Anime is filled with unforgettable antagonists—characters who embody darkness, destruction, and moral ambiguity. But what sets some villains apart is their twisted sense of fairness. These are the baddies who commit heinous acts, yet adhere to a personal code of honor, rules of engagement, or a warped justice system. They might slaughter innocents or plot world domination, but they’ll do it “fairly” by their own standards, often respecting worthy opponents or ensuring even playing fields. This unique blend of evil and equity makes them compelling and, at times, almost admirable.

In this top-10 list, we’ll dive into villains from various series who fit this mold. Each entry includes backstory, their evil deeds, and how their fairness shines through—proving that even in villainy, there’s room for principles. Note: Spoilers ahead for the mentioned series.
10. Lord Boros (One Punch Man)
Lord Boros, the self-proclaimed Dominator of the Universe, is an alien warlord who leads the Dark Matter Thieves in conquering planets. His evil stems from his boredom-fueled rampages; having become so powerful that no one can challenge him, he destroys worlds in search of a worthy fight, showing zero regard for the lives he extinguishes along the way. Boros invades Earth, wiping out cities and killing heroes without remorse, all to provoke a battle that excites him.
Yet, Boros demonstrates fairness through his code of seeking genuine combat. He respects strength and prophecy, traveling across the universe based on a foretelling of an equal opponent. When facing Saitama, he holds back initially to gauge his foe’s power, escalating only when he senses true potential. He even compliments Saitama during their clash, acknowledging his might without cheap tricks or interference from his minions. This honor in battle makes Boros a villain who values a fair test of strength above all, even if it means his own defeat.
9. Yujiro Hanma (Baki)
Yujiro Hanma, known as the Ogre, is the strongest creature on Earth in the Baki universe—a martial artist whose sheer power and brutality define him. His evil is evident in his sociopathic behavior: he abandons his family, kills without hesitation (including animals, opponents, and even world leaders in hypothetical scenarios), and treats life as a playground for his dominance. Yujiro’s actions often involve humiliating or destroying anyone who challenges him, driven by an insatiable hunger for combat.

Fairness comes from his insistence on facing opponents at their peak. He refuses to fight weakened foes, often allowing them time to recover or train, as seen when he spares lives to let them grow stronger for future battles. This code stems from his belief that true victory comes from overwhelming fully prepared enemies. In his rivalry with his son Baki, Yujiro pushes him to extremes but honors the familial bond by not killing him outright, making him a villain who blends paternal twistedness with warrior ethics.
8. Char Aznable (Mobile Suit Gundam)

