Ryutaros

is an Imagin member of the Taros who transforms into 's Gun Form.
==History==
Promised by Kai that he would become the DenLiner's conductor if he kills the Singularity Point, Ryutaros enters Ryotaro's body prior to his contact with Urataros. He is eventually revealed when Issey Miura places Ryotaro under hypnosis, able to force the other Taros out of Ryotaro as he takes the human's body for a spin. Later emerging from Ryotaro's body when attracted by Naomi's coffee inside the DenLiner, revealing his intent to kill Ryotaro, Ryutaros is revealed to have a Rider Ticket Kai gave him that allows the Imagin to remain on the train. However, having developed feelings for Airi Nogami, Ryutaros decides to not go through with it. Because he knows that Airi has loved Yuto Sakurai, Ryutaros was jealous and took faulty advice on love from Kintaros to nearly kill Yuto in a fight before Ryotaro took control. Though he forgave him for previous moments, Ryotaro gives Ryutaros a severe warning not act on his own again. Ryutaros is also credited with being the one who allowed Sieg to come upon the DenLiner, even allowing him access to a luxurious train car.
During the events of Kamen Rider Den-O: I'm Born!, Ryutaros possesses the Ryotaro that Yuto brought for the Climax Scene. This has a negative side effect which caused Ryutaros to fade from existence were it not for Ryotaro's feelings condensing his remains into the K-Taros, restoring him to normal while allowing Ryutaros to form the chest armor of Den-O's Climax Form until his synch with Ryotaro was negated. However, Ryutaros drew up the concept design of the DenKamen Sword, his power now accessed in the Ryu-Gun Mode.
Eventually, Ryutaros meets up with Kai,who tricks him into sabotaging the ZeroLiner without knowing the consequences of the DenLiner being taken and rendered powerless. Due to the event, Ryutaros matures and takes the new timeline's effects hard, being forced to realize that he couldn't be with Airi as she recognized him not to be her Ryotaro. After Ryotaro stands up to Kai for him, Ryutaros, like the other imagin, learns repect towards Ryotaro and is now more willing to help Ryotaro out in any way he can. Ryutaros can perform his own variation of Gun Form's finisher, Wild Shot, although it is simply a powered shot due to the lack of additional charges.
As the new year approaches, Ryutaros is saddened and confused over both Kintaros's and Urataros's decision to abandon the DenLiner and remain in the past to fend off the Imagin army. During the final battle, he catches Ryotaro as he falls from a building at the last second, and is the first to fight the Death Imagin as Den-O Gun Form, and lent his power for the finishing blow against the Death Imagin. During the events of Climax Deka, as a member of the DenLiner Police, Ryutaros causes an incident while searching for the "Evil Organization", arresting anyone who merely looked suspicious. He finally gets his closure with Airi when they meet face to face and he bashfully accepts the meal she made. During the events of "Final Countdown", Ryutaros assumes Gun Form (on his own) during the epic battle against the revived Imagin, determined to protect the time from being destroyed, having seen an Airi doppelganger in the time where they were, who also turns out to be an ancestor of Ryotaro and Kotaro.

====Super Den-O Beginning====
Ryutaros appears when He, Kintaros, and Ryutaros possess Tsukasa and chase after Natsumi for answers. When Tsukasa forces the three out and they enter Natsumi to fight him, Decade uses Agito's power on each form while a mysterious Kamen Rider-like figure and his lackies attack a group of delivery men, with the Alligator Imagin taking advantage of the chaos. When a dimensional rift sends Decade and Den-O into the dimension where Natsumi saw the Rider War, the two Kamen Riders reach a stalemate as they are picked up by the DenLiner. While the DenLiner's Owner realizes that they have to work together, Yusuke and Momotaros as Den-O are in a losing battle against Diend with Narutaki as witness.
====Here Comes Super Momotaros!====
After getting on the DenLiner, Tsukasa takes pictures of the DenLiner's gang before the Taros. But after Kohana sets the three Imagin in their place, they suddently find the Hikari Studio as the front car.

