''Gigantor'' -- Tetsujin Nijuhachi-go, or "Iron Man #28" in the original Japanese -- is a HumongousMecha controlled by a young boy, Jimmy Sparks (Shotaro Kaneda). They live on a remote island with Jimmy's uncle, a scientist, and [[TheyFightCrime fight crime]]. Originally set just after UsefulNotes/WorldWarII, the English dub portrayed the show as being set in the then-future year of 2000. Based on the original manga by Mitsuteru Yokoyama, it is one of the first popular anime to air in America, both the original form, produced by Eiken Studios (formerly called TCJ), and in the revamped ''New Adventures of Gigantor'' originally produced in 1980 by Creator/TMSEntertainment, and aired internationally in the late 80s/early 90s. The sequel, Tetsujin 28 FX was produced by the same production that created New Gigantor and was aired in 1990s in Japan. It was also remade in 2004 and given a live-action adaptation in 2005. Recently, Tetsujin 28 Gao was produced by the same company that created and animated the first Gigantor series and was aired by 2013.

Tetsujin-28 also has the distinction of being the first HumongousMecha anime in history, predating ''Anime/MazingerZ'' by a solid 10 years, [[UrExample making it the grandpappy of all the mecha series you see today]].

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. [[http://www.crunchgear.com/2009/10/06/japan-finally-completes-its-gigantic-gigantor-statue-video/ Just looking at it]] shows how impressive a real-life HumongousMecha would be.

!!Tropes:

* AdorablyPrecociousChild: Shotaro is an excellent example.
* AlternateHistory: 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.
* BigBad: [[spoiler: Uchuumaou (Moldark)]] in the 80s Series
* BrainwashedAndCrazy: Happened TWICE in the 80s Series
** 21st episode has children becoming mindless child soldiers (cue the helmet they worn is a brainwashing device) of a fancy-dressed lady [[spoiler:or rather a man dressed in that costume]]. Unfortunately, Makie was among them.
** 47th Episode has Shotaro becoming a (temporary) mindless "test pilot" of Tetsujin as part of the Canadian criminal's (Dorombo's) plot to sell Tetsujin.
* DudeLooksLikeaLady: In the 21st episode of the 80s series, the woman in a fancy Chinese suit (the curlpit of abducting and [[Brainwashed brainwashing]] children, including Makie)[[ spoiler: turned out to be a man when the mask was removed]].
* TheFifties: The setting of both the 2004 series and the original anime.
* HumongousMecha: TropeMaker
* TheKidWithTheRemoteControl: Possibly the UrExample, at least in the mecha genre.
* LighterAndSofter: The ''Gao'' series.
* LiveActionAdaptation: The 2005 film.
* NuclearWeaponsTaboo: In the 2005 series there's the Sun Bomb, powered by an element (Bagume) that can only be kept stable in water, no less.
* PantyShot:
** Shown briefly in the 1980s series (particularly Makie's/Bonnie's).
** This also happened in FX wherein one of Masato's (female) friends showed her underwear, depicting a blue-hued original Tetsujin in the back part, to the 2 men.
* ProductPlacement: 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! [[PunctuatedForEmphasis GU! RI! KO!]]" ("guriko" being the Japanese pronounciation.)
* RedEyesTakeWarning: 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 InUniverse explanation as to why.
* ShoutOut:
** The manga and the 2004 version of the series has some amounts of World War II reference. One of these example is the Tetsujin project, which is initiated by Dr. Kaneda,being based on German rocket missles initiated by Werner von Braun.
** Anime classic ''Manga/{{Akira}}'' makes a ShoutOut to ''Gigantor'' with some character names: Shotaro Kaneda and Shikishima. Otomo Katsuhiro was a fan of the series though.
** Dave Mustaine of Music/{{Megadeth}} cited ''Gigantor'' as one of his favorite cartoons and named his tour "Gigan''tour''" in its honor.
* SubmarinePirates: The 15th episode of the 1980 series, ''The New Adventures of Gigantor'' ("The Pirate Submarine").
* TwentyMinutesIntoTheFuture: 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.
* UrExample: Gigantor created the SuperRobot, which Creator/GoNagai's series would expand upon.
* YouKilledMyFather: In the 1980 series where Shotaro's father was killed by Branch (Dr. Murkybottom). This trope was only applied in the 24th episode wherein Shotaro seeks revenge on Branch but [[spoiler: Branch was later abducted by aliens which were actually Uchuumaou's minions]]
* YouGottaHaveBlueHair:
** This is rarely shown in 1980s series (notably, teal-haired Gura/Coldark) and FX (notably, purple-haired Franken).
** ''Gao'' has some amount of color-haired characters. (e.g. Prof. Shikishima in purple-hued hair)
