Kazuya Oki

Kazuya Oki (沖 一也 Oki Kazuya) 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 Kamen Raidā Sūpā Wan, Masked Rider Super-1), the titular character from the Kamen Rider Series installment Kamen Rider Super-1.

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.

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.

Super-1, alongside the other Ten veteran Kamen Riders, fought against 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 in the United States, 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 fought against each other. Group 1: Rider 1, Rider 2, V3, Riderman and X; and Group 2: Amazon, Stronger, Skyrider, Super-1 and ZX. During the training, V3 and Riderman often could be seen fighting together. After Crisis made a public announcement regarding its invasion of Japan, the 10 Riders finally left to 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 Gran Zairus is about to finish him off, the 10 Riders finally arrive, rescuing RX and quickly escaping. Super-1 and the others introduce themselves to Kohtaro Minami, Black RX. Bosgun finds them, and proposes a duel against Black RX, however, Kohtaro's friend, Kyoko Matoba, V3, Skyrider and Super-1 soon notice Chaps hiding around the area to prepare an ambush, finishing them off. Following Rider 1's words, Kohtaro decides to face Bosgun in a fair match while the other Riders watch, and finishes him off. Meanwhile, Gran Zairus easily rips through the Japanese defense forces and brings down the city with his unmatched power. Kohtaro leaves to fight him again, and, after some hesitation, Stronger 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 1000ºC, and easily knocks out Super-1 and the other Riders. In the end, Black RX takes the battle and manages to destroy Gran Zairus, forcing it to self-destruct, but seemingly explodes with it.

Afterwards, Super-1 and the other Riders helped evacuate the city's population and started to plan defensive measures for the next battles. However, soon the 10 Riders saw themselves facing Spirit World Demons, resurrected Crisis warriors. V3 faced the Harmful Imp and Ant Runt alongside Rider 1, successfully counter attacking, and later defeated Erigitron by himself, but they soon recovered from their attacks with no damage. When the battle seemed hopeless, Colonel Maribaron, the one behind this attack, revealed that the monsters wouldn't die as long as she kept a set of golden feathers with her, but Black RX returned, alive, stealing the feathers, stopping and destroying the monsters by himself.

After Black RX returned, the 10 Riders decided to spread themselves to observe and take on the Crisis forces, while Black RX protected his friends. Like usual, V3 and Riderman left together.

Wanting revenge against Black RX, a powered up General Jark, commander of the Crisis forces, Jark Midler, kills Sunkichi and Utako Sahara, who had helped Kohtaro in the past, while taking their children as hostages. However, Kamen Rider Amazon saves the children and is quickly followed by V3, Riderman and X. V3 orders Amazon and X to take the children to Kohtaro, while V3 himself and Riderman face Jark Midler. However, there's an overwhelming difference in power between them, and V3 can't even damage him. Some time later, V3 and Riderman are launched through the air, falling downtown, near a combat zone where Kohtaro was helping. In a fair duel, Black RX ends up victorious over Jark, destroying him while the other Riders watch in amazement.

The Emperor Crisis calls Kohtaro for a personal meeting. However, Super-1 and the others decide to follow him 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 troops, 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 managed to survive the attack and meet RX after the battle was over. Following Rider 1's words, they all decide to part ways and fight evil around the world.

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.

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.
