Category:Negative Syndicates

"Negative Syndicates" is the official operations term used by SGS in reference to Precious-hunting villain factions. As such they oft find themselves at odds with SGS' team, the Boukengers.

Gordom Civilization
The Gōdom Civilization (ゴードム文明, Gōdomu Bunmei?) is a mysterious civilization that once ruled the sea 40,000 years ago and worshiped the Destruction God Gōdom (Hakushin Gōdomu) that came from outer space. With the Organs (the Heart and Brain) of Gōdom (both Precious relics) as their underwater power source, Gōdom ruled the world as "gods" themselves until they were sealed at the bottom of the ocean by those who feared their power. However, it was due to Masumi and Natsuki that the seal was broken and its sole survivor, Gajah, was released from suspended animation. The Gōdom Civilization, in addition to wielding mystic powers, also has technological know-how in creating the Gōdom Engine.

Gajah
High Priest Gajah (大神官ガジャ, Daishinkan Gaja?) The last surviving member of Gordom.

Jaryuu Tribe
The Jaryuu Clan (ジャリュウ一族, Jaryū Ichizoku?, 2-47, 49) are a race of Reptilian humanoids, the result of genetic manipulation of dinosaur DNA. But their true origins are tied to the ancient civilization of Lemuria, which is said to be the very first civilization to exist in an unknown ancient continent and had mastered genetic research. They are bent on reverting the Earth to the age of the dinosaurs, exterminating all of humanity, and ruling the world with the power that the "Precious" provides, They believe they are the true heirs of the Earth because of their dinosaur gems. However, according to Souta, they aren't very smart. A Jaryuu can go for eternity without water. Their name translates into "Evil Dragon."

Ryuuwon

 * Creator King Ryuuwon (創造王リュウオーン, Sōzōō Ryūōn?, 2-47) is the Chief and creator of the Jaryuu and rivals with Bouken Red. As revealed by professor Igarashi in Task 29, Ryuuwon was originally a human who lived two centuries ago. A scholar obsessed in creating a world for dragons, he became a treasure hunter and made it his goal to obtain the Lemurian Precious, the "Mythical Beast", destroying many important Lemurian ruins until he was left on a deserted island. He experimented on himself using the genetic research of Lemuria and its treasure, the Helmet of Ryuuwon, to assume his current state with immortal life and a miraculous healing factor called,the "Jaryuu Soul Transmission", which allows him to evade mortal injury with his regenerative abilities. He wields two swords as well as a gun that can also enlarge his minions. He and Gajah don't get along, because they both share a common enemy in the Boukengers, they sometimes work together, usually because of of Gajah's cunning. One such team up with Gajah was to find the Precious Manuscript of Leon Giordana, which resulted in defeat, but Gajah used the information he obtained without Ryuuwon realizing it until it was too late. In task 29, Ryuuwon reveals his special sword's move: His sword shines with green and black flames and at the call of "the power of my dream!", Ryuuwon delivers a double horizontal cut.

He was last defeated by Satoru's Golden Slash attack, but he returned in Task 33, gaining help from Gai and Rei to capture Natsuki and gain control of the Precious Sun of Lemuria to power Grand. He was tricked in returning the favor to the Questers by getting the Philosopher's Herb for them. In Task 47, Ryuuwon discovers, after failing to create more Jaryuu Soldiers, that his body had reached its limit, and searches for a Precious to regain full-power no matter what. When he reaches the shrine in which Pandora's Key is hidden, Gajah attacks him and steals the Key. When the Boukengers question him, Ryuuwon tells Satoru that as himself, all adventurers seek power and in the end, die a terrible fate, as seen with Ryuuwon apparently committing suicide, leaving his helmet behind. Makino recovers the helmet, as it turns out to be a precious. However, once at the Precious Bank, Ryuuwon regenerates from the helmet, knocks out Makino and tries to steal the Egg of Lemuria to duplicate Gajah's modification on it by using himself to become a new lifeform to erase his humanity. Satoru confronts Ryuuwon, who fought BoukenRed with the Soldier's Crossbow, the Jabou & the Seiryuutou. In the end, Ryuuwon reverted to human form and ran back into the Precious Bank to get the egg with Satoru in pursuit. Despite realizing his dream "to no longer be human" made him human, Ryuuwon was bent on getting the Lemurian Egg as the Precious Bank explodes with him and Satoru inside. Although Ryuuwon was killed, the Jaryuu that survived are intent on fulfilling his goal of a world without humans. He is based on Kyōryū Sentai Zyuranger's DaiZyujin.

Ryuuwon is voiced by Junpei Morita (森田 順平, Morita Junpei?), who also portrays his human form.

