"Our invasion is all that is left...There will be no resistance! Attack, kill, plunder! Our motto is destroy and slaughter. After we completely destroy the nations's society...we can begin the world of our Black Cross Army."Whenever Super Sentai decides to go Darker and Edgier, expect these kinds of creeps tend to appear. Of course, the Lighter and Softer ones might not be excluded from this...
—Black Cross Fuhrer, Anthem of the Black Cross Army, Himitsu Sentai Gorenger
Himitsu Sentai Gorenger:
- Black Cross Fuhrer, later known as Black Cross King, serves as the leader of the Black Cross Army. An alien from the Cassiopeia constellation, he created his army of minions and androids with the express purpose of conquering the world. When threatened by a team of United Nations officers, he would order his men to slaughter all of them in the Japanese branch, leaving only one survivor from each base. He would launch various attacks on the city and was even willing to kill children if it meant advancing his goal. If any of his minions so much as thought of disobeying him, he would kill them on the spot. Nearing defeat, he would use the sacrifice of his most loyal general, Golden Mask, as a way to both escape and carpet-bomb Tokyo, causing untold destruction, not even caring about the death of Golden Mask. Caring only about himself and power, he would also serve as a prototype of countless, diabolical villains of the franchise that would succeed him.
- Star King Bazeu is the leader of Great Star League Gozma and a ruthless sociopath obsessed with gaining power. Years prior he began a campaign of interstellar conquest and subjugation by destroying a planet of winged people so peaceful and kind that merely looking upon their smiling faces and hearing their voices will make you lose all violent impulses. Many of his forces are either comprised of the champions of those worlds he'd already conquered, forcing them to fight for him lest he finish the absolute destruction of their homes. Not that he intends to ever let them go back, as his true form is the size of a planet, and he eats the planets he conquers. He also uses innocent beings from the worlds that he’s conquered and forces them to fight for him by forcefully mutating them into his soldiers against there will. A wicked abuser of his forces, those who fail him are punished by a beam fired from his head that causes them immense pain. Years after his debut, Bazeu stands out as one of the absolute worst villains in the franchise.
- Great Professor Bias is the prime example of corrupters in the franchise. Having corrupted three geniuses before the show began, turning them into his students, Bias has them massacre the remaining geniuses at Academia. After kicking out Goh Omura and attempting to kill him, Bias recruits the aliens Guildos and Butchy. When Guildos tries to prove his superiority through Guild-zuno, it is revealed that both aliens are actually robots built by Bias to make the humans try harder, which he coldly tells Butchy to his face after Guildos's death. After Butchy is convinced to defect, Bias blows him up. Goh later realizes that Bias only wants his students for their brains, one of which will be used for the Giga Brain Wave, which will turn all humanity into Bias's slaves and make Bias immortal. After Yusuke saves the world from the Giga Brain Wave, Bias is reverted to a child who shifts his goals from conquest to destruction and mocks Megumi's kindness when she offers it before finally rejecting redemption.
- Vulgyre killed Princess Meadow for rejecting his attempts to covet her. Impersonating her, Vulgyre created the Galactic Imperial Army Zone, planning to use it to destroy 1,000 inhabited planets in a bid to become the immortal God of the Milky Way. Coming to Earth after destroying the other 999 planets, Vulgyre forcefully transformed his own General Doldora and her subordinate into a mindless monster after they refuse to continue to serve him after discovering his true nefarious plan. Corrupting Chevalier's soul by charging him with the blood of his victims, Vulgyre intends to have Chevalier killed as a power-up for himself. Becoming Galactic Super Beast Vulgyre, he unleashes his final assault on the city and it is revealed Vulgyre has kept Meadow's soul captive for his own selfish needs.
- Back Dimensional Count Radiguet seeks to establish and rule a dictatorship over the Dimensional War Party Vyram and Earth. Attempting to overthrow Empress Juuza, Radiguet fails and is banished to Earth with his memories removed, meeting a dying girl whom he unknowingly cures and then becomes the lover of, only to murder her immediately after having his memories returned. Doing anything to gain power, Radiguet aids the Jetman in killing Juuza and takes advantage of the Jetman defeating his rival to torture him to insanity. Gaining a lustful obsession with Rie, Radiguet brainwashes her into becoming his servant and when it wears off, spitefully kills her to prevent her from being with anyone else.
- Lieutenant Colonel Shadam cares nothing for his two sons and wife, as shown by his amazingly abusive treatment to Akomaru. He also shows zero honor: When Doushi Kaku showed mercy for him and the tables were turned for his side, Shadam instead uses the chance to mercilessly and brutally murder Kaku through an utter Curb-Stomp Battle. He also doesn't care about any of his subordinates; they are clay dolls created by him and he plans to discard them once they are useless to him. He doesn't care about his master either. It's all about him in his head.
- Commander Guirail is a seriously depraved creature with love of underhanded tactics, whatever it takes to win. Even children wouldn't be spared. His favorite tactic seems to be using human shields. Anyone's fair game, even his ally Yugande: After "tricking" him to work together for the common cause, Guirail makes him take full brunt of damage when the chips are down against him. He's the only one amongst Nejirejia Kingdom who knows nothing of "family/companionship" value: The moment Yugande was subjected of those things, both Hinelar and Shibolena were thoroughly disgusted and socked him with a Psycho Serum under the guise of power-up in revenge of what he did to Yugande.
