Jetter Mars (ジェッターマルス Jettā Marusu) is an anime series made in 1977, 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.


In the futuristic year of 2015 A.D.Dr. Yamanoue, the leader of the Ministry of Science, has devoted himself to assembling an Android named Jetter Mars on an artificial island and intends to use it as a war machine. But the robot has a deficiency in his electric brain, and he comes to the conclusion that his friend and rival Dr. Kawashimo's help is essential to correct his defective brain. Dr. Yamanoue is very jingoistic and only thinks of the robot as one of his strategic arms. On the contrary, Dr. Kawashimo is a pacifist and devotes his affection to robots. Dr. Kawashimo hurries to the island on request of Dr. Yamanoue, taking his young daughter Miri with him. Arriving on the island, Dr. Kawashimo sets the electric brain into Jetter Mars. Thus Mars comes into the world. Jetter Mars may not know much about the world, but he will always save the day with his powers!

Jetter Mars

Conception and design

Jetter Mars was a series originally meant to be a color remake of Astro Boy. It's Thought that for this reason, Mars seems to be a redesign of the main character of that show: Astro Boy.


Jetter Mars' personality is that of a spoiled child, similar to that of Uran. He's also said to be very dumb, and will often-times do and say very dumb things, and is ignorant of the world around him. He does, however, mature quite a bit throughout the series, especially when his little brother Melchi is introduced.


Miri (美理 Miri) has a design reminiscent of Uran and is likely to be a replacement for her in the Jetter Mars series, as the show was originally meant to be a color remake of Astro Boy. Though she is much more mature than Uran, Uran's immature and rowdy behavior still exists in the form of Jetter Mars, and Uran ends up having to be the mature one, much like the character Astro Boy.


Melchi (メルチ Meruchi) is Mars' baby brother. His design is that of a baby of unknown age. Melchi is playful and careless, though this leads Melchi into causing a lot of trouble, as Melchi is shown to enjoy destroying things! He also often utters a word he made up called Bakaruchi (バカルチ). Melchi's design is reminiscent of the Astro Boy character Chi-tan

Dr. Yamanoue

Doctor Yamanoue (山之上博士 Yamanoue Hakase) is the creator of Jetter Mars. He is a scientist who wants to create robots for warfare and intends to use Mars for warfare purposes. Dr. Yamanoue's design is reminiscent of the character Dr. Tenma.

Dr. Kawashimo

Doctor Kawashimo (川下博士 Kawashimo Hakase) is Mars' co-creator who has created his electronic brain, prior to Mars creation, he also created, Miri who acts as his daughter.
