Crisis Empire

The Crisis Empire is a fictional evil organization from television show Kamen Rider Black RX.

Bio
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.

Membership
Among the members of the Crisis Empire are:

* Grand Lord Crisis (42, 46-47): The true leader of the empire who is not seen but mentioned several times throughout the series. His voice was first heard where Gedorian eventually appeased his wrath. He is later seen in the shadows when General Jaaku begged for power. He eventually offered Black RX the chance to replace General Jaaku and become the new right hand or even rule the Earth. When refused, he summons his host body Dasmader to finish Black RX. He appears as a giant, ugly alien head in the finale after the death of his host body Dasmader. He was destroyed by RX's Revolcane. It is speculated that he is the Great Leader responsible for the formation of the previous evil organizations as he claims that it will not be his last appearance. Upon his death, his dimension got destroyed. He is voiced by Naya Goro, the same voice that was used for previous Great Leader incarnations.

* General Jaaku (, Jaaku Shogun?) (1-46): The military leader of the empire wearing a gold face mask and a black cape. He was initially leading the attacks until Crisis arrived. Towards the end of the series, he was forcefully transformed by Crisis into a stronger warrior called Jaaku Murder (, Jaaku Midola?) to kill Black RX. In the process, Jaaku Murder easily murdered the Sahara parents and dispatched V3, Riderman, X and Amazon who rescued the Sahara children from his grasp. When he was in the middle of battle, the Sahara children tried to kill him but Black RX as Roborider shielded the children and transformed into Biorider. He was inevitably killed by Black RX in a long mortal combat who used the Revolcane on him. Regressed to his normal form and near death, he proclaimed Crisis was too powerful even for Black RX.

* Colonel Maribaron (1-24, & 27-47): The sorceress of the State, a human-looking officer in black and red armor with feelings for Jaaku. She uses the yellow feather on her helmet as a weapon or to send messages. She can also use a laser whip and breathe fire. Her monsters are supernatural-based. In one event, she revived the spirits of 10 used monsters when Kotaro was believed to be dead to finish off the other riders. She also appeared to have actually cared for her fellow commanders, when she was saddened by their deaths. She was killed by Crisis when she objected on his decision to have Black RX join them.

* Naval Commander Bosgan (1-16 & 18-44): A tall man dressed in a blue-green naval coat and white tights who wields a jagged sword and dagger. He wears a white helmet with a red visor and a tiny face on his forehead, which seems to be his actual face. He is in charge of the Man-Beast/Mutant unit. He once plotted to take over General Jak but his plans were foiled when one of his swords got destroyed by General Jak himself upon discovering his treachery when he lost to Black RX twice. He died fighting Black RX when he was stabbed by the Riboclane Sword during the arrival of Granzarias.

* Captain Gatenzone (1-15, 18-25 & 27-43): A blue robotic biker in a leather jacket, slack, and one red eye on his face. In charge of Robot unit, he took to fight Black RX occasionally. He is armed with a blaster and a powerful motorcycle. He died fighting Black RX while attempting a suicide bomb attack, with only his head remaining before it was shattered by his own laser beams reflected by Black RX.

* Captain Gedorian (1-15, 18-25 & 27-42): A small, unusual creature who is in charge of Alien Lifeform unit. He is constantly hopping about and annoying everyone else. He is the most cowardly and is quick to ditch a battle before it's even over. But he soon gave his life to ensure the others avoid Crisis' wrath when he transferred his life energy into Gedoll Ridoll before his monster died at Black RX's hands.

* General Dasmader (28-30 & 33-47): An inspector sent by Grand Lord Crisis at the middle of the series. The others hate the way he does his job being arrogant and everything. He was almost killed by both General Jak and Black RX. He later leads Gatenzone and Bosgan in the attempt to kill Gedorian to appease Grand Lord Crisis' anger. He is the last surviving one and was sent to destroy Black RX after Black RX refused Grand Lord Crisis' offer. In the last episode after his death, he is revealed to be a host vessel for Grand Lord Crisis as well as a mobile body while some believe he is Grand Lord Crisis in disguise.