- Grand Witch Grandiene is the Evil Matriarch of the Saima Family and the ultimate form of all the minus energy in the universe. After Dark King Salamandes's death, Grandiene takes matters into her own hands and used the evil energies gathered by him and his siblings to complete her revival. Then, in a cruel and cold act, Grandiene sends her own son Beast Baron Cobolda to his death to accomplish her goals; revealing to Dark King Zylpheeza that she never really cared for the well-being of her children. After the destruction of her physical body, she possesses Zylpheeza and revives Salamandes as a soulless Destruction God in a final attempt to wipe out humanity. As fitting of the family theme in GoGoFive, Grandiene stands for everything the Tatsumi family bond isn't.
- Captain Ryuya, the descendant of Tatsuya Asami, serves as the ultimate mastermind behind everything that occurred in the series. He helped Don Dolneiro to escape from captivity and releasing the other Londerz prisoners who would wreak havoc on the present, with one even trying to release a virus to poison an entire city. He would later drive Gien—who was a 5-year-old—to insanity, which lead to his death. He was responsible for the crisis that took place in the finale (he had seen two futures—one in which 1/3 of the 21st century is destroyed and one in which the 31st century ceases to exist). Willing to kill billions of innocents to save his own hide, he is everything the Timerangers are not.
- Wicked Life God Dezumozorlya, worshipped by the Evoliens as a God of Evil, has launched genocidal wars against innocent planets for no reason other than bigotry, for fun, or because the people of those worlds refused to worship him as a god. It also stands as the only rapist in the entire franchise as it brainwashed Mahoro so she could give birth to Lijewl and cares nothing about the fact that its acts are despicable. Despite his belief in his superiority to other lifeforms, Dezumozorlya demonstrates cruelty and sadism, such as how it takes sheer delight in the destruction it causes in the finale, which shows it is Not So Different to the beings that it despises.
- Agent Abrella sold many weapons supporting galaxy-destroying wars for fun and profit to most of the Alienizers, regardless of how many lives were taken. Once a galaxy is destroyed, he moves to the next to generate profit and destruction. Abrella treats any and all crime as a business opportunity, and it doesn't matter if you're destroying cities, selling slaves, pawning stolen merchandise, or filming child pornography, as long as the price is right, he'll be more than happy to sell you the tools you need to further your enterprise. And his Villainous Breakdown near the end of the series was caused merely because the Dekarangers were ruining his transactions. Yes, Abrella himself caused a citywide destruction spree and nearly destroyed the whole of the Space Police ''just so he could keep his job''.
- Hades Wise God Dagon, leader of the Infershia Pantheon of Hades Gods, is dedicated to the revival of the Dark God N Ma. Adhering to the Dark Precepts, Dagon shows no regret in executing his fellow God Ifrit when Ifrit fails to defeat the Magirangers within a time limit. Dagon soon shows his true colors by cheating, and when the good-hearted Hades God Titan attempts to seal away N Ma within himself, Dagon ambushes and kills him, releasing N Ma to devour Magitopia, earth and even Infershia as well. Betraying and attempting to kill his honorable companion Sphinx, Dagon later rejects her offer to ally with the humans, claiming all he desires is destruction and to see "the ultimate nightmare."
- Long the Infernal Dragon is the true leader of the Genjūken. Growing bored of his ancient immortal life, Long manipulates humanity and is responsible for hundreds of years of war and strife. Eventually deciding to destroy the world to alleviate his boredom, Long tries to corrupt Maku into the god of destruction, succeeding in turning him to the dark side, though his omnicidal goals are stopped. Trying the same with Jan and Rio, years later, Long destroys their hometown, killing Jan's parents and brainwashing the soul of his dead father into becoming one of his generals and trying to get him to murder his own son. Also corrupting Rio, Long acts as his right-hand-man, while truly guiding him down the path of evil in the hopes of cultivating the destruction he desires.
- Sujigarano Akumaro shows that a Villain can take a show to even darker levels even if it was already fairly dark to begin with. The Gedoushu at large wanted to create enough anguish to cause the Sanzu River to rise high enough to flood the world of the living, thus enabling their incursion thereof. Akumaro, on the other hand, wanted to open a portal to Hell because he wanted to enjoy absolute human suffering—even though said opening would destroy both the human world and the Sanzu River. He also made Fuwa Juzo's sword from Juzo's dead parents, whom he murdered himself. His monstrosity extends to even the Ayakashi who serve under him; they seem specifically made to cause as much suffering as possible in order to further his goal which was to use the suffering of people as a wedge into one of six precise points along a line, at the center of which was a portal to Hell for his sinister purpose.
- Fuwa Juzo was a remorseless Blood Knight to the point that even his fellow Gedoushu wouldn't trust him; he even only became a Gedoushu in the first place so that he could keep killing in spite of his sickness. Akumaro saw potential in him for his ability to walk the line between humanity and the Gedoushu and sought to use him to open the gates of Hell. However, he throws a sharp wrench into the plan, declaring that he already knew that his sword made by Akumaro was made of his parents—a fact which Akumaro had recently told him to bring him to a Despair Event Horizon—and that he didn't care.
