Riotrooper

Riotroopers (ライオトルーパー) are a 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.

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
They are 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.

King's Appearance
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 Orphnoch were selected to wear the belts. They all wore black suits and, similar to Men In Black agents. 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.

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