Kamen Rider Yuuki Skull Form

The 3rd Kamen Rider Den-O movie introduces Kamen Rider Yuuki (仮面ライダー幽汽, Kamen Raidā Yūki^?), an evil Kamen Rider system of those who have control over the Ghost Train (幽霊列車, Yūrei Ressha^?), a skull-faced steam-engine that transcends the world of the dead and the flow of time.

The Yuuki system's Kamen Rider Gaoh-like armor has an aged appearance, with rust and numerous scratches dotting its surface, keeping with the overall theme of death along with elements of the samurai and steam trains.

Ghost Imagin

The Ghost Imagin (ゴーストイマジン Gōsuto Imajin?) is one of Shiro's Imagin followers and possesses Ryotaro, having him assume Kamen Rider Yuuki Skull Form. While possessing Ryotaro, Ryotaro is referred to as "A-Ryotaro" (A良太郎 Anazā Ryōtarō?), with the A standing for "Another". He later destroyed by Den-O Climax Form's Charge and Up - Extreme Slash: Climax Version.