The Jaryuu

 * Dragonoid Soldier Jaryuu (竜人兵ジャリュウ, Ryūjinhei Jaryū?, 2-49): The dragon-like warriors created by Ryuuwon using his own blood and machinery. They wield swords and can summon hundreds of poisonous red lizards from their bodies. They are fewer in number when compared to the Karths, but more powerful. They are also capable of speech. Three piloted Dold before its destruction and all perished along with Dold. In Task 21, with Uchide's Mallet, Ryuuwon made three of them grow to giant size. When the Boukengers formed Ultimate DaiBouken, he made them grow again, making them even twice the size of DaiBouken. However, Eiji reclaimed the Mallet for himself, and made Ultimate DaiBouken grow in size to even the odds. Ultimate DaiBouken's Ultimate Blaster finished two of the Jaryuu, and SirenBuilder, still normal size, jumped down the third's throat and finished it off from the inside. In Task 25, three Jaryuu made suggestions to Ryuuwon for their kind's benefits after eating the Fruit of Knowledge. In the end, all but one of the Jaryuu were killed off in the ritual to create the last Wicked Dragon, or so it seemed. At the end of the final episode, two Jaryuu are seen battling Dark Shadow and the Boukengers for the Ru-Yi-Bang Precious. Though their leader is gone, they are intent on carrying out his wishes. They are based on Kyōryū Sentai Zyuranger's Dragon Caesar.

The various Jaryuu are voiced by Tamotsu Nishiwaki (西脇 保, Nishiwaki Tamotsu?).

Wicked Dragons
Wicked Dragons (邪悪竜, Jaakuryū?) These are the Jaryuu Clan's human-sized monsters. They are created when Jaryuu battle each other in a ritual fight to the death. Once only one survivor remains, Ryuuwon awards him by transforming the surviving Jaryuu into a stronger Wicked Dragon by impailing him with one of his swords and transferring his power with the push of a button on the sword. The "instructions to create a Dragon Man", written by Ryuuwon himself 200 years ago based on his Lemurian research, came to the hands of a writer, who took those notes as inspiration for a novel Satoru read and created confusion as it was the first time Boukenger faced a Wicked Dragon. There have been special cases in which they are enlarged but the cause is always different. As seen in Task 16, Ryuuwon can make a Wicked Dragon grow by firing a special dart from his gun.


 * Wicked Dragon Dryken (邪悪竜ドライケン, Jaakuryū Doraiken?, 7, 24): Ryuuwon sent this first Wicked Dragon to find the Scale of the Salamander. Ryuuwon attempted to transform Dryken into an all-powerful giant dragon by using the Scale of the Salamander and by increasing the temperature of the factory that they were in to two thousand degrees, which set the building aflame, but DaiBouken Mixer used the Wall Shoot technique to contain the explosion in Hyper Concrete. But it turned out the Salamander’s Scale was taken out of the building before the explosion. Dryken himself ultimately fell victim to the Scale's power when Satoru used it to activate the AccelTector for the first time and used the Dual Crusher Mixer Head to encase Dryken in Hyper Concrete and used the Drill Head to drill him into oblivion. He is based on Seijuu Sentai Gingaman's Gingaioh.
 * Wicked Dragon Lindom (邪悪竜リンドム, Jaakuryū Rindomu?, 13): Ryuuwon sent/dispatched to find the Angel's Raiment of the Moon and the Medicine of Immortality—the Treasures of Princess Kaguya. He was defeated by the Dual Crusher (used by BoukenBlue), but grew giant when he fell into the Medicine. From then, he was terminated by Super DaiBouken after giving a thrashing to normal DaiBouken. He is based on Kyōryū Sentai Zyuranger's Goryuujin.
 * Wicked Dragon Naga (邪悪竜ナーガ, Jākuryū Nāga?, 15-16): This one was dispatched with Ragi by Ryuuwon to attack the Boukengers and to find the Aqua Crystal, and his onslaught has become personal as Satoru took Ragi under his protection, since Ryuuwon ordered him to dispose of Ragi after he failed to obtain the Crystal Document. He was defeated by the Dual Crusher Drill Head (wielded by BoukenBlack) only to be the first to be made giant by Ryuuwon, and terminated by Ultimate DaiBouken after giving Super DaiBouken a thrashing. It is based on Seijuu Sentai Gingaman's Combined Beast Warrior Bull Taurus.
 * Wicked Dragon Talong (邪悪竜ターロン, Jaakuryū Tāron?, 27): A Chinese dragon that specializes in feng shui-based strategies. With Ryuuwon, Talong intended to resurrect the "Ground Dragon," located where a Ryuketsu, a concentration of Chimeku energy produced by feng shui in the ground, found by using the "Dragon's Eye," to create a Ryuketsu. With this Precious, Talong gave Satoru the worst luck, putting him in even mortal danger. However, thanks to the support of his teammates, Satoru overcame his bad luck and fought Talong, who, defeated, falls into the Ryuketsu, absorbing the Earth Dragon's power to become gigantic. The Boukengers fight him with DaiBouken but have a hard time, until Sakura launches machines 6, 7, 8 and 9 and strategically places them with feng shui against Talong, and with the help of the recovered "Dragon's Eye" gave him bad luck in battle, allowing them to finally destroy him. It is based on Gosei Sentai Dairanger's Daijinryuu.
 * Wicked Dragon Dembey (邪悪竜デンベエ, Jaakuryū Denbee?, 37): Dembey was created to infiltrate MOE-TV to obtain "The Ring of Prosperity" posing as the station's mascot "Dembey", when Sakura foils its plans, reveals his true, violent identity and along with some Jaryuus, enlarges itself and attacks with his firebreath and sword but was killed by Voyager DaiBouken's Riding Adventure Drive. The way to difference him from the real Dembey is that the evil one isn't wearing shoes. He is based on Bakuryū Sentai Abaranger's AbarenOh.
 * Wicked Dragon Tagargin (邪悪竜ダガーギン, Jaakuryū Tagāgin?, 45): The strongest Wicked Dragon Ryuuwon has created by making his whole Jaryuu horde (about 3000) kill each other, making it also the last of the Wicked Dragons. He overuses the word "baby." His mission is to aid Ryuuwon in finding "The Three Headed Dragon of Darkness", a precious that gives the one it chooses, great power. He can absorb an attack and reproduce it with double power with his mutating right arm. However, as his right arm consumes much energy when transforming, he can be attacked provoking a general paralysis. Targagin knows this weak point of his and knew when the Boukengers tried to use it, they were delivering weak attacks on purpose so the counter could be re-countered when wearing the Accel Tector, but he revealed that his weakness wasn't as easy to exploit as they expected (Masumi failing to do so and Satoru was nearly killed before succeeding). Enlarges himself as a last resort but is destroyed by Siren Builder Crane and Zuban. It is based on Bakuryū Sentai Abaranger's MaxOhJa.

