"I am the child of the sun! Kamen Rider! BLACK! R! X!!"

Kamen Rider BLACK RX is the ninth TV series in the Kamen Rider franchise and, unusually for the series, a direct sequel to the previous series, Kamen Rider BLACK. It was broadcasted from 1988 to 1989 and was the last TV series aired during the Showa-era before the transition to stand-alone movies throughout the 90s.

Six months after being practically left alone at the end of Black, Kotaro Minami has finally gotten on the road to a normal life. He's been adopted by the Sahara family and has a steady job as a helicopter pilot.

However, a new threat to the peace of Earth comes in the form of the Crisis Empire, which seeks Earth as their new invasion target. Acknowledging Kamen Rider BLACK as a threat, they capture Kotaro while preventing his transformation and attempt to goad him into joining the Empire. Kotaro refuses, and as a result he has his King Stone destroyed and gets thrown off to space.


The sun's radiation, however, resurrected Kotaro's Kingstone and split it into two. Thus, Kamen Rider Black evolved into Kamen Rider BLACK RX. It also resurrects the destroyed Battle Hopper, upgrading it into Acrobatter. Now, Kotaro must use his new powers to defend Earth from the Crisis Empire, consisting of General Jark, Colonel Maribaron, Naval Commander Bosgan, and Captains Gatenzone and Gedorian.

The Lighter and Softer tone of the show clashed horribly with the Darker and Edgier Kamen Rider BLACK, and fans did not approve. However, it's quite wrong to label it a Franchise Killer, as the series had pretty good ratings (it performed better than Kidou Keiji Jiban, the Metal Heroes series that aired during the same season, and actually scored a slightly higher series average than Blacknote ). It's also notable as the first Kamen Rider series to introduce the concept of form changes, which became a staple of the Heisei era. Black RX still remains popular amongst the older franchise, and like its predecessor, it enjoys massive popularity in the overseas market.


Oh, and this show also received an "adaptation" by Saban (the guys behind Power Rangers), called Masked Rider.

Kamen Rider BLACK RX provides examples of the following tropes:

  • Nonstandard Character Design: Bujin from episode 7, an extremely rare tokusatsu monster-of-the-week who actually has an exposed human face.
  • Noble Demon: Zig-zagged with Bosgan; he refused to let Grand Zairus help him in his duel with RX...but he did have Chaps laying in wait.
  • Put on a Bus: Kasumi no Joe after some extensive injuries. He comes back after a while.
  • Refrain from Assuming: The ending theme, "Dareka ga Kimi wo Aishiteru" (Someone Out There Loves You), is sometimes known as "Lonely Heart".
  • Retcon: Kotaro brings Rideron to life by using the magic sea cave that brought him to life (never mind how the heck he got it down there). Except it wasn't the sea cave in Black, it was the elixir that Whale Mutant gave him. The cave was just Whale Mutant's home.
  • Rubber-Forehead Aliens: For some reason, some Crisisians have fleshy antlers for ears, while others don't.
  • Same Character, but Different: Kotaro is a lot spacier and more happy-go-lucky since last time we saw him. It helps that the Sahara family doesn't induce the same guilt or tension Kotaro had during the last battle with Nobuhiko/Shadow Moon (with Kyoko being his sister, and Katsumi being his girlfriend), and they really took good care of Kotaro, allowing him to show more of his more cheerful/joking side that he occasionally showed to Kyoko and Katsumi.
  • Superpower Lottery: The upgrades Roborider and Biorider
    • Really, Black RX as a whole has this. The Kingstone Flash alone is capable of ridiculous feats.
  • Taking You with Me: Maribaron attempts to do this in the final episode when she was deadly wounded by Crisis. She failed.
  • Technicolor Death: All over the place, but special mention goes to General Jark, who shoots lighting and fire everywhere, explodes into a cloud of flames, and then the cloud of flames explodes.
  • Theme Naming: A variation, though not by name. Each Crisis general summons monsters based on certain themes. Maribaron uses supernatural monsters, Gatenzone uses mecha monsters, Gedorian uses alien monsters, for example.
  • There Is No Kill Like Overkill: Variation. RX was the first Rider to use both feet for his Rider Kick. Every Rider before him only used one foot in their kicks - including Kotaro himself in his previous suit.
  • Thrown Out the Airlock: The Crisis Empire tries to dispose of Kotaro in this fashion. Fortunately, they didn't realize that the previous villains didn't call him Black Sun for nothing and this merely exposes him directly to the sun, evolving him into Kamen Rider Black RX.
  • Transformation Is a Free Action: Subverted; Kotaro is shown a few times to be able to change forms and back in less than a second, so presumably all the posing and speeches is just for show.
  • Weapon of Choice: RX has a different weapon for each form.


How well does it match the trope?
