 is the main protagonist of Kamen Rider Den-O. He is a Singularity Point who journeys across the timeline as alongside the Taros onboard the DenLiner.
He was temporarily possessed by the Ghost Imagin and forced to become .
==Imagin Possessions==
Due to his special status as Den-O, he can resist the control of an Imagin contracted to him, among other things, as long as he's conscious. As Ryotaro continues on his journey, he meets more Imagin, each taking his body and using it as their own for the duration of their possession. Each of his personality changes affect the color of his eyes and some strands of his hair, changing its color to match the Imagin while gaining their abilities and some of their strength along with it.
*When possessed by Momotaros, Momo is in Ryo's body. His hair spikes up slightly with a single red streak and he gains more muscular definition and the physical strength to go with it.
* When possessed by Urataros, Ura is in Ryo's body with the right words to woo women and convince almost anybody. His hair is straight and calm and has a single blue streak going through it. He also wears a pair of black rimmed eyeglasses(although in one episode of Kamen Rider Decade, he is seen wearing a white suit, a blue tie, and a matching top hat with a blue band in addition to his usual appearance.)
*When possessed by Kintaros, Kin is in Ryo's body. His hair grows such that he has a ponytail with a golden yellow streak through it. However, his increased strength often results in self-injury and clumsiness.
*When possessed by Ryutaros, Ryu is in Ryo's body, incorporating dancing into everything he does. He grows one long purple and black streak of hair and is always seen wearing a brown cap. His reckless personality infests itself upon Ryotaro, and usually causes him to destroy whatever is around if he gets out of control. One such incident occurred during the events of Climax Deka when R-Ryotaro arrested everyone who he thought looked suspicious and was part of the "Evil Organization" advertised by Negataros.
*When possessed by Sieg, though they never forged a contract, Sieg is in Ryo's body. His hair is styled in cornrows and has several white highlights with one longer white and black lock on the left side of his face, and a white feather boa appears around his neck.
*While Yuto was removed from time, Ryotaro gained a contract with Deneb, Deneb is in Ryo's body. His hair grows out past shoulder length with two locks of hair on each side of his head. On the right side, the lock is a neon green with a darker green streak within it.
*When abducted by Shiro and possessed by the Ghost Imagin in the events of Final Countdown, Ryotaro's personality is overwritten by the evil Imagin's will. His hair turns snow white as it grows out long and spiky with light-yellow cat's eyes.

==History==
=== Early Life ===
====Childhood====
Born on December 26, 1988 as the son of Shinichi and Kayoko Nogami, Ryotaro and his sister Airi became orphans at a young age, their parents dying in an untold accident. Living with their grandmother, Ryotaro and Airi regularly made visits to the closed down Milk Dipper as children, it being among the few mementos of Shinichi and Kayoko. Originally, the two also possessed a picture of their parents as well, but Ryotaro's carelessness led to its disappearance, with Ryotaro feeling regretful ever since. 
At the age of ten, a juvenile Ryotaro becomes involved with his future self's battle against Kamen Rider Gaoh, tagging alongside the Den-Liner crew as "Kotaro".  Replacing the amnesic Ryotaro, Momotaros temporarily possesses "Kotaro" instead, transforming into Kamen Rider Mini Den-O.
After the battle, "Kotaro" and his older counterpart are rewarded with the chance to see their late parents in the past, allowing both Ryotaros to remember Shinichi and Kayoko's faces. Once returning to his own time, the younger Ryotaro draws a picture of his parents, with the current Ryotaro retaining it in the present. 
====Young Adult====
Ryotaro and Airi eventually re-opened the Milk Dipper with the aid of his sister's fiancé. However, when Airi's fiancé mysteriously disappeared a month before the wedding, Airi suffered from amnesia, losing all memories of her fiancé. Worried for her, Ryotaro dropped out of high school just before graduation, deciding to financially assist Airi instead. 