Great Evil Dragons
Great Evil Dragons (大邪竜, Daijaryū?) are the Jaryuu Clan's giant monsters: cybernetic, genetically altered dinosaurs which must be piloted from within. They have the kind of steering wheel that one would find in a nautical ship and the cockpit of most Great Evil Dragons is also a throne room for Ryuuwon.


 * Great Evil Dragon Dold (大邪竜ドルド, Daijaryū Dorudo?, 1-2): In the first two Tasks, Dold swallowed Gajah after the Gōdom God was destroyed. It was created by Ryuuwon and manned by three Jaryuu. When Dold was defeated by DaiBouken's Adventure Drive, Ryuuwon activated a bomb on Dold to blow up DaiBouken and kill the Boukengers, but the team kicked Dold away before he blew up, taking all three Jaryuu with him. It is based on Kyōryū Sentai Zyuranger's Beast Knight God King Brachion/Super Beast Tank King Tanker.
 * Great Evil Dragon Zard (大邪竜ザルド, Daijaryū Zarudo?, 10-11): Ryuuwon was onboard Zard twice. It has immense strength and can firing Gatling gun blasts and chains that can wrap around the enemy. The first time, where he simply rode and Zard was piloted by a Jaryuu, he and Gajah defeated DaiBouken. The second time, Ryuuwon personally piloted Zard himself, but Zard was terminated by Super DaiBouken, nearly taking Ryuuwon with it. Zard's name is a pun on Lizard. It is based on Seijuu Sentai Gingaman's GigaRhinos.
 * Great Evil Dragon Girad (大邪竜ギラド, Daijaryū Girado?, 10-11): Girad is an incredibly agile dragon that wields a boomerang. The first time that this speed type dragon appeared, it was manned by three Jaryuu, and both Zard and Girad managed to defeat DaiBouken. The second time in Task 11, Gajah personally piloted Girad. However, Super DaiBouken "Wall Shot" Girad's feet to the ground with Hyper Concrete (in order to squander Gajah's ambush attempt, the steering wheel was immobilized as a consequence) and terminated Girad himself, almost claiming Gajah's life. It is based on Seijuu Sentai Gingaman's GigaPhoenix.
 * Great Evil Dragon Zorad (大邪竜ゾラド, Daijaryū Zorado?, 16, 33): Zorads are pterosaur-like Great Evil Dragons created by Ryuuwon for aerial combat. The cabin has room for just one Jaryuu: the pilot. Three of them were involved in the GoGo Jet's first dogfight and were soundly destroyed; Satoru even used the sun to blind the pilots of the remaining two. Their name is a pun on "sora" (空), the Japanese word for "sky". They are based on Bakuryū Sentai Abaranger's Top Galer.
 * Evil Mechanic Dragon Grand (邪機竜グランド, Jakiryū Gurando?, 33-34): A new type of Great Evil Dragon created by combining Ryuuwon's best genetic modification technology and the Questers' Gōdom Engine technology, Grand is the ultimate cyborg battleship. Armed with laser cannons, can build temporary barriers and capable of unleashing unlimited number of Zorads. Its "Grand Blaster" can neutralize Ultimate DaiBouken's Ultimate Blaster. All these features make the Gōdom Engine insufficient to mobilize it, being "The Sun of Lemuria" the only energy source powerful enough to make it fully operational. In a first attack, Grand's tremendous power made Ultimate Daibouken disassemble. However, after GogoVoyager appears and destroys the entire fleet of Zorads, the energy given by "The Sun of Lemuria" ran off and had to retreat. After recharging in Task 34, Grand attacks again but is greatly overpowered by the just formed DaiVoyager and destroyed with the Adventure Double Screw. It is based on Mirai Sentai Timeranger's V-Rex.

