Dragon Knight Onyx

Dragblacker is a black Japanese dragon that is a dark copy of Dragredder, and Kamen Rider Onyx contract beast.

Onyx's Advent Deck

Like Dragon Knight, Onyx slots his cards on the dragon-like slot on his left arm called the Black Drag Visor.

• Attack Vent: Summons Dragblacker to directly attack his opponents.
• Sword Vent: Conjures a black dragon-designed broadsword.
• Strike Vent: Attaches a black dragon-like gauntlet on his right hand to shoot a burst of black flames assisted by Dragblacker.
• Guard Vent: Attaches black dragon-like guards on his arms.
• Final Vent: Summons Dragblacker for Onyx's Final Vent. It consists of Onyx jumping into the air to emit dark energy that paralyzes the opponent's legs and then deliver a flying side kick with Dragblacker flying behind to boost the attack's power with its dark flame.

Onyx Survive Mode Advent Deck

Onyx Survive Mode never appeared on the show, but had a toy made. Onyx's slot changes from his arm slot to a dragon-like gun called the Black Drag Visor-Zwei. The Survive card is inserted inside the dragon mouth and the cards are slotted on the side of the slot.

• Attack Vent: Summons Dragblanzer to directly attack his opponents.

• Sword Vent: Opens a blade on the slot (similar to a pocket knife).

• Shoot Vent: Summons Dragblanzer who shoots a burst of flames.

• Guard Vent: Dragblanzer coils around Onyx which protects him from attacks.

• Strange Vent: An odd card which, upon being slotted, will become any card that any of the other Riders use (often the next card in their decks). The new card must be reslotted to use.

• Final Vent: Summons Dragblanzer for Onyx Survive Mode's Final Vent. Onyx Survive Mode lifts in to the air and lands on Dragblanzer back ,he is then completly covered in Dark energy. Dragblanzer then swoops down and knocks the enemy in the air. Onyx and Dragblcker sart flying up ,then Dragblacker wraps around Onyx and the enemy and startes to dive toward the ground, at the last second Dragblanzer lets go of the Onyx and enemy. Onyx then finishes the enemy off like his normal Final vent with Dragblanzer
