Also known as: 仮面ライダーファイズ
Lead Rider of Kamen Rider 555, thirteenth show of the Kamen Rider series and fourth of the Heisei generation.
Inui Takumi is a lone wolf who was made the reluctant protector of a suitcase containing the Faiz Gear, using its contents to become Faiz and eliminate Orphnochs, monsters who feed on humans and are said to be humanity's next evolutionary step.
Faiz has a black color scheme with red "photon blood" vessels running across the suit. His design is inspired by a shark and the Greek letter Φ.
He can change into two advanced forms: the speed-oriented Axel Form, and the power-oriented Blaster Form.
Just like other Rider Gears in its eponymous show, the Faiz Gear has multiple wearers, but the primary one is Inui Takumi himself.
