The Fandom Post is reporting that the Shin Tetsujin 28 anime is now available on Amazon Prime. The series is available for free viewing if you’re a Prime member, and you can also buy episodes for 99 cents each or the whole first season for $20.99.
The story of Shin Tetsujin 28 is described as:
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 some ways, 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.
