Kamen Rider Dragon

While searching for his missing father, Kit Taylor finds an Advent Deck – a special card deck that allows the carrier to transform into a Kamen Rider and utilize unique weapons and powers – and uses it to become Kamen Rider Dragon Knight. He butts heads with Len, who serves as Kamen Rider Wing Knight, but the pair join forces after Kit learns that the wicked General Xaviax has imprisoned his father and is using him and the other humans that his monsters abduct to gain power and rebuild his homeworld. Xaviax tricks people on Earth to work for him by promising them whatever they want. Kit wonders why Xaviax has to trick them and why he doesn't just find bad guys to do the work for him. Len tells Kit that the decks were only made for one person, and that only a person with an exact DNA match as the original Ventaran rider could use it. Later on Kase, a fellow survivor of Ventara like Len, joins forces with Len and Kit to fight Xaviax. In addition to training Kit to fight like a Rider, Len and Kase tell Kit all about the thirteen Riders who banded together as the protectors of Ventara – a world opposite to our own – to take Xaviax down. However, due to the traitorous actions of Kit's predecessor, Adam, General Xaviax destroyed most of the Riders via a process called Venting – which traps defeated Riders in the "Advent Void" between dimensions forever – and stole their Advent Decks. Furthermore, Xaviax continues to send out his Riders who fight to eliminate Kit, Len, and the other Riders who oppose him. After Kit is Vented, Xaviax recruits Adam to once again become Dragon Knight. Meanwhile, Len uses his Advent Deck to awaken the Advent Master Eubulon, who brings back the Ventaran Kamen Riders from the Advent Void, including Kit who becomes Kamen Rider Onyx. He also brings back Kase, who is hurt and allows Eubulon to reassign the Advent Deck to Maya Young. Once Kase is better, Maya gives back the deck and the riders head for Xaviax's base to destroy him.
