Beware The Superman / Anime & Manga

• In Akashic Records of Bastard Magic Instructor, criminal mages freely do things like human experimentation and demon summoning, and there's little that non-mages can do to stop them. Glenn's previous role as a Mage Killer involved dealing with such mages.
• AKIRA: Tetsuo is a massively powerful psychic with zero restraint, using his powers to take over Japan the moment he realizes nobody could stop him.
• Baki the Grappler has a setting where with enough training a martial artist can rival armies in strength. There are three particularly notable examples here. First is Biscuit Oliva, a man so strong he takes down entire drug cartels by himself for the U.S government and uses a supermax prison as a penthouse. Then there's Che Guevara, the ruler of an island nation who is strong enough to casually assassinate world leaders if he ever felt his nation was threatened (and he has soldiers who can do the same). Last is Yujiro Hanma, explicitly the Ultimate Life Form and the Big Bad of the series. To get a good grasp of how powerful he is; he singlehandedly won The Vietnam War and used George W. Bush as his chauffeur afterward. Not just Bush either, he's made every single President in recent history Kneel Before Zod.
• Beastars: Carnivores in the setting are all freakishly strong compared to herbivores, and they typically come with other superior physical attributes like the ability to see in the dark. They also have the tendency to kill and eat herbivores. Tragically, this inclination only exists because Herbivores are so afraid of them. Most carnivores' natural inclination is actually to protect herbivores. But because the consumption of meat is illegal in their society, they're forced to live their lives getting what little nutrients they can out of egg sandwiches and tofu, so even when their bellies are full they're always starving.
• Geass users in Code Geass might qualify if not for the fact that regular, non-geass-possessing individuals are still responsible for most of the world's woes anyway; it's just that pretty much everyone with a Geass tends to add even more misery on top of that.
• Cheat Magician Life That Started From Being Judged Useless: Discussed. Kento manages to corner Princess Camilla Resenberg and puts forward negotiations for dealing with the fact that Camilla unilaterally summoned, enslaved, and abused 201 8th grade students and some teachers, including Kento himself. When Kento gets to the part about everyone being repatriated back to their homeworld, Camilla points out why the class was treated so horribly. Turns out the royal family has the official history of other-world summoners and with 100% certainty, the summoned ultimately turn out to be far, far worse than whatever it is they were summoned to fight, at least if the official history is to be believed.
• In Darker than Black part of the package deal that makes you into a Contractor is a loss of emotions and conscience: All Contractors are, per definition, sociopaths. But they're also rational sociopaths and can thus see the inherent futility in trying to use their powers to Take Over the World. That said, the world is most definitively worse off for their appearance, especially what with all the wars that are being fought with Contractors as human weapons.
• Don't Meddle with My Daughter!:
  • The superheroine Wonder and her daughter, the new Eighth Wonder, are the most powerful members of the agency N.U.D.E., and the other members worry that "if Eighth Wonder loses control, it'll be the end of the world."
  • In the second volume, the new Eighth Wonder falls victim to a mind control device and goes on a rampage damaging the city she lives in. She then attacks N.U.D.E. headquarters, and corners the staff in a reinforced bunker. The only reason she didn't burst in and kill them all was because her mother, the original Eighth Wonder, intervened, and after their fight demolished most of the base, the original ends it by putting her daughter over her knee and giving her a spanking.
• Dragon Ball:
  • Frieza and his family are supremely powerful mutants who use their power to run an interstellar syndicate and slaughter billions of innocent people.
  • The gene-optimized murderer Cell doesn't even bother trying to empathize with those he consumes to become stronger or, later, tortures and kills for no reason other than his amusement.
  • Dragon Ball Super: Goku Black, Goku's Evil Counterpart and the Big Bad of the Future Trunks Saga, who's essentially a chilling psychopath with all Goku's power at his disposal. And this is before the revelation that Goku Black is actually an alternate timeline version of the Supreme Kai-in-training Zamasu in that timeline's Goku's body.
  • Beerus states that this trope is exactly why Zeno is so feared. Because of his power and authority, no one is willing to go against him. He can casually and innocently threaten people with Cessation of Existence just to get them to play with him, and since no one is willing to tell him why it's wrong, he never understands why it's wrong to do so.
  • Dragon Ball Z: Broly – The Legendary Super Saiyan: Broly was born with an overwhelming Power Level of 10,000, and King Vegeta, fearing the threat the newborn might pose to his empire, ordered his execution. As Broly gets older, he gleefully destroys entire planets and punches out his father's left eye when he tried to stop him, forcing Paragus to slap a Power Limiter on him.
• Gundam:
  • Mobile Suit Zeta Gundam: Paptimus Scirocco is a Newtype supremacist who wishes to eliminate all mundanes.
  • After War Gundam X: Several belligerents use Newtypes to enhance their weapons and one side even uses Newtypes' existence to justify a racial/cultural supremacy ideology. Most of the existing Newtypes are reasonably nice people, but their existence has made the world a more warlike place. It is also implied people are less likely to look for solutions to the problems of war and conflict because they expect Newtypes to resolve them.
