When Kit grew jealous of Len's companionship with Kase, more about the history than the actual romantic relationship, he started having nightmares. In these nightmares, Kit as Dragon Knight fought Kase and Len in their Rider armors separately. And he would transform into a black version of Dragon Knight called Onyx. Xaviax stole the dragon deck and gave it to Adam after venting Kit Taylor. Eubulon took Kit Taylor out of the void and since the original Dragon Knight Adam was given the deck back, Kit was given the Onyx deck. Kit was hesitant because he had nightmares of him as Onyx venting Kase and Len before he was vented. Kase, Eubulon, Len, Chace, Price, and Hunt told him to get over it, that the contract beasts create nightmares before they get tamed. The Contract Beasts get tamed when they are contracted and the nightmares fade away. From then on, Kit then fought as Kamen Rider Onyx, but did not trust Adam. After Xaviax was defeated, Adam left the Kamen Riders, Eubulon gave Kit the choice between the Onyx and Dragon deck and he chose to continue fighting as Kamen Rider Dragon Knight, his dad was revived by Eubulon.
