Tetsujin 28-gō (Japanese: 鉄人28号, Hepburn: Tetsujin Nijūhachi-gō, lit. "Iron Man No. 28") is a 1956 manga written and illustrated by Mitsuteru Yokoyama, who also created Giant Robo. The series centred on the adventures of a young boy named Shotaro Kaneda, who controlled a giant robot named Tetsujin 28, built by his late father.
The manga was later adapted into four anime TV series, a Japanese television drama and two films, one live action and one animated. Released in 1963, the first series was among the first Japanese anime series to feature a giant robot. It was later released in America as Gigantor. A live action movie with heavy use of CGI was produced in Japan in 2005.
Tetsujin 28-gō (Japanese: 鉄人28号, Hepburn: Tetsujin Nijūhachi-gō, literally "Iron Man No. 28") is a 2004 Japanese anime series and the remake of the original 1960s anime adaptation, animated by Genco and Palm Studio and written and directed by Yasuhiro Imagawa. The series has been released in the United States under its original name by Geneon and in the United Kingdom by Manga Entertainment, the first time a Tetsujin-28 property has not been localized to Gigantor in America or other English speaking nations. While not fully based on the original manga, it followed an extremely different storyline than in the 1960s series.
The story takes place ten years after World War II, approximately the same time as the manga debuted, focused mainly on Shotaro's pursuit to control and fully understand Tetsujin's capabilities, all the while encountering previous creations and scientists from the Tetsujin Project.