Dark Shadow
Dark Shadow (ダークシャドウ, Dāku Shadō?, 3-49, Gekiranger vs. Boukenger) is a stealth assassin-group descended from the ninja order called the Society of Shadow (シャドウの結社, Shadō no Kessha?). They are experts in espionage that work to obtain the Precious for the highest bidder. Dark Shadow has no footsoldiers of its own, but Yaiba and Shizuka do utilize the Karths on several occasions.

Gekkou
Gekkou of Illusions (幻のゲッコウ, Maboroshi no Gekkō?, 3-49): The wise owl-like leader of Dark Shadow

Yaiba
Yaiba of Darkness (闇のヤイバ, Yami no Yaiba?, 3-46): Nicknamed "The Paper Crane Ninja", he believes that darkness is the superior force in existence. This armored warrior uses two ninja swords that can be combined into a double bladed naginata.

Shizuka
Shizuka of the Wind (風のシズカ, Kaze no Shizuka?, 3-49, Gekiranger vs. Boukenger): A mistress of disguise and a kunoichi of wind who fights with a pair of kunai.

Ashu Tribe/Questers
The Ashu Tribe (アシュ族, Ashu Zoku?, 17-42) was apparently an unknown branch along the human evolution line. Each Ashu has a concentration of life force, namely a "soul", which gives it particular fighting abilities. Feared and hunted down as "youkai" (demons) in ancient times due to their feline-gargoyle appearance, they were ultimately sealed within another dimension using the "100-Demon Mirror", only Gai and Hyouga remaining free. According to Mr. Voice, humans seeing the Ashu is what inspired the various monsters in myths. They first appeared in Task 17 to obtain the mirror to release their brethren. However, only Rei was freed before the mirror was shattered to keep the others from entering the human world. Eiji Takaoka, as a member of the Takaoka clan, has been fighting this group even before joining the SGS. After their first defeat at hands of the Boukengers, Gajah uses his power to bind Gai's and Rei's souls to the world long enough to install his Gōdom Engines into them. With the Gōdom Engines in them, Gai & Rei formed new bodies for themselves and became Questers (クエスター, Kuesutā?, 19-42), robotic-armored versions of themselves. The Questers possessed the ability to create wavelengths with the Gōdom Engine, which interfere with the power of the AccelSuits' and GoGo Vehicles' Parallel Engine, and can melt into the ground. The two soon left Gajah and became freelance Treasure hunters, using the Gōdom Engine technology and the Precious for their benefit of eliminating the human race, making the Questers the most dangerous of the Negatives. In Task 42, after the Homunculus was destroyed, the Questers challenged the Boukengers to battle, with Gai being defeated by Eiji, while Rei was destroyed by the Dual Crusher, finally destroying the remaining Ashu Tribe on Earth. Eiji would later set up gravemarkers for the Questers out of respect.

