Dragreder is a red mechanical Japanese dragon which is Dragon Knight's Advent Beast. When Dragon Knight activates his Survive Mode card, Dragreder evolves into Dragranzer, a dragon that can turn into a motorcycle.
Dragon Knight slots his cards on the dragon-like slot on his left arm called the Dragvisor. As Blank Knight, the design of the slot, called the Ridevisor, was more generic but worked the same way.
- Attack Vent: Summons Dragreder to directly attack his opponents.
- Sword Vent: Conjures a dragon-designed broadsword. As Blank Knight, it was a normal, generic longsword that broke easily.
- Strike Vent: Attaches a dragon-like gauntlet on his right hand to shoot a burst of flames, assisted by Dragreder.
- Guard Vent: Attaches dragon-like guards on his arms.
- Final Vent: Summons Dragreder for Dragon Knight's Final Vent. It consists of him jumping into the air, delivering a flying side kick powered by Dragreder's flames.
- Survive: Allows Dragon Knight to access Survive Mode and transforms Dragreder to Dragranzer. When activated, the background of the card shines with a spinning red flame effect.
- Link Vent: Unites and unleashes the power of all 13 Final Vents.
Dragon Knight's slot changes from his arm slot to a dragon-like gun called the Dragvisorzwei. The Survive card is inserted inside the dragon mouth and the cards are slotted on the side of the slot.
- Attack Vent: Summons Dragranzer to directly attack his opponents.
- Sword Vent: Opens a blade on the slot (similar to a pocket knife).
- Shoot Vent: Summons Dragranzer who shoots a burst of flames.
- Guard Vent: Dragranzer coils around Dragon Knight 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.
- Trick Vent: Creates several copies of Dragon Knight.
- Final Vent: Summons Dragranzer for Dragon Knight Survive Mode's Final Vent. Dragranzer transforms into a motorcycle that Dragon Knight rides on as it shoots fireballs at its enemies while ramming into them.
