{{nihongo|Jetter Mars|ジェッターマルス|Jettā Marusu}} is an anime series directed by Rintaro and conceptualized by Osamu Tezuka.{{Cite book |last=森 |first=晴路 |title=図説鉄腕アトム |date=2022-03-15 |isbn=978-4-309-29191-8 |publisher=Kawade Shobo Shinsha|location=Japan |publication-date=2022 |pages=122–125 |trans-title=Tetsuwan Atom Illustrated}} It was produced by Toei Animation and debuted on Fuji TV on the 3rd of February, 1977. The story follows a robot boy named Jetter Mars who must learn the difference between right and wrong under the care of two conflicting parental figures: Director Yamanoue, who wishes to use Mars as a tool for war, and Professor Kawashimo, who believes Mars should be raised similarly to a human boy.

Jetter Mars was conceptualized as an animated television show, but supplemental manga were published alongside the show's run to promote the show. Primarily, Ikehara Shigeto's version of the manga published in TV Land magazine, which had some of its chapters reprinted and compiled into a paperback manga in 2019. {{citation needed|date=May 2025}}

Development

Unlike the vast majority of Osamu Tezuka's characters, Jetter Mars was not first published in comic book form, written and illustrated by Tezuka, but the character does bear physical resemblance to the titular character of Tezuka's previous work, Tetsuwan Atom. Initially, Jetter Mars was planned as a sequel series to Tetsuwan Atom called Mighty Mars (マイティ・マルス Maiti Marusu){{Cite book |last=森 |first=晴路 |title=図説鉄腕アトム |date=2022-03-15 |isbn=978-4-309-29191-8 |publisher=Kawade Shobo Shinsha|location=Japan |publication-date=2022 |pages=122–125 |trans-title=Tetsuwan Atom Illustrated}}

In the original pitch written by Osamu Tezuka, Dr. Ochanomizu wished to rebuild Atom after the events of the final episode of the 1963 version of the Tetsuwan Atom anime. Dr. Ochanomizu seeks out Dr. Tenma, who has isolated himself on Mars. Ochanomizu begs Tenma to rebuild Atom, but refuses. Instead, Dr. Tenma shares blueprints for a new robot: "Mighty Mars", who Ochanomizu would name in honor of Tenma who isolated himself on Mars. Mighty Mars would have all of Astro Boy's abilities, but amplified. he'd also be more human than Atom was. His more human-like nature leads to trouble, as he can act selfish. He makes mistakes, causes trouble, and is tempted by others. The pitch script compares this aspect of Mars' character to Pinocchio.{{Cite book |last=森 |first=晴路 |title=図説鉄腕アトム |date=2022-03-15 |isbn=978-4-309-29191-8 |publisher=Kawade Shobo Shinsha|location=Japan |publication-date=2022 |pages=122–125 |trans-title=Tetsuwan Atom Illustrated}}

In the end, the Astro Boy aspects were removed and Mars' backstory changed with it. {{Cite book |last=森 |first=晴路 |title=図説鉄腕アトム |date=2022-03-15 |isbn=978-4-309-29191-8 |publisher=Kawade Shobo Shinsha|location=Japan |publication-date=2022 |pages=122–125 |trans-title=Tetsuwan Atom Illustrated}} Mars' name would be changed to Jetter Mars and the origin of his name would change to him being named after the roman god of war, Mars. Rather than having all of Atom's abilities, Jetter Mars' abilities would be stripped down to super strength, flying, searchlight eyes, and super hearing.

Some episodes of Jetter Mars closely mirror that of classic stories Tezuka wrote and drew in his Tetsuwan Atom manga, with The Artificial Sun being the most blatant, replacing the Sherlock Holmes parody with a James Bond parody and replacing the artificial sun with a cryogenic freezing device. The Artificial Sun withstanding, episodes mirroring Tetsuwan Atom stories mix in or introduce many new elements into the stories, significantly changing the story and creating something more original than might be expected, sharing only similar characters and/or moral lesson.

In the Tezuka tradition, the series showcased many of his characters from his various manga works in different roles.

In the same manner he wrote and illustrated his Tetsuwan Atom manga, Tezuka stayed away from graphic violence in Jetter Mars, although the typical traits of his works are also present in it, such as the importance of moral values, humanity.

The series was received by Japan's population with mixed feelings, as some wanted the original Tetsuwan Atom and some accepted Jetter Mars wholeheartedly as a different character, as it was intended to be. This made Tezuka to lose interest in the series {{citation needed|date=May 2025}} and it finished with 27 episodes produced.

Plot

The story is set in the future, the year 2015. Two scientists, Professor Kawashimo and Director Yamanoue, have constructed a highly sophisticated robot. Professor Kawashimo created his highly advanced artificial intelligence, gifting him with the personality of a young boy, and the capacity to learn and grow. While Director Yamanoue designed the robot's body, which was constructed by the Ministry of science and endowed with astoundingly powerful abilities. Director Yamanoue names the robot Jetter Mars, taking him into the care of the Ministry of Science. Professor Kawashimo and Director Yamanoue are at odds with each other regarding the purpose of Mars' creation and how he should be raised. Director Yamanoue designed him to be a tool of war and insists on training him as such, while Professor Kawashimo programmed his AI to behave like a normal boy. Mars himself seems to struggle with these two sides of himself, enjoying acts of destruction and mischief and feeling bad when it ends up hurting people. With the help of Professor Kawashimo and his kindhearted robot daughter Miri, whom Mars has taken a liking to, Mars will learn kindness and beauty. From his father, Director Yamanoue, Mars will train for battle, and learn to use his destructive abilities. It's up to Mars which one he decides to indulge in.

