Despite his wife Nohime's devotion to him, he thinks of her as nothing more than a disposable pawn.

The other members of the terrorist organisation he's part of don't think highly of him, and only keep him because he's the only person to be able to look after the wheelchair-bound leader's health, which he gleefully uses as an excuse to inject psycho serums to the combat-capable members. When the season's climax comes around, he flat out admits that he never shared the organization's views of preventing the world's destruction, and simply wants to save his own butt, with optional plans to repopulate Earth with one of the antagonist Symphogears, hence why he accelerated the Moon's descent rather than stop it.

When the timeline resets so that the war never happened, Lanancuras orders his Kadrian lieutenants to massacre humans and Enterrans alike for failing him.

  • Yu Yu Hakusho:
    • Most famous is the Elder Toguro. In contrast to his honorable Noble Demon younger brother, Toguro freely admits to being a treacherous sadist devoid of honor. In his first appearance, he kills Yukina's only friends, a pair of bluebirds, with great relish. In his first match at the Dark Tournament, he spares two fighters and promises to let one join Team Toguro. When one begs for his life, Toguro kills him...and then kills the other because he just hates keeping his promises. After the death of Genkai, Toguro uses his powers to make a mockery of her in front of everyone, particularly bringing it up to try to break Kuwabara's spirit during their fight, after he had already beaten and impaled Kuwabara repeatedly. His crowning moment of evil was letting the psychic Gourmet devour him... and then he tortuously devoured him from the inside out, delighting in his pain all the while. Later on he would use the Gourmet's powers to eat Yusuke's ally Murota alive. All of these crimes were committed while Elder Toguro was helping in two attempts to open a portal from the demon world into the human world which would lead to the humans being overrun and massacred by the demons.
    • Gonzo Tarukane in the English dub was given more crimes than in the original Japanese. While Tarukane desires wealth above all, he kidnaps the innocent snow maiden Yukina due to her tears producing rare jewels and tortures her physically and emotionally, even having the man who tried to rescue her gunned down. Adding to his crimes, Tarukane puts animals through horrible genetic experiments and founded the sinister Black Black club, making him responsible for the torture and murder of countless innocent demons. Tarukane shows that that humans can be just as vile as even the worst of demons.
    • Chikou is the "father"/owner of Mukuro, the Makai ruler. He outfitted her with cybernetics to turn her into his sex-slave at birth, and started raping her as soon as the procedure was complete. This continued throughout her childhood until she disfigured herself with acid so she'd be too unattractive for him to be interested, at which point he simply threw her out. Just to make sure she wouldn't try to kill him later on, he implanted Mukuro with false memories of him having been nice to her before. He had to implant these memories because he'd never shown her any kindness in her life.
  • Invincible Super Man Zambot 3: Killer The Butcher is The Dragon to Big Bad Gaizock. During the series, this guy commits any sort of horrible action, the mildest of which is mass murder of innocent civilians with the excuse of humans being worthless. One of the crueler of his deeds is implanting mini-bombs inside unknowing human prisoners, just to release them, let them go back to their families, and then blow them up. All the while, he admires his work, is proud of the bloodshed and jokes about the horrible deaths of his victims, treating his killing sprees as a funny game.
  • Zatch Bell!: Zofis, the first Big Bad, was easily the most vile of all the evil demon children. A total sadist and an egotist, he horribly Mind Raped both humans and fellow mamodo, both for practical reasons and for fun, and enjoyed nothing more than the suffering of others. He also kept an army of 100-year-old demons in line by creating the illusion of turning them back into stone tablets, thus being able to control them using their fear. He despised Brago and dreaded his power so much that he attemted to take his life rather than simply burn his spellbook and send him back to the Demon World. Most notably, he warped the heart and mind of Sherry's best friend Koko and made her do anything he wanted her to do, specifically if it hurt Sherry in any way (Koko nearly even jumped to a fiery, burning death because of him). His final threat was to not erase Koko's memory of her time as his partner so that she'd always suffer from the guilt and stay broken as a result.
  • Zetman:
    • Seiji Haitani, also known as Anvil, is one of the many monstrous creatures called Players that escaped the Amagi Laboratories, with his actions throughout the series proving him to be the most vicious of all the Players. He is first introduced sending a Chameleon Player onto a homeless community, killing everyone with the exception of a child, Jin Kanzaki. When the Player fails to kill Jin a second time, Haitani kills him, but not before witnessing Jin's powers as Zetman. Thinking Jin may be useful to him, he manipulates several parts of his life, including setting Jin up with Hanako, to make him more vulnerable later, and impaling him with a power-boosting spike, while gleefully watching Jin kill his minions. He also summons his minion players to wreak havoc on the humans, causing death and destruction on a grand scale. This causes Jin to activate his complete form, which is exactly what Haitani wanted, as it would cause all the players within the vicinity to turn into their true form whether willingly like Anvil or unwilling like Hanako. With Hanako outliving her usefulness to him, Anvil attempts to kill her and was glad that Koga did it for him, knowing this will result in Jin crossing the Despair Event Horizon. Though claiming to be fighting for Players, differing statements about him from other players and his lack of regard for his own contradicts his claims, proving Haitani is solely motivated by sadism and by being the more superior being.
    • Seizō Amagi is the current CEO of the Amagi Corporation, and comes up with the idea of having Players, his father's creations, fight each other to the death for the entertainment of his wealthy clients. When the Players manage to break free from Seizo's control, he leaves his clients at their mercy while escaping on his own, causing many deaths—one of which includes a child of Jiro Nakata, causing the latter's Start of Darkness. In the present, when Jin Kanzaki saves Seizo from the aforementioned Haitani and his Players, Seizo orders his men to kill him simply because he is of the same species as the Players, species and later orders Koga, his own son, to be killed when he tries to defend him. When Koga goes on to shoot him, Seizo uses his wife as a Human Shield, killing her but not enough to prevent his death.

