- Yami Marik, who unlike the other two has no ancient Egyptian backstory, he just kills people.
- The DCU has supervillain Damian Dharc.

Buzz: Android replica.
Buzz: ...Okay, okay, it's so obvious! Zurg's mind control ray. He got to you first!
Warp: Actually, I went to him. Evil is just so much more profitable than good, and more fun.
Buzz: I don't believe it! The Warp Darkmatter I trained side by side with would not work for the most evil force in the universe!
Warp: Look, Lightyear, I've been Zurg's payroll since the academy. Once I got the L.G.M.'s to spill the secret of the Unimind, the Big Z brought me on full-time. My name's Darkmatter! Who's surprised here?

- Horribin the Clown from Tim Powers's The Anubis Gates. An adept of Ancient Egyptian sorcery, who runs a crew of beggars that he crippled himself.

- Dr. Nefarious, a Big Bad in the Ratchet & Clank series (Up Your Arsenal and A Crack in Time).
- Crash Bandicoot: Dr. Nefarious Tropy. Bonus points for having a sinister name even when it's shortened (N. Tropy = entropy). And he sounds like Peter Lorre.

- Globe-trotting millionaire genius super-man "Doc" Savage from the pulp franchise of the same name. Just because he's dedicated his life to using his superior abilities—and his superior fists—for the good of mankind doesn't mean he's not dangerous. Just ask his enemies.

Also, in episodes where the crew play out character roles, Adam often plays villainous characters with "Savage" somewhere in their name (i.e. Baron von Savage, Captain Redbeard the Savage).
- Recurring criminal Shady Shrew from Slylock Fox. This trope is usually extrapolated to other bit criminals like Reeky Rat or Slick Smitty — it's surprising that name profiling hasn't been implemented yet.
- Wonder Woman: Sinestra, a former Nazi spy who turned to kidnapping, human trafficking and scams after Nazi Germany fell.
- Zig-zagged in the H.I.V.E. series, where the Political Manipulation instructor, the Contessa Maria Sinistre, is a HeelFace Revolving Door. The trend stops later in with her granddaughter Lucy Dexter. "Dexter" being an alias to protect her identity, as she would not be able to study at the H.I.V.E. normally if the other students knew she also had Mind Control like her grandmother. However, she is a good character, even one of the series love interests, until her Death of the Hypotenuse fate in book six.

- The Mega Man X games feature a recurring foe named Vile (his Japanese name was VAVA, but it was changed out of fear that it along with his uncanny resemblance to Boba Fett might cause trouble). Originally The Dragon in the first game, he would go on to make repeat appearances as a Wild Card. The Mega Man Zero series would later introduce a Dr. Vile as its Big Bad; this was localized as "Weil".
- The Vile Tribe, the antagonist race from the Lunar series, is widely feared by the "good" races as Always Chaotic Evil, but their situation is more complicated than it first appears.
- The Wonderful Wizard of Oz has the Wicked Witch of the West, who's become an iconic villain in both the original book and the countless adaptations, including her infamously scary incarnation in the 1939 cinematic musical. On the other hand, Gregory Maguire wrote a novel titled Wicked exploring the witch's own point of view and making her significantly less...well, wicked. She does descend into tragic villainy in the end in Maguire's novel, but the stage musical based on the book gives her an even bigger dose of Adaptational Heroism to go with the generally Lighter and Softer tone.
- W.I.C.K.E.D. from The Maze Runner and its sequels. It doesn't stand for anything good, either: "World In Catastrophe: Killzone Experiment Department".
- Dire Wily, the villain to the also significantly named Halcyon Blithe in the series of the same name.
- DePrayve from Werewolf by Night, an evil side of a good scientist who chose to go by that name since he is "depraved".
- Flash Gordon's foe Ming the Merciless.
- Diabolik's name derives from "diabolico", meaning "devilish" in Italian. Double so because he took the name from a panther that was just that terrible (and the man who gave him the name was the one who, after barely surviving the first encounter, actually killed and stuffed the beast).
- The full name of Paperinik, Donald Duck's superhero/antihero alter ego from Italian stories, is Paperinik the Devilish Avenger. Anyone foolish enough to earn his wrath has found out it's perfectly appropriate.
- In If They Haven't Learned Your Name, the Winter Soldier steals a weird aircraft that turns out to be a Nigh-Invulnerable alien spaceship capable of supersonic flight. For lack of a better term, he half-jokingly refers to the spaceship as the USS Motherfucker, a moniker that winds up sticking as he abbreviates the name to just Motherfucker. This is before he discovers that it has destructive capabilities that qualify it as a weapon of mass destruction. Tony Stark approves of the name, naturally.
- Paradise: Awe the dragon. It is mentioned that even the dragons among other races fear him above all else.
- What About Witch Queen?: the Stormbringing Ocean, or Stormbringer for short. It's said that the climate there matches the name and the ships that dare to cross it - so-called pendulums - are giant Cool Boats at least three times as big as regular seagoing ships.
- Domoverse: Sadist, who beat, starved, and turned Issac into a girl, inflicting PTSD on him in the process, and is a Hero Killer.

