A new series was produced in Japan in 1980 and was later shown as The New Adventures of Gigantor, on the Sci Fi Channel from 1993 to 1997.

[3] The robot is made of steel and has a rocket-powered backpack for flight, a pointy nose, eyes that never move and incredible strength, but no intelligence (although he started to tap his head as if trying to think in one episode).

Originally developed as a weapon by Jimmy's father, Gigantor was later reprogrammed to act as a guardian of peace.

Together, Jimmy and Gigantor battle crime around the world and clash with the many villains who are always trying to steal or undermine the giant robot.

In 1963, Fred Ladd, while working on the animated feature Pinocchio in Outer Space and on the animated TV series The Big World of Little Adam had seen artwork of Mitsuteru Yokoyama presenting a giant robot remote-controlled by a young boy.

[7] It was playing at 7:00 p.m. on New York's WPIX-TV when Variety gave it a particularly scathing review, calling it a "loud, violent, tasteless and cheerless cartoon" which was "strictly in the retarded babysitter class".

The reviewer added that Gigantor was popular; he said, "Ratings so far are reportedly good, but strictly pity the tikes and their misguided folks.

It was described by the TV Week as an "animated science fiction series about the world's mightiest robot, and 12-year-old Jimmy Sparks who controls the jet-propelled giant".

Gigantor was one of a number of Japanese TV series that enjoyed strong popularity with young viewers in Australia during the 1960s.

Old time radio listeners might find the Inspector Blooper sounds a lot like the Willard Waterman/Harold Peary-voiced character "The Great Gildersleeve".

The 1980–81 New Iron Man #28 (Shin Tetsujin-nijuhachi-go) series was created with 51 episodes based on a modernized take upon the original concept art.

In 1993, Ladd and the TMS animation studio converted the series into The New Adventures of Gigantor and broadcast it on America's Sci-Fi Channel from September 9, 1993, to June 30, 1997.
