* Luther Mahoney from ''Series/HomicideLifeOneTheStreet''. Most of the criminals the detectives face are StupidEvil, prone to making mistakes and making themselves easy to catch. Luther, however, is dangerously intelligent and GenreSavvy enough to see their tricks coming, making him a formidable opponent.

* ''VideoGame/DragonQuestX'': Nelgel the Netherlord is perhaps the bona fide poster boy for this trope in the ''Franchise/DragonQuest''series. He destroys Tenton just after the Hero has the Tensu Flower and seals Rendacia in a dark barrier. When the Hero reincarnates as one of 5 Races (Ogre, Wetling, Dwarf, Elf, and Poppet) to avenge Tenton, he appears in the Hero's dreams and holds his Netherscythe to their necks as a warning to stay out of his affairs. Later, they meet up with Sage Horro, who creates a bridge to enter the [[DiscOneFinalDungeon Heart of Hell]], though Nelgel destroys that before it reach his lair. Then, when the Hero has the means to reunite their soul with their old body, he attempts to stop with purple flames, though they escape with the help of Galapagod's true form: [[spoiler: Pegasus!]] Finally, after creaing the Heavenly Ark and fighting their way through to the Netherlord's Throne, Nelgel traps the Hero in dark bindings and proceeds to kill them with his Netherscyhte, though they are saved in time by the Original Owner, who frees them, forcing the Netherlord to fight them to the death. Even after transforming into the [[OneWingedAngel Netherfiend]] and losing again, [[YourPrincessIsInAnotherCastle the seal he created on Rendacia is still active]]!

*** [[spoiler:And once the spaceship with its load of main characters enters the domain of Ultima Thule, what is Meteion's very first move? To attempt to use dynamis to]] ''[[spoiler:erase everyone.]]'' [[spoiler:This can only be counteracted with a timely HeroicSacrifice to overpower the despairing Dynamis with a hope of survival.]]

** [[spoiler: [[TrueFinalBoss Professor Sada/Professor Turo]]. They did everything in their power to ensure that the time machine would not be easily shut down:]]

** Kieran from the Teal Mask and Indigo Disk DLC. [[spoiler: In "The Indigo Disk", when Terapagos first appears, he does not waste any time with preamble. He just comes right out with a Master Ball.]]

** [[spoiler: [[TrueFinalBoss Professor Sada/Professor Turo]]. The professor did everything in their power to ensure that the time machine would not be easily shut down:]]
*** [[spoiler: First, the lab it's in is at the deepest part of the Area Zero, which is swarming with powerful wild Pokémon, including Paradox Pokémon, ensuring that no average trainer would be able to reach it.]]
*** [[spoiler: Second, the time machine can only be shut down using the professor's copy of the Scarlet/Violet Book, something that only their son Arven, who's not particularly skilled at Pokémon battling, would be able to get from the professor's surface lab.]]
*** [[spoiler: Third, any attempt at trying to shut down the time machine, even with the proper credentials, will be stopped by the AI professor, who battles with a full team of Paradox Pokémon. From a gameplay standpoint, not only is their team the highest leveled team before the post-game, and not only do Paradox Pokémon have stats on par with legendaries, but half the team will be guaranteed to be Pokémon that the player hasn't encountered yet, and the other half are species that the player has only encountered recently, meaning that the player starts off with a huge information disadvantage and is most likely scrambling to figure out what the heck they're fighting. As the cherry on top, the last and most powerful of the Paradox Pokémon carries Booster Energy in order to trigger its Ability and gain a stat boost to their highest stat.]]
*** spoiler: Fourth, assuming that someone managed to beat the AI professor, a secondary protocol forces the time machine to reactivate, lock all Pokéballs not registered to the professor, and force the AI professor to send out a hostile version of the box legendary.]]
*** spoiler: Finally, even defeating the Paradise Protection Protocol doesn't prevent the machine from working, it just stops the AI Professor from being controlled by the Protocol. Actually shutting down the machine requires the removal of the AI Professor, one way or another, as it can and will continue to function indefinitely otherwise.]]