Gai
Furious Fiend Gai (怒りの鬼神ガイ, Ikari no Kishin Gai?, 17-19): The leader of the eastern Ashu Tribe, he is a purple and green demon who can conjure forth a bazooka-like weapon. Gai is a brash and savage demon who loves to destroy, laughing at the sight of others suffering. He and BoukenSilver are bitter enemies, because long ago he told a young Eiji that he was part Ashu and that his mother was one as well and because he killed Eiji's father, Kando, when he tried to prevent Eiji's Ashu side from growing. When Gai saw Natsuki's bracelet he said it was "The Proof of the Chosen One," and he and Hyouga kidnapped Natsuki and used her blood to free Rei from the 100-Demon Mirror. He used Rei's illusion-inducing powers to pose as Satoru's old companion Masaki to confuse and kill him with the Fighter's Crossbow, however when Satoru confronted his illusion it disappeared. Though defeated by Eiji (who threw his monk staff at him like a javelin), and terminated by Ultimate DaiBouken and the Ashu Spirit Extinguishing, Gajah resurrected him as Quester Gai (クエスター・ガイ, Kuesutā Gai?, 19-42). In this form Gai wields two guns that also turn into short swords. But in either form, Gai was still Eiji's mortal enemy. He was finally defeated after Homunculus was destroyed in a final battle with Eiji in Task 42. While his Ashu form was based on Gosei Sentai Dairanger's Ryuusei'Oh, his Quester form is modeled after Dairen'Oh.

Gai is voiced by Kenta Miyake (三宅 健太, Miyake Kenta?).

Rei
Grand Beast Rei (大いなる獣レイ, Oinaru Kemono Rei?, 17-19): Rei is the most evil of the Ashu. Gai and Hyouga freed this powerful tiger-like demon from the 100-Demon Mirror by using the captured Natsuki's blood as sacrifice. Rei is a calm, yet vicious and calculating demon who loves to make people suffer. He has power over fire and can breath forth an illusion-filled miasma that preys on the self-doubt of his victims. Satoru tried to use the Dual Crusher Mixer Head on Rei, but Rei simply broke out of it with his fire powers. Though defeated by Satoru wielding the Crossbow of Fighters, and terminated by Ultimate DaiBouken and the Ashu Spirit Extinguishing, Gajah revived him as Quester Rei (クエスター・レイ, Kuesutā Rei?, 19-42). In this form, Rei wields a sword that also turns into a gun and can also shoot lighting from his hands. He also kept his Ashu ability to project a person's memories and thoughts. He was able to put Natsuki into a trance that made her believe that her purpose as the last of the Lemurians was to bring destruction to the future humanity. After the defeat of Homunculus he was finally destroyed by the Boukengers with the Dual Crusher in Task 42. His name comes from the Japanese word for spirit. While his Ashu form was based on Gosei Sentai Dairanger's Won Tiger, his Quester form is modeled after Kiba-Dai'Oh.

Rei is voiced by Chihiro Suzuki (鈴木 千尋, Suzuki Chihiro?).

Quester Robos
Quester Robos (クエスターロボ, Kuesutā Robo?): Giant mecha used by the Questers integrated with a giant Gōdom Engine, though the first Quester Robo was actually Gajah's second Giant God, Gagadom, which they stole. Each Quester Robo is built with specific combat abilities. Their names are written with a single kanji but are read with a similar or related meaning word in English.


 * Quester Robo Turbo (Rapidly) (クエスターロボ 疾/ターボ, Kuesutā Robo Tābo?, 23): A super-rapid attack specialized robot, it was the first Quester Robo built by Gai and Rei for their plan to destroy the building in which the Precious were kept in order to steal them. It was destroyed by Siren Builder's Triple Liquid Bomber and Ultimate DaiBouken’s Ultimate Buster after Souta's old spy partner, Toba, detonated a bomb installed inside the cockpit. It is based on Kagaku Sentai Dynaman's DynaRobo and Tokusou Sentai Dekaranger's DekaWing Robo.
 * Quester Robo Elite (Commander) (クエスターロボ 将/エリート, Kuesutā Robo Erīto?, 28): A Quester Robo designed for quick enhancing tough weapons or armor. It was designed specifically for it to use the Precious "The Legendary Armor". In the first battle with this Robo, not even Ultimate DaiBouken could oppose resistance to its twin arm cannons and 6-missile launcher, but it was forced to pull out when it started to overheat. It got stronger when finally it could wear "The Legendary Armor" and was impervious to any attack, and gained pair of swords which it used in place of its normal weapons (which were blocked by the armor). However, Masumi suggested to keep on fighting and cause the robot to overheat itself. They finally succeed in taking back the armor and destroy it with a combination attack. It is based on Chikyuu Sentai Fiveman's Super FiveRobo.
 * Quester Robo Cannon (Cannon) (クエスターロボ 砲/キャノン, Kuesutā Robo Kyanon?, Movie): Used by the Questers to destroy the city while getting to Muse just after the Boukengers engaged in battle with the other three Negative Factions. Eiji confronted them aboard Siren Builder and held them off for the others, eventually destroying the Robo with the Triple Liquid Bomber. It is based on Choushinsei Flashman's Flash King.
 * Quester Robo Blaze (Erupt) (クエスターロボ 噴/ブレイズ, Kuesutā Robo Bureizu?, 31): It is inspired on a battle chopper, specializes in airborne attacks. Designed to use "The Fire of the Ruined Country" as it has a special chamber in its head to place it, with it, and through the turbines on his shoulders, this Quester Robo uses an extremely powerful flame thrower that can nearly melt even Ultimate DaiBouken’s armor. It was destroyed by Ultimate DaiBouken’s Ultimate Blaster thanks to Sakura's short-range attack. It is based on Taiyou Sentai Sun Vulcan's Sun Vulcan Robo.
 * Quester Robo Radial (Advance) (クエスターロボ 進/ラジアル, Kuesutā Robo Rajiaru?, 36): It is designed after an armored tank, generating electrical power with its Gōdom Engine. Created to use the Precious "The Mountain Crushing Iron Rod" and cause havoc with it. In the experiments the robo just destroyed a single mountain but in the completed form, it can empower the Precious and not even Siren Builder and Dai Voyager together couldn't oppose it. It was destroyed when the mysterious boy Taro took back the Precious with his bare hand and gave the chance for the Boukenger to use the Triple Liquid Bomber and the Adventure Double Screw. Based on Denshi Sentai Denziman's DaiDenzin.
 * Quester Jet Over (Snatch) (クエスタージェット 奪/オーバー, Kuesutā Jetto Ōbā?, 41-42): A jet created to combine with Homunculus. It controls Homunculus and serves as cockpit for the Questers. It is based on Hikari Sentai Maskman's Masky Fighter. With the Homonculus, it was based on Maskman's Great Five.

