Tetsujin 28 Go

Tetsujin 28-gō (鉄人28号, Tetsujin Nijūhachi-gō, literally "Iron Man #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, the first in 1963. It was the first Japanese series to feature a giant robot. The 1963 series was later released in America as Gigantor. A live action motion picture with heavy use of computer generated graphics was produced in Japan in 2005.