- A villain who is mentioned by Lucius in The Incredibles went by the name "Baron von Ruthless".
- Spoiler from The Key To Rondo. The kids quickly realize he's bad news, and suspect that he's working for the Blue Queen. Worse, he's actually Leo's Wicked Uncle George, who had given the eponymous Key to the Blue Queen so she could run the world while he lived in luxury.
- Horus Heresy: In a series based on a franchise absolutely encrusted with nightmarish titles, the high-ranking Dark Mechanicus official Urtzi Malevolus has one of the least subtle; most of the others at least did something violent to earn a title like "Flesh Tearer" or "the Red Angel", Urtzi seemingly joined up with a surname that is "malevolent" with the last few letters changed, then got promoted to a high rank.
- The Big Bad in One Flew Over the Cuckoo's Nest is a Battleaxe Nurse named Mildred Ratched, whose surname sounds an awful lot like "wretched".
- The Last Unicorn, has King Haggard, who rules over a Mordor hell hole, has a Pet Demon, and has 99% of the Unicorn population as his prisoners. Truly his realm is as haggard as his name and character.
- Emperor Dayless the Conqueror in Shadow of the Conqueror. His first name was more sinister than his title, as he hails from a world where nights are apocalyptic events. He gleefully took the insult as his own name, vowing to suck the light out of the lives of all his enemies.
- In the backstory of A Song of Ice and Fire, one of the first kings of the Targaryen dynasty was the infamous Maegor the Cruel, remembered for such deeds as killing enemies after they'd surrendered, burning down churches with his dragon, and murdering wives when they failed to give him an heir.
- Robbie Rotten from LazyTown. Granted, he's not exactly easy to run away from, but he's still got a vicious name.

- Treacheron is perhaps the only one of these characters who is misnamed. He is very loyal to his employer.
- The stated backstory of Spike in Buffy the Vampire Slayer reveals that his human nickname was "William the Bloody". In a subversion, it originally referred to his "bloody awful" poetry; it didn't become literal until after he became a vampire. Played straight with "Spike", a nickname that came from his habit of torturing victims with railroad spikes.
- The Prison of the Abject from Emerald City. Lampshaded by the Wizard himself:Wizard: Mistress East and I, we had a partnership.Glinda: The Prison of the Abject.Wizard: Yes, an unfortunate name.West: An unfortunate prison.
- Horrendous, the jock/big chunk of meat who ruled the warrior city from the video game Nox.
- Iosa the Invincible in Iji. How did she earn her title? By surviving a planet-buster completely unscathed.
- All of the Soulless Gods of Lusternia get this treatment: Kethuru the Almighty, Illith the Leviathan, Crazen the Greedy, Great Muud and Zenos the Insubstantial. And yeah, they should all be ran away from very fast.
- BadBad in Secret of the Stars.
- In Mother 3, we have the Natural Killer Cyborg. And yes, it's just as deadly as its name implies.
- One of the bosses in Rogue Legacy is a giant Asteroids Monster with the boss subtitle "The Infinite".
- Bad King Greyghast the Terrible in Embric of Wulfhammer's Castle manages to get "bad" and "terrible" in there, along with "ghast", a sort of monster.
- If a creature in Ryzom has an adjective in its name like "Lacerating", "Rampaging", or "Massive", then unless you are a fairly high-level player (or even if you are a fairly high-level player) you should be running as far away from it as you possibly can.
- The virtual reality-warping soldier that serves as Dr. Eggman's Dragon in Sonic Forces is named "Infinite", though how the name correlates to him in any way is never explained.
- Cutthroat Bill from The Curse of Monkey Island. He introduces himself as just "Bill", and when Guybrush is unimpressed he reveals he's cleaning blood off a straight razor.
- Kaiten Mutenmaru: Sick is the main villain of the second season.
- Raoul Vilain (real-life: Raoul Vilain), who killed French president Jean Jaurès.
- Duncan Ferguson AKA Duncan Disorderly. A Scottish footballer who lives up to his "hardman" image with four convictions for assault (including one on a cop!).
- Atropa belladonna, better known as Deadly Nightshade. When the name of a poisonous plant actually contains the word "Deadly", it's probably sign that you should stay the hell away!
