Hero Killer

Go To
"I know what it's like to lose. To feel so desperately that you're right, yet to fail nonetheless. It's frightening... turns the legs to jelly. But I ask you, to what end? Dread it, run from it... destiny arrives all the same. And now, it's here. Or should I say: I am."

"Jedi: you are surrounded, your army is decimated; make peace with the Force now, for this is your final hour. But know that I, General Grievous, am not completely without mercy: I will grant you a warrior's death. Prepare."
General Grievous, Star Wars: Clone Wars

In many works of fiction The Hero isn’t the only hero doing good out there. These other heroes might be recurring minor characters or part of The Order, and may have little impact on the central narrative, but they are heroes nonetheless, often the greatest warriors in the land, conquering evil without fear.

That is, until the Hero Killer comes along.

Exceptionally powerful, incredibly skilled, the Hero Killer has one purpose, which he pursues ruthlessly: kill the heroes. He will hunt down the greatest knights and he will slaughter them, one after the other. What makes him so powerful? Maybe he knows how to exploit heroes' weaknesses. Maybe he was engineered for that very purpose. Maybe he made a Deal with the Devil. Maybe he is fuelled by exceptional determination. Regardless, he has earned a reputation for curb-stomping heroes regularly and reliably, often without exception. Expect a No-Holds-Barred Beatdown and/or Curb-Stomp Battle should his prey be unprepared.


Even the noblest, most powerful heroes will quake in fear at the sound of his name. This reputation is indeed key, as ironically they may never be seen actually killing anyone important first hand because of the lack of a Sacrificial Lion or C-List Fodder to put in their way. Similarly, a hero can die without their killer being a Hero Killer, although their reputation might explode into being someone they are not.

Closely related to The Dreaded: Their legend may inspire the heroes to train and improve their skills throughout the story, fleeing or avoiding the Hero Killer until such point as the hero is finally ready to face him; even then, they're probably going to need everything they have to stand a chance. If the hero gives the Hero Killer a run for his money, it may be a Moment of Awesome; if he wins, he's defeated the undefeatable. With that in mind, remember character deaths are required for a character to qualify, be they in backstory or present plot.


This character usually invokes The Worf Effect and is often a grim reminder that Anyone Can Die if the work is dark. If the work was fairly light-hearted before this guy appeared, then he's a Knight of Cerebus. He is very often the "Goliath" in a David vs. Goliath scenario. If he's very dogged in his pursuit of heroes he overlaps with Implacable Man. In video games, contrast That One Boss, which is when it is the player and not necessarily the characters that has difficulty beating an enemy.

Since this is a Death Trope, SPOILERS AHEAD.