====Cho Kamen Rider Den-O & Decade Neo Generations: The Onigashima Warship====
Taking place after the events of Kamen Rider Decade episode 15, under the impression that they saved the World of Den-O, Tsukasa Kadoya and company begin their journey to the World of Kabuto when they are halted by Sieg who presents them a manuscript that detailed the legendary Oni Conquest with Momotaros' image on it. As this occurred, the Tarōs mysteriously vanish from the DenLiner as they are about to help Kotaro Nogami out with the true threat to their world.
the DenLiner arrives at the Junction Point where they meet the Stationmaster who reveals a 1936 newspaper documenting that Urataros, Kintaros, and Ryutaros caught a band of rice thieves; they have been possessing the bodies of another trio named Jiro, Ramon, and Riki (the Arms Monsters of Kamen Rider Kiva). Traveling to that time, the kids find Tsukasa who offers his aid. Kotaro is reluctant to accept his help until Tsukasa reveals the scroll Sieg brought with him that has Momotaros on it,Arriving in the Muromachi period, DenLiner gang arrive and defeat the Gelnewts, meeting Toki and joining her at the village's pleas. 
The next day, after planning it out, the DenLiner gang gives up both the Trump Stone and the DenLiner. Once the Owner and Naomi are evicted, Kuchihiko ditches Kotaro as he enters the DenLiner to reach his brother in the present time period. However, his journey is staged as the evicted "Owner" is the Stationmaster in disguise as the real Owner pulled the emergency break as everyone else has erected a massive set designed to look like modern Tokyo. Once the DenLiner staff and the Stationmaster enter the train, with Kohana guarding the door, Den-O, the Tarōs, and New Den-O battle Goludora and the Gelnewts with Toki providing backup, until she is wounded in battle.
However, Diend appears long enough to summon Kamen Riders Ouja, G3, and Caucasus as wild cards in the fight and Kuchihiko reassembles the Oni's Trump Stone with Mimihiko activating the Demon's Warship in the present and using it to return to the past. The Oni Brothers are able to defeat them until Tsukasa and Sieg arrive, allowing Den-O to assume Wing form as Momotaros possess Tsukasa to fight as Decade. The other Tarōs do the same with Diend's summoned Riders (Urataros with G3, Kintaros with Caucasus, and Ryutaros with Ouja).
At Decade's suggestion, Ryotaro forms Kamen Rider Den-O Super Climax Form with the Tarōs and Sieg. Cho-Den-O and Decade manage to overwhelm the Oni Brothers with New Den-O Vega Form and Teddy's aid. After Shilubara sacrifices himself to protect his brother, an enraged Goludora enters the Warship and engages the DenLiner in a battle with Decade taking his leave as the DenLiner gang manages to sink the Warship from the inside out as Kamen Rider Den-O Sword finishes Goludora off with a Rider Kick. Soon after, Yu bids farewell to Toki as she is revealed to be his ancestor. Though offered a slight detour before they return to present, Yu turns it down as he wants to be back in his time. After they part ways, Deneb is dropped back in 2009 where he finds Yuto Sakurai waiting for him, where he reveals that he went by the name Yu as a child and they return to the ZeroLiner.

The DenLiner rendezvoused with the where Daiki was standing with Hina Izumi and Gokaigers Joe Gibken and Don Dogoier to get back the pudding. Picking up the four passengers, the DenLiner took them to Winter 1976 to pick up Akarenger.

====Heisei Generations FOREVER====
====2007: DenLiner Crash! ====
The Imagins are crashing at 9 5 DO when they request Junichiro Tokiwa's aid at repairing the DenLiner. It seems that the uncle is considered the best repairman of this era. Junichiro said that he only repairs clocks, but Urataros explains that the DenLiner is just like a giant clock, inciting his curiosity. Junichiro is still hesitating, however, but Ryutaros possesses him and alongside the other Imagins, they go to DenLiner, with a concerned Sougo in tow.
At the DenLiner, Junichiro notes that it indeed operates just like a giant clock. So, he will endeavor to repair it.
Zi-OTrinity cancels the transformation and Geiz immediately grapples with Momotaros in annoyance. Sougo notes that they don't know the arriving point of DenLiner, as Woz answers that they need the Den-O Ridewatch for that. Momotaros gives him said Ridewatch as he and his fellow Imagin had already created it, and it resonates with other 19 Heisei Ridewatches to form the GrandZi-O Ridewatch, as the others (except Woz and Momotaros) witness in horror.
====2017: Grand Climax!====
Ryutaros reappears, Momotaros cannot transform into Den-O as he gave his power to Sougo. He rants angrily, but Sougo summons Den-O from 2007, and Momotaros went on to possess him. He accessed Climax form to fight the Mole Imagins and alongside Zeronos Vega Form, quickly disposed of them.
Continuing the fight, GrandZi-O summons Build Genius form, Gaim Suika Arms, OOO Gatakiriba Combo and Kuuga Pegasus form. He pauses them again and now uses Build's Fullbottle Buster and his own Saikyo Zikan Girade to attack Another Den-O. As the Another Rider is stunned, the summoned Riders finished him, finally destroying Den-O Anotherwatch.

==Personality==
Ryutaros is childish in personality, having a love for drawing and animals. From his childish crush on Airi, Ryutaros affectionately refers to her as compared to Ryotaro's more formal . Ryutaros also enjoys break dancing, incorporating it into his fighting style. Whenever excited, Ryutaros asks something before following with a "I won't hear your answer!" . 
Selfish and spoiled at first, Ryutaros initially did things with little regard for others, excluding Airi Nogami. However, as he spent time with the Denliner crew, Ryutaros became more mindful in general, apologizing to his friends at one point when manipulated by Kai. 
He usually refers to Urataros and Kintaros as and respectively, excluding Momotaros as he's not based on an animal. He is referred to by the others as . Ryutaros is viewed as a sort of younger sibling by both Urataros and Kintaros and (at best) an irritant by Momotaros. After this initial arrival on the DenLiner, he is rarely seen without a pair of headphones over his head. Early promotional material stated that his form is based on the legend of Tatsu no Ko Tarō, or Taro the Dragon Boy. TV Asahi's website for Den-O states that his form is based on Ryotaro's mental image of dragons. 
When possessing a person, Ryutaros' vessels don a hip-hop look with purple eyes with matching streak in the hair, usually wearing a cap.

*Psychic Powers: An ability unique to Ryutaros, he can hypnotize a group of ordinary people with a single finger snap, something regularly done to show off his break dancing skills. For some reason, this also works on the DenBird as well, being used to summon it in battle as Den-O Gun Form.
===Weaknesses===
