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. Plot The storyline is set in the year 2015. Two scientists, 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. Characters 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.

He finds himself often in the predicament of choosing to use his gifts for pacific or destructive purposes. : Mars' non-speaking younger brother, with the body of a baby. Endowed with tremendous physical strength, his only word is (a word invented by Tezuka with no real meaning), which he always utters after displaying his power. : 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