* The Amaterasu Corporation in ''VideoGame/MasterDetectiveArchivesRainCode'' features a group of nemeses who don't hold anything back regarding their opposition of the game's protagonists. This is demonstrated in the game's first case, [[spoiler:where the Peacekeepers ''immediately'' try to kill the detectives before they even arrive at Kanai Ward and then frame the survivors]]. And that's just the beginning of the absolute madness the corporation puts the detectives through. Then skip to the climax, and it also turns out [[spoiler:the company's CEO, [[BigBad Makoto Kagutsuchi]], was using the detectives all along, and makes no hesitation in eliminating them as soon as he accomplishes his goal of ousting Yomi, the director of the aforementioned Peacekeepers, from his position of power, using Yomi's overarching plan of manipulating the NDA's chief, Yakou Furio, into killing Dr. Huesca, the company's head researcher, in a SuicideAttack. Albeit, Makoto's plan comes up as a result of ComplexityAddiction, but for a company CEO, his only focus is his extremist goals, so it basically turns it back around to him getting to the point of his villainy again.]]

** Megabyte spends the entirty of the series tryng to infect the Supercomputer, or, as a consolation prize, ruling over Mainframe, but he has a tendaency to gloat and give self-agrandising speeches. By the end of the series he has given up his dreams and dedicates himself entirely to revenge upon those who have wronged him.

* Some recent incarnations of ''Franchise/GIJoe'', including ''[[WesternAnimation/GIJoeResolute Resolute]]'' and ''[[WesternAnimation/GIJoeRenegades Renegades]]'', turn [[BigBad Cobra Commander]] into this, hewing closer to the character as he was [[ComicBook/GIJoeARealAmericanHero in the Marvel comics]], as opposed to the incompetent, often bungling version from [[WesternAnimation/GIJoeARealAmericanHero the Sunbow and DIC animated runs]].

* Benny from ''VideoGame/FalloutNewVegas'', who ''gloriously'' averts BondVillainStupidity. [[spoiler: Both times he has you at his mercy, he straight-up shoots you in the head to be done with it.]] It's nothing short of a bonafide miracle that [[spoiler: you survive not one, but '''[[MadeOfIron both]]''' of the headshots. That or [[ICallItVera Maria's]] damage output being [[GameplayAndStoryIntegration just that]] PatheticallyWeak.]]

* Evil Morty from ''WesternAnimation/RickAndMorty''. His defining trait. When Evil Morty wants something, he will achieve it, no matter the odds, and is smart enough to causally pre-empt any and most threats that could derail his plans along the way, especially anything a Rick throws at him. It says something that he's never once actually suffered a genuine loss in the show, and has made it clear several times that if he wanted to, he could easily deal with Main Rick and Morty, but that's non-essential to his overarching goal of simply living a life away from the Rick-Morty escapades — in fact, he outlines to Morty that it would actually be detrimental to him if he bothered to kill them and inspired vengeance from their family. The ultimate sign of this is him causally taking down Rick Prime, Main Rick's nemesis that he's been hunting fruitlessly for decades, and making it look utterly trivial to do, mainly from annoyance that Main Rick's efforts were interfering with his life outside the curve.

* [[TheAce Kokushibo]] from ''Manga/DemonSlayerKimetsuNoYaiba''. When a fight starts and his sword is drawn, he aims to bring his opponent down and break them completely. The most he'll allow is for a defeated foe to become a demon themselves.

* ''Manga/JujutsuKaisen'': {{Zigzagged}} with [[BigBad Ryomen Sukuna]]; he's ''extremely'' dangerous, clever and powerful, with every appearance he makes always dramatically worsening the situation for the heroes. What stops him from being this all the time is him [[ItsAllAboutMe putting his own wants and desires above all others]], to the point of [[EvilVsEvil being willing to attack Yuji's enemies]] for perceived slights, and refusal to act in benefit of another if he perceives them as coercing him into it. Sukuna is a force of nature, and can equally [[WildCard help or hinder the heroes through his destructive actions]], though his absolute malice towards all is always made clear.

* Kronika from ''VideoGame/MortalKombat''. If nothing else, she's efficient; she is actively working on her scheme to reset existence, even conjuring sand duplicates of other characters to buy her more time, in the final boss battle. [[spoiler:In story mode, losing a round to her gives her enough time to ''succeed'', resetting enough of the world to erase everything and everyone Liu Kang knows; beating her at that point just gives him an opportunity to ensure the next world is a free and happy one.]]

** [[HeroKiller J]]. She has on several occasions just tried to kill Ash. Her battling style also consists of simply [[TheJuggernaut steamrolling any obstacles]] she finds herself up against.