As expected from Osamu Tezuka, he put his "character acting company", known as Star System, to use to define the cast of Jetter Mars. He created a few of the characters specifically for the series, such as Mars and Melchi, and the vast majority of the cast was classic and well-known characters from Tezuka's works, playing various roles. In the adjacent picture, it is possible to identify many of Tezuka's characters, from left to right: Daidalos, Shunsuke Ban aka Higeoyaji and Tezuka himself in the upper row; Inspector Tawashi, Rock Holmes and Marukubi Boon in the middle row; and Tamao, Shibugaki, Spider, Chief Nakamura, HamEgg, Acetylene Lamp, Ken'ichi and Hyōtan-tsugi in the lower row; among some others.

The following list describes the characters featured more prominently during the series:

{{nihongo|Jetter Mars|ジェッターマルス|Jettā Marusu}}: The protagonist of the series. A powerful robot built in the image of a boy, he has a body that can be used for destruction of cataclysmic proportions, and a near-human artificial intelligence. Mars was designed as a machine for war, and thus named his creation after the Roman god of war. He finds himself often in the predicament of needing to find a balance between his boy heart and overwhelming strength.

{{nihongo|Melchi|メルチ|Meruchi}}: Mars' younger brother, with the body of a baby. Endowed with tremendous physical strength, his only word is {{nihongo|"Bakaruchi!"|バカルチ|Bakaruchi}} (a word invented by Tezuka with no real meaning). He will also, however rare, speak a sentence.

{{nihongo|Miri|美理|Miri}}: A robot made in the image of a young girl by Dr. Kawashimo. She possessed powers that enabled her to restore destroyed robots and machinery. She is the sister of Mars and Melchi, and daughter to Dr. Kawashimo.

{{nihongo|Dr. Kawashimo|川下博士|Kawashimo Hakase}}: Creator of Jetter Mars' artificial intelligence and heart, and creator of Miri and Melchi. Opposing fellow scientist Dr. Yamanoue, he desired Mars to live a life of good purpose and peace.

{{nihongo|Dr. Yamanoue|山之上博士|Yamanoue Hakase}}: A renowned roboticist responsible for designing Mars. Mars looked up to him as his father. He disappears after the testing of a new gravity weapon.

{{nihongo|Dr. Tezuka|手塚博士|Tezuka Hakase}}: In many of his works, Tezuka drew himself as a character, immersed in the universe of his creations, and interacting with his characters. He was included in the Televiland manga adaptation as a famous roboticist Dr. Yamanoue sees as a rival.

{{nihongo|Spider|スパイダー|Supaidā}} and {{nihongo|Hyōtan-tsugi|ひょうたんつぎ|Hyōtan-tsugi}}: Two cartoonish characters which briefly appear as comic relief. Hyōtan-tsugi usually appeared falling in front of a character at the most inappropriate of times, and getting kicked out angrily by them, and Spider usually appeared in moments of tension, uttering his trademark phrase, {{nihongo|Omukae de gonsu!|おむかえでごんすﾞ|Omukae de gonsu}}, roughly "Here ta meet ya!". Additionally, Hyōtan-tsugi appeared in each episode during the end credits sequence. Spider appears only in the manga and the opening of the Jetter Mars anime.

{{nihongo|HamEgg|ﾊﾑｴｯｸﾞ|Hamueggu}}: One of Tezuka's most recognizable characters in his Star System. As usual, he is up to no good in Jetter Mars, running a robotic circus. In the anime, he tricks Mars into performing for his circus, but in the manga, HamEgg tricks Mars' little brother, Melchi, into joining the circus instead. Both of them end up sapped of their energy due to HamEgg being upset at them.

Episode list

The series had 27 episodes, each lasting approximately 24 minutes. It was broadcast by Fuji TV, on Thursday nights. As with all Tezuka's works, the series made use of his Star System cast, featuring many of his characters from previous works (manga or animated) performing various roles.

At first, they try to make Mars study to become a robot that helps commit crime. Meanwhile, Dr. Kawashimo and Miri decide to look for Mars. Miri follows Mars' signal to the ship. When Mars learns that they are going to make him study, he causes chaos and attempts an escape. But he is stopped by the ship's electromagnetic barriers, which paralyze him. The Robot Trafficking Ring decide that they're better off selling Mars as scrap. Luckily, Miri saves him just in time. The two escape into the sea. Mars learns from Miri that as he was about to be scrapped, he felt fear. Mars redirects missiles that were shot at them into the boat. The coast guard then arrives and take them home.

At that moment, a pair of villains make themselves known, demanding the dog back or they'll detonate the bomb. Miri and Kawashimo go out to look for Mars, finding him at the lighthouse. They insist they'll take the bomb out of the dog and just as Mars is about to come down, the villains interrupt. Mars flies down and handily defeats them all. A small ship lands nearby and a voice from it demands MArs put the dog in the ship or it'll explode, taking Miri and Kawashimo out, too. Mars obliges, before suddenly turning around and bolting into the ship to join his dog. He goes to the pilot chair to confront the villain, but it's a dummy with a speaker. The speaker tells Mars he's going to blow Mars up with the ship. Mars falls back and hugs his dog, content to die with him. But the dog acts up and starts attacking Mars, pushing him out of the ship before exploding. When Mars wakes up, he doesn't remember a thing. Director Yamanoue erased his memory. Kawashimo recognizes this as probably being for the best.
