Hayato Ichimonji

Hayato Ichimonji (一文字 隼人) is Kamen Rider 2 (仮面ライダー２号), or Kamen Rider 2-go, a character from the Japanese Tokusatsu Television series Kamen Rider, the first in the famous Kamen Rider franchise of tokusatsu programs. The secondary Protagonist of the series, like Kamen Rider 1, is a motorcycle-riding superhero modeled upon a grasshopper.

Personality
Ichimonji is an optimistic man who tries to make people happy and cheerful even in the darkest moments despite his own misfortunes. Although he originally resented his cybernetic enhancements, he has nonetheless learned to live with it as he fights evil around the world. It was hinted that the reason Ichimonji is a photographer is because he wanted to capture the smiles of people.

Originally, Ichimonji was rather naive, hot headed, and simple in contrast to the more sharp and calm personality Hongo had. It was after sometime did Ichimonji learn to think more with his head and matured to the point where he became a mentor to Kazami alongside Hongo. Although he matured more, Ichimonji doesn't seem to have lost his kindness and good nature as shown in later episodes and sequels.

It was hinted in one of the Climax Hero games that Ichimonji is a strict teacher compared to Hongo throughout dialogue between him (Ichimonji) and Kazami.

Biography
Born October 10, 1949, Hayato Ichimonji is a free-lance photographer, kidnapped by the organization Shocker in order to become a reconstructed human able to fight the deserter Takeshi Hongo, aka Kamen Rider. Before Shocker scientists had a chance to brainwash him, Hongo appears and saves Ichimonji's sanity. Hongo leaves Japan to fight Shocker branches overseas, and Ichimonji becomes his successor as Kamen Rider, protecting Japan from Shocker's actions.

Some time later, Takeshi Hongo returns to Japan and fights alongside Ichimonji. Now, Hongo is known as Kamen Rider 1 and Ichimonji, Kamen Rider 2. The pair is occasionally called "The Double Riders". With Hongo back, it's Ichimonji who now leaves Japan for training in South America. Near the end of the series, Rider 2 is back to help Rider 1 to defeat Gel-Shocker, Shocker's new denomination.

V3
The Double Riders next appeared in the sequel Kamen Rider. The titular V3 was Shiro Kazami, a junior of Hongo's, and begged them to turn him into a Kamen Rider after the murder of his family by the Destron organization. Despite initially refusing, when the young man was mortally wounded assisting them, the two Riders transformed him into Kamen Rider V3, possessing both Kamen Rider 1's "skill" and Rider 2's "strength". After fighting and being unable to stop Bazooka Turtle (presumably due to giving Kazami a portion of their power which temporarily weakened them) they decided to stop Bazooka turtle by unleashing their full power to stun him and grabbed him while jumping at a great height to detonate the atomic bomb. The Double Riders were initially thought to be killed by said bomb, but reappeared alive and well later on in the series.

X
G.O.D.'s forces attack various points of Tokyo, meanwhile, to fight against his threat, the previous four Riders return from various points of the globe, with Rider 2 returning from Paris. The five Riders, following one of the Franken Bat's bat spies head to one of G.O.D's bases. After fighting through G.O.D.'s revived monsters, the five Riders face Franken Bat. The four Riders helped X execute the "Rider Super High Kick" technique, destroying Franken Bat. They invaded a G.O.D. base and faced King Dark, but the entire complex was merely an illusion, which disappeared while King Dark laughed at them.

When Tachibana Tobei was captured by Leech Dracula, he appeared and saved Tobei. While X remained to face Leech Dracula, Rider 2 and V3 went ahead to stop King Dark at once, however, Kind Dark easily sealed the path to him, avoiding facing them.

X would later be defeated and captured by the villain monster Tiger Nero, who wanted the plans for the RS Mechanism, which G.O.D. would use to create a powerful weapon, in exchange for his rescue. Tobei Tachibana gave the plans, only to be captured too, but he had also called Shiro Kazami, who transformed into V3 and saved them. However, they were unable to recover the plans. In a later encounter, when Tiger Nero attempted to use the newly built weapon against them, however, it turns out that one of G.O.D.'s scientists was actually Ichimonji Hayato, who sabotaged the experiment. The three Riders fighting together stopped Nero, only to be challenged by King Dark.

Rider 2, V3 and X all went their own ways looking for G.O.D.'s main base, but neither Rider 2 nor V3 found it on time, leaving the final battle to X by himself.

