Adam was Kamen Rider Dragon Knight, and Kit's Ventaran counterpart, who had "betrayed" the other Kamen Riders by venting them into the Advent Void (save for Kase and Len) into helping Xaviax take over Ventara so he can be with his girlfriend, Sara. Adam wanted to retire from being a Kamen Rider after Eubulon disappeared, which Xaviax promised to do after venting the other Riders. Not wanting to fight anymore after betraying his fellow Riders, he secludes himself with Sarah in an illusion created by Xaviax until he is called upon again after all the Riders but Len are vented.
