Kotaro Minami/Kamen Rider BLACK RX

Portrayed by: Tetsuo Kurata (live), Jiro Okamoto (suit actor)

https://static.tvtropes.org/pmwiki/pub/images/kohtaro_rx.jpg
The Child of the Sun
Our hero, now 20 years old and working as a helicopter pilot for the Sahara family. When the Crisis Empire invades Earth, they capture Kotaro to prevent Kamen Rider Black from posing a threat to them and throw him out into space, only for the sun's radiation to recreate Kotaro's broken Kingstone and grant him the power to transform into the stronger Kamen Rider BLACK RX.


To see his tropes applied to his appearance in Kamen Rider BLACK, click here.

Tropes apply to him in general:

  • The Ace: Kohtaro's abilities and skills as a Kamen Rider speak for itself. Likewise, he is a trained helicopter pilot, soccer player, and mechanical engineer.
  • Badass Biker: His return as Black RX also sees Battle Hopper being revived as Acrobatter, allowing him to become this again.
  • Badass Driver: In addition of having Acrobatter already, he rides the Ridoron, an insect-themed super car, making him the first rider to drive car.
  • Came Back Strong: The Crisis Empire threw him out into space in an attempt to kill him, but being closer to the sun just makes him come back as the more powerful Black RX.
  • Decomposite Character: Black RX is often made a separate character from Kamen Rider Black in Crossover events to justify the two Riders appearing side by side. Whether the other Kotaro is the from an Alternate Universe, Time Travel or by some other means isn't always clear.
  • The Determinator: Never gives up his fight against the Crisis Empire. Whenever he's a particularly tight pinch he just wills himself another form to get out of it.
  • The Hero: Carrying on the role as the sole person fighting the Crisis Empire's invasion.
  • Iconic Outfit: His default outfit is a white jacket with the words "F. Grand Prix" written on its back.
  • Iconic Sequel Character: A carry-over from the previous series. He's already the protagonist, but considering he's the only lead Kamen Rider to get to star in his own sequel series he definitely qualifies by Kamen Rider standards. To this day, he's nearly as popular as Takeshi Hongo himself.
  • In the Name of the Moon: "I am the child of the sun! Kamen Rider! Black! RX!"
  • Lightning Bruiser: To be expected, considering his accumulated prowess from the previous series, alongside the Kingstone's mystical properties. It's honestly no surprise that he can take on an entire alien armada.
  • No Kill Like Over Kill: In a sense. Not that he can be blamed for it, but Kohtaro's victory over the Crisis Emperor cause the Crisis Empire's subjects to all die. For reference, the population was over 5 BILLION in total.
  • Old Hero, New Pals: Kotaro's new allies consist of a family who runs an airline company, his girlfriend, a chef, a Cyborg Sidekick, a psychic archer, and later, the original ten Kamen Riders.
  • Story-Breaker Power: Kohtaro's Kingstone is so powerful that it basically grants him any power needed to solve the plot (human possession, immunity to time paradoxes, and cheating death itself).
  • So Last Season: Maribaron implied that if Kohtaro remained as simply Kamen Rider Black, then he'd be much easier to defeat. That said, since Shadow Moon still proved formidable as ever in his reappearance, this was likely a statement born from ignorance.
  • Strong as They Need to Be: Not that the Kamen Rider franchise isn't guilty of this from the start, but still. You'd think that with all his accumulated prowess and experience, as well as being upgraded into Black RX, Kohtaro could easily decimate an average Kaijin in seconds. Yet, he tends to struggle against them from time to time, with his Rider Kick rarely dealing the finishing blow.
    • Heck, in the time-travel special, past Kohtaro/Black defeated a typical Crisis Empire monster without any difficulty. Remember, Black RX is several times stronger in comparison.
  • The Power of the Sun: The sun was responsible for giving him his new form as Kamen Rider Black RX, and can act as an alternate energy source if the Kingstone is damaged.
  • This Is Unforgivable!: His reaction to Jark's killing of Shunkichi and Utako.

Tropes exclusive to Kamen Rider BLACK RX:

https://static.tvtropes.org/pmwiki/pub/images/krbrx_blackrx.png
  • Finishing Move:
    • RX Kick: An upgraded dropkick version of Black's Rider Kick. Though it normally doesn't outright finish off his opponents, it is powerful enough to stun and weaken them so he could deal the deathblow with his Revolcane.
    • Revolcrash: Black RX draws out his Revolcane to stab his opponents, unleashing a torrent of energy until they are fatally wounded. Kinda makes you feel sorry for them.
  • Fragile Speedster: As Biorider, RX is super fast at the cost of losing defense. However, this is almost never an issue, due to having the ability to become intangible as Gel-Form, with Shadow Moon being the only one in the series to bypass this.
  • Jack of All Stats: His base Black RX form. He doesn't have the Super-Strength of Roborider or the Super-Speed of Biorider, but he's still super strong and agile enough to surpass Black. Heck, when pushed, said form even DEFEATED an enhanced Shadow Moon, the latter previously outdoing Roborider and Biorider in their respective strengths.
  • Laser Blade: The Revolcane.
  • Mighty Glacier: Roborider grants RX intense durability and strength at the cost of moving super slow, barring his shooting reflexes.
  • Swiss-Army Hero: Can switch between his base form, Roborider form and Biorider form.
  • Worf Effect: Like the rest of the Showa Riders, he is heavily subjected to this in sequels. To note, he was once swiftly defeated by Decade in a Rider tournament, while Shadow Moon (A.R.) easily trounced the latter later on.
    Ten Legendary Kamen Riders 

