The Crisis Empire (クライシス帝国 Kuraishisu Teikoku) is a fictional evil organization from television show Kamen Rider BLACK RX.
The Crisis Empire are group of aliens who attempt to invade Earth. They always attempt to justify their invasion and their plans to exterminate the human race. They also claimed that their home planet is being sucked into a black hole. Since they think that humans do not really care about the Earth, the Crisis Empire thinks it is right for them to take over Earth.
World of Black RX
The Crisis Empire also exists in the A.R. World of Black RX, where it is fought by a alternate Kamen Rider Black RX. This Crisis Empire also possess an army of Chap foot soldiers. Having already recruited the Gorgom cult from the World of Black,Dai-Shocker's Apollo Geist arrived in this world summoning Gorgom's Sai Mutant to convince Strange Demon Robot Schwarian, who sees himself as the ultimate machine in his branch, to join Dai-Shocker. He originally turned down Apollo Geist's offer to join Dai-Shocker until he sees his power first hand. Black RX teamed up up with the A.R. Kamen Rider Black from the World of Black, helping Decade and his friends stop Dai-Shocker. Schwarian was destroyed by Decade Complete Form with the aid of Agito Shining Form as Apollo Geist fled to another A.R. World.
General Jark of the Crisis Empire served as one of Dai-Shocker's commanders as the organization, based in the World of Decade, began its invasion of the A.R. Worlds. Jark led a Dai-Shocker platoon pursuing Diend and Natsumi Hikari as Decade arrived, intent on fighting Dai-Shocker and saving his friends, Jark was then killed by Diend.
Jark reappeared as part of the new Dai-Shocker assembled by Tsukasa to wipe out the Super Sentai, ensuring the survival of the Kamen Riders. After Dai-Shocker's alliance with Dai-Zangyack is revealed, Jark is once again defeated along with Shadow Moon by the combined forces of Kamen Rider Black and the Hikari Sentai Maskman.
In an alternate timeline caused by Ankh leaving a O-Medal behind in the year 1971, Shocker achieved its goal of dominion of Japan with the Shocker Greeed. Crisis Empire, represented by General Jark, was among the various organizations that forms a partnership with Shocker.

This is the unit led by Captain Gedorian:
- Culculten (6): Three toad-like mutants whose eggs were launched into a river, a fountain by the Crisis Empire. They can spew foam from their mouth that induce fevers. Shigeru encountered one of the Culculten eggs which hatched and that Culculten befriended him. The other two hatched and joined their fellow Culculten in Shigeru's room later that night in hopes of abducting him and attacking his family. Shigeru broke free when he shoved an ice cube into the one that was holding him causing them to retreat since they hate the cold. When encountered again, Kohtaro used the sun to break free and transformed into Kamen Rider Black RX and they wrestled with him. Each one was destroyed by RX's Revolcane and the effects of their foam wore off. Were used for "Cogwarts" in Mighty Morphin Power Rangers.
- Atchpetchy (9): A cactus-like monster with jaw-like pincers. He can emit a vine from its mouth, bite, launch its pincers, and regenerate its pincers.

He turned into a cactus and escaped. When Atchpetchy disguised itself as a cactus to entice a girl, Kohtaro appeared and the Skullmastars helped to buy Atchpetchy some time to get away. When Kamen Rider Black RX found the location where Maribaron and Gedorian had her, he used Ridron to enter and a battle engaged between him, Gedorian, and Atchpetchy as Ridron gets the girl to safety. When he got caught on Atchpetchy's vine, he called for Acrobatter and broke free from his vine. While riding on Acrobatter, Kamen Rider Black RX destroyed Atchpetchy with his Revolcane.

When he was first encountered by Shigeru, he made an intelligent clone of him from his slime. He later made clones of Shigeru's friends and later Reiko. Kohtaro transforming into Kamen Rider Black RX and the clones dissolved. Kamen Rider Black RX used his Revolcane to break the slime around Reiko, Shigeru, and Co's prison and then destroyed Dogmalogma with it. Was used for "Slimeasect" in Saban's Masked Rider.
- Flarmiglarmi (13): A jellyfish-like parasite monster with lots of tentacles which it attacks with. He can also teleport.

Kohtaro saved the father from the Chaps and henshined into Kamen Rider Black RX to fight Flarmiglarmi and retreated after one kick. When he disguised itself as a girl to obtain it from Shigeru and his friends who found the jewel, he captured them until Kohtaro came to their rescue. Flarmiglarmi threw the jewel to a Chap who used it to power a laser. Kohtaro transformed into Kamen Rider Black RX. When Kamen Rider Black RX got caught in Flarmiglarmi's tentacles, he called for Acrobatter.

When Bang-Gong swiped the necklace, Kamen Rider Black RX became Bio Rider and followed Bang-Gong outside. Bio Rider took back the necklace.