• Magical Record Lyrical Nanoha Force: Most of the Huckebein are "just" Smug Supers proud of their seemingly flawless Anti-Magic, but their more vicious members like Cypha go straight into this.
• Sorcerer Hunters has a magical version where the 'supermen' in question come in the form of Sorcerers who for most part, make life very miserable for the Parsoners who live on Spooner. It's even stated that the Sorcerers are treated as nobility as a way to keep them under control (with the eponymous Sorcerer Hunters as a stick to go along with the carrot).
• Fairy Tail has about 10% of the population able to work magic but so far we have not seen on screen magically powerful despots. The closest the setting has is probably Zeref or Acnologia. One of the humans empowered by dragons with Dragon Slayer magic, he eventually turned on his benefactors and became a dragon himself by bathing in the blood of a hundred dragons; a rather literal use of this trope. Another example is Grimoire Heart's "ultimate magic world plan" where people without magic would be killed and only those strong in magic would survive.
• Death Note gives us Light Yagami, a brilliant and beautiful teenage boy granted a godlike magical power. Unfortunately, that power happens to be the titular Artifact of Death, and When All You Have Is a Hammer… no matter how well you intend to use your power, you go flying off the slippery slope faster than you can say "justice". The same happens to his girlfriend Misa.
  L: If [this person] is an ordinary human being who somehow gained the power, he is a very unfortunate being.
  • Not to mention the fact that the only people who can stand against them are cutthroat, coldblooded investigators who are, when push comes to shove, not that different at all. The rest of the world just gets caught in the crossfire.
• In Hunter × Hunter, while there are a large amount of Nen-enabled fighters who genuinely want to do good for the world, there are just as many, if not more, of those who gain these superpowers and use them purely for personal gain. Most of the really powerful ones see themselves as above anyone who cannot give them a good fight and casually mass-murder Muggles and less powerful combatants for trivial reasons like chasing after people, stealing valuables, or simply out of being in a bad mood. These mass deaths are so common that everyone, even the muggles, see them as no big deal and the survivors simply move on as soon as the danger has passed.
• The first users of Psychokinesis in From the New World, who brought about the end of the modern age when they abused their near-limitless power for indiscriminate violence and governments tried and failed to contain them with military force, then with nuclear weapons.
• Downplayed in Pokémon: The Series. Pokémon have been used by villain teams and villains of the week alike, but not only are Pokémon a part of everyday life in the Pokémon world to the point that no one tries to ban Pokémon training, but much of an individual creature's power comes from training, which humans can undergo as well. Legendary Pokémon are the exception, however, and are portrayed as far more powerful than they are in the games or manga series.
• Played for Laughs in Love Hina: The Shinmei-ryū style of kendo was created specifically for protection and Demon Slaying. Motoko Aoyama, the heir to the school, is a borderline Ax-Crazy girl with a Hair-Trigger Temper who uses these skills to assault anyone who even slightly irritates her, dealing a lot of Amusing Injuries.
• Inuyashiki is a story about two people, an old man named Ichiro Inuyashiki and a teenager named Hiro Shishigami, who gain superpowers from a UFO crash. While Inuyashiki decides to use his powers to help people, Shishigami becomes a superpowered Serial Killer.
• My Hero Academia:
  • In the backstory, when Quirks first appeared, normal humans were terrified and demanded strict limits be placed on what they were allowed to do. While by the time of the story 80% of the population have Quirks, it's made clear that they weren't wrong to do this. Villains cause major disruptions on a daily basis, and All For One is simply a random man who decided to use his power to hurt and manipulate everyone around him.
  • My Hero Academia: Vigilantes: Number Six mentions that this is why All Might adheres so strongly to Villains Act, Heroes React. He is the strongest in the world by a huge margin—if he was more proactive, he could annihilate crime. But even if his judgment was absolutely perfect, it wouldn't take long for people to worry that he might come after them next. By acting only to keep people safe, everyone loves him, but it means he's not as effective as he could be.
• Talentless Nana:
  • Superpowered individuals called "The Talented" suddenly started being born. They had incredible powers such as control over the elements, the ability to manipulate time and space, and even predict the future—there seemed to be no limit to what they could do. Unfortunately, many of them quickly grew to gravely misuse and abuse these "Talents", causing untold amounts of havoc, chaos, and death. The government attempted to create its own superhero squad of law enforcement to control the lawless Talented—until they started abusing that authority, too. It was only the appearance of the mysterious and deadly "Enemies of Humanity" that regular humans and the Talented were finally united, the latter being sent to special schools and facilities to train and serve as the first-line of defense against these monsters. In truth, the "Enemies of Humanity" don't exist. The government is just sequestering the Talented to exterminate them, doing whatever it takes to prevent another Talented-induced catastrophe ever again.
  • Later in the story, we discover that Nana's handler is an unrepentant The Corruptor who ruined Nana's life and intentionally turned her into a Serial Killer for sport, then took one of her Talented victims and turned him into a murderous supervillain. It's implied that the government in general also doesn't actually care about Talented supremacy, just the uncontrollable threats to their regime.