Stronger
After the destruction of the previous evil organizations, he returns with 1, coming back from India to rescue Stronger who was hanging on a waterfall from Marshal Machine, Commander Jishaku, and Armored Knight who trying to lure and trap X and Amazon. Later he fights as well as nearly loses against Marshal Machine while Kamen Rider 1 fights against Armored Knight and Kamen Rider Stronger fights against Commander Jishaku. After Commander Jishaku and Armored Knight were defeated and captured by 1 and Stronger, he points a gun against Commander Jishaku and Armored Knight and tries to negotiate with Marshal Machine by telling him if he wants his two subordinates alive, he must release both Kamen Rider V3 and Riderman. However, Marshal Machine tells them that if his two subordinates are not released, he will order his troops to kill both V3 and Riderman. Just when it seemed like there was no choice but to free both his two subordinates until Kamen Rider X and Kamen Rider Amazon appeared to tell them that is no longer needed since they freed both V3 and Riderman as they regroup with the others again. The seven riders, which would be known as the Seven Legendary Riders, marched against the Delza Army, who had captured Tachibana Tobei. Finally, Stronger finishes off Marshal Machine. They meet Tachibana, but soon a familiar voice welcomes them, Delza Army's Great Leader.

The Great Leader reveals that he had been behind the Delza Army, Gel-Shocker 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 about everything they've gone through so far.

Skyrider
The evil organization Neo-Shocker moved ahead with its plans of global genocide. Ichimonji Hayato, Kamen Rider 2, alongside the other Seven Legendary Riders fought around the world against it, leaving Japan's protecting to the new Kamen Rider, Hiroshi Tsukuba, Skyrider.

Eventually, Neo-Shocker gathers a Second Generation Cyborg Corps in Japan, led by Gurand Bazarmy, known as the Strongest Cyborg on Earth, and also plans to launch a direct offensive with an experimental tank, the Varithium Cannon, led by Hirubiran. To save Japan, the seven Riders return and, alongside Skyrider, destroy the experimental Varithium Cannon and Hirubiran. However, they are soon challenged by Gurand Bazarmy and his troops.

Neo-Shocker troops start kidnapping many people around Japan in order to work as slaves in their operation to bring about a large volcanic eruption in Japan. The seven Riders spread around Japan to fight against various attacks from Neo-Shocker. In a later battle, Skyrider is easily wounded and left unconscious while trying to face Gurand Bazarmy. While he recovers, the Riders communicate telepathically with the unconscious Hiroshi Tsukuba. The Riders tell Skyrider that he should go through an intense training where he'd receive their powers, multiplying his strength 20 times to fight against Gurand Bazarmy again.

After Skyrider's training is finished, all Riders leave to face Neo-Shocker again. Skyrider faces Gurand Bazarmy, while the Legendary Seven fight against Neo-Shocker's Second Generation Cyborgs troops. Gurand Bazarmy and his army quickly fall before the Riders. After the battle is over, the Seven Riders leave Japan again, to fight Neo-Shocker all over the world, while Skyrider remains to protect Japan.

Neo-Shocker makes an alliance with an alien, the self proclaimed Galaxy King, and starts an operation to explode Mount Fuji. When Skyrider is ambushed by another troop of second generation Second Generation Cyborgs led by Jaguar Van, all seven Riders arrive to face their forces and allow Skyrider to proceed. After the battle, all 8 Riders leave to fight Neo-Shocker elsewhere.

Having located Neo-Shocker's main base, Hayato and Shigeru summoned their fellow Riders from across the world, uniting the Seven Legendary Riders. They head to Neo-Shocker's underwater base, only to be faced with a giant dragon, Neo-Shocker's, Great Leader himself. Rider 2's and everyone else's attacks prove to be ineffective against the Great Leader, however, they hold on long enough for Skyrider to arrive. Skyrider stuns the Great Leader by shooting his foot with a bowgun, and, using the opportunity, all Seven Legendary Riders hit him with their Rider Kicks, knocking down the giant. However, he was still alive, and decides to explode alongside a giant bomb, taking out not only himself, but Earth itself by destroying it`s atmosphere. The eight Riders combine their powers and use Skyrider's Sailing Jump together, grabbing the Great Leader and taking him to the distant sky, where they all explode, all eight Riders seemingly perishing alongside it when in truth they were blasted across space until they regrouped in Super-1.

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 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.

Black RX
Kamen Rider 2, 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. Rider 2 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 Rider 2 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 Rider 2 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, Rider 2 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 Rider 2, 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. 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.

Shadowmoon is thrown onto Dai-Shocker's castle, he participates in the All Riders Kick, using his standard Rider Kick alongside the other Riders to destroy Shadowmoon and the Shocker castle. Afterwards, Dai-Shocker's final weapon, King Dark, appeared from the rubles of the castle, and Decade merged with the Kamen Rider J summoned by Diend to face it. To help Decade, Rider 2, alongside the other Riders, turned into giant Kamen Ride cards to power up the giant Decade's final attack, destroying King Dark.

Shin Kamen Rider Spirits
The first volume of the revived Kamen Rider Spirits Manga gives readers a more detailed origin story of Hayato and how he became Kamen Rider 2.

