Darkwing

Darkwing appeared in 2002 TV series called Kamen Rider Ryuki. The Wings of Darkness Darkwing (闇の翼ダークウイング Yami no Tsubasa Dāku Uingu) is the Contract Monster of Kamen Rider Knight.

Darkwing, along with every other Mirror Monster was created by Yui's and Shiro's pictures during their childhood.

It is shown that Darkwing was initially used in one of Shiro's initial experiments and is assumed to be the Mirror Monster responsible for Eri going into a coma. Multiple times throughout the series, Darkwing acted as though it was targeting Eri. Each time Ren shooed it away. Most of the time however, it was there simply to assist Ren in battle. Followed by Knight's transformation into Survive Mode, Darkwing as well transforms into Darkraider.

It is unknown what happened to Darkwing but considering Mirror World didn't exist after the final Time Vent, it can be assumed that it didn't exist.

It is notable for being one of the Contract Monsters that can be summoned without using an Advent, just like Dragreder.

In the World of Ryuki, Darkwing assists Knight as Contract Monster in the Kamen Rider Trial. His only appearance was when Knight was performing his Final Vent attacks.

Roles in Advent Card Attacks

 * Sword Vent: Darkwing's tail becomes the Wing Lancer (ウイングランサー Uingu Ransā).
 * Guard Vent: Darkwing attaches to Knight's back and becomes the Wing Wall (ウイングウォール Uingu Uōru) cape-like shield.
 * Nasty Vent: Darkwing performed the Sonic Breaker (ソニックブレイカー Sonikku Burekā), an attack involved by unleashing a painful ultrasonic screech.
 * Final Vent: Knight and Darkwing perform Hishozan (飛翔斬 Hishōzan). Darkwing lands on its master's back to form a cape as he leaps into the air, wrapping himself with the cloak as they descend in the form of a drill using Wing Lancer as the tip to impale the opponent.
