Riotroopers (ライオトルーパー, Raiotorūpā) were paramilitary force of henchmen from the Kamen Rider Series installment Kamen Rider 555 and the accompanying film Kamen Rider 555: Paradise Lost. They are the first set of "Rider-like" foot soldiers within the franchise. They are also the first case of a Rider originally created for a Kamen Rider movie that was later introduced in the TV series.
They were employed by Smart Brain and are a personal army that fought against the title character Kamen Rider Faiz and his allies. As the show uses the Greek alphabet as a motif, omicron (O) is their Greek symbol, and unlike the other Rider Gears, they seem to possess no Smart Brain number, most likely due to the lack of a phone unit in the Gear. Their data is derived from the Faiz Gear with some modifications for mass production purposes, which results in the suits' resemblance to a simplified Faiz. Both sets of troopers, in the series and in the movie, were destroyed by Faiz in Axel Form. In the TV Series, they were destroyed by Faiz Axel's Axel Sparkle Cut; and in the "Paradise Lost" movie, they were destroyed by the Axel Crimson Smash.
