''Kamen Rider X'' was the third ''Franchise/KamenRider'' series from Shotaro Ishinomori, there was also a manga released around the same time.

However, the latest evil organization Government of Darkness(or GOD for short) wants the invention. Jin's fiancee is a spy for GOD and executes both Jin and his father, but not before Dr. Keitaro manages to SOMEHOW drag Jin Keisuke all the way into his lab and install the engine into him. Dr. Keitaro dies shortly after, but not before leaving his son the gear to become Kamen Rider X! X vows to destroy the Government of Darkness, and avenge his father!
!! This series provides examples of:
* BadassBiker: Rider X of course.
* BadassBystander: The climax of episode 32 takes place inside a restaurant with an African theater group. When the fighting breaks out and the woman with the schematics is cornered, one performer powers through them and easily subdues the GOD mooks.
* {{BFG}}: Apollo Geist has one ''that's attached to his right arm'' and boy it's friggin powerful.
* BlackKnight: Apollo Geist fits this description, only in red armor.
* BloodierAndGorier: Not ''quite'' to Amazon extent in terms of gore, but close, with enemies being sliced in half, decapitated, and impaled. And Jin Keisuke is bloodily executed via machinegun fire in Ep. 1. The manga of X however...is extremely gory at times.
* ByThePowerOfGrayskull: '''SET UP!!'''
** Following [[spoiler:X's upgrade surgery]], '''DAI HENSHIN!!'''
* {{Cyborg}}: The previous two ''Kamen Rider'' series referred to Riders as ''kaizo ningen'' ("modified human"), which has a wider meaning than the usual English rendering "cyborg". This series used the term ''Kaizorg''.
* DarkerAndEdgier: Compared to the two series before, X is much darker.
* DeathByOriginStory: Jin Keisuke (sort of) and his father. His father uploads himself into a computer to help him in the fight against evil, but literally one episode later realizes this is actually holding X back and blows himself up.
* EmergencyTransformation
* EvilTwin: Government Of Darkness Rider (actually a camouflaged monster)
* FakeShemp: Riderman in TheMovie is played by a suit actor, stock footage from the tv show and an uncredited voice actor.
* ForgottenPhlebotinum: In Episode 2, Jin Keisuke suddenly uses a two-barrel blowdart gun. It takes out some attacking GOD minions and even saves the Kid Of The Week from being lynched. In spite of it looking like the coolest thing ever, it is never seen again.
* FunWithAcronyms: The '''G'''overnment '''O'''f '''D'''arkness.
* GettingCrapPastTheRadar: Let's just say the acronym GOD would not fly in many other countries...
** Never mind that when the minions appear from their hiding places, their hands are pressed together like they're praying.
* {{Gorn}}: The manga is filled with it.
* HumongousMecha: King Dark
* LoveHurts: Literally.
* LuckilyMyShieldWillProtectMe: Apollo Geist uses his shield as a weapon.
* TheManBehindTheCurtain: [[spoiler:King Dark's pilot is Dr. Noroi, a former friend of Keisuke's dad. He isn't very impressive by himself.]]
* MidSeasonUpgrade: After X is defeated by Spider-Napoleon, V3 upgrades him. He gains a new transformation pose ("Dai Henshin!") and a new finisher, the Vacuum Hell Wheel.
* MonsterOfTheWeek
* NinjaPirateZombieRobot: Pretty much every kaijin in the second half is an example. The monsters in the second half are combinations of animals and historical figures. Hence you get Scorpion Geronimo, Ant Capone, and, of course, Starfish Hitler.
* NonSerialMovie: [[Film/FiveRidersVsKingDark 5 Riders vs King Dark]]. It's supposedly in continuity due to bringing back Riderman, but can't fit well into the series at any point. Rider X still hasn't been upgraded in the movie, but already knows the Riders, while in the tv show he only meets Rider 2 for the first time after getting his upgrade.
* PunnyName:
** ''Hitode'' is Japanese for starfish, so Starfish Hitler in the original Japanese would be pronounced "''Hito''de ''Hitto''ra".
** One that works in both Japanese and English is [[UsefulNotes/AlCapone Ant Capone]], or "''Ari'' Capone".
* PuttingOnTheReich: Starfish Hitler's GOD Mooks are all dressed in custom uniforms (being some of the few mooks with such radically different clothing) based on the SS uniforms.
* ScarfOfAsskicking: It even has an X on it!
* SmallRoleBigImpact: Professor Nambara is just another victim of GOD, a scientist captured and forced to construct an experiment. However before he's killed, he splits up his blueprints and sends them to his friends, setting up the Macguffin hunt that goes through most of the remaining episodes.
* StoneWall: X-Rider isn't any slower than the other Riders, but he's built to withstand the deepest ocean depths, and is therefore ''very'' sturdy. (The others mostly have stylized chest muscles protecting their torsos - X has body armor.)
** Early on in the series the villains try shooting him repeatedly with machine guns. They stop around the time he walks through a hail of gunfire like Superman.
** Comes to a head in SPIRITS, when a dude punches Keisuke in the face while ''untransformed''... and breaks his hand, while Keisuke just gets a bloody nose which goes away in a few panels.
* StuffedIntoTheFridge: As a hasty means to resolve a story arc, [[spoiler:both Ryoko and Kiriko, Jin's ex-girlfriend turned-traitor and her mysterious twin sister respectively, both die in Episode 8.]]
* StupidJetpackHitler: STARFISH HITLER!!!
* SuperNotDrowningSkills: Subverted. X is made to swim, and has an edge in underwater combat.
* SwissArmyWeapon: The Ridol, which is a combination [[SimpleStaff staff]]/[[WhipItGood whip]]/[[RoyalRapier rapier]].
* ThoseWackyNazis: Starfish Hitler is a walking Nazi stereotype.
* VillainSong: GOD's March, sung by [[NamesToKnowInAnime Koorogi '73]]. A small segment is heard at each title card.
* WeCanRebuildHim: X's origin, and slightly later in the series [[spoiler: how Apollo Geist is resurrected.]]