Char Aznable, the Red Comet, is a charismatic Zeon pilot and strategist whose vendetta against the Zabi family fuels his villainy. Orphaned by political intrigue, Char manipulates wars, assassinates leaders, and orchestrates mass destruction, including colony drops that kill millions. His evil lies in his willingness to sacrifice innocents for revenge and ideology, viewing humanity’s flaws as justification for radical change.
However, Char’s fairness shines in his piloting code. He secretly provides advanced technology (psycho-frame data) to his rival Amuro Ray to ensure an equal mech duel, prioritizing proof of superiority over easy wins. As a masked anti-hero/villain, he respects skilled adversaries, often engaging in honorable one-on-one combats without underhanded tactics. This sense of chivalry amid chaos cements Char as a fair villain in the mecha genre.
7. Katakuri (One Piece)
Charlotte Katakuri, a Sweet Commander of the Big Mom Pirates, is a stoic fighter whose Devil Fruit powers make him nearly invincible. His evil is tied to his family’s pirating empire: he enforces Big Mom’s tyrannical rule, participates in extortion, and kills threats without mercy, contributing to the suffering of entire islands. Katakuri’s unflinching loyalty leads him to brutal acts, like suppressing rebellions.
Fairness defines Katakuri through self-imposed handicaps. When he realizes an ally interfered in his fight with Luffy, he stabs himself to even the odds, refusing an unfair advantage. He maintains a perfect image but reveals vulnerabilities privately, and in battles, he praises opponents’ growth. This code of merit-based respect makes him a villain who values earned victories, even against enemies.
6. Kaido (One Piece)
Kaido, the Beast Pirates’ captain and one of the Four Emperors, is a dragon-hybrid tyrant obsessed with creating the ultimate war. His evil manifests in enslaving nations like Wano, forcing labor in weapons factories, and attempting suicides out of boredom—often endangering others. Kaido’s conquests involve mass murder, human experimentation, and alliances with corrupt governments, all to fuel his apocalyptic dreams.
Yet, Kaido upholds fairness in duels. He despises interference, as seen when he apologizes to Oden for an ally’s meddling and gets furious at similar disruptions. He seeks legendary battles, allowing opponents full preparation and honoring strong warriors postmortem. This warrior’s honor amid his beastly nature makes Kaido a fair evil force.
5. Wamuu (JoJo’s Bizarre Adventure)
Wamuu, one of the Pillar Men, is an ancient superbeing who awakens to conquer humanity. His evil includes draining life forces, treating humans as food, and aiding in plans for world domination. Wamuu’s battles involve gruesome wind-based attacks, showing no pity for weaker beings.
Fairness is core to Wamuu’s character as a proud warrior. He gives opponents antidotes or time to prepare, as in his chariot duel with Joseph Joestar, where he adheres strictly to rules despite his superiority. He respects courage, sparing lives if impressed, and fights with chivalry, making him a villain whose code elevates him above mindless destruction.
4. Grimmjow Jaegerjaquez (Bleach)
Grimmjow, an Espada Arrancar, is a panther-like hollow driven by primal instincts. His evil involves invading the human world, killing Soul Reapers, and reveling in carnage—often targeting the weak to assert dominance. Grimmjow’s insubordination and bloodlust make him a chaotic threat.
His fairness shows in demanding peak-condition fights. He orders Orihime to heal Ichigo before battling him, ensuring no excuses for loss. Grimmjow only engages equals, disdaining unfair advantages, and respects rivals’ growth. This feline code of honor turns his villainy into a test of mutual strength.
3. Hero Killer: Stain (My Hero Academia)
Chizome Akaguro, aka Stain, is a vigilante assassin targeting “fake” heroes. His evil deeds include murdering or paralyzing dozens of pros, inspiring copycat villains, and destabilizing society through terrorism. Stain’s ideology justifies violence against those he deems unworthy.
Fairness emerges from his strict code: he only kills heroes who prioritize fame over heroism, sparing those like Izuku who prove genuine. He judges based on actions, not power, and fights honorably without tricks. This warped justice makes Stain a villain who fairly enforces his moral standards.
2. Pain (Nagato) (Naruto: Shippuden)
Pain, leader of the Akatsuki, is a war orphan turned god-like figure. His evil encompasses village destructions, extracting tailed beasts (killing hosts), and plotting global domination via infinite suffering. Pain’s actions cause widespread death, driven by a cycle of hatred.
Yet, he embodies fairness in his philosophy: pain should be shared equally to foster understanding and peace. He offers chances for redemption, as with Naruto, and fights with composed rules, avoiding unnecessary cruelty. Nagato’s code, born from trauma, makes him a villain who fairly distributes “justice.”
1. Meruem (Hunter x Hunter)
Meruem, the Chimera Ant King, begins as a ruthless conqueror devouring humans for power. His evil peaks in genocidal campaigns, treating people as livestock and killing subordinates on whims. Meruem’s birthright arrogance leads to plans for human subjugation.
Fairness develops through his growth, especially in Gungi games with Komugi, where he adheres to rules strictly, respecting her skill despite her weakness. He evolves to honor promises, spare lives if earned, and seek mutual respect in battles. This transformation makes Meruem the ultimate evil-but-fair villain, blending tyranny with enlightened honor.
These villains remind us that evil isn’t always chaotic—sometimes, it’s principled. Their codes add depth, making them more than monsters.
