Dragreder (Ryuki)

The Dragreder is a creature most commonly summoned by the titaluar rider in Kamen Rider Ryuki.

Appearance
Dragreder appears as Ryuki's Contract Monster. He resembles a mechanical Japanese dragon. Ryuki uses him for his weapons and for combination for Survive Final Vent.

History
Dragreder was along with every other Mirror World Monster, created from Yui's and Shiro's Pictures when they were younger.

Dragreder initially appeared in Episode 1 and was originally a rampant Mirror Monster that was targeting Shinji. However, Shinji was eventually able to form a Contract with it, become Kamen Rider Ryuki.

For most of the Series, Dragreder did not play an integral part and instead was simply used when Ryuki wished to perform Strike Vents and Final Vents

With the gaining of the Survival Card, Ryuki was able to change into Survival Form and hence, Dragreder was able to evolve into Dragranzer, A much more Powerful Dragon. He then assisted Ryuki with Shoot Vents as well. With this evolution, Dragranzer was also able to transform into a Motorcycle which Ryuki would use to complete his Final Vent.

It is unknown what happened to Dragreder after Shinji's death as it did not become rampant. But, Because of Shiro's Time Reversal to a Time where Mirror-World didn't exist, we can also assume the same for Dragreder.

Uses

 * When Strike Vent is activated by Ryuki, Dragreder appearas and shoots a fireball in the direction that Ryuki points.
 * When Sword Vent is activated, Ryuki gain's a Sword similar to Dragreder's Tail
 * When Guard Vent is activated, Ryuki gains a Shield that resembles Dragreder's underbody
 * When Final Vent is activated by Ryuki, Dragreder shoots an airbourne Ryuki into an opponent by exhaling a fireball behind him for extra power.

Survive
Once Ryuki uses a Survive Card, Dragreder evolves into Dragranzer and gains a new range of card abilities as well as generally becoming more powerful.
 * This evolution also allows Dragranzer to transform into a motorbike, which is commonly used for Survive Ryuki's Final Vent.
 * Dragranzer also assists with Ryuki's Shoot Vent like he did before, only now the fire comes out of Ryuki's Drag Visor Zwei.
 * When using Guard Vent, Dragranzer coils itself around Ryuki.
