Kamen Rider: Dragon KnightThe series had a sneak premiere on December 13, 2008 and began official broadcasting on January 3, 2009, then continued throughout the year. Adness chose to adapt Ryuki over the other Heisei Rider shows as it has a large number of characters (Ryuki had 13 Riders in total) as well as a female Rider. The CW had dropped Dragon Knight at the end of the year before its final two episodes aired in the US. The final episodes were uploaded to the 4Kids TV website on December 18, 2009. In 2012, all of the episodes were removed from the 4Kids TV website. In 2010, Dragon Knight was nominated for and won the Daytime Emmy Award for “Outstanding Stunt Coordination”, a category introduced to the Daytime Emmys that year.
Kamen Rider: Dragon KnightWhile 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 an alien warlord named Xaviax is responsible for his father’s disappearance and intends on abducting him and the entire human race to gain power and rebuild Xaviax’s homeworld. Xaviax tricks people on Earth into working for him by promising them whatever they want, or in some cases, by exploiting their fears and desperation. 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 to the original Ventaran rider could use it. This is why Kit is able to use the Dragon Knight Deck: he is the exact Mirror Twin of Adam, the original Dragon Knight, who betrayed the original team. One of the new Earth Riders, Chris Ramirez (serving as Kamen Rider Sting and tricked by Xaviax into believing he is working in a special ops government program to fight alien invaders), joins forces with Kit and Len when he discovers he has been deceived, but is Vented—a process which traps defeated Riders in the “Advent Void” between dimensions forever and removes their Advent Decks—along the way. Kit vents Albert Cho, brother of Danny Cho, in retaliation. This leads to a personal hatred between Danny and Kit, as Danny seeks to avenge his brother against Xaviax’s orders.
Kamen Rider: Dragon KnightLater, Kase, a fellow survivor of Ventara like Len, joins forces with Len and Kit to fight Xaviax. In addition to training Kit as a Kamen Rider, Len and Kase tell Kit all about the twelve Riders who banded together as the protectors of Ventara—a world opposite to our own—to take Xaviax down. However, due to the unintentionally–traitorous actions of Kit’s predecessor, Adam, Xaviax vented most of the Riders. Furthermore, Xaviax continues to send out 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. Unlike when Xaviax convinced Adam to ‘betray’ the Riders by playing to his desire to remain with the girl he loved, Xaviax now uses a combination of blackmail and using Adam’s girlfriend as a hostage in order to force Adam to work for him.
Kamen Rider: Dragon KnightMeanwhile, Len uses his Advent Deck to awaken the Advent Master Eubulon—who brings back the Ventaran Kamen Riders from the Advent Void—and Kit, who becomes Kamen Rider Onyx. He also brings back Kase, though Eubulon is forced to briefly reassign the Advent Deck to Maya Young while Kase is trapped in the Advent Void. Once Kase is better, Maya gives back the deck and the Riders head for Xaviax’s base to destroy him. In the end, all the Ventaran Riders regain their decks, while all the Earth Riders (except Kit) have been released from the Advent Void & have their memories erased and returned to their normal lives, leaving Kit as the true owner of the Dragon deck after the previous owner Adam retires his deck thus officially becoming Kamen Rider Dragon Knight & the only active Earth Kamen Rider, leaving the Onyx deck inactive. But as the remnants of Xaviax’s army and other dangers continue to threaten Ventara & Earth, Kit, along with Len, Kase and the other riders continue to protect both planets
