Hiroshi Tsukuba

Hiroshi Tsukuba (筑波 洋 Tsukuba Hiroshi) is Skyrider (スカイライダー Sukairaidā), the main protagonist of the 1979 Kamen Rider Series installment Kamen Rider, more commonly referred to as Skyrider or The New Kamen Rider and very rarely as Kamen Rider #8.

History
Hiroshi is a young man who hang glides for fun and studied karate under Ryoichi Miyoshi. Three years prior, he lost his parents and sister in a car crash. While on a picnic with his friends, Tsukuba witnessed Professor Keitarō Shido being pursued while hang gliding and saves him from a gang of Ari Commandos. Soon after, Tsukuba finds his friends have been all murdered for his meddling before being approached by Midori Kanō, who takes him to Shido as the man informs Tsukuba of the terrorist organization Neo-Shocker.

While finding Imata Tonda snooping around Shido's safe house, Tsukuba finds the scientist abducted by Gameleojin, the monster who murdered his friends. But when the pursuit resulted with Tsukuba critically wounded, Shido convinces General Monster, who realized the young man's potential, to allow him to convert Hiroshi into a cyborg. Coming to, Hiroshi wanders out of the NeoShocker complex and learns of his new nature before he accidentally transforms into SkyRider. Using his new found ability, SkyRider destroys Gameleojin and embraced his new-found existence as a means to stop Neo-Shocker's evil. To keep a low profile in his search for Neo-Shocker's base, Tsukuba founded the Shido Hang Glide Club with Shido.

Eventually, after Neo-Shocker Plus-Alpha Bomb on Tokyo, Shido takes his leave without warning to join the Anti-Neo-Shocker Commitee overseas. However, Shido arranged for Tsukuba to be supported by his old friend Genjiro Tani, who happened to be a mentor to Tsukuba in the past. For the first 19 episodes of New Kamen Rider the hero is known as "Kamen Rider", but in episode 20 Kamen Rider Stronger addresses him as "Skyrider". All of the previous Kamen Riders call him Skyrider and the Neo-Shocker kaijin do so as well after episode 20. Towards the end of the series comic relief is provided by the bumbling, superhero-wannabe, GanGan G. In episode 48, Skyrider has to fight 3 fake Skyriders (Dororingo). As usual the evil Riders wear yellow scarves. Later on, Hiroshi meets his parents who turned out to be alive and held hostage by Neo-Shocker only to sadly part with them for good. This served as a huge maturity point for him. In the finale, the Riders fought the Great Boss of Neo-Shocker. The Leader and Neo-Shocker itself is destroyed at the hands of Skyrider and the Original 7 Riders.

Kazuya Oki, Kamen Rider Super-1, fought against the Dogma Kingdom to stop them from awakening an ancient weapon. However, in his way stood the Dogma Revenge Corps, troops of rebuilt cyborgs from Dogma Kingdom and Neo-Shocker. When he seemed overwhelmed by his enemies, Rider 1 suddenly reappeared, followed by the other 8 previous Riders, all alive. V3 tells Super-1 to let that battle in their hands, and soon they fight against Dogma's troops to open way for Super-1. V3 briefly faces Dogma Fighters, Gyosutoma & ArigiThunder. Fighting alongside Riderman, V3 finishes off Zombieda with a throw while his partner does the same to Ganigannii. V3, Riderman and X go on to use a triple Revolving Kick to finish off, respectively, Kamagirigan, Snakecobran and ArigiThunder. Thanks to the help of the Riders, Super-1 reaches Dogma's troops on time and stops them. After the battle, the Riders show themselves to Super-1 and his friends, and promise to fight for humanity's future together.

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.

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 fail 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.

Skyrider, 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. Skyrider 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 Skyrider 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, Skyrider 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, Skyrider 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. Skyrider 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 the worlds, Tsukasa Kadoya (Kamen Rider Decade) announced a tournament gathering all Riders to find who was the strongest. Skyrider participated in the tournament fought against Kamen Rider Ixa, though he did not make it to the final where Decade emerged victorious. Skyrider and the other defeated Riders disappeared into a dimensional wall and were taken for dead, leading Dai-Shocker to initiate its offensive.

Eventually, Decade turned against Dai-Shocker and faced its troops alone. However, a large dimensional wall appeared in the battlefield, and from it, all Riders thought to be dead reappeared. Skyrider marched on foot with the other Riders as 1, 2, and V3 rode in on their motorcycles. United, all the Riders proceeded to face off against Dai-Shocker's army. When Shadow Moon was thrown onto the Dai-Shocker Castle, Skyrider participated in the All Rider Kick, using his standard kick alongside the other Riders to destroy Shadow Moon and the Dai-Shocker castle.

Soon after, Dai-Shocker's final weapon, King Dark, emerged from the ruins of the Dai-Shocker Castle and attacked. Decade was transformed into Final Form Ride Jumbo Decadriver and merged with Kamen Rider J summoned by Diend to face it. To help Decade, Skyrider, alongside the other Riders, turned into giant Kamen Ride Cards to power up the giant Decade's Final Dimension Kick, destroying King Dark. After the battle was over, Skyrider and the other past Riders bid goodbye to Decade and his friends before leaving through a dimensional wall.

Tsukaba, along with Tendou (Kamen Rider Kabuto), formed an alliance with Kazuya Oki (Super-1) 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 is assumed that Hiroshi along with the other riders were restored in the alternate world and its riders were also restored.

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 Skyrider, 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, Skyrider 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.

Due to the timeline alteration caused by Shocker, Skyrider became one of the brainwashed Riders in that timeline. 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. After the alternate timeline was restored, Skyrider rode away to parts unknown.

Personality
A kind person with a fascination for the sky, Tsukuba was constantly helping others in both Rider and human forms. While he lost his family at an early age, he managed to live life and tried to enjoy every little bit of it. Even after being altered into a cyborg, Tsukuba decided to help others with his new powers by fighting Neo-Shocker. While at times troubled by the situation, he was helped by others around him like his predecessors. Later on Tsukuba shows his parenting side when he took care of Bongo when he was a baby while humorously being called "mama" by him. While Tsukuba stated that he would kill Bongo when he grew up, in the end when Bongo died after he showed how much Tsukuba meant to him, Tsukuba cried tears of sadness. After learning that his parents were still alive, Tsukuba somewhat showed an obsession with finding them which sadly ended tragically. While he was saddened when his parents were killed, he still did his best and stopped Neo-Shocker along with his predecessors for the innocents showing how much he's matured as a person.
