Kamen Rider: Dragon Knight 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 an alien warlord named General 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...