Other Ashu Tribe members

 * Hyouga (ヒョウガ, Hyōga?, 17): A blue and black Ashu with a large, icy crown-like horn that he can use to shoot lightning bolts. With Gai, he kidnapped Natsuki and used her blood to free Rei from the 100-Demon Mirror. He is immensely loyal to his fellow Ashu. He was the first to fight the other Boukengers and was defeated by the Dual Crusher Drill Head (wielded by BoukenRed) when trying to protect Gai and physically destroyed by Ultimate DaiBouken after giving a thrashing to Super DaiBouken, but his spirit was completely killed off with the Ashu Spirit Extinguishing. His name comes from the Japanese word for "glacier" or "Ice Ogre." He is based on Gosei Sentai Dairanger's Daimugen. Hyouga is voiced by Kenji Hamada (浜田 賢二, Hamada Kenji?).
 * Ouga (オウガ, Ōga?, 40, 42): The king of the western Ashu tribe, sealed long ago with the rest of his tribe. Ouga was sealed within the mountain by Eiji's ancestors until Rei released him. He seeks and intends to eliminate Eiji claiming that his mother, Kei, who Ouga knew since they were young, cannot complete her travel to the other world with Eiji, the living proof of her "sin", still alive. Ouga's Ashu soul is an "Absorbing Soul" which allows him to absorb life from the surrounding life forms to heal his wounds and perform the technique "Hundred Demons Heat Haze Reflection" to create copies of the Boukenger and attack them. After a harsh battle, Ouga enlarges himself and attacks only to be destroyed by DaiTanken's Bouken Flash. Eiji attempted the Ashu Soul Vanishing, but Ouga jumps at Eiji, placing him in an illusion. Posing as Kei, Ouga intended to make Eiji his prisoner, only Eiji wanted to return to his friends. Ouga refused to accept this, discarding his illusion to kill Eiji. But Kei managed to recreate Kando's shakujo for Eiji to use on Ouga, killing him with the Ashu Soul Vanishing technique. His name comes from romanized term for "Ogre." Ouga's design was based on Hyakujuu Sentai Gaoranger's evil version of GaoHunter. Ouga is voiced by Kazuki Yao (矢尾 一樹, Yao Kazuki?).

Others

 * Ultimate Artificial Lifeform Homunculus (究極人工生命体ホムンクルス, Kyūkyoku Jinkō Seimeitai Homunkurusu?, 41-42): The result of the Quester's complicated scheme of using the other Negative factions in gathering the needed ingredients for its creation, the Homunculus is an extremely powerful artificial lifeform said to be developed by alchemists in Medieval Europe and created by Paracelsus himself. It possess immense physical strength and can fire lasers from its mouth. It took the Mercurius Vessel, the Caduceus Staff, the Philosopher's Herb, and the Paracelsus' Mercury to create. Its only objective is destruction much like the Lemurian Mythical Beast, but through the specially developed Quester Jet Over (Snatch), it could be controlled and was practically invincible. In its first battle it easily defeated Ultimate Daibouken (which fought alone), and then Zuban and DaiVoyager. It was later fought by Satoru in SirenBuilder, who was about to overload its Neo Parallel Engines in a kamikaze until the rest of the Boukengers talked him out of it. The Homunculus was finally destroyed with Voyager DaiBouken's Super Riding Adventure Drive attack, which used Zuban as opposed to DaiBouken's normal sword. The Homunculus is based on Hikari Sentai Maskman's Galaxy Robo and combined with Quester Jet Over (Snatch) it is based on Hikari Sentai Maskman's Great Five.

