Kurokage Troopers

The Kurokage Troopers (黒影[クロカゲ]トルーパー) are an unknown group of Armored Riders that are the exact copy of Ryoji Hase's Kurokage suit, with the exception of the Rider Indicator and a silver belt strap as opposed to a yellow one. They are employed by the Yggdrasill Corporation.

History
Via the data of Ryoji Hase as Kurokage, these Rider troops appear where their mission is to silence everyone to the secrets which are hidden beyond Yggdrasill by destroying the lingering evidence of the Helheim forest. Later, in a holographic room, Kurokage Troopers were used to help Zangetsu Shin test his new power. The Kurokage Troopers appeared again and capture Baron after he is defeated by Zangetsu Shin, followed by Kouta moments later after Ryoji's death.

Two Kurokage Troopers brought Kaito and Kouta to Yggdrasill's headquarters, later taking them to a cell. When the two were freed by Mitsuzane, six Kurokage Troopers came to apprehend the trio. After a brief scuffle, Kaito transformed into Baron to fight them as Kouta and Mitsuzane ran off in different directions. Mitsuzane was soon after met by three Kurokage Troopers on Dandeliners, transforming into Ryugen to face them.

While Gaim and Baron escaped, about three Kurokage Troopers chase them in the forest before being defeated by the duo.

When informed by Takatora that Gaim and Baron will plan a raid on Yggdrasill's lab, the Kurokage Troopers led by Sid overpowers Gaim and Baron via Tulip Hoppers. However, when Gaim and Baron planned on a second attack, he uses his own Tulip Hopper and Baron uses two Dandeliners to defeat the Kurokage Troopers and destroy their Tulip Hoppers. Later two Kurokage Troopers that was protecting the crack that leads to Yggdrasill Tower were defeated by Kaito.

Meanwhile three Kurokage Troopers helped Ryugen fight two Elementary Inves in a tunnel. After the Inves were defeated and the crack closed up, two of the Kurokage Troopers burned the Helheim plants that came from the crack.

Sometime later, 12 Kurokage Troopers, supervised by Marika and Ryoma, were stationed to protect a crack from Inves trying to reach Earth from the Helheim side. They fought the first wave as Kouta and Mitsuzane arrived. After defeating the wave, they turned their weapons to Kouta when he revealed himself to them. As Kouta and Ryoma were talking, a second wave of Inves attacked and they fought and defeated them. A third wave came, now with the assistance of Gaim, fought them. After the Inves were defeated and the crack closed, Kouta steals Yoko's Peach Energy Lockseed, 3 tried to stop him from getting away but were unsuccessful. The rest of the Kurokage Troopers try to go after Kouta from going to the crack of the HQ but Ryoma tells them to let him go. Later, 12 other Kurokage Troopers who were guarding the HQ crack tried to stop Gaim but he got past them. Three of the Kurokage Troopers who were in the base tried to fight Gaim but were defeated by him. Later, as Gaim goes through the hallway to destroy the Scalar System control room, two Kurokage Troopers tried to stop him but were also defeated followed by another two.

When Gaim landed on top of Yggdrasill Tower in his new Kachidoki Arms, ready to destroy the Scalar System, a group of dozens of Kurokage Troopers on Dandeliners came to stop him. They began bombarding him with gunfire from a distance but were unable to pierce his extremely powerful armor. Pulling out Kachidoki Arms' weapon, the DJ Gun, Gaim fought back against the Kurokage Troopers who tried to encircle him but were all taken down with their Dandeliners destroyed. A remaining group of Kurokage Troopers came up on the roof and tried to fight him but were quickly blown away by his battle flags.

A group of Kurokage Troopers were guarding the research camp by the crack in the Helheim Forest when they were attacked by a horde of Elementary Inves led by the Overlord Demushu. Fortunately, Overseer Kureshima was nearby and fought back the Inves with them as Zangetsu Shin, the Kurokage Troopers were later aided by Armored Rider Bravo as Gaim and Zangetsu Shin fought against Demushu.

A group of Kurokage Troopers as well as four Suika Arms units were used to test the power of the android body Hakaider, which Ryoma Sengoku had transplanted his brain into. They were easily defeated by Ryoma, who had grown an urge to destroy as Hakaider. Fortunately for the fallen Kurokage Troopers, Marika intervened and stopped the test.

When Demushu arrived in Zawame City and started attacking, Ryoma sent out the Kurokage Troopers on their Dandeliners to capture the Overlord Inves. Led by Marika, they interrupted the battle between Demushu and Gaim (Kachidoki Arms) and then attacked Gaim under orders from Ryoma to take him out so he didn't defeat the Overlord. Demushu blew away the Kurokage Troopers so he could take down Gaim himself, knocking him out of his transformation before being attacked by Baron, who rescued Kouta. With Baron escaping, Demushu attacked Marika and the Kurokage Troopers, Ryoma then told his forces to ignore them and focus on capturing the Overlord. With the troopers on the ground using a refractive smokescreen to blind Demushu, the Dandeliners moved in and started their assault. However, the smoke soon cleared and Demushu was able to defend himself against the Dandeliner attack. Ordered by Ryoma to capture the Overlord at all costs never mind a few casualties, Marika and the infantry stood their ground against Demushu before assistance arrived in the form of Kaito and Zack who transformed into Baron Lemon Energy and Knuckle.

"Yggdrasill's done for!"

- The Kurokage Troopers flee in the face of full-scale Inves invasion of Zawame.

With Baron and Knuckle fighting back the Overlord, Ryoma used this opportunity to send in three Dandeliner units to launch a fly-by aerial strike. However, this only suceeded in getting the Riders off Demushu, allowing him to blast back and escape. With Yggdrasill no longer able to conceal their activities from the public, the Kurokage Troopers made patrols around Zawame to find Demushu while incinerating any Elementary Inves that they encountered. However, the situation took a turn for the worse when another Overlord, Redyue, arrived through the crack in Yggdrasill's HQ leading a massive army of Inves. With the Yggdrasill Tower completely infested inside and outside with Helheim flora, Ryoma deserting Yggdrasill, and Zawame facing a full-scale invasion of Inves, the remaining Kurokage Troopers fled, leaving Yoko to side with the Beat Riders.

Presumably the Kurokage Troopers were disbanded following the evacuation of Zawame City and subsequent outlawing of the Yggdrasill Corporation as a terrorist organization. Takatora later reveals the Kurokage Troopers had been completely decommissioned and their Drivers disposed of as a precautionary measure, save for one Driver and Matsubokkuri Lockseed kept as a precautionary measure, which would be taken by Hideyasu Jonouchi to battle Kamen Rider Jam and the Grasshopper Monster.

Potential future
In a potential future, several Armored Riders who were presumably Kurokage Troopers appeared in Suika Arms among the Inves armies of Baron as well as Zangetsu and Ryugen in the Sengoku Rider War. Baron's Suika Arms Riders were in Gyro Mode as his army engaged Gaim and his army of Inves, while the Suika Arms Riders in Zangetsu and Ryugen's army, which stood neutral and observed, were in Yoroi Mode.

Arms
Like with the other Armored Riders, the Kurokage Troopers' forms are called Arms (アームズ).
