The Onyx armor is accessed via a black-colored clone of Dragon Knight's Advent Deck, newly created by Eubulon and contracted to Dragblacker. Being a copy of Dragon Knight, Onyx possess the same abilities and combat potential as the former, while its Advent Card stats appear to have higher power presumably to make up for the lack of a Survive Mode card. This, along with Kit's growing fighting experience, make Onyx a skilled and formidable warrior, even being able to overpower the original Dragon Knight at some point.
Through the use of his Sword Vent Advent Card, Onyx can arm himself with the Dragsaber, a sword derived from Dragblacker's tail. His Strike Vent arms him with the Dragclaw, a gauntlet capable of shooting fireballs that is derived from Dragblacker's head. With the Dragclaw, Onyx can perform the Dragclaw Fire attack with Dragblacker, in which he and Dragblacker each launch a fireball at the opponent. His Guard Vent equips him with the Dragshield.
By using his Final Vent, Onyx can execute his finisher, the Dragon Rider Kick, in which he jumps into the air with Dragblacker flying behind him. Dragblacker then breathes dark blue fire at Onyx, propelling him into a flying kick that strikes the enemy.
