Kamen Rider Faiz comes from Kamen Rider 555, the Japanese live-action tokusatsu series that aired in 2003, in which Takumi Inui transforms using the Faiz Driver system developed by the fictional Smart Brain corporation. The henshin sequence became one of the show's most recognisable moments, with its futuristic phone-based gear setting it apart from earlier Rider series. Fans later clipped and shared the transformation audio on soundboards and in video edits, keeping it popular with tokusatsu audiences long after the series ended.
