Momotaros

"I...have arrived (at last/once again)!"

- Momotaros' pre-battle catchphrase

Momotaros (モモタロス) is one of the main good Imagin in the series Kamen Rider Den-O, and one of the Taros. As Ryotaro Nogami's first Imagin ally, he allows him to use Den-O's Sword Form. Momotaros eventually becomes the representative of the Den-O series, becoming Kamen Rider Den-O (仮面ライダー電王) himself.

History
Among the hundreds of Imagin that arrived to the year 2007, Momotaros entered the body of Ryotaro Nogami but unable to set up a contact; after initially being run over by Ryotaro's bike when offering the contract, he is forced to possess Ryotaro when he is attacked by Tetsuo. But after Ryotaro mentally restrains him, Momotaros learns that Ryotaro is a Singularity Point and helps him as Den-O to defeat the Bat Imagin. Admitting he does not remember their mission, Momotaros actually prefers fighting for his own whims. Though Ryotaro gives him his name rather than a desire to fulfill their contact, Momotaros eventually grew to respect the human as well as the other Imagin they are partnered with. In time, Momotaros begins to take his mission as member of the Den-Liner to protect time to heart.

In the Den-O series finale, due to Kintaros granting Ryotaro's unintentional wish for the Taros to stay by his side, Momotaros and the others are able to be present alongside Ryotaro for the final battle with Momotaros accepting Ryotaro's actual wish to fight with him to the very end. After the battle ended, with his existence assured, Momotaros was distant and silence over parting ways with Ryotaro, only to jump to the window at the last second to say goodbye to his friend while promising to meet again as the Den-Liner departs back into the timestream.

That promise is kept during the events of "Final Countdown" when Momotaros is stunned to be fighting Ryotaro while he's possessed by the Ghost Imagin, nearly getting himself killed to free his friend as they fight together against Shiro with Ryotaro's grandson aiding them. Later, he becomes a hot-blooded member of the Den-Liner Police that is formed to battle Negataros. Though Negataros was destroyed, Momotaros keeps the new group together as he sees being a cop as a cool thing.

Decade and Cho Den-O movies
When the recently de-aged Ryotaro leaves to investigate the Oni disturbance in the past, Momotaros loses his physical form and memory as he possesses Yusuke Onodera, allowing him the ability to transform into Den-O Sword Form. However, Momotaros finds himself being attacked by Daiki Kaito who wants Den-O's powers. But when he teamed up with Tsukasa Kadoya, Momotaros regains his memories and physical form while Kamen Rider Decade acquires the Den-O Kamen Ride, Final Form Ride and Final Attack Ride Cards.

Though Decade thought he solved the issues in the main rider continuity (Den-O's world), time was still awry as Momotaros gets sent to the past in the Oni War, which the Den-O team and Decade fight in to ensure that the Oni from years past are exterminated, as history says. Sometime later, the Den-Liner gang face Daiki again when he uses them to steal a treasure in the past.

Let's Go Kamen Riders
Momotaros and the crew of the DenLiner encounter Eiji Hino/Kamen Rider OOO and the Greeed Ankh. Unfortunately, Ankh unintentionally altered the timeline which enabled Shocker to utilize the Core 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, as even though Rider history was changed, the people's memories haven't changed.

After Teddy returned, Momotaros became Den-O and assumed Climax Form when Urataros, Kintaros, and Ryutaros asked to join in, doing so until all the riders joined up. After the riders were united, they faced off against Shocker's Great Leader. Ankh used Momotaros to create the Imagin Core Medal, which allowed OOO to assume Kamen Rider OOO Tamashii Combo and defeat the Great Leader, though he soon came back as the Rock Great Leader. Later, when joined by a force of extra riders, Den-O 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. After it was over, everyone went their seperate ways and Momotaros returned to the DenLiner which embarked on its next destination.

Super Hero Taisen
Momotaros discovered Daiki holding up the stolen cup of Den-Liner Purine pudding that he stole from him during their last meeting. The Den-Liner 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 Den-Liner took them to Winter 1976 to pick up Akarenger. While getting their guests there, debating over whose side they are on, Momotaros said that he was the leader of the "Imagin Sentai" because he was the. When the Sentai teams and the Kamen Riders battle the Shocker-Zangyack Alliance, Momotaros and the other Taros join the fray in their Den-O forms, fighting alongside the. Momotaros chided Urataros for flirting with in the middle of the fight. Momotaros later joined with other Kamen Riders to fight Doktor G, they were all overpowered by his Kani Lazer form until he was defeated by Kamen Riders Decade, Blade, and Ryuki, with a little help from the.

