- "Advent, to the top..."
- ―Sieg's pre-battle catchphrase[src]
Sieg (ジーク Jīku) is an Imagin who is unofficially the fifth part of the Den-Liner crew, providing Ryotaro Nogami with Den-O's Wing Form.
Kamen Rider Den-O
Sieg arrived 6 months prior to Ryotaro becoming Den-O, originally intending to forge a contract with a young wealthy woman named Shiori Takayama. But she was pregnant and Sieg ended up inside the baby in a deep sleep until he emerges in physical form with no memory of the wish and believes that he forged a contract with the baby, Yusuke, instead of Shiori as he had planned. Sieg took his "brother" out of the strange area he found them in, only to meet Ryutaros who takes Sieg to the Den-Liner, where the Imagin got his own sleeping car with a lavish bed and Ryutaros helped fill it with stray puppies and kittens. After a series of events that clear Ryotaro of Yusuke's abduction, Sieg uses the human's body to reap the benefits of living with the Takayama family
However, because Yusuke's mind is too young to maintain his existence, Sieg begins to fade away, but not before becoming Den-O Wing Form to fight the Scorpion Imagin. After the Scorpion Imagin is defeated, Ryotaro returns with a Rider Ticket that he got from Shiori that bore the date June 1, 1997, revealing that Sieg did have a contract with her. He then remembers Shiori's wish for her baby to be born safely, fulfilling that contract. With the Den-Liner gang's help, Sieg arrives in the past to live peacefully.
Kamen Rider Den-O: I'm Born!
However, during the hijack of the Den-Liner, Sieg offers his aid to Ryotaro in the Tarōs' stead as only he could possess Ryotaro's body, deciding to repay his debt to Ryotaro for preventing his disappearance.
He battled the Cobra Imagin in the Edo period while befriending Kotaro. He would aid the Den-Liner gang two more times, aiding in Ryotaro getting stronger and later to assist Ryotaro and the others in defeating Kai's army of Imagin after being retrieved by Naomi. But due to his birth and time with Ryotaro creating a time lag, Sieg is able to maintain his existence as he takes leave in the Den-Liner.

Super Climax Form (超･クライマックスフォー Chō Kuraimakkusu Fōmu), originally advertised as Kamen Rider Cho Den-O (仮面ライダー超・電王 Kamen Raidā Chō Den'ō), is Den-O's eighth and true final form, exclusive to the Cho-Den-O Series and first appearing in Cho Kamen Rider Den-O & Decade NEO Generations: The Onigashima Battleship. It is identical to the original Climax Form in being a stronger version of Sword Form that incorporates the DenKamen of the other three primary Den-O forms onto various parts of the armor. However, Cho Climax Form also includes Wing Form as wings on the back of Den-O and a Wing Form insignia on the mask. It is also physically stronger than Climax Form and has the ability to use the wings to fly up and execute a stronger version of Climax Form's Rider Kick.
It should be known that Sieg's participation in this form is likely due to him possessing the de-aged Ryotaro when Momotaros invoked the Climax Form, thus making his part "unnatural". However, he participated in this form again in Kamen Rider × Kamen Rider W & Decade: Movie War 2010 when Kamen Rider Decade assumed Strongest Complete Form, which influenced the other Riders in their final forms, as well as Den-O, turning into Super Climax.