Precious/Others
Various Precious (プレシャス, Pureshasu?) have also either become creatures or summon creatures that the Boukengers must defeat.

Hyde Gene (ハイド・ジーン, Haido・Jīn?, Movie): A DNA absorbing lifeform from space, collecting the genetic matterial of the most superior lifeform of a planet before executing genocide. Hyde Gene was the true cause of the dinosaur extinction. In the guise of the apparently harmless Muse (ミューズ, Myūzu?), she slept until she felt a new superior life emerging. Once awaken, Muse asks the people on Earth to go to her in order to obtain a most valuable Precious, to which the Boukengers, some Karths and some Jaryuu respond. The only one to make it is Satoru, who learns of Muse/Hyde Gene's intentions. But Kouichi interfered and Hyde Gene confronts the Boukengers, defeated by the Combination Crash. But Hyde Gene regenerated and, deciding to destroy the human race and find another planet, assumes his true form: Stringross. He was finally destroyed by DaiBouken's Adventure Drive and DaiTanken's Bouken Flash. While his regular form is based on Hyakujuu Sentai Gaoranger's GaoIcarus, his true form is modeled after Gaoranger's GaoKentauros. Muse is the only form of Hyde Jean with no actual basis.
 * The Madness Weather (マッドネス･ウェザー, Maddonesu Wezā?, 4): A Precious discovered by a Jaryuu search team at the bottom of a lake. When they activated it, the weather in Japan went crazy. Unfortunately for the Jaryuu, the machine that they used to turn the treasure on shorted out because the treasure was simply too much for the machine to handle. The Maddness Weather was believed to the reason the Antarctic is mostly ice, with Japan next to be turned into a frozen wasteland. GoGo Machines 1 through 5 were buried in ice and snow and fell into a deep crevasse. The Madness Weather later evolved into a humanoid monster form, which gave the Boukengers a hard time, but it was ultimately terminated by DaiBouken Drill's Maximum Penetration Attack, despite the GoGo Drill's power overload problems. It was based on Bakuryū Sentai Abaranger's BakurenOh.
 * Mogari (モガリ, Mogari?, 6): When Gajah stole the Kubi, he activated Mogari, a stone samurai-like monster that protected the Kubi. He captured Natsuki and Sakura, but was eventually defeated by a tag-team effort which involved Souta's Surviblade and Masumi's Radial Hammer. Unfortunately, Gajah revealed that Mogari was simply a switch for the "true" Mogari, a colossal giant that the Boukengers had to terminate using the newly-formed Daibouken Drill and Shovel with the Rising Penetration attack. It is based on Battle Fever J's Battle Fever Robo.
 * The Vril (ヴリル, Vuriru?, 8): It is a tiny, spherical quasi-lifeform that scans and extracts information of any object or being with its three eyes and mimics it, gradually evolving to a more complex form until it can attempt to replace all of humanity. It was found inside a strange metallic container, akin to a Russian nesting doll, mistakenly thought by the Boukengers to have been Orichalcum, the legendary metal of Atlantis. The Boukengers fought and took it from Gajah (what he wanted with it is unknown), whom actually warned them what it really was when the took it, but they of course thought he was lying. Once freed, Vril took the forms of a pen, a piggy bank, a plant, a chair, and Souta himelf. After seizing data from Souta's laptop, Vril-Souta copied the Boukengers' forms, morphing into a clone of BoukenBlue, VrilBlue (ヴリルルー, Vuriruburū?), after Souta attacked it to save Natsuki from it. VrilBlue then multiplied by the hundreds after it was blasted with the Dual Crusher, only to be immobilized by GoGo Mixer. However, VrilBlue and its copies merged to form of an (VERY obviously) imperfect DaiBouken copy. Vril is terminated by DaiBouken Drill and Mixer's Bind Break.
 * Prince (王子, Ōji?, 26): When the Boukenger retrieved the Glass Slippers from Gajah, Sakura was trapped within a Cinderella-like world with the Prince. When she escaped, he showed his true form, that of a monster. He was defeated by GoGo Marine on one of SirenBuilder's water streams. He is based on Bakuryū Sentai Abaranger's KillerOh.
 * Lemurian Mythical Beast (レムリアの幻獣, Remuria no Genjū?, 29): A dragonish giant creature created by DNA manipulation by the Lemurian Civilization as a biological war machine. It is extremely powerful and violent, attacks both allies and foes as its only instinct is destruction. Ryuuwon intended to awaken it and control it using "The Golden Sword", but the Jaryuu Soldiers released the Mythical Beast too soon. Satoru obtains the Sword and destroyed the Beast with a single blow after Ultimate DaiBouken and SirenBuilder resisted its powerful attacks. It is based on Mahou Sentai Magiranger's MagiLegend.
