The series was developed for television by Power Rangers alumni Steve and Michael Wang and produced by Jimmy Sprague via Adness Entertainment.

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 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.

Once Kase is better, Maya gives back the deck, and the Riders head for Xaviax's base to destroy him.

[10] According to early licensing information for the series, Adness Entertainment had intended to also film a feature-length movie for Dragon Knight.

[13] Steve employed his brother Michael and long-time friend Nathan Long to write the show.

Long and the Wang brothers wrote the story and structure of the show to connect with the action/effects footage of Kamen Rider Ryuki, a technique done in previous Americanizations such as Godzilla, King of the Monsters!, Power Rangers and Saban's Masked Rider.

[15] Dragon Knight was shown in Brazil on Rede Globo during its TV Globinho programming block before being replaced by a re-run of Dragon Ball in September 2009[16] (due to the early and daily exhibition); Brazil's Cartoon Network was then the only venue airing the show until it came back to TV Globinho as a part of its Saturday Morning timeblock in January, 2010.

[19] The dubbed version of the series also aired on Indonesian's free-to-air TV channel Indosiar on Sunday mornings at 6:00 am (UTC+07:00).

Previous actors from the Kamen Rider franchise who lend their voices to the cast include: On TV Asahi affiliate broadcasts of the Japanese-dubbed Dragon Knight, the song "Dive into the Mirror" by defspiral, is used as the opening theme.

The group also performed as Wilma-Sidr for Kamen Rider W. The song "ANOTHER WORLD", sung by Tatsuhisa Suzuki and Satoshi Matsuda under the pseudonym "Kit×Len", was used as the ending theme.

In addition to airing outside the United States, Kamen Rider: Dragon Knight is available on DVD in certain countries.

In Brazil, 13 DVD Volumes containing all 40 episodes were released by PlayArte Home Video even though their site only lists the first two.

[34] There are no current plans to release Dragon Knight in the United States, despite the release of several of the Japanese Rider series, including Kamen Rider Ryuki, the series from which Dragon Knight draws its footage, on Blu-Ray in the US.

A sequel novel titled Kamen Rider Dragon Knight: 2WORLDS 1HEARTS was released exclusively in Japan on September 16, 2010.

A fighting game based on the series was released for the Nintendo DS and Wii platforms by D3 Publisher on November 17, 2009.

If the game is played with Wrath, who is possessed by Xaviax, the player faces Dragon Knight in Mirror World and Onyx in Arcade mode.

Unlike the single player-only DS version, the Wii release supports up to two players.
