Kamen Rider: Dragon Knight is an American television show originally aired on The CW during its CW4Kids programming block from December 13, 2008 to December 26, 2009. It is an adaptation of the Japanese tokusatsu show Kamen Rider Ryuki and is the second Kamen Rider show to be adapted and completely produced by an American TV production company, the first being Saban's Masked Rider. It was brought to television by Steve and Michael Wang and produced by Jimmy Sprague through Adness Entertainment. The 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.
