Kazuya Oki

"No... I can't die just yet... because I have yet to see how humans grasp their future!"

- Kazuya to Captain Serge

Kazuya Oki (沖 一也) is a member of the International Space Development Program who becomes the cyborg Kamen Rider Super-1 (仮面ライダースーパー１), the titular character from the Kamen Rider Series installment Kamen Rider Super-1.

Personality
An easy to get along sort of guy, Kazuya is hard working and just. Along with some of his predecessors and successors, Kazuya initially fought for revenge rather than justice, but like most of them he learned to fight for what's right. Although some of his actions are questionable, (a great example being that he volunteered to have surgery to change his body into a full cyborg, whereas most of his predecessors were initially horrified at no longer being normal) he is still a pretty good guy that went as far as to stop Jin Dogma despite the odds. When he appeared in Decade however, Kazuya acted rather differently as he referred to Tsukasa as the devil and tried to kill him without hesitation. Perhaps the reason for that was that he was an alternate Super-1 instead of the original. Ether way, Kazuya (like most of the other main riders) turned back to normal in his later appearances.

History
Kazuya volunteers to undergo cybernetic surgery in the International Space Development Program in the United States in order to become an Astronaut who can survive in outer space without the need for a bulky external suit. After a successful operation, he is given the codename "Super-1". Before he can depart for space, however, the base where he received his operation is attacked by the Dogma Kingdom. Only Kazuya is able to escape.

Determined to avenge the deaths of the scientists, he returns to Japan and is trained by a martial arts expert, Master Genkai. With this knowledge, he is able to transform into the powerful Kamen Rider Super-1.

At the half of the series, Super-1 finally topples the Dogma Kingdom, only to encounter another evil group called the Jin Dogma. At this point, the series became much more lighthearted, with the introduction of the Junior Riders, who serve as comic relief, and the bizarre Jin Dogma kaijin. Jin Dogma's monsters are based on household objects, such as Ladders, Basketballs, and Refrigerators; reminiscent of Obake from Japanese folklore.

He later on meets his predecessors who were all alive and well.

Ultimately, Kazuya defeats Jin Dogma, allowing Japan to exist in peace. He then finally fulfills his childhood dream and ventures into outer space with the help of a new team of scientists.

ZX
The Badan Empire, led by Ambassador Darkness, spread its claws around the world, and, to face it, the nine Riders came together. When Badan initiated its Space Break System, a destructive dimensional weapon, all 9 Riders gathered in Japan to stop them. Shiro Kazami coordinated an operation to stop Badan from getting Badanium 84, fuel for its weapon. With each Rider targeting a different transport, V3 stopped Dokuga-Roid from carrying the Badanium 84 and destroyed his truck, but Dokuga-Roid himself escaped while V3 faced his Combat-Roids.

Meanwhile, Super-1 and Riderman saw themselves facing a warrior called ZX, who had been fighting against Badan too. V3 arrived and stopped ZX, telling him that they're all enemies of Badan and want to destroy the Space Break System. Along with Riderman and Super-1, they explain to ZX, Ryo Murasame, the history and meaning of being a Kamen Rider, and, finally, he decides to join them, as the 10th Rider, Kamen Rider ZX.

Afterwards, Badan's base was located, and all 10 Riders went towards it. Ambassador Darkness welcomed them and sent all of Badan's troops against the Riders. V3 faced Dokuga-Roid and his Combat-Roids again, and after a long battle managed to destroy him by throwing him onto a fallen Yamaarashi-Roid. Afterwards, V3 and Rider 2 teamed up against Jūjin Ōmukade, a revived Geddon monster. however, before the battle could be finished, Ambassador Darkness attempted to use hostages to make the Riders surrender. His plan failed due to Super-1's interference and Ambassador Darkness decides to use the Space Break System, only to destroy Badan's remaining troops. After V3's call, the ten Riders gather their power with Rider Syncro, weakening Ambassador Darkness and allowing ZX to finish him off. After Darkness is defeated, evil energy gathers in the shape of a giant skull, The Generalissimo of Badan, giving farewell to the Riders and laughing at them.

V3 bestows upon ZX the official name Kamen Rider 10 and soon all Riders part ways again to continue their battle against evil around the world.

Black RX
Kamen Rider Super-1, alongside the other Nine veteran Riders, fought against the secret forces of the Crisis Empire spread throughout the world, defeating them in each country. However, Crisis' main forces, in Japan, still remained and they prepared a final offensive. Rider 1 called all Riders to a meeting in a secret facility in Arizona, to prepare for the upcoming battle, where they'd go to help Kamen Rider Black RX, the Kamen Rider that was defending Japan at the time. The 10 Riders split into two groups, which sparred with each other. Group 1: Riders 1, 2, V3, Riderman and X; and Group 2: Amazon, Stronger, Skyrider, Super-1 and ZX. Before Crisis makes a public announcement regarding its invasion of Japan, the 10 Riders finally leave for the final battle.

