Gigantor (鉄人28号, Tetsujin 28-gō, literally "Iron Man #28") is a manga by Mitsuteru Yokoyama that was first published in 1956 and was later adapted into several anime series, the first in 1963. It was the first "giant robot" series. A live action motion picture with heavy use of computer generated graphics was produced in Japan in 2005 based on the old comics as opposed to the newer version in "New Gigantor" which was translated into many languages.