After witnessing Kamen Rider 1's battle with Bat Man from afar while on a rooftop, Hayato began investigating Kamen Rider and Shocker's activities. He then observed Takeshi Hongo from a distance and took photographs of him from 800 meters away, which Takeshi detects thanks to his super hearing. He then was followed by Takeshi on his motorbike and the young photojournalist said he simply wants the truth and has learned about Shocker. Hongo was silent about the issue and after leaping over an oncoming truck, told Hayato to stay away from Shocker if he valued his life. Hayato introduced himself to Hongo and told him he would still pursue the truth regardless.

Hayato interviews victims and relatives of Shocker victims, who try to convince Hayato of their story and give details on Shocker. As he gets angry about all the pain the organization has caused, he then gets a call from Ruriko Midorikawa who wishes to speak with him. He learns her father's murderer was not who she thought it was and wants Hayato to drop the investigation. Hayato asks her if she knows the Kamen Rider and correctly deduces that he is Takeshi Hongo, which causes her to slap him after his teasing and prodding.

The manga then showcases an alternate version of Episode 13, with Hayato witnessing Takeshi become Kamen Rider while observing the FBI trying to investigate Shocker. While Kamen Rider is pre-occupied with the Revived Kaijin army, the agents on the stakeout are ambushed by more of the Kaijin. Most of them are killed, but Hayato rushes in to save the last two, beating down the Kaijin with his bare hands. Dr. Shinigami observes these events and decides Hayato would be the perfect candidate for "The Next" project. Shinigami then orders the monsters to capture Hayato, who despite his injuries manages to fend them off long enough for the other FBI agents to escape.

When the agents bring a blueprint of a Shocker base in Yumesima Landfill to Ruriko, Kamen Rider investigates with Kazuya Taki and finds Hayato converted into a cyborg. He saves him, but Hayato is unable to control his super strength. Hayato at first doesn't accept what he is, but then comes to the aid of Kamen Rider when Shocker sends the Shocker Riders to destroy him, christening himself as Kamen Rider 2. While looking around the base, Ruriko finds a fleet of motorcycles and steals one for Hayato to ride. After a long and brutal fight, Hayato destroys the last Shocker Rider with his first true Rider Punch. Hayato then collapses from his injuries and Takeshi repairs his body, lamenting that maybe he should not have saved him as now he has led another down the hellish path he walks. Takeshi thinks that his humanity made him desire a friend to quell his loneliness, and as if a twisted answer to his desire, another individual has become like him. However, Hayato accepts what he is and wants to fight alongside him. The volume ends by stating that despite Takeshi's lament, nine heroes now walk the same path as Takeshi.

Kamen Rider: Battride War Genesis
Rider #2 is among the Showa Riders who make their Battride War debut in this game.

Althought Rider 2 is thought to be an easy character to pick, but he has a hidden R1 function like W FangJoker and his separate left-half Kamen Rider Joker. His hidden R1 function is a Quick Cancel, giving Rider 2 cancelling the attack and making him the most powerful Rider to do an infinite combo.

Fighting skills
Even at the start of his appearance Ichimonji was already a six degree judo black belt and a five degree in karate showcasing his skills. After becoming Kamen Rider 2, Ichimonji became strong enough to defeat Shocker cyborgs that even Hongo initially couldn't defeat on his own showing how much of a gap there was between them. After Hongo trained and became physically stronger it seemed Hongo has surpassed Ichimonji. Ichimonji does still show a lot of skill though, and can still keep up with Hongo in a tag battle. While Hongo fights until he finds the monster's weakness and finishes them off accordingly, Ichmonji would fight his opponents man to man and resorts to improving and improvising his arsenal of finishers to suit the monster and  the situation.

Even though Hongo is the more famed one in terms of skill, one shouldn't underestimate Ichimonji for just his strength.

Helmet
Kamen Rider 2 originally appeared with a dark green/silver helmet, when his costume was updated as Kamen Rider New 2, he had a silver helmet as with Kamen Rider New 1. In Rider 2's return in the movie V3, he had a dark green helmet, possibly because of how similiar his design is to Rider 1's final suit. However, in the tv show, Rider 2 reappeared with the light helmet The same happened in X's tv show and movie, with Rider 2 having a dark helmet in Five Riders vs. King Dark, but a light one for his tv appearance. Finally, in Stronger, Rider 2 reappeared with an even darker, basically black helmet, which kept being used for all of his appearances up until the Kamen Rider ZX TV special. He returned to the light helmet during Kamen Rider Black RX and his first two Heisei crossover appearances, Kamen Rider Decade: All Riders vs. Dai-Shocker and Let's Go Kamen Riders, but in Movie War Mega Max, the black helmet returned and was also used in Kamen Rider × Super Sentai: Super Hero Taisen. The helmet returned to its light color in  and Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai. The black helmet is also used in Kamen Rider Spirits and Kamen Rider SD.