===Becoming Kamen Rider Den-O ===
When he finds the Rider Pass, Ryotaro unwittingly becomes the protector of time and space known as Kamen Rider Den-O, fighting the Imagin who traveled to the year 2007 to grant wishes and travel further into the past to change the future to their liking. As he is a Singularity Point, he is immune to the effects of changes to the past, and he can also resist the temptations of an Imagin, as seen with the hotheaded Imagin he named Momotaros, whose contract provides Den-O with a fighting form. He is assisted by the Singularity Point Hana as well as the crew of the DenLiner, a train that allows him to traverse time in pursuit of Imagin. They are the mysterious Owner of the DenLiner and the dining car's waitress Naomi. Along the way, he becomes contracted to other Imagin who give him the ability to access three of Den-O's other forms. They are the lying Casanova Urataros, the herculean and narcoleptic Kintaros, and the childish yet strong Ryutaros.
Ryotaro later identifies a mysterious man who has been following him through the past as his sister's fiancé Yuto Sakurai, but then meets a young man who calls himself Yuto Sakurai and his Imagin contract Deneb, the team that can become Kamen Rider Zeronos. Upon meeting Yuto, he begins to learn more about the nature of time and the Imagin, and is told by Yuto that protecting people is not as important as protecting time. Ryotaro does not believe this and feels that the two are one in the same, and he will do so, despite his own weaknesses.
Ryotaro also briefly meets the Swan Imagin Sieg who allows him to access another form, and later the evil Kamen Rider Gaoh who hijacks the DenLiner to travel to the past to obtain the the Gaoh-Liner, leaving Ryotaro without memory of being Den-O for a while, meeting his past self as a result, until Gaoh takes him to the Tokyo of December 26, 1988, the day Ryotaro Nogami was born, in an attempt to erase him. To defeat him, Yuto travels in time to pick up three other incarnations of Ryotaro for Urataros, Kintaros, and Ryutaros to possess and aid Ryotaro in the "Climax Scene", destroying the GaohLiner and defeating Gaoh. In the process, while getting to see his parents firsthand, Ryotaro learns how "people's memories are time".
Upon his return to the present, Ryotaro learns that because he retains only the memories of fighting Gaoh as Sword Form while his past selves are incapacitated, he has no memory of fighting as Rod, Ax, or Gun Forms. This causes Urataros, Kintaros, and Ryutaros to all dissolve into sand, from which Ryotaro's feelings manifest the K-Taros. This restores the three lost Imagin, and gives Ryotaro access to the stronger Den-O Climax Form.
When Ryotaro's actions cause the Junction Point to manifest, his sync with the Tarōs starts to dissolve as a side effect, forcing him to fight as Plat Form. However, solving the crisis in advance, the Tarōs use their powers to create the DenKamen Sword so Ryotaro can assume the powerful Den-O Liner Form so he can fight on his own. Shortly thereafter, he meets the Singularity Point Kai, who seeks to make the Imagin's future the true future, by seeking to destroy the Junction Point, who is later found to be Ryotaro's sister Airi. As a result, Ryotaro falls into a trap set up by Kai to keep him from Airi, with Kintaros and Urataros sacrificing themselves so Ryotaro can return to the present. In the process, Ryotaro learns that his missing memory is tied to the true identity of the one who will ensure that the flow of time and space leads to the future without Imagin: his niece who is revealed to be Hana/Kohana.
After the final battle is over, Ryotaro is saddened by the supposed loss of the Tarōs, only to find out that they and Sieg, still existing due to their memories together, are hiding in a ditch attempting to surprise him. Ryotaro is overjoyed that they are all still alive and celebrates happily. With his mission to protect time from Kai and his Imagin finished, Ryotaro relinquishes his Rider Pass back to the Owner of the DenLiner, thanking everyone for what they have done for him. As he rides his bike back to the Milk Dipper, he is greeted by all of the riders of both the ZeroLiner and the DenLiner who bid him a final farewell before departing into the time stream. Ryotaro smiles as they pass by, knowing that he will meet them again someday in the future.
Later, when an Imagin named Negataros steals the Rider Pass from Owner, Ryotaro joins the newly formed DenLiner Police to stop Negataros and his "Evil Organization", succeeding thanks to the aid of Kamen Rider Kiva. After the case was closed, Ryotaro and the DenLiner crew keep the DenLiner Police going just for kicks.
