Kamen Rider Den-O (Rider)

Kamen Rider Den-O (仮面ライダー電王) is the primary protagonist and eponymous character of the 2007 Kamen Rider Series, Kamen Rider Den-O. The name Den-O belongs to any of seven of the characters forming Kamen Rider Den-O, either by himself, as a combination of two characters or a melee of four or five.

Riders

 * Ryotaro Nogami - Ryotaro is the host body for the Tarōs' Rider forms as well as a rider of his own right having personal Plat Form and later Liner Form.
 * Kotaro - the eleven-year-old version of Ryotaro. Becomes Mini Den-O when possessed by Momotaros.
 * Kotaro Nogami - intended to be the new Den-O. He is a non-Imagin-possessed Rider but may also be possessed by Deneb to attain Vega Form. Though Den-O in name, he is New Den-O in all promotional material to distinguish him from the original Den-O system.

Decade Forms
Like in the original series, one who become Den-O has access to four basic forms based on the Imagin in control of the possessed human: Momotaros allows for Sword Form, Urataros allows for Rod Form, Kintaros allows for Ax Form, and Ryutaros allows for Gun Form. The Swan Imagin Sieg, who allows for Den-O to become Wing Form, can join the Tarōs in achieving the stronger Super Climax Form. Den-O's Final Form Ride Card, Momotaros (モモタロス) provides Momotaros with a physical body, ejecting his host. Unlike previous Final Form Ride cards, this one stays in effect even after Decade has reverted to Tsukasa. The card was initially in the possession of Diend as Denliner (デンライナー), supposedly allowing Den-O to transform into a form similar to DenLiner Gouka, but it changed to Den-O Momotaros upon Decade snatching the card from Diend.

Other Riders with the same Plat Forms

 * Negataros
 * Gaoh
 * Kamen Rider Yuuki
 * Kamen Rider G Den-O

Rider Cards
Several Rider Cards allow Tsukasa Kadoya/Kamen Rider Decade to access the power of Den-O.
 * Kamen Ride Card: Regained when Tsukasa refers to Momotaros by his real name after calling him kind-hearted and restoring his sense of self. Decade uses this card to assume the form of Den-O's Sword Form. A Kamen Ride: Den-O card is also possessed by Diend, which he uses to summon Den-O. First used in the World of Hibiki. When he is summoned, he first says "Here I Come!"