- Buredoran/Brajira of the Messiah is a fallen Gosei Angel seeking to destroy and rebuild the world because he deems it corrupt. In the distant past he murdered his allies to become more powerful, after which he escapes into the future, where he manipulates an alien army into invading Earth and unseals monsters born of pollution he himself sealed away to do his dirty work. After his memory is erased and he is enslaved by Robogog, he develops a relationship with Metal Alice. Together, they restore his memory and destroy Robogog. As thanks, Brajira murders a wounded Metal Alice. Brainwashing Gosei Knight, Brajira tries to enact his plan by using massive drills to destroy the world. When fatally wounded, he decides to just destroy the planet anyway, even though he can’t make a new one. While claiming the world is corrupt, his attitude and omnicidal tendencies expose his noble motives as hollow and prove him to be just a madman with a god complex.
- Basco ta Jolokia represents Selfish Evil, and is far worse than his boss and his replacement/dad. He betrayed the Red Pirates, leaving Aka Red to his apparent demise and Marvelous alone, while stealing several of their gathered treasures under the pretense that "you have to sacrifice something to get something else", which means that if he wants something, he sacrifices anything to get it and isn't above blackmail. He would hurt children, blow up schools and youngsters, and betray allies, including the Morality Pet, for anything he wants. He does all that with a cheery smile befitting of a Troll and did it for profit and whatever fun he wants. Basco's disposition is usually cheery and jovial, but when he is the main focus, the situation gets even worse than when Space Empire Zangyack is the main focus.
- Enter/Dark Buster is responsible for turning innocents—including children—into his robot slaves and using them as human shields, showing sickening amusement with his own cruelty. After the destruction of his boss, Enter takes over as the new Messiah, seeking to assimilate all of Earth to rule supreme. Turning the heroic Hiromu into a Soul Jar to allow himself to continuously regenerate if defeated, Enter forces the Go-Busters to considering killing their friend to stop him. When Hiromu threatens to kill himself to stop Enter, he tries to put Hiromu into a coma to force him to become a docile part of his nefarious scheme.
- Ferocious Knight D is one of the first and most remorseless Deboss Knights in existence. Debuting as the main villain of Gaburincho of Music, he was released after 100 million years of slumber, receiving Fake Kyouryger powers transforming him into Deathryuger. Kidnapping a friend of Daigo named Meeko in an attempt to resurrect Tobaspino and use the former as a power source for Spinodai-Oh as part of his genocidal plan to wipe out all life on Earth. Upon defeat he later returns in the series proper, where after escaping from Deboss Hell, D turns Meeko into his personal necromancer, with the intention of making her resurrect the various fallen monsters in his plan to conquer the planet. When the Kyoryugers thwarted his latest evil plan, D attempts to blow up the Earth by enlarging himself out of spite.
- Lord Ginis, an alien with an Inferiority Superiority Complex, despises being made of Moebas, beings he looks down upon. Creating the Deathgaliens, Ginis uses them to serve as his warriors in the "Blood Games"—wherein he challenges and destroys other worlds—currently having done so to 99 planets and now targeting Earth. Creating an ever-collapsing barrier around planet Earth, Ginis plans to allow it to destroy the world unless the heroes managed to deactivate it. Although his barrier is stopped, Ginis sets up a destructive robot to continue his genocidal plans. Cunning and manipulative, Ginis tricks the friendless Misao Mondo(u) into becoming his servant and hires a sadistic alien hunter to make his "game" of planetary destruction more interesting for himself. When one of his men betrays Ginis after finding he was responsible for the destruction of his home planet, Ginis defeats and spares him, before watching with amusement as the broken man insanely destroys everything in his path. After all but one of his followers are killed, Ginis decides to end the Blood Game by injecting his cells into the core of the Earth, wiping it out entirely. Incapable of loyalty or gratitude, when the Zyuohgers discover Ginis's body to be made of Moebas and reveal it to his last remaining follower and she declares her loyalty to him in spite of this, Ginis, cruel to the end, kills her off for daring to pity him.
- Kuervo/Quervo, the ex-best friend of Tsurugi Ohtori, supposedly died blocking an attack from Don Armage for Tsurugi. Secretly, Kuervo only sacrificed himself so he would be known as a hero throughout the universe. After Armage was apparently defeated, a dying Kuervo allowed Armage's essence to possess him so he could become more powerful. Unlike Armage's other hosts, Kuervo maintained his complete identity, allowing Armage to use him as a host to take over and subjugate the universe. Once they've conquered most of the universe, Kuervo and Armage began construction on a bomb made of Planetium, which Kuervo intended to use to destroy the entire universe so he could recreate it from scratch. After having Armage purged from him in his final battle with the Kyurangers, Kuervo is given a chance to redeem himself by Tsurugi, only for Kuervo to attempt one last attack on him, revealing that he never considered Tsurugi a true friend and was always resentful of Tsurugi for being more powerful than him.