    Anime & Manga 
  • D.Gray-Man: so far, Tyki Mikk has put Suman Dark in a Superpowered Evil Side that eventually killed him, curb-stomped Daisya Barry before having his butterflies eat his heart, killed General Yeegar with the assistance of Road and put Allen in a state that is so close to death, his Innocence had to save him (His arm was already almost destroyed by overloading it trying to save Suman Dark, but Tyki found it neccesary to kill off Suman´s still alive body before his eyes, rip off his arm and disintegrate it, crushing what seems to be his innocence before his eyes and then having a teez eat a hole in his heart). and even when he looked defeated, he instead went into a One-Winged Angel form that took a new character gaining his innocence AND General Cross to show up for them to survive. Hero Killer indeed.
  • In Berserk The Apostles and by extension Femto aka Griffith massacre Corkus, Pippin, Judeau, Gaston and rest the Band of Hawk as a sacrifice during the Eclipse. Only Guts and Casca make it out alive, albeit raped and missing limbs and an eyeball. Cue Roaring Rampage of Revenge.
  • Dragon Ball:
    • Great Demon King Piccolo from Dragon Ball was the original Hero Killer. His actions lead to the deaths of Krillin, Master Roshi, and Chiaotzu. He also ordered the deaths of dozens of martial artists and killed Shenron after getting his wish from the Dragon Balls (something no other villain in the series has attempted before or since).
    • In Dragon Ball Z, Nappa directly killed Piccolo and his actions led to Tien and Chiaotzu's deaths by attempted Heroic Sacrifice. In addition, one of the Saibamen that he and Vegeta used managed to kill Yamcha by blowing him up.
    • Frieza set the standard to follow for many Dragon Ball villains by killing Dende, Vegeta and Krillin (and almost Gohan and Piccolo). In the Resurrection F Saga, he kills Piccolo and then destroys Earth after being beaten by Vegeta in his Super Saiyan God Super Saiyan form. Fortunately, Whis rewinds time to give Goku a second chance to destroy Frieza for good.
    • The Androids were this in the timeline Future Trunks came from; he and Bulma are the only main characters still alive before the timeline was altered, though Dragon Ball Super would later expand this number to include Android 8, Turtle, and Yajirobe.
    • Cell kills Future Trunks in the original Future timeline in order to get into the present day, where he kills Android 16 and Future Trunks again, and forces Goku to make a Heroic Sacrifice to stop him from blowing up the world.
    • Majin Buu is the most prolific example for this series. He killed the entire cast, except for Goku, Vegeta, Dende, and Mr. Satan, along with the Earth's inhabitants before blowing up the planet. And before he was even introduced, he had already killed or eaten several GODS.
    • The Demon King Dabura, a minor villain in the Buu arc, kills Piccolo by turning him to stone (though Piccolo is brought back later), does the same to Krillin, and incinerates Kibito with one blast. But what really gets him a spot here is his actions in the alternate timeline (as seen in the Dragon Ball Super manga) that Future Trunks is from. He kills Kibito again, kills the Old Kai by smashing the sword he was trapped in, beats down Future Trunks, and kills the Supreme Kai just for good measure.
    • In Dragon Ball Super, Goku Black makes his debut by killing Future Bulma, who was the one that provided the Time Machine for Future Trunks. He also severely wounded Future Mai who luckily turned out to be alive. He's also killed both Alternate Present and Future Gowasu, Alternate Present Goku in his old body, Alternate Present Chi-Chi and Goten, and the Supreme Kais from every other universe in his timeline except U7.
  • Many of the Big Bads in JoJo's Bizarre Adventure earn a frightening reputation among the heroes by taking out some of them out prior to the final confrontation.
    • During Part 1, Dio Brando kills Dire during their battle, and then Jonathan Joestar, the main character himself in the final encounter. When he returns in Part 3, the heroes know that he is an enemy to be feared.
      • During the final battle of Part 3, DIO adds Kakyoin and Joseph to his body count (although the latter was resurrected with DIO's blood.)
      • Vanilla Ice also deserves a mention. He might be just a loyal minion of DIO, but for these standards two hero kills (Avdol and Iggy), and a near-victory over Polnareff are impressive.
    • In Part 5, Vento Aureo, Diavolo turns up, and justifies his name by killing Bucciarati, Abbachio, and Narancia, with Polnareff almost joining them. That's half the good guy's team!
    • Part 6, Stone Ocean, brings us Father Enrico Pucci, who kills Foo Fighters and Weather Report prior to the final battle. And during said final battle, he kills every single remaining hero except for Emporio.
