The Auto Vajin is Kamen Rider Faiz's personal mecha. It has a limited A.I., but it is programmed to protect Mari Sonada and do as Faiz commands, in that precise order. If the person wearing the Faiz Gear attacks Mari, the Auto Vajin will attack Faiz. 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.