    • Genesis: General Jiin is a cold, ambitious man with aspirations of godhood, ambitions he puts into motion by fatally poisoning his own father and destroying his own home city to assure his rule over the Digald Empire. Treating his own longtime associate Zairin as a pawn to advance his own social standing, Jiin gives him a Zoid called the Volcano with the promise that it will bring ruin to his enemies—while secretly using it to drain his life to fuel his own Zoid and smugly trying to kill Zairin when he learns of this, whilst admitting he always saw Zairin as a pawn. Eventually revealed to be using the souls of thousands of his own citizens to power up his fleet while they're fully conscious and aware of everything, Jiin eventually declares himself an absolute god and tries to take over the entire planet, with the promise that anyone who refuses to prostrate themselves before him will die, even wiping out entire cities to the cause before he's stopped by Ruuji.
  • Zyword, by Tamayo Akiyama: The Goddesses of Chaos were the creators of the dimension known as Zyword and were worshipped by its inhabitants as the benevolent goddesses of the land. However, it was revealed that they were responsible of all the mishaps that happened in the manga, such as the instability of the Zyword dimension. When the heroine, Lunatia Araimel, was 5 years old, the Goddesses quarantined several people because of their hatred of people with tainted blood. When Lunatia develops the hatred with the Goddesses, they gave her their "blessings", which would result in Lunatia getting sacrificed. In the present day, it was revealed that the Goddesses betray the inhabitants of Zyword, and then inflict the curse on the people of Araimel, which causes them to die in an eternal sleep. One of the three Goddesses, Arienna, was revealed to be the person who turned the soldiers of Valstoke into monstrous beings. Another goddess named Shervia manipulated an innocent person to murder two of her younger siblings in order to kidnap the cured Valstoke Soldier, Rain, and then inflicts Lunatia's childhood friend, Roddy, with a manipulative spell; it was also revealed when Lunatia was young, Shervia beheaded the Queen of the Fairy World, which resulted in the world facing its imminent destruction.