After Crisis' war declaration, they immediately sent Gran Zairus, which landed on Earth like a meteor, destroying an entire island. Naval Commander Bosgun moved to attack Black RX, soon receiving help from Gran Zairus, who could resist all of RX's attacks. When Bosgun is about to finish him off, Rider 1 arrives, blocking his attack and kicking him away. The 9 Riders arrive shortly afterwards, rescuing RX and quickly escaping. Super-1 and the others introduce themselves to Kohtaro Minami. Bosgun finds them, and meeting Kohtaro and Rider 1, proposes a duel against Black RX. However, Kohtaro's friend, Kyoko Matoba soon notices a Chap hiding behind some crates to prepare an ambush and flushes it out. As the 10 veterans fight them off, Black RX faces Bosgun in a fair match and destroys him.

Meanwhile, Gran Zairus easily rips through the Japanese defense forces and brings down the city with his unmatched power. Kohtaro decides to fight, but Riders 1 and 2 argue that even Black RX's attacks are ineffective against Gran Zairus and they need a strategy before facing it again. Kohtaro decides to fight anyway, even if he dies trying. He leaves to fight again, and Super-1 and the other Riders follow him.

The 11 Riders face Gran Zairus, but even a combined Rider Punch with the power of the 11 Riders is useless against him. Gran Zairus transforms into a flaming rock, burning above 1000°C, and easily knocks out Super-1 and the others. In the end, Black RX becomes Biorider and manages to destroy Gran Zairus from the inside out, but seemingly explodes with it.

Afterwards, Super-1 and the other Riders help evacuate the city's population and start to plan defensive measures for the next battle. However, a second Rider 1 appears during their meeting. The real Rider 1 accuses the impostor and punches it, making it reveal its true form, Harmful Nimp. The 10 Riders face Spirit World Demons, resurrected Crisis warriors. Unfortunately when the monsters knocked down, they quickly get up again. When the battle seems hopeless, Colonel Maribaron, the one behind this attack, reveals that the monsters don't die as long as she keeps a set of golden feathers with her, but Biorider returns, alive, stealing the feathers. Rider 1 receives one of the golden feathers, and V3 holds Harmful Nimp while he uses the feather to stop it. Biorider then destroys the monsters all by himself.

With Kohtaro alive, the 10 Riders decide to spread themselves to observe and take on the Crisis forces, while Black RX protects his friends.

Wanting revenge against Black RX, a powered up General Jark, commander of the Crisis forces, gains a new form called Jark Midler, kills Sunkichi and Utako Sahara and faces V3 and Riderman while X And Amazon bring their kids to Kohtaro. Meanwhile, Crisis' forces start a human hunt. Riders 1 and 2 arrive to help Kohtaro face the Chaps' troops. Stronger, Skyrider, Super-1 and ZX soon follow. X And Amazon show up with the kids and Inform Kotaro on what happened. V3 and Riderman are launched through the air, falling downtown, near the combat zone where Super-1, alongside the other Riders, were helping Kohtaro. Jark challenges Kohtaro to a duel, and he accepts, rejecting the help of the other Riders. Black RX ends up victorious over Jark, destroying him while the other Riders watch in amazement.

Emperor Crisis calls Kohtaro for a personal meeting. However, Rider 1 tells Amazon to follow them, and all the other Riders go too. The emperor offers Kohtaro the chance of becoming the commander of Crisis' invasion forces, however, after Kohtaro refuses, General Dasmader appears alongside a group of Chaps and attacks Kohtaro. Super-1 and the other Riders arrive and face the Chaps, but soon the entire cave is destroyed by the Crisis Fortress called by Dasmader. Black RX boards the fortress and destroys Dasmader, the Emperor and even Crisis itself. Meanwhile, the other Riders survive the attack and meet RX after the battle is over. Following Rider 1's words, they all decide to part ways and fight evil around the world.

All Riders vs. Dai-Shocker
To stop the fusion and destruction of worlds, Tsukasa Kadoya, announced a tournament gathering all Riders to learn who was the strongest. Super-1 participated in the tournament and made it to the finals, where he teamed up with Kamen Rider V3 and Kamen Rider Black while fight against Kamen Rider Decade, Diend and Kuuga(Onodera). Diend escapes, and, with his V3 Screw Kick, V3 knocked out Kuuga, leaving only Decade in combat. However, Decade still managed to defeat the three Riders "Triple Kick" with his own Dimension Kick. Afterwards, Super-1 and the others disappeared into a dimensional wall and were taken for dead, leading Dai-Shocker to initiate its offensive.

