Kamen Rider Decade

Kamen Rider Decade (仮面ライダーディケイド, Kamen Raidā Dikeido, Masked Rider DCD, Masked Rider Decade) is the title of the first of the 2009 editions of the long-running Kamen Rider Series of tokusatsu dramas. Decade, as its title suggests, is the tenth of the Heisei Rider Series, having begun with Kamen Rider Kuuga in 2000. It began broadcast the week following the finale of Kamen Rider Kiva and is featured in Super Hero Time alongside the 2009 edition of the Super Sentai Series, Samurai Sentai Shinkenger. The catchphrase for the series is "Destroy everything, connect everything." (全てを破壊し、全てを繋げ, Subete o hakaishi, subete o tsunage).

Synopsis

The story revolves around the nine previous universes of the Heisei Kamen Riders merging into one, something that would destroy all the worlds. To prevent this, Tsukasa Kadoya transforms into Kamen Rider Decade and is told that to protect his own world he must travel with Natsumi and her grandfather to the other Kamen Riders' Worlds (referred to as an A.R. World or Another Rider's World) and eliminate the anomaly in that world. Along the way, confronting the mysterious Narutaki and the thief Daiki Kaitoh, they are joined by Yusuke Onodera of the World of Kuuga and Kivala of the World of Kiva.

To fit with the photography motif of the series, the main Kamen Riders of the series follow the CMYK color model: Decade is magenta, Diend is cyan, and Kuuga (Ultimate Form) is black. While no specific Rider has been yellow, the armor of Kuuga Rising Ultimate is yellow (gold).

Rider War

The Rider Army (ライダー軍, Raidā Gun), first revealed in Natsumi Hikari's dream, composed of many Kamen Riders, all of whom where seemingly defeated by Kamen Rider Decade. However, Kamen Rider Kuuga survived the initial battle, assuming Ultimate Form to confront Decade once again with the two seemingly destroying each other in the ensuing battle. As Narutaki explains to Natsumi, the dream is a predestined event in which Decade will destroy all the worlds.

Upon the ending of the final episode it is stated that the Great Rider War will be continued in the form of a movie. Thus bringing the true end to the Decade series.