 * Time Demon God Chronos (時の魔神クロノス, Toki no Majin Kuronosu?, Boukenger vs. Super Sentai): The villain of Boukenger vs. Super Sentai, he is a Devil with various clocks and gears on his body who allied with Gajah, who supplied Chronos with three Gōdom Engines, which he used to revive Meemy, Tsutsue and Furabiijo to assist in his plan. In the end, he used the three sorcerers to create a new Precious, the Staff of the Three Philosophers, to make himself stronger and grow giant. He could execute stronger versions of the attacks of the Boukengers' mecha, including a technique called the Triple Screw. His most powerful attack is the DeathWand Kill, which took out the DaiVoyager. It wasn't until AkaRed harnessed the power of Sentai teams of the past and gave it to the Boukengers were they finally able to destroy Chronos and the Precious he wielded with the 30 Super Sentai Attack. He is based on Mirai Sentai Timeranger's Providus.
 * The Three Sorcerers: Three Sentai villains of the past whose magical powers caused the most trouble: Sorcery Priest Meemy, Duchess Org Tsuetsue, and First Lance, Furabiijo. They were brought back by the use of Gajah's Gōdom Engines and Chronos' magic and technology. Meemy was the first to be revived and the only male of the trio (claiming that Chronos had good taste to revive him). He eventually went on to assist Chronos in fighting HurricaneBlue, AbareBlack, DekaBreak, MagiYellow and BoukenSilver and easily defeated them because they refused to work together. TsueTsue was the second to be revived and was rallied by Gajah. The four villains then went to the Rock Quarry where Furabiijo was supposed to appear but she was not present (she was not actually dead, but had been sent to DinoEarth), Chronos was dismayed by this turn of events since he needed all three of the Sorcerers to be present in order for him to fulfill his goal, however Tsuetsue assured him that they could still conquer the world with her and Meemy's assistance. They fought against the Boukengers and their allies and seemed to be losing until Furabiijo finally appeared (she claims to have been delayed because she took a walk). With all three of the past villains present, Chronos harnessed and combined Meemy, Tsutsue and Furabiijo's powers to create a new Precious, the Staff of the Three Philosophers to increase his own powers. When the Staff was destroyed in Chrono's death, the faces of Tsuetsue, Furabiijo and Meemy appeared with words of lament before vanishing.
 * Golem (ゴーレム, Gōremu?, 43): Santa Claus was in possession of this Precious. It was made from clay and other earthen materials that acts like a modern day robot, basically doing as told. Normally it's a small doll, but when the control plate "Shem" is placed on its forehead it grows and starts to move. The plate acts as a controller and when the first letter of its inscription ("Emet," or "truth" in Hebrew) is erased and reads "Met" or "Meit" ("death" in Hebrew), the Golem is deactivated. It was stolen from Santa Claus by Gajah in Task 43 and used against the Boukengers. They destroyed it with DaiVoyager Drill & Shovel. It was based on Chouriki Sentai Ohranger's Gunmajin.
 * Cosmic Kenpō Master Pachacamac XII (宇宙拳法の使い手パチャカマック１２世, Uchū Kenpō no Tsukaite Pachakamakku Jūnisei?): The villain of Juken Sentai Gekiranger vs. Boukenger, Pachacamac XII is an evil descendant of Pachacamac, the first master of Cosmic Kenpō (宇宙拳法, Uchū Kenpō?) who was defeated by Brusa Ee, giving him two jewels that would unlock the secrets of Cosmic Kenpō within the Darkness Pathway ruins in South America. Though sealed on Planet Isla, Pachacamac XII was released by Sakura as he takes her body as his own, forcing Satoru to the steal the red jewel from SCRTC and while he goes after the blue jewel from Confrontation Beast Hall, receiving additional aid from Rio and Mele, who he later put under his control once he gains his ancestor's full power. Pachacamac's fighting moves include Comet Crash (彗星激突, Suisei Gekitotsu?) and Planet Serial Wave (惑星直列波, Wakusei Chokuretsuha?), using the second set of arms to create a super powerful energy orb. Destroyed by the teamwork of Ultimate Daibouken (with Zuban's help), GekiRinTohja Wolf, and GekiFire.
