Faiz riding the Auto Vajin.

The Transforming-type Variable Vehicle SB-555V Auto Vajin (可変型バリアブルビークル SB-555V オートバジン, Kahen-gata Bariaburu Bīkuru SB-555V Ōto Bajin) is a transforming, artificially intelligent support mecha for Kamen Rider Faiz seen in the 2003- 2004 Kamen Rider Series installment Kamen Rider 555. It is the first of the support mecha seen in the series, which can transform from a Smart Brain motorcycle (Vehicle Mode) into a flight capable robot (Battle Mode).


A variable vehicle made by Smart Brain Motors, a subsidiary of Smart Brain, the Auto Vajin is Kamen Rider Faiz's personal mecha. It has a limited A.I., but it is programmed to protect Mari Sonoda and do as Faiz commands, in that precise order. If the person wearing the Faiz Gear attacks Mari, the Auto Vajin will attack Faiz.

In addition to being able to transform willingly by pressing a switch on the chest, automatic transformation is possible by the function of a large capacity HDD with the next-generation high-speed CPU and Smart PC Ⅳ (スマートPC Ⅳ Sumāto PC Ⅳ) installed in it. It also has a high self-learning function, supports Faiz independently.

Initially it was fairly incompetent in its duties, accidentally shooting Faiz on a few occasions, but it became a valuable asset later in the series, often putting itself in harms way to protect various characters, and coming to the rescue when Faiz is in great danger. The Auto Vajin also carries the Faiz Edge, which serves as the left handlebar (on its right shoulder in Battle Mode) of the Auto Vajin.

The Auto Vajin was destroyed by the Orphnoch King in the final episode of the TV series and by the Elasmotherium Orphnoch in the movie Paradise Lost, but was repaired sometime before Kamen Rider × Super Sentai: Super Hero Taisen and Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai.

Later history

As evident in Faiz's later appearances, it would appear the Auto Vajin was rebuilt at some point.

Super Hero Taisen

In the supposed final battle between the Kamen Riders and Super SentaiIcon-crosswiki.png, Faiz rode on the Auto Vajin with the other surviving Kamen Riders (Kuuga, Kabuto, Kiva, and Double) on their respective motorcycles, led by Rider 1 (actually Decade in disguise) on the New Cyclone. Faiz used the Auto Vajin to attack the Dai Sentai Goggle-VIcon-crosswiki.png as Kuuga on the TryChaser 2000 attacked Choujuu Sentai LivemanIcon-crosswiki.png. They then turned towards AkarengerIcon-crosswiki.png (actually Gokai RedIcon-crosswiki.png) as he was attacking Kabuto, only to be knocked off their bikes by his Spear ButeIcon-crosswiki.png. The three riders were seemingly defeated, actually sent to the Dimensional wall. [Kamen Rider × Super Sentai: Super Hero Taisen]

Kamen Rider Taisen

While Takumi was on a journey, Tsukasa recruited him in a fight to protect the world against the Underground Empire Badan, which Takumi refused. When protecting Mari from Badan's soldiers, Auto Vajin briefly transformed and defended the two from Tiger-Roid's Tiger Bomber before reverting back to his vehicle mode. [Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai]

Behind the scenes


Auto Vajin Battle Mode's suit actor was Yoshifumi Oshikawa (押川 善文, Oshikawa Yoshifumi).


  • The name "Auto Vajin" is a portmanteau of Autobike (オートバイ) (the Japanese word for motorbike, with "v" and "b" being interchangeable letters in Japanese because of similar pronunciations), and Jin () (the Japanese suffix for person or race).
