Daisuke Yamamoto

"Go outside. Kids play outside under the sun. I, Amazon. Here to be your guide!!"

- his introduction to Victor.

Amazon (アマゾン), whose real name is Daisuke Yamamoto (山本 大介), is Kamen Rider Amazon (仮面ライダーアマゾン), the primary protagonist and eponymous character of the late 1974 Kamen Rider Series, Kamen Rider Amazon.

Personality
Amazon is a kind and forgiving man who tried his best to learn more about Japanese culture. Although he is very into friendship and tries to protect his friends with his full might, he was initially rather feral towards strangers that weren't children, and has more than once caused trouble because of it. This actually made him homesick for a time. He later on learns to become more civil towards others as he understands more about Japanese culture and language.

As mentioned before, Amazon is a forgiving man who even forgave and rescued Mogura who previously kidnapped Masahiko and tried to kill Amazon. Despite being forgiving, he will be angered towards others who hurt his loved ones, as full shown when he brutally defeated the Mushroom Beastman when it killed Mogura. He also seems rather intelligent, as he not only learned Japanese language and culture rather quickly, but also learned how to ride a bike in a short amount of time despite his previous fear towards it.

TV Series
He was an infant around the time of the plane he and his family were on crashed in the Amazon rainforest, leaving young Daisuke the sole survivor and grew up as a wild child, living off the land under the name of "Amazon" (アマゾン). However, Daisuke's idyllic existence is cut short when the Ten-Faced Demon Gorgos, massacres the village in search of the powerful "GiGi Armlet", which gives the bearer fantastic power. Elder Bago, last of the Incas, gives the GiGi Armlet to Daisuke for safekeeping while using his knowledge of Incan science and magic to perform a mystical "operation" on Daisuke, transforming him into the powerful Kamen Rider Amazon before he died.

Under Bago's instructions, Daisuke evades Gorgos and searches for Professor Kōsaka, who knew the nature of the Gigi Armlet. Meeting Kōsaka's nephew Masahiko Okamura, who obliges to teach him to speak and the ways of the world, Daisuke is infuriated at Kōsaka being murdered by the Kumo Beastman and drives him off to save Masahiko and his sister Ritsuko Okamura, who blamed him at first for her uncle's death until he made an antidote to the poison her friend Masako got from the Beastman Vampire Koumori. Though in the first half of the series, because he was isolated from any Japanese people as a child, Daisuke could not speak coherent Japanese and say only a few words. But through Masahiko helping him cope with the culture shock, Daisuke learned to speak properly.

While catching fish, Daisuke finds himself at a motocross, frighted by the culture shock before he saves a man named Tōbei Tachibana who was attacked by Kamakiri Beastman. Paying him back, Tōbei helps Daisuke overcome his fear of motorcycles to save Masahiko from the Akajuusha before Kamakiri attacks them, with Amazon killing the Beastman. But unnerved about why he is hunted by the Geddon, Masahiko learns of Yamamura, one of the members of Kōsaka's exploration party into the Amazon. Hoping to find the answer, they and Tōbei learn that Yamamura's on the run from Geddon as he holds the secret that Geddon would go to lengths to make silent. When Beastman Omukade captures Yamamura and his daughter, Daisuke pursues with newly built Jungler, saving them before killing Omukade. During the fight, Yamamura is fatally wounded by the Akajusha as Yanamura reveals the "GaGa Armlet", the counterpart of the GiGi, that Gorgos possesses before he died.

During the Mogura Beastman incident, Daisuke is arrested by the police for attacking an officer when they needed to know his identity in spite of his part in helping them get murderer Oshima. Though bailed by Tōbei, a confused Daisuke runs off with a hatred for humans. The next day, Tōbei and Ritsuko find Daisuke as he intends to return to the Amazon. Learning that Masahiko was abducted by Mogura and at Ritsuko's pleas, Daisuke saves his friend and give Mogura a severe beating. Daisuke later finds Mogura being punished for failing Gorgos, saving the Beastman who is shocked. Later, after being told by that Johoku University has gained relics from the Amazon that might shed some light, Daisuke and friends investigate and find the mysterious Quipu which Daisuke could decipher. But the Beastman Yamaarashi arrives and steals the Keep with Daisuke falling into his trap. But with Mogura's aid, Daisuke learns the story behind the GiGi and GaGa Armlets before killing Yamarashi, now knowing Geddon's goals.

While searching for Geddon, Daisuke receives a radio from Masahiko so he can know when Geddon's up to no good. After saving a woman from Kani Beastman, Daisuke learns that Mogura is forced by the monster of reveal Ritsuko as a potential weakness. Though he attempts to protect Ritsuko, Daisuke is saddened as she tells him that he's the one Geddon's after and it might be best for everyone if he just goes back where he came from. In spite of this, Amazon saves Ritsuko and friend from Kani and later receives a vest from Ritsuko as her way of thanking him. Eventually, Amazon faces off against Gorgos himself, destroying once he rips the GaGa Armlet off of him. However, the GaGa Armlet then falls into the hands of the Garanda Empire, led by the ruthless Great Emperor Zero. Amazon continues his fight against evil, eventually toppling the Garanda Empire and retrieving both bracelets. With his mission complete, he returns to the Amazon forest where he lived because it is his true home, though Tōbei believes that he will come back if evil comes to terrorize Japan again.

