the anti-AI robot movement. Inwardly, however, he is tormented by PTSD (or rather, pangs of conscience) over having abandoned his robot named Friend who once saved him. He barely keeps his sanity by telling himself and spreading the word that "robots are tools, they don't need a heart." There was an instance that foreshadowed his reunion with Friend, but his attitude remained unchanged after that. Although he created the start of the Robotania riot and planned to eliminate robots completely, his plan failed due to Atom's persuasion of Robotania. However, not wanting to give up, Lamp tries to shoot down the Robotania spaceship boarded by the Blue Knight and Shadow with a large missile from his personal battleship, but this also ends in failure due to Atom's success.

The 2003 version of Astro Boy was extremely well reviewed by Zac Bertschy of Anime News Network, receiving a grade of A+ in every category and comments of, "It's perfect."

Anthony Brzenican of USA Today criticized the series for not having the same optimistic tone of the color 1980s version of the series and eliminating several or changing the personalities of several major characters.

The show did not meet with commercial success during its run on Kids WB! and on Cartoon Network's Toonami block, a fact that is hinted at during the review for the tie-in game Astro Boy: Omega Factor with comments such as, "Astro Boy [didn't receive any] love here in the States". This has been largely attributed to the quality of the dub and the constant moving of the show between the two stations. It has been suggested the show was done in by removing the original's comical co-stars, particularly Chief Nakamura and Astro Boy's robot parents. That, plus the general switch of the show's visuals from childish simplistic to near 3-D complexity, and the name changes for so many of the main characters (from Uran to Zoran and Dr. Elefun to Dr. O'Shay) were deemed by the older fans to be unnecessary for a formerly plot-driven show.

The series, however, had more success in the UK where it was picked up by the BBC for its children's block and digital only children's channel from 2003 to 2006. The show's first run lasted about as long as the US one (up to the 2-part episode featuring Pluto) after which the BBC stopped airing new episodes. This may be because (as one presenter commented after an episode) Astro was a darker show compared to the other cartoons CBBC aired (even in its edited state). The western dub has never been aired fully on TV in the US. Despite how well Astro may have fared in the UK airing and DVDs being advertised, the series has not been released on DVD in the UK. CBBC finished airing recently unaired episodes of Astro Boy, thus completing the entire series in the UK, making Astro Boy one of the rare anime that airs in the UK in its entirety while not doing so in the United States.

In North America, Astro Boy was released on DVD in one single box set by Sony Pictures Home Entertainment in its US edited form. On May 5, 2015, Mill Creek Entertainment re-released the US edited complete series on DVD in Region 1. On May 2, 2019, Mill Creek Entertainment re-released the series yet again with different cover art and a slipcover.

The series was once part of children's programming on television station CVM Television in Jamaica, before it disappeared in 2014.
