Jetter Mars (ジェッターマルス, Jettā Marusu) is an anime series directed by Rintaro and written by Osamu Tezuka. Originally planned by Tezuka as a full-color remake of the original anime adaptation of his popular manga series Astro Boy, unfavorable circumstances during the pre-production phase of the project led him to abandon it temporarily and create Jetter Mars instead. Although it remains as one of Tezuka's lesser known works, it gained a large following and is fondly remembered.


Unlike the vast majority of Osamu Tezuka's characters, Jetter Mars wasn't first published in comic book form, written and illustrated by Tezuka. In 1977, Tezuka's animation studio Mushi Productions faced bankruptcy, leading Tezuka to work as an animation director for Toei Animation for some time. He wanted to produce a color anime adaptation for his landmark manga Tetsuwan Atom, (known to western audiences as Astro Boy), but due to the financial distress of Mushi Productions, the copyrights on some of his characters were in limbo. Due to the deadline imposed on Tezuka by Toei to produce the new series, he wasn't able to secure the copyrights to his characters on time, which forced him to compromise his original project and redesign it somewhat, reworking it conceptually and visually to some extent.

Tezuka then redesigned Atom slightly, and renamed him as Jetter Mars. Some aspects of Atom's original story are taken and used as the origin of Mars, such as him being created as a powerful android in the image of a boy. Two scientists are involved in Mars' creation, one conceiving him as a combat instrument and the other opposing that purpose, conceiving him as an instrument for peaceful pursuits. This element mirrors the disagreement found in the characters Dr. Tenma and Dr. Ochanomizu in Tetsuwan Atom. Some other borrowed concepts can be found across the series.

Some storylines in the episodes of Jetter Mars were remakes of classic and beloved stories Tezuka wrote and drew in his Tetsuwan Atom manga, such as The Artificial Sun and The Last Day on Earth. The series was beautifully animated, and in the Tezuka tradition, it 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 and strong emotiveness.

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 lose interest in the series and it finished with 27 episodes produced. Having successfully secured the copyrights on all his characters once again, Tezuka founded Tezuka Productions a few years later, and was able to produce the color anime adaptation of Tetsuwan Atom as he wanted initially, which became a hit, much in the same way as the original anime adaptation from the 60's.


The storyline is set in the year 2015. Two scientist, Dr. Kawashimo and Dr. Yamanoue, have created a robot with advanced capabilities. Dr. Kawashimo created his miraculous artificial intelligence, making him almost human, while Dr. Yamanoue created the robot's body, endowing him with astoundingly powerful weaponry.


The series featured many of Tezuka's most well-known characters, as well as some specifically-created ones.

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:

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. He finds himself often in the predicament of choosing to use his gifts for pacific or destructive purposes.

Melchi (メルチ, Meruchi): Mars' non-speaking younger brother, with the body of a baby. Endowed with tremendous physical strength, his only word is "Bakaruchi!" (バカルチ, Bakaruchi) (a word invented by Tezuka with no real meaning), which he always utters after displaying his power.

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. Protector of Mars and Melchi, and "daughter" to Dr. Kawashimo.

Dr. Kawashimo (川下博士, Kawashimo Hakase): Creator of Jetter Mars' incredible 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.

Dr. Yamanoue (山之上博士, Yamanoue Hakase): Creator of Mars' body. He designed him as a machine for war, and thus named his creation after the Roman god of war. Mars looked up to him as his father. He disappears after being buried during atomic tests and is left for dead.

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 interacted with his characters. He included himself also in Jetter Mars, appearing as friend and advisor to Mars.

Spider (スパイダー, Supaidā) and Hyōtan-tsugi (ひょうたんつぎ, Hyōtan-tsugi): Two cartoony little characters, that appeared whimsically in nonsensical situations, as comic relief. Tezuka's signature, they appeared in all of his works, be it manga or animated, as they were a form of dialogue between Tezuka and his readers, developed during the years. 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, repeatedly uttering his trademark phrase, Omukae de gonsu! (おむかえでごんず, Omukae de gonsu), roughly "Here ta meet ya!". Additionally, Hyōtan-tsugi appeared in each episode during the opening intro and end credits sequences.

HamEgg (ハムエッグ, Hamueggu): One of Tezuka's most recognizable characters in his Star System, he appeared playing non-praiseworthy roles, as usual for him.

Episode list[edit]

The series had 27 episodes, each lasting 24 minutes approximately. Broadcast by Fuji TV, on Thursday nights. As with all Tezuka's works, the series made use of his Star System cast technique, featuring many of his characters from previous works (manga or animated) as guests performing various roles. The following list includes the episode title, airing date and guest characters.[1] [2]