Ten Legendary Kamen Riders

The ten Kamen Riders which came before RX: Kamen Riders 1, 2, V3, Riderman, X, Amazon, Stronger, Skyrider, Super-1 and ZX. They show up late into the series to help Kotaro in his fight against the Crisis Empire.
  • Big Damn Heroes: Show up to rescue Kotaro after he's been felled by a particularly strong Monster of the Week.
  • Worf Effect: They pretty much have no meaningful presence in the story after their introduction, other than to make Black RX appear stronger in comparison. Heck, even with their combined powers, all ten were outmatched by Strongest Monster Gran Zairus. Not to mention V3 and Riderman's very one-sided fight against General Jark.

    Joe the Haze

Crisis Empire

An Evil Empire from space seeking to invade Earth. Coming from a world wrecked by pollution and other factors, they seek to turn Earth into their new home planet.
    General Tropes 
  • Contrasting Sequel Antagonist: Unlike Gorgom, who are a group of mutants, cultists, and terrorists that seeked a new boss and to rule Earth, the Crisis Empire are supernatural invaders who sought to Take Over the World due to their homeworld dying and believing that humanity has no regard for the Earth and kept on polluting it.
  • Create Your Own Hero: They inadvertently caused Kotaro's transformation into Black RX by capturing him from Earth before he escapes from their fortress in space, exposing him to more radiation in the sun and giving him an upgraded form.
  • The Empire: They were supposedly once a peaceful society, but a change in leadership led to them becoming aggressively expansionist.
  • Mecha-Mooks: The Chaps, robotic soldiers who serve as the Crisis Empire's main Mook force.
  • Monster of the Week: The "Strange Demon Soldiers", a diverse array of monsters under the Crisis Empire's belt whom they send out Once an Episode.
  • Mook Lieutenant: Each of the four officers under General Jark heads a different Monster of the Week division.
  • No Kill Like Over Kill: To be expected from their desire to exterminate humanity. Fittingly, they are all indirectly slaughtered by Black RX in the end.
  • Standard Evil Empire Hierarchy:
    • The Emperor: Emperor Crisis.
    • The Right Hand / Security Officer: Inspector Colonel Dasmader.
    • The General: General Jark, commander-in-chief of the Crisis military, and underneath him the commanders of the Crisis Empire's three army divisions, Armored Captain Gatezone, Naval Commander Bosgun and Fanged Captain Gedorian.
    • The Guard: General Jark again, as commander of the Crisis Fortress.
    • The Oddball: Intelligence Staff Officer Maribaron.
    Emperor Crisis 

Emperor Crisis

Portrayed by: Gorō Naya

The ruler of the Crisis Empire.
  • Ambiguous Situation: Whether or not he's another incarnation of the Great Leader. He's played by Gorō Naya, whose voice was usually the Great Leader's calling card, but besides that there's no confirmation in series if the two are one and the same, or even if Crisis is in any way related to him.
  • As Long as There Is Evil: Though Black RX fells him in the end, Crisis claims that he and his empire will be reborn as long as humanity's evil continues to exist.
  • Big Bad: The ruler of the Crisis Empire and the one behind their invasion of Earth.
  • The Emperor: of the Crisis Empire.
  • Load-Bearing Boss: The Crisis Empire's home world disappears after Grand Lord Crisis is destroyed.
  • Lord Country: His name is Lord Crisis and he's the ruler of the Crisis Empire.
  • No One Sees the Boss: He's The Ghost until the final few episodes, where he finally decides to get directly involved in the invasion.
  • Tyrant Takes the Helm: The Demon World was apparently peaceful until he rose to power and turned it into an industrialized, expansionist society.
  • We Can Rule Together: Attempted this on Kotaro in the finale. Unsurprisingly, Kotaro shot it down.
    General Jark 

General Jark/Jark Midler

Portrayed by: Seizō Katō (voice, 1-44), Hidekatsu Shibata (voice, 45-46), Toshimichi Takahashi (suit actor)

  • Bling of War: Wears bright golden armor.
  • The Dragon: He's the Emperor's Number Two and military commander.
  • Eye Scream: His left eye got busted by Black RX (as Biorider) during their final duel.
  • The Heavy: Since Crisis himself rarely appears, it's Jark who spearheads the invasion of Earth and carries the plot each episode.
  • Killed Off for Real: Is finally killed by Black RX after a long and hard fought battle between the two.
  • One-Winged Angel: After his repeated failures to defeat RX, he gets mutated into Jark Midler by Crisis and sent out in a final mission to kill RX.
    Maribaron 

Intelligence Staff Officer Maribaron

  • Hypocrite: Bosgun outright tells Gran Zairus that he'll kill Black RX by himself and yet he has some Chaps on standby.
  • Made of Iron: A mild example, but he is the only villain who takes two stabs from the Revolcane to die.
  • The Starscream: Once plotted to usurp Jark.
  • Theme Naming: His Crisis Kaijin have the prefix "Gyna" in their names.
