Kamen Rider Onyx may refer to any the following characters. A black-colored version of Dragon Knight contracted to Dragblacker, Onyx possesses the same abilities and combat potential as the former; however, Onyx is relatively stronger than Dragon Knight, due to his Advent Cards having a higher AP. This is shown when Kit as Onyx manages to overpower Adam, the original Dragon Knight, in episode 34. The only disadvantage of the Onyx form is the lack of a Survive Mode card.
