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.
Users[]
While usually operating as a Rider troop, several unique individuals have also become Riotroopers at several points in the series.
Riotrooper may refer to any of the following characters:

History[]
Kamen Rider 555[]
King's Appearance[]
Kamen Rider Faiz vs Riotroopers
The Smart Buckle was created by Hanagata. There were six belts made to protect the Orphnoch King, but Hanagata said that the belts could also destroy him if they can protect him. Several Orphnochs were selected to wear the belts. They all wore black suits and glasses. Naoya Kaidō (the Snake Orphnoch) was originally appointed as leader of the Riotroopers until he found out that Yuji Kiba, the person who gave him the Smart Buckle, was planning to attack Mari and the gang, as well as attempt to kidnap Teruo Suzuki to get the Orphnoch King inside the boy to fully awaken and take over their body while the boy died. This made Kaidō quit being a Riotrooper as he felt Yuji lost his belief in protecting humanity Kaido, with the help of Mihara.
Masato, Dying A Glorious Death[]
After a fight with a Riotrooper despite Masato's disease, he confronts Kiba that he will fight the Orphnoch King. Mari talks briefly with Rina before she gets kidnapped, once again to lure Kusaka. Hanagata dies from his rapid evolution. As Kusaka Masato confronts Kiba that he joined Smart Brain, Takumi, Kaido, and Mihara kills all Riotroopers as Faiz Axel Form, Snake Orphnoch, and Delta respectively.

Lost World[]

Kaixa vs Riotroopers
A bunch of Riotroopers show up and start attacking people. Kusaka as Kamen Rider Kaixa defeats them on his own.

Delta facing Riotrooper V2.
Mihara as Kamen Rider Delta meets up with Kusaka and Mari, and one more Riotrooper shows up. It seems to be different from the others (Riotrooper ver. 2), and is equipped with the Faiz Edge. Kaixa and Delta fight it and its helmet is damaged and reveals that inside is the Rose Orphenoch. Kusaka thinking that it was Mihara who sent Mari the roses.
With Kaixa and Delta can’t stand up to the Riotrooper v2, they run away with Mari. But then Kusaka grabs Mihara and tosses him back at Murakami, saying that he deserves it for daring to send roses to his beloved woman. Mihara screams that it’s a misunderstanding, and for Kusaka to help him, but Kusaka just sneers and a blue petal lands on his outstretched hand, turning him to ash.
Takumi arrives on the scene and runs into Murakami, now in Rose Orphenoch form as the Riotrooper v2 was badly damaged.
Paradise Lost[]
The Smart Buckles are mass produced (approximately 10,000). These wearers were more akin to traditional military unit. Their purpose is to exterminate any human resistance that oppose the Orphnoch race, including the Human Liberation Army. Led by Kamen Rider Psyga, they attacked the human sanctuary until Yuji, Yuka, and Naoya intervened. They were then sent to hunt Mari and Takumi, where Takumi regained his memory as Faiz, then transformed to protect Mari from them. When they are knocked out of their Riotrooper forms, they transform back to their Orphnoch forms.

Notes[]
- The Riotroopers are the first evil mass-produced Kamen Rider to appear in the Heisei Era.
- In the S.I.C. Hero Saga Kamen Rider 555: Lost World (the prequel of the movie Paradise Lost), an upgraded version was used by Kyouji Murakami which was called Riotrooper ver. 2.

Smart Buckle in Kamen Rider Decade
- In the episode 11 of Kamen Rider Decade, the Smart Buckle appears with the Delta Driver and Psyga Driver in the ruins of Smart Brain High School.
- In the English version of Kamen Rider Climax Scramble. Riotrooper is named Lion Trooper instead. This translation version is ironically not a suitable one as Riotrooper has no lion related on the rider suit and the name itself.
- However in Paradise Lost movie, one of the Riotrooper's Orphnoch form is a Lion Orphnoch.
