- 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.

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 hes 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.

Guirail also tricks his own allies into being subjected to horrible experiments while being unconcerned about collateral damage.

Even his own allies are revolted by how far Guirail is willing to go and are more than happy to set him up to his own end.

- 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.

- 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 Gedōshū 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.
- Fuwa Juzo was a remorseless Blood Knight to the point that even his fellow Gedōshū wouldn't trust him; he even only became a Gedōshū 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 Gedōshū 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.

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; hurting children; blowing up schoolsand the students; and betraying allies, including his supposed Morality Pet Sally, for anything he wants. He does all this with a cheery smile, and 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.

Although his barrier is stopped, Ginis sets up a destructive robot to continue his genocidal plans. Cunning and manipulative, Ginis tricks the friendless Misao Mondō into becoming his servant and hires a sadistic alien hunter to make his "game" of planetary destruction more interesting for himself.
