SB-555V Auto Vajin

Designated "SB-555V", the Auto Vajin is a transforming, artificially intelligent support mecha for Kamen Rider Phi seen in the fanfictional television series Kamen Rider 555. It is the first of the support mecha seen in the series, that transforms from a Smart Brain motorcycle (Vehicle Mode), into a flight capable robot (Battle Mode).

Auto Vajin
The Auto Vajin is Kamen Rider Phi's personal mecha. It has a limited A.I., but it is programmed to protect Maria Jardine & do as Phi commands (in that order). If the person wearing the Phi Gear attacks Maria, the Auto Vajin will attack Phi.

Initially it is fairly incompetent in its duties, accidentally shooting Phi on a few occasions, but it became a valuable asset later in the series, often putting itself in harms way to protect various characters, & coming to the rescue when Phi is in great danger. The Auto Vajin also carries the Phi 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, rebuilt, & destroyed again by the Elasmotherium Orphnoch at the end of the series.