    • Near the end of Part 7, Steel Ball Run, we have Funny Valentine, who's killed Wekapipo, Diego Brando, Hot Pants AND Gyro Zeppeli, the latter three of whom were thought to be characters with at least a certain degree of Plot Armor, and one of them was the Deuteragonist.
  • Tobi aka Obito Uchiha from Naruto. He's responsible for the deaths of Naruto's parents, Hiruzen's wife, Itachi's teammate, Danzo's bodyguards, Konan, Neji, Shikaku with Inoichi and a large number of allied ninja troops. By claiming Madara's name as an alias, he gains enough clout to force the entire Ninja World into the Fourth World War.
    • Madara Uchiha himself also has a right. He puts both Naruto and Sasuke on their deathbeds in just two chapters. It didn't stick, but that doesn't change the fact that he did it. He also would have possibly killed the five kages if Karin and Suigetsu didn't heal Tsunade.
    • Pain also suitable. He killed one of the most influential mentors to Naruto, Jiraiya, destroyed the Leaf Village, and brought Tsunade to a coma. He also killed numerous named characters, such as Fukasaku and Shizune, led Kakashi to his death, and nearly killed Hinata, though these were reversed with his redemption, save Jiraiya.
    • Hidan is a standout as he not only kills Asuma but he’s one of the few villains who is a complete Jerkass and not in any way redeeming.
    • Orochimaru is the original example of this in Naruto, given that he killed the first Big Good of the series, Hiruzen Sarutobi, the Third Hokage. To be fair, it was via the Third's Heroic Sacrifice, but Sarutobi would've died straight-up if he'd kept fighting normally.
  • Scar from Fullmetal Alchemist is introduced in this fashion. He kills many high ranking state alchemists, and shatters Ed's arm the first time they meet. The Homunculi never lose this title.
    • Wrath/King Bradley. Of all the villains, he has the highest count of characters killed (Dorchet, Roa, Martel, Greed I, Fuu, and Buccaneer, in addition to cutting of Lan Fan's arm, nearly killing Scar, and taking out most of the Briggs garrison and a tank); most people just run after seeing him.
    • In the 2003 anime version (which went in a very different direction from the manga) Scar retains his Hero Killer status for much of the show, and Kimblee, while a different character, still has this going for him. Envy is another very good example, murdering numerous named characters, dancing pirouettes around the heroes during combat, and ultimately killing Ed during the climax. If you see Envy, book it.
  • In Mobile Suit Zeta Gundam not only is Yazan Gable one of the few pilots who can threaten the life of Kamille Bidan, a fact that terrifies Kamille, but by the end of the series he's managed to kill Jamaican Danigan, Katz Kobayashi, Henken Bekkener, the entire crew of the Radish, Emma Sheen, and Reccoa Londe, than opens Mobile Suit Gundam ZZ by cutting down Saegusa.
    • Rakan Dahkaran, the Yazan Gable expy of Mobile Suit Gundam ZZ, naturally also reaches this status. He's one of the few pilots who can regularly give Judau a run for his money, the protagonists typically flee rather than engage him, and he takes out both Mashymyre Cello and longtime Gundam veteran Hayato Kobayashi towards the end of the series.
    • Whenever Ali al-Saachez of Mobile Suit Gundam 00 shows up, you can be sure there will be much asskicking towards the heroes involved. Towards the end of the first season, Ali kills off a total of three named pilots, capping off his killing spree by defeating The Hero of Celestial Being, Lockon Stratos, in mech combat. By the second season, however, Ali al-Saachez has been downgraded from Infinite effectiveness to only High, thank to his first defeat at the hands of his enraged mortal enemy, Setsuna F. Seiei. Eventually, his threat against humanity ended for eternity with his Karmic Death at the hands of the second Lockon Stratos.
  • Lord Darcia from Wolf's Rain becomes this in the final episodes.
  • Anytime Battle Royale's Kazuo Kiriyama shows up, everyone you are rooting for is going to die. Well, with the exception of Sugimura, the only character who is badass enough to survive this encounter. Twice.
  • Pretty much any incarnation of Astro Boy has Pluto, whose entire function is to destroy the most powerful robots on Earth.
  • Kazutaka Muraki from Descendants of Darkness. Literally, by the end of the series.
  • Attack on Titan
    • The Female Titan. While ordinary Titans are quite a problem to deal with, this unique variant proves to be a literal case of More Deadly Than the Male as well as an Implacable Woman. She begins her rampage by slaughtering numerous experienced soldiers, and kills several in unnecessarily cruel ways such as spinning one poor soul to death after she catches his maneuver gear wires. But she's only getting started, and proceeds to slaughter the expert Titan-killers of the Special Operations Squad one by one. In the end, the best the surviving heroes can hope to do is slow her down long enough to escape with their lives. It doesn't help that the real identity of said Titan is Annie who is a very strong warrior up to Mikasa's level and knows exactly how they fight and how their gear works.
