| Jark Matter The Space Shogunate Jark Matter is an organization of aliens that have conquered an untold number of planets, including Planet Earth and the 88 constellations that surround it, with the goal of gathering Planedium, the planets' core energy, for a Planedium Bomb so they can destroy the entire universe. Their base of operations is located in the Crux System, which is protected by an invisible barrier and heavily guarded by their troops: Indavers, masked Inda battle pseudo-lifeform combatants who are armed with the Gyoisaber sabers and pilot fighter crafts called Moaider, and Tsuyoindavers, enhanced battle pseudo-lifeform combatants who lead the Indavers, are armed with the Bazookons clubs that double as a gun, and have the ability to enlarge. The high-ranking members have a Kyodainro inro as proof of authority, which can also be used to enlarge themselves. |
| Don Armage Don Armage is the deformed skull-themed leader, or Shogun, of Jark Matter who was born from the collective despair of all life in the universe. Revealing himself when Tsurugi united the universe 300 years prior, Armage established Jark Matter to destroy everything Tsurugi had built to thrive on the resulting misery, increase his power, and become a god. He was seemingly killed while battling Tsurugi, but Armage survived by possessing Tsurugi's ally Cuervo and retaliates by conquering Earth along with erasing records of Tsurugi and his comrades' achievements. Leading Jark Matter for the next 333 years, he oversaw his campaign via holograms from Planet Southern Cross in the Crux System, which he also used as a test site for his Planedium Bomb. After the Kyurangers weakened his forces and destroyed his Planedium Bomb, Don Armage confronted them on Earth, where Cuervo expelled him and forced him to take Tsurugi as his new host, Don Tsurugi, in an attempt to harness Dark Planedium energy until the Kyurangers rescue their ally. Taking on his natural form, he converts every living being in the universe besides himself and the Kyurangers into Planedium energy and absorbs them to assume a new form, but the Kyurangers are able to release them as well, defeating him in the process. In a last-ditch attempt at cheating death, Don Armage implanted a fragment of himself inside Lucky's body in the hopes of eventually resurrecting himself, but this plan backfires and the fragment is forced back into his original body before the Kyurangers permanently finish him off. Don Armage is capable of possessing others and using their abilities, producing clones, transmit his energy through his holograms, and impart fragments of his essence into others to transform them into monsters. In combat, he and his clones wield the Dark Scythe and the Houou Dark Scythe while possessing Tsurugi. |
| Cuervo Cuervo is a crow-like alien and former prisoner of Jark Matter's boot camp from Planet Verona in the Corvus System. Three centuries prior, he helped his fellow prisoners escape and was recruited by Tsurugi to become his partner and a member of the original Rebellion before joining him in recruiting 86 other warriors to overthrow Jark Matter. During what appeared to be the final battle against Don Armage, Cuervo seemingly sacrificed himself to save Tsurugi. In reality, he sold his soul to the tyrant in exchange for his life, became his host, and was reborn as Don Armage's thrall, the Hindu cosmology-themed Don Cuervo; loyally serving him from then on. While Jark Matter was commencing their final experiments on Dark Planedium on Planet Southern Cross, Cuervo revealed himself to Tsurugi when he and the Kyurangers came to destroy the Planedium Bomb. During the Kyurangers' final battle against Don Armage on Earth, Cuervo revealed he had subverted Armage's will, but willingly helped him in his plans so he could see the destroyed universe recreated as a utopia. However, Don Armage was extracted from his body and he was killed by Tsurugi. As one of the 88 legendary saviors, Cuervo wields a pair of sai and wears a heliocentrism-themed chest armor. As Don Cuervo, he wields a pair of Armaken swords. |
| Vice Shoguns The Vice Shoguns are the second-highest-ranking members of Jark Matter, serving directly under the Shogun and answering only to him. Instead of a Kyodainro, each of them carry a golden dragon pad on the right shoulder that allows them to enlarge and shrink back to normal size. They were among the organization's original members three centuries prior, having battled the original Rebellion members, and were later converted into cyborgs by Doctor Anton to prolong their lives. Following the Fuku Shoguns' defeat, Doctor Anton gathers their remains and combines them to create the three-headed Bermuda Triangle-themed Akyachuga, who wields all of original Fuku Shoguns' weapons and can perform the Vacuum Triangle attack. An enlarged Akyachuga is sent to defend Planet Southern Cross's core against the Kyurangers before being destroyed by KyurenOh (01-02-03-05-11), RyuTeiOh (07-09-10), and Gigant Houoh using the Battle Orion Ship in its cannon mode. |
| Tetchu Tetchu is a Vice Shogun from Planet Sabinain in the Cepheus System. Initially a hand-to-hand fighter in the past, his cyborg modifications armed him with the Tekkyu flail on his left arm. He is eventually defeated by the Kyurangers on Planet Toki and destroyed by Kyutamajin. |
| Akyanba Akyanba is a Vice Shogun from Planet Kyoryudo in the Cassiopeia System. She is armed with the Re-break Mic microphone, an upgraded version of the Break Mic she previously wielded in the past. Following Tetchu's death, Akyanba is sent to eliminate the Kyurangers by unlocking Naga's emotions, with the aid of Micro Tsuyoindaver. However, Naga is eventually freed from her control and leads the Kyurangers in destroying Akyanba. |
| Kukuruga Kukuruga is a Vice Shogun from Planet Quetzalco in the Perseus System. He oversaw the conquest of Planet Kaien and seemingly killed King Aslan while his son Lucky was spirited away and hidden in the Leo Minor System. In reality, he ensured Aslan's downfall and contributed to turning him into one of Don Armage's thralls. Originally armed with the Medusaber saber when Jark Matter was founded, Kukulga has his left arm outfitted with Kukulgun cannon by the present. While supporting Akyanba following Tetchu's death, Kukulga took an interest in Lucky as a result of the youth traveling back in time and defeating his past self. Kukulga later fights Shishi Red Orion on Planet Kaien, where his scheme is exposed. Upon being defeated by Shishi Red Orion and the Kyurangers, Kukulga enlarges and is destroyed by Super KyurenOh (04-06-09-11-77) and Orion Battler. |
| Gyabura Tetchu's aide from Planet Chuppa in the Capricornus System who possesses Chupacazura hair and is armed with the Chupacablance lance. After being defeated by Shishi Red and Houou Soldier, Gyabura is enlarged and killed by Kyutamajin. |