Decade: Final Chapter
Kazuya along with Tendou (Kamen Rider Kabuto) form a team with Tsukuba (Skyrider) to fight against Tsukasa (Kamen Rider Decade). But they failed and were defeated by Decade and sealed away in his cards. After Decade was defeated, it's assumed that Kazuya along with the other riders were restored in the alternate world and its Riders were also restored.

Let's Go Kamen Riders
A mishap caused by the Greeed Ankh unintentionally altered the timeline which enabled Shocker to utilize a Cell Medal to create the Shocker Greeed which defeated the Double Riders and seemingly erased the legacy of the Kamen Riders from history. In 2011, after Kamen Rider New Den-O's attempt to repair the damage, he along with Kamen Rider OOO and M-Ankh awaited execution. However, it was revealed the Double Riders had their brainwashing removed by a Shocker scientist.

The Double Riders joined with New Den-O and OOO to fight Shocker's forces, but were eventually defeated. When the order was given to kill everyone, V3 suddenly appeared, asserting that there were more than four riders. V3 was soon followed by all the other revived riders that came after him, including Super-1, as even though Rider history was changed, the people's memories haven't changed.

After the riders were united, they faced off against Shocker's Great Leader. Later, when joined by a force of extra riders, Super-1 and all the other riders got on their motorcycles and performed the "All Rider Break", ramming into the Rock Great Leader and defeating it once and for all.

Super Hero Taisen
Super-1 was among the Kamen Riders caught up in the 'Super Hero Taisen' incident. He was presumably sent to the dimensional rift, under the pretense of being defeated, by Captain Marvelous while he was apparently hunting the Riders. When his and Tsukasa's ruse was revealed, Super-1 and the other Riders appeared through the dimensional wall. Super-1 then fought alongside all the other Kamen Riders and Super Sentai against Dai-Shocker and Dai-Zangyack's Shocker-Zangyack Alliance. He was seen aiding TimeYellow against Arch Orphnoch, fighitng a gormin sailor, and with Den-O and DynaPink against a Dogoumin.

Super Hero Taisen Z
Super-1 is set to appear in Kamen Rider × Super Sentai × Space Sheriff: Super Hero Taisen Z. He joins with Kamen Riders Fourze, Meteor, Decade and Space Sheriff Gavan Type G, as well as the Super Sentai teams Choushinsei Flashman and Tokusou Sentai Dekaranger, as the three forces of super heroes confront Space Shocker. He performs the Space Rider Double Kick with Kamen Rider Meteor.

Kamen Rider Taisen
As one of the 15 Showa Riders, Super-1 fought in the battle against the 15 Heisei Riders in Zawame City.

Super-1 appeared with Amazon to fight both Kamen Rider Joker and Baron after they defeated RX turning Baron into Lockseed after defeating him. He later fights with his Elek Hands and was seen against Shouichi Tsugami (as Agito Ground Form and Trinity Form) in battle with both riders destroying each other through the collision of their attacks.

Super-1 was later released with all the other sealed Riders by Kamen Riders Gaim and ZX. United, all 30 Kamen Riders teamed-up to take down the revived Badan Empire.

After Badan was defeated, Super-1 fought with the Showa Riders in a final showdown against the Heisei Riders. Super-1 took on Ryuki, enduring his Dragon Rider Kick Final Vent. The battle was ended when Rider 1 and Gaim reconciled on the differences of the two sides of Kamen Riders.

Due to the timeline alteration caused by Shocker, Super-1 became one of the brainwashed Riders in that timeline, donning the name of Shocker Rider Super-1. Later on, he aided the other Riders to combat Shocker after he, and the other Riders, were released from being brainwashed by the revived Double Riders.

Fighting skill
Since the start of the series, Kazuya was already an Astronaut which shows how skilled he was in both mind and body. After getting cybernetic surgery and training under Master Genkai to become a user of the Sincere Shaolin Fist, Kazuya became Kamen Rider Super-1.

Kamen Rider Super-1
"Super-1!"

- Transformation announcement

Punching power: 300 ton

Kicking power: 500 ton

​The arsenal of Kamen Rider Super-1 was developed by the group known as the International Space Development Program. Super-1 was designed as a space cyborg which can survive the harshness of deep space exploration. Along with having enormous strength and skills, Super-1 can change his Five Hand gloves to use his super punches, shoot 10,000 volts of electricity, gain greater strength, shoot missiles to emit radar waves and use ice powers on his left hands while using his right as a flamethrower.

In Kamen Rider Spirits, it was shown that Kazuya's body as Super-1 was designed with high resistance to extreme temperatures. This was best showcased when he went outside of a free falling space shuttle re-entering Earth's atmosphere to try to correct its trajectory. Despite showing signs of burns and some minor damage to his cybernetics when the shuttle landed, Super-1 survived atmospheric re-entry temperatures of over 1,500° F.