However, Ryotaro is forced to resume being Den-O when he is possessed by the Ghost Imagin for Shiro, using the Signality Point in order to travel into the past while having the possessed Ryotaro as his enforcer, Kamen Rider Yuuki Skull Form. But through Momotaros' aid, Ryotaro manages to regain control so he can let his Imagin partner in his body to purge the Ghost Imagin before they finish the Imagin off in Climax Form. But during the climatic final battle against the revived Imagin, Ryotaro, Momotaros, and Kotaro assume their rider forms to defeat Shiro when he becomes Yuuki Hijack Form.
After formally meeting his grandson, Ryotaro promises him he won't divulge any learned knowledge of the future as he takes Kotaro and Teddy home on the DenLiner.
== Other Events ==
===Kamen Rider Decade ===
====Here Comes Super Momotaros!====
With Ryotaro off investigating an error in the timeline, there is no one person with the Tarōs that has the power of Den-O and the Tarōs manage without a permanent body to use. Following the departure of Ryotaro, (prior to Tsukasa and company entering Den-O's World,) the Tarōs suddenly lost the ability to maintain their physical forms due to the actions of an unknown force that is altering their present at some time in the past. The alteration of the present also ended up de-aging Ryotaro a few years, making him a young boy/teenager as a result.
Seeing the Mole Imagin surfacing to be connected to it, Momotaros possesses Tsukasa to fight one. After being evicted from Tsukasa's body by Natsumi's pressure point, Momotaros attempts to re-possess Tsukasa, but ends up in the body of Yusuke instead. After Tsukasa manages to get Momotaros to talk back at the Hikari Photo Studio, M-Yusuke storms off to solve the mystery behind his world's crisis.
As he is trying to figure out why buildings are disappearing, M-Yusuke is confronted by Daiki who wishes to know where the DenLiner is, revealing a DenLiner Final FormRide Card in his possession that would supposedly allow Momotaros to regain his physical form. Momotaros refuses, and then begins a fight with Diend as Den-O Sword Form, escalating against him with Diend using Sasword and Saga to outnumber him before he is sent plummeting off of a building. He survives as Diend takes his leave for Momotaros to reconsider.
Elsewhere, as Tsukasa and Natsumi investigate Den-O's World by finding the DenLiner and use it to go back to the time it started, Urataros, Kintaros, and Ryutaros each possess Tsukasa, revealing that they were warned of Decade and believe he is connected to the disturbances in their world. When Tsukasa manages to force them all out, they take over Natsumi's body, each using her to fight Decade in their respective Den-O Form as Decade counters as Agito. During the fight, both Riders are transported to another dimension similar to where the Rider War took place in Natsumi's dream. The fight would ultimately end in a stalemate as the DenLiner picks them up. Upon entering, they are greeted by Naomi, Kohana, and Owner, who would talk to them about teaming up to solve the mystery.
After tending to his injuries from taking out another Mole Imagin, M-Yusuke is confronted by Tsukasa before he senses the Imagin he's looking for, the Alligator Imagin. Chasing him to the past, Den-O is nearly killed by the Alligator Imagin when Decade and Diend intervene, with Diend using his Riotrooper card to hold the Imagin at bay. Diend would once again offer Momotaros a true body of his own, but Decade somewhat defends Momotaros, regaining his access to Den-O's powers.
Through the modified Final Form Ride Card, Momotaros regains his physical form and, after a slight misunderstanding from Yusuke, takes out the Alligator Imagin by using Kuuga Gouram as part of his Finishing Attack. Although the crisis is over another occurs after Momotaros returns to the DenLiner, with the Tarōs disappearing and Momotaros ending up on Onigashima as part of the Oni Conquest legend.

====Kamen Rider Heisei Generations Forever====
During the events of the film, the main villain Tid forcibly turned Ataru into Another Den-O to use as a pawn for his grand scheme. Tid, Another Den-O, and their grunts proved too formidable for Fuutaros, Kamen Rider Zi-O and Kamen Rider Geiz to defeat on their own, all three heroes being swiftly overwhelmed. Just when it seemed all hope was lost though, mysterious flashes of light suddenly transported everyone (barring Tid) within the vicinity. Finding themselves at a station, Sougo and his friends were saved by the real Den-O. Each Taros took turns as Den-O to attack their fake counterpart, with Urataros as Den-O Rod Form being the one to finish Another Den-O.
