SB-555V Auto Vajin

The 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).
==Description==
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.

The three riders were seemingly defeated, actually sent to the Dimensional wall.

While Takumi was on a journey, Tsukasa recruited him in a fight to protect the world against the Underground Empire Badan, which Takumi refused.