* Service Droid Chakrum (1, 2, 4, 5, 8, 12-15, 21, 37 & 47): A small robot that announces Jaaku's arrival before his subordinates and transmits messages from Crisis himself. He was destroyed by Kamen Rider Black RX before the final battle with Dasmader who was already possessed by Grand Lord Crisis.

* Chaps: The Crisis Empire's foot soldiers with hockey mask-like faces. They come in three colors: gray, brown and black. They later wear capes. The last of them were finished by the original 10 Kamen Riders before Black RX battles Dasmader who is already possessed by Grand Lord Crisis.

When Kotaro was ambushed and pulled underground by Ganma, Kotaro became Kamen Rider Black RX and then became Bio Rider to escape from underground then reverted to Kamen Rider Black RX and fought Ganma before retreating to where Maribaron is. After Kamen Rider Black RX thwarted Maribaron, she used Ganma on Kamen Rider Black RX.

When Shadow Beast swiped the necklace, Kamen Rider Black RX became Bio Rider and followed Shadow Beast outside. Bio Rider took back the necklace. Bio Rider called forth his Bio Blade to cut off Shadow Beast's antennaes and then kill him with it before getting Joe and Sarah out of the warehouse before the bomb planted by Gedorian blew it up.

* Ant Runt (22): A white-haired black and red ant monster that was loyal to Gedorian. He can create tornadoes and manipulate soil to bury people. He attacked a playground and its surrounding areas until Kotaro and Joe battled him. Kotaro transformed into Kamen Rider Black RX to fight Ant Runt (with Shadow Moon secretly observing the battle). When Ant Runt created a boulder, Kamen Rider Black RX became Robo Rider. Robo Rider proved useless against Ant Runt as the monster clogged all of Robo Rider's joints with dirt. Becoming Bio Rider, he easily maneuvered against Ant Runt causing the monster to retreat and everyone becoming unburied. He and Gedorian later crashed the battle between Bio Rider and Shadow Moon. Ant Runt trapped Bio Rider and Shadow Moon in an anthill. Ridron freed them and Bio Rider turned into water to attack Ant Runt. Bio Rider reverted to Black RX and destroyed Ant Runt with the Revolcane.

* Rik Back (24): A lobster-resembling monster with scythe-blades for hands and lobster legs between its upper back and shoulders. It assisted Gedorian into turning the people into vampires. When Kotaro stumbled upon one of the victims attacking people in the car, he saved one of them before Rik Back attacked. Kotaro transformed into Kamen Rider Black RX to fight Rik Back before the monster retreated. After an ambush by Chaps, Kotaro transformed into Kamen Rider Black RX and fought Rik Back and the Chaps while Joe tries to free Rik Back's hostage and fight the victims at the same time. A kick at Rik Back revealed a glowing part on it. Once Kamen Rider Black RX used his Revolcane on that part destroying Rik Back, his vampire victims were freed.

* Mat Bot (27): An anteater-resembling monster with crab-like claws. It can dig furiously underground. The Crisis Empire used it to dig into a mountain to cause a volcanic eruption until Shadow Moon took over it. When Kamen Rider Black RX encountered Mat Bot, it attacked the other Crisis Empire officers who fought back. Kamen Rider Black RX escaped the cave-in and ended up engaging Shadow Moon. Gedorian disciplined it in their base and General Jaaku told Gedorian to use Mat Bot to capture two children for revenge on Shadow Moon. After defeating Shadow Moon, Kamen Rider Black RX became Robo Rider and fought Mat Bot underground who went above ground while Robo Rider disarmed the bombs. Acrobattler tackled Mat Bot and Robo Rider used his Vortech Shooter to blast off his right arm. Robo Rider reverted to Kamen Rider Black RX and destroyed Mat Bot with the Revolcane.

* Chimera Gomera (28): An scaley ostrich/dragon-like creature that had small dragon-like heads for hands and an extra mouth on its belly. He can breathe fire from his main head, shoot electricity from the dragon-like heads, breathe steam from the extra mouth, and attack with his tail. Crisis Empire used Chimera Gomera to turn people into butterflies and infect people so they would be under their control. When it attacked a boy, Kamen Rider Black RX came to save him and battled Chimera Gomera until the victims arrived to help Chimera Gomera. Kamen Rider Black RX called for Acrobatter to tackle Chimera Gomera until he used his steam attack on Kamen Rider Black RX. General Dasmander came into view to have his fight with Kamen Rider Black RX and told Chimera Gomera to stay out of it. During battle, Chimera Gomera and his victims interfered and attacked Kamen Rider Black RX. When Kotaro followed the butterflies to their source, Chimera Gomera attacked. Kotaro transformed into Kamen Rider Black RX and fought Chimera Gomera. Kamen Rider Black RX used his RX Kick on Chimera Gomera before destroying Chimera Gomera with his Revolcane.