Both transformations were canceled, and a man possessed by Urataros reaches out to Ataru. It was Ryotaro himself, now in his late twenties. Introducing himself as "Kamen Rider Den-O, time officer of love and justice", Urataros in Ryotaro's body encourages Ataru that one exists so long as they are remembered by others. Ataru nods in agreement, with Sougo stating that he will not forget his predecessor. Glad to hear this, Ryotaro and Urataros wish them luck before they transport back to Tid's location. Once Sougo's group had left the station, Momotaros, Kintaros, and Ryutaros then reappear alongside Owner, discussing their identity as Den-O and overall existence as individuals. Despite their usual banter, in a rare moment of solemnity, Momotaros tells Ryotaro that they would always continue to remember him as their friend. While Ryotaro remained silent, his eyes flashed back to their usual color, with a slight smile being given in response.

==Personality ==
Ryotaro is a very shy and timid man, with a tendency for misfortunes. However, when seeing another person in trouble, Ryotaro never hesitates to help them, doing so to his best ability. Faithful to honesty and perseverance, Ryotaro greatly dislikes acts of injustice and self-sacrifice, seeing it as unacceptable.
Genuinely believing that people can change, Ryotaro is willing to place his trust towards anyone who requests it, gaining the Taros' friendship and loyalty. From the many battles fought with his allies, Ryotaro significantly boldened in nature, though retaining his gentle mannerisms. 
When reverted back into a child, Ryotaro's impulsiveness increased substantially, acting more recklessly in dangerous situations. 
As a running gag, Ryotaro has a very poor sense of style in general, to the chagrin of the Taros and his grandson. This extends to his powers as Den-O as well, to the point of constantly shouting Liner Form's finisher attack as "Train Slash" (Densha Giri) without embarrassment.
==Powers and Abilities==
===Powers===
*Singularity Point: As a Singularity Point, Ryotaro is immune to time paradoxes, though still susceptible to the Gaoh-Liner, Zeronos cardsNo Possession, No Secession, Train Slash!, and Zi-O's powers. 
**Temporal Protection: Even after a timeline paradox, Ryotaro's mind and physical appearance retains its original state. This makes him invaluable against time manipulators, as most other primary Riders do not possess this ability.
===Abilities===
*Combatant: Lacking power in general. Ryotaro often relies on Momotaros and other Imagin to fight in his stead. As he trained more though, Ryotaro became a capable fighter in his own right, using Liner Form without any help.
*Indomitable Will: Singularity Points possess the ability to withstand the temptation of free wishes that the Imagin offers and can expel them when conscious. However, certain Imagin such as Ryutaros can bypass this immunity entirely, unless Ryotaro musters enough willpower to stop them.
==Forms==
The Den-O Belt works by drawing in energy from the surrounding area, allowing it to generate the Den-O suit, which consists of a soft but durable material called and tough armor called . As the name implies, Aura Skin and Armor are attuned to the wearer's individual aura, being created from their sense of self. 
Since Ryotaro's weak will prevents him from bypassing Plat Form, he relies on the Taros for support, each providing him access to one of Den-O's four basic forms. 
By swiping a Rider Pass across the SetTouch and/or through possession by an Imagin, Kamen Rider Den-O is able to pass through multiple forms that matches the Imagin's will, creating a unique Aura Skin and Armor that matches the Imagin's will, as well as generating a facemask called a .
The four basic forms are based on a specific mythological hero along with motifs relating to the respective legends. 
==Equipment==
===Devices===
*Den-O Belt: Transformation belt
*Rider Pass: A device to scan on the belt
*K-Taros: Transformation device to become Climax, Liner, or Super Climax Form
===Weapons===
*DenGasher: Personal weapon
*DenKamen Sword: Liner Form's primary weapon
*ZeroGasher: Temporarily borrowed from Kamen Rider Zeronos 
===Vehicles===
*DenLiner: Den-O's personal train
*Machine DenBird: Den-O's Rider Machine
==Legend Rider Devices==
==Relationships==
===Family===
*Airi Nogami: Being his older sister, Airi is very close to Ryotaro, acting as a parental substitute. Ryotaro likewise cares deeply for Airi's well-being, wishing for her to one day regain her memory of Yuto Sakurai.
*Hana/Kohana: Ryotaro's future niece. Having no knowledge of their relation to one another, Hana and Ryotaro regarded each other as good friends, with Hana constantly looking out for Ryotaro's well-being.
