Adam is the original Kamen Rider Dragon Knight from Ventara, he is the youngest of all the Ventaran Kamen Riders. Eleven of the twelve Kamen Riders were to sleep in cryogenic freeze while one stood guard. Adam grew tired of being a Rider and wanted a normal life. He betrayed his fellow Riders, giving Xaviax the way in to the capsules and he vented almost all the Riders except for Kase and Len, who escaped. Adam made a deal with Xaviax and Xaviax left Adam in a special dimension with his love Sarah, making her believe it was still Ventara. When Kit was vented and Xaviax stole the dragon deck, he went back to Adam to repay for his favor. Adam now must obey Xaviax or Xaviax will harm Sarah. Len and the others treat Adam like a traitor. When Kit is freed from the Void, Kit becomes Onyx and they fight. Eubulon breaks up the fight and gives Adam the benefit of the doubt. Adam claims he was tricked by Xaviax. Xaviax disguises himself as Eubulon and confronts Adam, calling him selfish and saying if Adam wasn't ready to be a Kamen Rider he never should have joined. Xaviax attacks Adam, continuing to berate him as they fight.

Adam gets now angry with Eubulon, Xaviax orders Adam to vent Len and fights Len. He tells Len there's no beating Xaviax, and he won't give up on Sarah for anything. Adam prepares to vent Len but can't bring himself to do it. Kit and Kase arrive, Adam tells them to vent him, but they refuse. Adam confesses that the transmitter aren't really shut down. Ultimately, Len takes the dragon deck from him and gives it back to Kit.
