The final cour of Tetsujin 28-gou , which aired half a year after the end of the first season.

This theatrical version based on the manga by Yokoyama Mitsuteru, deals with the genius boy detective Kaneda Shotaro and his giant robot, Tetsujin 28, set in Tokyo ten years after the end of the Second World War. Shotaro's missing brother appears as a a new character who was trained as a pilot of the soldier robot Tetsujin which Japan had created for the Second World War. However, with the end of the war, there was nothing left for him but a peaceful Japan. In the meantime, "Destruction Bombs" are found in many places in Tokyo. The bombs were developed by Professor Kaneda, the creator of Tetsujin 28 and Shotaro's father, as the ultimate weapons to protect the mainland. If the bombs explode, Tokyo will be reduced to ashes.

Shortly after pre-teen Shoutarou Kaneda discovers his late father's legacy, a 60-foot-tall, 50-ton remote-controlled robot, he's put in charge of it. Shoutarou accepts the V-controller and duty that his father intended for the giant robot, Tetsujin: to fight evil and keep the peace. As the youngest member of Interpol, Shoutarou’s adventures take him around the world, under the sea, through time, and the deepest reaches of space. His mentors are Dr. Shikishima, his father’s brilliant colleague, and Inspector Ohtsuka, the sometimes buffoonish chief Interpol liaison, but in someways, Shoutarou is closest to his giant avatar, Tetsujin. Together, they battle various menaces, from mad scientists to pirates to ninjas to international criminals, all with their own unique giant robots, but the deadliest villain that Shoutarou and Tetsujin build up to is the Space Demon King, an alien so powerful that he threatens to swallow up the Solar System.