The combined forces of superheroes were able to turn the tide against the Madou army. They lined up and used their various finisher attacks to destroy the revived monsters.

DenLiner, but he is displeased because Kyoryu Red takes over the upper body, knocking the DenLiner down to being the feet. After battling the Badan Empire, Hongo stated that their battle wasn't over as the Rider War continues. However the Showa Riders admit their defeat after seeing Gaim protecting a flower as they would congratulate the young Riders.

Due to the timeline alteration caused by Shocker, Den-O became one of the brainwashed Riders in that timeline, donning the name of Shocker Rider Den-O.

Following the Rider Grand Prix in which Drive emerged victorious over Rider 3, who was promptly integrated into the Great Leader of Shocker's Rider Robo form, Den-O was among the Riders who attacked the trio of Black RX, Faiz and Mach. Ultimately, the Double Riders 1 and 2 made their appearance having survived their apparent demise from within the Rider Robo, and broke Shocker's brainwashing on the fallen Riders, enabling all Riders to unite in a final battle against Shocker.

Personality
"From start to finish, I'm a climax all the way!"

- Momotaros Influenced by Ryotaro's image of Momotarō, the Peach Boy, Momotaros was originally annoyed of looking like a red Oni though it matches his hot-blooded and prideful personality. Though he can be seen as a foil to Ryotaro's own shy and cowardly personality, Momotaros suffers comedic conflict in various ways; one being getting into fights with the other Taros members and the other being constantly beaten by Hana when he causes trouble.

Momotaros can also sense when an Imagin is rampaging in the city, subsequently alerting Ryotaro immediately. His natural weapon as an Imagin is a sword named the Momotarosword (モモタロスォード).

When he possesses Ryotaro, declaring the words "I...have arrived!" (俺、参上！) Momotaros' own personality takes over, giving Ryotaro a boost in strength and controlling his body. A variant of this is when Momotaros transforms into Kamen Rider Den-O Sword Form, where he occasionally says "I...have arrived again!" (俺、再び参上！). His eagerness is shown in battle, where he always declares the words, "From the start (to the finish), I'm at a climax!" (俺は最初から（最後まで）クライマックスだぜ！). Momotaros is also somewhat selfish, initially fighting alongside Ryotaro in order to ensure his own survival.

Though he unknowingly places Ryotaro in unneeded danger to suit his fancy, Momotaros eventually learns to respect him and his desire to protect others. Though he demands respect, Momotaros is usually put in his place by Hana and her powerful punches. He also does not know how to swim, has strange reactions to red peppers, and is terrified of dogs. Interesting to note is that Momotaros may have as much if not worse luck as Ryotaro as he later on had to deal with a strained back, been left in a time where he had to act as a homeless for four weeks, broke his foot and was unable to fight and being the only one who's parachute didn't open when Ryotaro and the others escaped the time police. While he acts hostile and demeaning to the other Tarōs, he does care about them, proven by hiding his anguish while they are slowly disappearing due to the events of the Climax Scene. This is fully shown when he was driven to tears when the rest of the Taros reappeared to help him and Ryotaro. He is also different from most Imagin as he helps those who are emotionally troubled by offering advice in his own way. Momotaros often allows his feelings to get the best of him, and can quickly become stronger or weaker depending on his feelings.

Phrases

In his battle against Kamen Rider Gaoh, Den-O Sword Form swiped the Rider Pass over the Den-O Belt twice, initiating a doubled Full Charge for "My Special Attack, Special Edition" (俺の必殺技・特別編). During the fight with the Death Imagin, with aid of the other Taros, Sieg, and Zeronos adding their power into his blade, Momotaros called it "My Special Attack, Final Version" (俺の必殺技ファイナルバージョン). During the fight with Kuchihiko as Goludora, Den-O Sword Form unleased a series of tachyon-powered Rider Kicks dubbed by Momotaros as "My Super Special Attack" (俺の超必殺技).
