• Before making a single edit, Tropedia EXPECTS our site policy and manual of style to be followed. Failure to do so may result in deletion of contributions and blocks of users who refuse to learn to do so. Our policies can be reviewed here.
  • All images MUST now have proper attribution, those who neglect to assign at least the "fair use" licensing to an image may have it deleted. All new pages should use the preloadable templates feature on the edit page to add the appropriate basic page markup. Pages that don't do this will be subject to deletion, with or without explanation.
  • All new trope pages will be made with the "Trope Workshop" found on the "Troper Tools" menu and worked on until they have at least three examples. The Trope workshop specific templates can then be removed and it will be regarded as a regular trope page after being moved to the Main namespace. THIS SHOULD BE WORKING NOW, REPORT ANY ISSUES TO Janna2000, SelfCloak or RRabbit42. DON'T MAKE PAGES MANUALLY UNLESS A TEMPLATE IS BROKEN, AND REPORT IT THAT IS THE CASE. PAGES WILL BE DELETED OTHERWISE IF THEY ARE MISSING BASIC MARKUP.

Bigger than big, taller than tall,

Quicker than quick, stronger than strong;

Ready to fight for right — against wrong!

—The American version's Bragging Theme Tune


Over the buildings he soars

Over the highways he roars


The flying bullets go


And everything explodes


Goes the flying Tetsujin

Number 28, go!
—Rough translation of the Japanese version's Bragging Theme Tune

Gigantor — Tetsujin Nijuhachi-go, or "Iron Man #28" in the original Japanese — was a Humongous Mecha controlled by a young boy, Jimmy Sparks (Shotaro Kaneda). They lived on a remote island with Jimmy's uncle, a scientist, and fought crime. Originally set just after World War II, the English dub portrayed the show as being set in the then-future year of 2000. Based on the original manga by Misuteru Yokoyama, it is one of the first popular anime to air in America, in both its original form and in the revamped New Adventures of Gigantor originally produced in 1980, and aired internationally in the late 80s/early 90s. It was also given a live-action adaptation in 2005.

In late 2009, the city of Kobe in Japan completed a statue of the robot. It is full size, 60 feet tall and weighing in at more than 50 tons. Just looking at it shows how impressive a real-life Humongous Mecha would be.

Gigantor is the Trope Namer for:

  • Shotacon: Shotacon gets its name from Shotaro, who is considered the prototype for the boys found in the genre. It has since evolved, however.

This series provides examples of:

  • Adorably Precocious Child — Shotaro is an excellent example.
  • Alternate History: — At least in the 2004 version, it's mentioned that in 1945 the Japanese attempted a last ditch attempt to stop the Americans by launching the other Tetsujin models on the West Coast. It didn't work.
  • Humongous Mecha — the first.
  • Nuclear Weapons Taboo — In the 2005 series there's the Sun Bomb, powered by an element (Bagume) that can only be kept stable in water, no less.
  • Shout-Out — Anime classic Akira makes a Shout-Out to Gigantor with some character names: Shotaro Kaneda and Akira Shikishima.
  • The Kid with the Remote Control: Possibly the Ur Example, at least in the mecha genre.
  • Red Eyes, Take Warning: In the 2004 series, the Mafia steal the remote control box and are able to control Tetsujin. During this time, Tetsujin's eyes turn red, with no In-Universe explanation as to why.
  • Super Robot Wars: It will show up -at last!- in Super Robot Wars Z 2.2. Though it's the 80s version which has had a mixed reception.
  • Trope Maker — Gigantor created the Super Robot, which Go Nagai's series would expand upon.
  • Twenty Minutes Into the Future — in the Gigantor dub. The original version was set around the end of World War II (or about a decade after it in the 2004 anime), also making it the earliest (if not the first) example of a:
    • Macekre — Eventually inverted by the aforementioned 2004 series, which not only is truer to the original Japanese version (including retaining the characters' original Japanese names), it was even released under the original name of Tetsujin 28 in North America.
  • Product Placement — In the original Japanese version, there's a sponsor spot (just before the opening proper) for the Japanese candy company Glico (makers of Pocky). It goes "GURIKO! GURIKO! GU! RI! KO!" ("guriko" being the Japanese pronounciation.)