*Yuto Sakurai (Past Man): As Ryotaro's future brother-in-law, Yuto taught him the importance of perseverance, encouraging Ryotaro to not despair from his misfortunes. When Yuto mysteriously disappeared, Ryotaro was significantly saddened, wishing for Yuto to return home one day.
*Kotaro Nogami/Kamen Rider NEW Den-O: Ryotaro's future grandson. Annoyed that Ryotaro gave him the name "Kotaro", Kotaro initially held little respect towards his grandfather, perceiving Ryotaro as a weak person. Ultimately though, Kotaro gains a newfound sense of respect for Ryotaro, accepting his given name without issue. In the future, an elderly Ryotaro is to have retained a cordial relationship with his grandson, arriving to pick up Kotaro and Teddy after their battle against Shiro.
===Friends & Allies===
*DenLiner Crew
**Taros
***Momotaros/Den-O Sword Form: His first Imagin contract. Initially disliked Momotaros because of his immature justice. But after Momotaros is able to understand how important Ryotaro is for him, he becomes Ryotaro's most dependable Taros.
***Urataros/Den-O Rod Form: His second Imagin contract and the first to become one without Ryotaro's permission. Despite Urataros' womanizing and lying attitude, Ryotaro knows that Urataros is actually not a very bad person and becoming the first person that Urataros never betrayed.
***Kintaros/Den-O Ax Form: His third Imagin contract. Initially met as enemy until Ryotaro realized that Kintaros is not a bad Imagin as he only wanted to help people to become stronger. Ryotaro saved his life before dying and Kintaros also becomes the most wise looked Imagin for Ryotaro. Kintaros even went far to make Ryotaro accidentally pact a contract with the Taros to fight with him forever in their climax moment to face on Kai.
***Ryutaros/Den-O Gun Form: His true second Imagin contract but becomes the fourth because of his late action. Ryutaros is considered as a little brother for Ryotaro because of how childish Ryutaros is. He is not even scared of Ryutaros despite his true purpose is to kill him which he later discards.
**Hana: Hana becomes Ryotaro's most depended partner to solve the case of Imagin. She is also a mentor like for Ryotaro.
** Naomi: Naomi is considered as a friend for Ryotaro.

** Sieg/Den-O Wing Form: The second Imagin who is not his contract but sometimes aids him in battle. Ryotaro is one of some people who never avoid him despite how much of a nuisance Sieg is.
**Teddy: Kotaro's Imagin
*Seigi Ozaki: Seigi has no true close relationship and is always laughing at Ryotaro's bad luck gift. There are times that he will help Ryotaro to gather some information for catching Imagin without his own realization of the purpose so Seigi can become closer to Airi.
* Issey Miura: Issey has no true close relationship at first, until he discovered that Ryotaro is possessed by Taros who he thought of as evil spirits at times.
==Behind the Scenes==
===Portrayal===
Ryotaro Nogami is portrayed by Takeru Satoh, who made his final consecutive portrayal of the character in Saraba Kamen Rider Den-O: Final Countdown. As Satoh began to rise in popularity within the Japanese entertainment media, Toei was no longer able to afford hiring him for reprisals, resulting in the character being re-written in a way to accommodate for Satoh's absence from the role. Going forward, the character was de-aged and portrayed by Takuya Mizoguchi, until Takeru's surprise return to the role in Kamen Rider Heisei Generations Forever.
In the video games Kamen Rider: Climax Heroes and Battride War, he was voiced by veteran voice actor Yuta Kasuya.
===Rider No.===
As the leading Rider protagonist of Kamen Rider Den-O, Ryotaro Nogami (Kamen Rider Den-O) is labeled and . 
==Notes==
*Partly due to Takeru Satoh's increasing unavailability from appearing in future Kamen Rider productions by his agency, Den-O has since then been primarily represented by Momotaros, barring a period when Ryotaro was de-aged and portrayed by actor Takuya Mizoguchi. Thus, many assumed that Ryotaro gave up his role as a Kamen Rider altogether; something disproven in Heisei Generations FOREVER. 
*When de-aged into a child, Ryotaro's physique as Den-O remains unchanged. This is from retaining his mind and spirit as an adult.https://www.kamen-rider-official.com/zukan/character/767
