Kurokage Troopers

The Kurokage Troopers 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 the secrets which 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 captures Baron after he is defeated by Zangetsu Shin, followed by Kota moments later after Ryoji's death.

Two Kurokage Troopers brought Kaito and Kota 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 Kota 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 lead 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 was 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 Ryouma, were stationed to protect a crack from Inves trying to reach Earth from the Helheim side. They fought the fist wave as Kota and Mitsuzane arrived. After defeating the wave, they turned their weapons to Kota when he revealed himself to them. As Kota and Ryouma 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 Inves were defeated and the crack closed, Kota steals Minato'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 Kota from going to the crack of the HQ but Ryouma tells them to let him go. Later, 12 other Kurokage Troopers who were guarding the HQ crack tried to stop Gaim but he got passed them. 3 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.

Possible Future
In a possible 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.

Like with the other Armored Riders, the Kurokage Troopers' forms are called Arms.
