Kazuya Oki

Kamen Rider Super-1 (仮面ライダースーパー１, Kamen Raidā Sūpā Wan) is the titular character from the Kamen Rider Series installment Kamen Rider Super-1.

Kazuya Oki
Kazuya Oki (沖 一也, Oki 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.

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.

OOO, Den-O, All Riders: Let's Go Kamen Riders
A mishap caused by the Greeed Ankh unintentionally altered the timeline which enabled Shocker to utilize the Core 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.

Kamen Ride Super-1 (カメンライドスーパー1) is the Kamen Ride Card which contains the power of Super-1.

Kamen Rider Diend first used the card in the World of Decade, summoning Super-1 alongside Black RX and Agito to fight Doctor Shinigami and the Dai-Shocker Soldiers in the 7-Eleven promotional campaign.

In All Riders vs. Dai-Shocker, Decade Complete Form Jumbo Formation performed the Final Dimension Kick, a variation of the Dimension Kick, transforming the Shōwa Riders, including Super-1, and Heisei Riders into Kamen Ride cards for Decade to travel through as opposed to Final Attack Ride cards before hitting the target.

In theory, this card would allow Kamen Rider Decadeto transform into Super-1.

Trivia
Kamen Rider Super-1 has the most Rider Kick varations of a single rider (26) mostly due to his martial arts training.
