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 Momotarosu) 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 Denrainā), supposedly allowing Den-O to transform into a form similar to DenLiner Gouka, but it changed to Den-O
