Blank Form (ブランク体 Buranku-tai) is the form Ryuki takes when he does not have a Contract Monster. He possesses a generic arm-mounted Visor named the Ride Visor and a single Advent Card that summons the Ride Saber, a fragile sword that shattered upon its first use. It is much weaker than any of his other forms and any of the other Riders, though it still allows him to be in the Mirror World without disintegrating. Shinji began the series in this form before he contracted Dragreder, and reverted back to it when his Contract Card was stolen by Kamen Rider Gai.

- Kicking Power: 20 t (400 AP)

- Maximum Running Speed: 100 m per 5 seconds

Ryuki achieves his default form upon forming a contract with Dragreder. He is now equipped with the Drag Visor on his left arm and possesses a variety of Advent Cards. In comparison to the other Riders, his parameters are balanced.
Through the use of his Sword Vent Advent Card, Ryuki can arm himself with the Drag Saber (ドラグセイバー Doragu Seibā), a sword derived from Dragreder's tail. His Strike Vent arms him with the Drag Claw (ドラグクロー Doragu Kurō), a gauntlet capable of shooting fireballs that is derived from Dragreder's head. With the Drag Claw, Ryuki can perform the Drag Claw Fire (ドラグクローファイヤー Doragu Kurō Faiyā) attack with Dragreder, in which he and Dragreder each launch a fireball at the opponent. His Guard Vent equips him with the Drag Shield (ドラグシールド Doragu Shīrudo), two shields derived from segments of Dragreder's body that can be held by hand or mounted on Ryuki's shoulders.
By using his Final Vent, Ryuki can execute his finisher, the Dragon Rider Kick (ドラゴンライダーキック Doragon Raidā Kikku), in which he jumps into the air with Dragreder flying behind him. Dragreder then breathes fire at Ryuki, propelling him into a flying kick that strikes the enemy.

Kamen Rider Ryuki Survive (仮面ライダー龍騎サバイブ Kamen Raidā Ryūki Sabaibu) is Ryuki's final form, assumed by using the Survive Rekka Advent Card. The Survive Rekka card transforms the Drag Visor into the the Drag Visor-Zwei, which Ryuki uses to transform into Survive Form and read Advent Cards. Transforming into Survive form also causes Dragreder to transform into Dragranzer. Survive Form enhances all of Ryuki's stats, allowing him to surpass all other Riders, with the exception of those who are also using a Survive Advent Card, such as Knight Survive and Odin.
Using the Sword Vent Advent Card converts the Drag Visor-Zwei to a blade mode named the Drag Blade (ドラグブレード Doragu Burēdo).The Drag Visor-Zwei can also function as a ranged weapon by shooting fireballs. By using the Shoot Vent, Ryuki can perform the Meteor Bullet (メテオバレット Meteo Buretto) attack alongside Dragranzer, in which he and Dragranzer each launch a fireball at the opponent.
By using his Final Vent, Ryuki Survive can perform his final attack, the Dragon Fire Storm (ドラゴンファイヤーストーム Doragon Faiyā Sutōmu), which transforms Dragranzer into a bike for Ryuki to ride. Ryuki drives toward the enemy and performs a wheelie, followed by Dragranzer shooting several opponents at the opponent from its mouth. Finally, Ryuki slams into the opponent, destroying it.

Kamen Rider Decade's Final Form Ride allows Ryuki to change into Ryuki Dragreder (リュウキドラグレッダー Ryūki Doragureddā). This automatically equips Ryuki with Guard Vent and Sword Vent. While the first transformation required Decade's assistance, Ryuki eventually was able to transform at will into this form. Ryuki can also shoot fireballs from his mouth in this form.
Legend Rider Devices
Regained when Tsukasa and Shinji work together to defeat Kamen Rider Abyss, Kamata. Decade uses this card to assume Ryuki's Ryuki Form. Decade can also travel through mirrors like the original Ryuki and can summon the Drag Saber without the need of an Attack Ride Card.
These cards allow Decade to perform any of their own attacks, Decade is also able to use any signature attacks of whatever Kamen Rider he has transformed into.
- Strike Vent: As Ryuki, Decade summons the Drag Claw, a dragon-headed gauntlet that can send a burst of flames out of its mouth. Unlike the original Ryuki, it does not need Dragreder's assistance.
- Advent: As Ryuki, Decade summons the Contract Monster Dragreder. First used in Kamen Rider × Super Sentai: Super Hero Taisen.
- Guard Vent: As Ryuki, only in Battride War games, Decade can summon a pair of Drag Shields in battle.
When Kamen Rider Decade is in his Complete Form, he uses the K-Touch to summon the Final Forms of the Nine Heisei Riders. After he presses the Rider's symbol, a card of that Rider's Final Form appears in a set of nine on Kamen Rider Decade's chest. The Ryuki Survive card summons Kamen Rider Ryuki Survive, armed with the Drag Visor-Zwei. Using the Ryuki Final Attack Ride Card allows Decade to execute a Burning Saber-style attack alongside Ryuki Survive.
With Ryuki Dragreder flying behind to boost his attack's power, Decade performs the Decade Dragoon which is similar to Ryuki's Final Vent, the Dragon Rider Kick.