* Munde-gande (29): A purplish flea-like alien with a red attachable/detachable exoskeleton that it controls. He can launch the stinger from his mouth and shoot lasers from its eyes. Munde-gande was the one responsible for killing Kyouko Matoba's parents. He, Gedorian, and the Chaps were attacking a reservoir / electric power plant in hopes it can stop the flow of water in the city and Maribaron was delivering water to people. When Kotaro, Reiko, and Kyoko arrived at the reservoir / electric plant and were attacked by Munde-gande Kotaro transformed into Kamen Rider Black RX and fought Munde-gande until Gedorian and the Chaps trapped him a slime-like substance shot from their guns. Kamen Rider Black RX became Bio Rider and destroyed Munde-gande's exo-skeleton with his Bio Blade. Bio Rider reverted to Kamen Rider Black RX and destroyed Munde-gande with his Revolcane.

* Gazora-gezora (33): A brown lobster-like monster with octopus tentacles on his hips and smaller ones for hair. He can shoot lasers from his claws. He assisted Crisis Empire when it came to blowing up Setoo Bridge. When Kotaro confronted Gazora-gezora on a boat, he transformed into Kamen Rider Black RX and discovered Crisis Empire's plans during battle. As Bio Rider, he used his Bio Blade on Gazora-gezora's stomach and removed the time bomb in him and threw it into the water. Gazora-gezora went underwater and Bio Rider turned into water to follow him to land. After getting out of Gazora-gezora's trap, Bio Rider followed it and reverted to Kamen Rider Black RX. He used his RX Kick on Gazora-gezora before destroying him with the Revolcane.

* Balun Bolun (36): A one-eyed alien monster with an elephant-like trunk for a mouth. It can shoot a beam from its eye, and spew steam from its trunk. It disguised itself as a masked wrestler and brainwashed kids into rooting for him including Shigeru and his friends. When fighting his latest opponent, it turned out that Bio Rider merged with Balun Bolun's opponent and Balun Bolun sheded his disguise. As the boxer gets everyone out, Bio Rider fought Balun Bolun who made off with a boy. After turning into water and catching up to Balun Bolun, Bio Rider reverted to Kamen Rider Black RX and fought Balun Bolun. Acrobatter tackled Balun Bolun freeing the boy. Kamen Rider Black RX used his RX Kick on Balun Bolun before destroying it with his Revolcane.

* Gedoll Ridoll (42): A louse-like alien created from Bosgan that absorbs energy from machines or living things with his mouth-like hands. Gedorian sacrificed his life energy to power it up. He was destroyed by RX's Revolcane. He was the last alien monster.

Others

* Gran Zarius: The Crisis Avenger (44-45): A bird-like monster which was the Grand Lord Crisis' best soldier and worked with Bosgan when summoned by Lord Crisis. While the 10 veteran Kamen Rider team fought the Chaps, Black RX went one-on-one with Bosgan and killed him. Turning his attention to Gran Zarius, Black RX became Bio Rider and destroyed the monster from the inside out. For a time, the 10 veteran Kamen Riders thought that Black RX had been killed, but Bio Rider resurfaced and explained that he bailed out in time before destroying the Spirit World demons.

* Spirit World Demons (45): When Kamen Rider Black RX was believed to be dead after the battle against Gran Zarius, Maribaron revived the spirits of Skull Devil #1, Meta Snake, Zuno Warrior, Harmful Nimp, Harmful Mantis Gill, The Lead Burrowing Ten, Erigitron and Ant Runt to kill the other 10 Kamen Riders. Because they are dead spirits, they are all a grayish-white in color. Harmful Nimp's spirit impersonated Kamen Rider 1. All of them were destroyed by Bio Rider.
