A robot science fiction manga that was serialized for a long period from 1962 to 1964, starting with the school year magazine "First Grade'' and ending with "Fourth Grade.'' Partly coinciding with the serialization period of the hugely popular Gigantor, the main character, the robot Samson, is controlled by a boy with a remote control like Gigantor, and is a hero manga that fights against evil, and is featured in the front page of each publication in color, a work that received a great response at the time. The story consists of Parts 1 and 2, and this is the first reprint from the original illustrations.
