''Neo-Human Casshern'' (新造人間キャシャーン, ''Shinzou Ningen Casshern'') is an anime produced in 1973 by Creator/TatsunokoProduction.

Dr. Kotaro Azuma was creating androids when his prototype, BK-1, went out of control, escaped, and created a robot army which he led to conquer the Earth. The doctor's son, Tetsuya, rebuilt himself as "Casshern", an incredibly strong and agile robot who devotes his new existence to hunting down and destroying the Andro Army of BK-1, now styling himself the "Braiking[[note]]based on a Japanese word meaning "rogue" or "brute"; frequently mistranslated as "Black King"[[/note]] Boss". Casshern was distinguished by not usually using weapons in his fights; he literally tore the Braiking Boss' MechaMooks apart with his bare hands. His companions are '''Friender''', a robotic dog able to transform itself into various vehicles, and '''Luna Kozuki''', a plucky young woman whose scientist father gave her an anti-robot pistol.

''Casshern'' has been {{Retool}}ed several times since the original:
* 1993 had a 4-episode {{OVA}} rebooting the franchise simply titled ''Casshern''; Creator/StreamlinePictures released an English dub under the title ''Anime/CasshanRobotHunter'' as a CompilationMovie.
* In 2004, a LiveActionAdaptation titled ''Film/{{Casshern}}'' was released. This version has Casshern and Braiking Boss -- "Burai" here -- as {{Artificial Human}}s born from Dr. Azuma's research into [[AppliedPhlebotinum artificial stem cells]] to fight the disease caused by the aftermath of a fifty-year war between a {{Commie Nazi|s}} Asian Empire and "Europa". It drew attention for the stylized visuals and impressive action scenes as soon as footage was released. The themes of the futility and dehumanization brought about by war added spice, but the DarkerAndEdgier tone, shameless use of DeusExMachina to move the plot, and [[GainaxEnding esoteric ending]] dimmed enthusiasm once the film was released.
* 2008 brought another reboot called ''Anime/CasshernSins'', which has its own page. This incarnation {{Retool}}s everything about the franchise except the BroadStrokes of the character designs and Braiking Boss conquering humanity, and then veers off to examine the nature of life, mortality, and redemption -- while providing the audience with beautifully animated robotic dismemberment in the process.

Casshern was also one of the characters to appear in the {{fighting game}} ''VideoGame/TatsunokoVsCapcom''.

Along with ''Anime/ScienceNinjaTeamGatchaman'', the show will receive an american DVD release by Creator/SentaiFilmworks.

* AfterTheEnd
* ArtificialHuman: Casshern; it's right in the title.
** Though it should be noted that while the body is artificial, the mind is that of [[VirtualGhost Tetsuya Azuma, a human]].
* BareFistedMonk: Casshern. [[AllThereInTheManual Some sources]] claim that this is because he was a skilled athlete and fighter as a human, and that [[EmpoweredBadassNormal skill was enhanced when he became an android]].
* DieselPunk: The atmosphere/setting of the live-action adaptation.
* DrillTank: Friender is able to transform into a tunneling tank with a big drill on the front.
* JetPack: In the original, Casshern mostly used the twin pistols on his hips as one of these; other adaptations make them into more straight examples of this trope.
* MechaMooks
* MechaShow
* NiceHat: Braiking Boss's hat.
* ThePowerOfTheSun: Casshern's limited power supply can only be recharged this way.
* RobotDog: Friender
* RobotWar
* ShellShockedVeteran: In the live-action movie, Tetsuya joined the Asian Empire military to prove himself, and was killed in action. After being revived as Casshern, [[spoiler:he experiences post-traumatic flashbacks to his wartime experiences, including the atrocities he committed.]]
* SpiritualSuccessor/ SpiritualLicensee : If you want to play a game about this anime, go no further than VideoGame/MegaMan. You play as the robot son[[note]]Unlike Casshern, though. Mega Man, AKA: Rock, was a robot to begin with; he's really more like [[Anime/AstroBoy Tetsuwan Atom / Astro Boy]] then Casshern.[[/note]] of a scientist, who must fight against an evil doctor and his army of robots, with your robot dog (beginning with the third game), your sister and your (sometimes bad, sometimes good) prototype brother.
* SpellMyNameWithAnS: Casshan or Casshern; Braiking Boss vs Black-King (Boss). (''Anime/CasshanRobotHunter'' takes these into the realm of the DubNameChange).
* TransformingMecha: Friender transforms into either a CoolPlane or a [[TankGoodness tank]].
* VirtualGhost: Tetsuya Azuma, aka Casshern.
* WeCanRebuildHim: [[spoiler: done to ''the dog,'' whose ensuing badassitude led Tetsuya to think "maybe doing the same to a human can level the playing field." Unlike most series like this, Tetsuya's upgrade was not an EmergencyTransformation, but quite a sacrifice - he chose to exchange his human body for a mechanical one because he saw it as the only way to fight back.]]