Stronger
One year after the destruction of Geddon and Garanda Empire, he returns (while for some reason no longer possessing the GaGa Armlet) from South America to backup Kamen Rider X who is in middle of a fight against Armored Knight. After Armored Knight loses one of his swords when X-Rider threw his Ridol Stick and he managed to escape, they shake hands together before helping Stronger defeat both Armored Knight and Commander Jishaku. He and X-Rider later rescue both V3 and Riderman and they soon meet Stronger again, who had been joined by Rider 1 and Rider 2 in their absence. The seven Riders, which would be known as the Seven Legendary Riders, marched against the Delza Army, who had captured Tōbei Tachibana. Finally, Stronger finishes off Marshal Machine. They meet Tachibana, but soon a new voice welcomes them, The Delza Army's Great Leader.

The Great Leader reveals that he had been behind the Delza Army, Geddon and other previous evil organizations opposed by the Riders. He takes on the form of a rock giant, impervious to the attacks of the Riders. However, they combine their powers and go into his body. There, they find a giant alien brain who self-destructs in an attempt to kill all seven Riders, however, they all escape successfully and leave, reminiscing everything they've gone through so far.

Skyrider
The evil organization Neo-Shocker moved ahead with its plans of global genocide. Daisuke Yamamoto, Kamen Rider Amazon, alongside the other Seven Legendary Riders fought around the world against it, leaving Japan's protection to the new Kamen Rider, Skyrider.

Super-1
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.

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.

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 Amazon, 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. Amazon 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 Amazon 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 Amazon 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, Amazon 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 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. Amazon 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
"Diend, friend."

- Amazon thanks Diend for returning the GiGi Armlet.

In Kamen Rider Decade: All Riders vs. Dai-Shocker, Amazon competes against Decade in the tournament to decide the strongest Rider. His biting maneuver is countered by Decade using the powers of Hibiki and retaliating with a burst of flame. At some point offscreen between losing to Decade in the tournament and arriving for the final battle, he had his Gigi Armlet stolen by Diend and yet still somehow survived. He joins all the Riders in the final battle against Dai-Shocker, after which Diend returns his Gigi Armlet.

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 Amazon, 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, Amazon 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.

However, they're all taken by a trap and Amazon is sealed in a Core Medal.

Later, Kamen Rider Fourze finds the seven sealed Riders, and with Kamen Rider OOO's help, releases all of them at once. V3 warns them that Kannagi will receive a full charge of cosmic energy if he reaches space, which would make him invincible according to Riderman, and he needs to be stopped now. Meanwhile copies of the Greeeds and Sonozaki Family Dopants approach the group, standing in their way. The Seven Riders stay behind facing them, while Fourze and OOO head to stop Lem Kannagi. Amazon fights against a copy Smilodon Dopant and finished it off with his Dai Setsudan. Meanwhile, OOO and Fourze managed to stop Lem Kannagi in space. Afterwards, in a scene added to the movie's Director's Cut, the young Riders, and also another Rider from the future, Aqua, said goodbye to each other and to the veterans, everyone parting ways afterwards.

Fourze Hyper Battle DVD
At some point during the Kamen Rider Fourze series, Amazon witnessed an object fall from the sky and land in the rain-forest. Investigating, he discovered that the object was an Astroswitch and recognized it as belonging to Kamen Rider Fourze. Amazon starts off for Japan in order to give Gentaro the Switch (and because he had taken a liking to the young man during the events of Mega Max), sending word to the Kamen Rider Club of his arrival. Gentaro and Yuuki Jojima prepare by learning an Incan greeting dance from Tomoko Nozama and give Kengo Utahoshi a brief history lesson about Amazon. However, when he fails to show up at the designated time, Gentaro worries that he's been blown off, while Kengo says one of the Legendary Seven Riders would never do such a thing, and suggests that Amazon may be in trouble.

When the trio goes to investigate, they're confronted by Suddendath Beta, a new version of the Foundation X Mutamit from Mega Max who claims to have defeated Amazon to prevent Fourze from gaining his new Switch. While Gentaro keeps Suddendath Beta busy, Kengo and Yuuki venture to South America to find Amazon, spending twelve days wandering aimlessly and being terrified by the local wildlife. However, on the twelfth day, when Yuuki says "Your friends are looking for you!", Amazon leaps out of the leaves nearby and heads off to Japan. There, he helps fight Suddendath Beta and gives Gentaro the Clear Drill Switch, which enables him to defeat the Mutamit. After the battle, Gentaro does his greeting dance for Amazon, who likes it and joins in.

After meeting, Gentaro and Amazon exchange their gestures of friendship (Amazon's hand sign or Gentaro's handshake), but because the DVD has minor choose-your-own-adventure elements, which gesture is used is determined by the viewer.

Kamen Rider: Battride War Genesis
Amazon is among the Showa Riders who make their Battride War debut in this game. Amazon's unique trait is his Condorer belt and its variety of functions; he can use the Condorer Rope to perform a swing kick or to reel in enemies, and it can act as a mortar and pestle that lets Amazon craft healing items during battle. His special attacks include the Monkey Attack, Spin Kick, Amazon Kick, Jaguar Shock and Daisetsudan, with his Super Finishing Move is the Super Daisetsudan, powered by the combined GiGi and GaGa Armlets as his final attachment for his final form state, which empowers his claw dashing special into a projectile. Amazon is an agiled aerial fighter who has more air special moves than any other Riders.

Fighting skills
Amazon fights in a berserk and wild way such as biting and scratching. He also moves very swiftly like a gymnast and fights while ignoring wounds inflicted to him by his opponents. Presumably his best area of advantage is the Amazon rainforest where he grew up in and other forest related places. Even without transforming, Amazon can lift a bike with his bare arms showing that he possesses great strength (like most of his predecessors).

Transformation
With the GiGi Armlet on his person, Amazon transforms into his Rider form with the cry 'A-MA-ZON!' while pulling his arms inwards and clenching his hands in claws then stretching out and opening his hands.