    • The Beast Titan gains this status by defeating the 2nd strongest warrior of the Survey Corps when he first shows up. What's more, he was responsible for the emergence of Titans within the Walls. Then in the Battle Of Shiganshina Arc, he took out a large chunk of Survey Corps, including Marlo Sand and Erwin Smith, who had to lead a Heroic Sacrifice charge to distract the Beast Titan until Levi could cut through his defending Titans and then him before escaping with Cart Titan's aid. After the Beast Titan's rampage, coupled with the losses from that of the Colossal Titan, Survey Corps had only nine soldiers left. On top of that, they were forced to choose between letting either Armin or Erwin live on as a Titan shifter. The former was picked.
    • The Colossal Titan is also this in The Battle Of Shiganshina Arc following Bertolt's explosive transformation leading to the deaths of Hange's squad, defeating the Attack/Rogue Titan easily, and then burning Armin alive with his heat. Thankfully Hange and Armin survived but the former loses her eye while the latter had to take the Titan serum and eat the Colossal Titan, Bertolt, in time to live.
    • Gabi Braun, Reiner's cousin, has the distinct honor of having killed 2 major cadets: Sasha and Eren. The former was killed after the attack on Liberio and used as a catalyst for Gabi's Heel Realization. At time of writing, the latter is currently a disembodied head because Gabi shot it off.
  • Neferpitou the first and strongest of the Chimera Ant Royal Guards from Hunter × Hunter. In his debut, Neferpitou killed Kite just to test his strength. Later, he forced Gon to invoke a Deadly Upgrade to defeat him, an act that nearly cost Gon his life.
    • Meryuem, the Chimera Ant King, is the biggest threat that has appeared in the series. Netero dies in their fight.
  • Claymore has Priscilla, who in her debut kills the then-#1 Claymore Teresa and from then on proceeds to walk all over anyone and everyone whenever she gets serious.
    • Rigaldo's very first action is to effortlessly kill numerous named characters during the Northern Campaign (including Jean, Flora and Undine) and forcing Clare to nearly awaken a second time in order to defeat him.
  • Ga-Rei -Zero- has Yomi, who takes the position early by killing the entire cast of the first episode, who were advertised as the main characters, and only gets worse from there.
  • The nine Mass Production Evangelions in End of Evangelion managed to kill Asuka and Unit 02.
    • While Zeruel didn't kill anyone, he provided the biggest curb-stomping in the series up to that point, actually physically breaching NERV headquarters and defeating all three EVAs. It took Unit-01 going berserk, achieving 400% synchronization (causing the pilot to temporarily lose his physical body) and eating Zeruel alive to finally do him in.
  • Rosario + Vampire: Kuyou. In his very first appearance, he immolates Tsukune and very nearly kills Inner Moka; in the case of the former, it's only thanks to a Superhuman Transfusion from Moka that Tsukune didn't stay dead.
  • In Shakugan no Shana, Sabrac is known for having killed nearly every Flame Haze who had ever crossed his path.
  • Ikazuchi, the villain of the second season of Future Card Buddyfight, is the first person to beat Gao, the series' Invincible Hero. He also has his Buddy monster, Yamigedo, eat Tenbu.
  • In Tokyo Ghoul, a pair of these exist to contrast each other and have even clashed with each other during the finale of the original series, until it is revealed that they were secretly working together.
  • X1999 has Fuuma Monou, Kamui's childhood friend and Kotori's brother, who ended up being the "other twin" of Kamui once he chose a side. He's probably the only character with the highest kill count though this only in the anime and movie. In the anime, he killed Kotori, Daisuke, Sorata, Nataku and Kamui while in the movie, he killed Kotori (again), Kusanagi, Yuto, Kanoe, Sorata (again) and Arashi. In the manga, he only killed three people (Kotori, Daisuke and Nataku) so far unless you count destroying the entire Ginza area.
  • In Inuyasha, there is Naraku who slays the monk Miyatsu and the priestess Kikyo (twice).
  • In Future Diary we have the brutal stalker and Deuteragonist Yuno Gasai. The plot of the anime revolves around a game of survival, in the course of which all participants have to kill each other until only one remains. Yuno kills many of them, but most of them are at best anti-heroes, and at worst villains and anti-villains. However, she also kills three good people who are actually heroes, namely Kamado Ueshita, Yomotsu Hirasaka and Akise Aru.
  • During the Marineford War in One Piece Admiral Akainu and Blackbeard gain this status by killing Portgas D. Ace and Whitebeard respectively, shattering One Piece's non flashback named character Plot Armor.
    • Charlotte Oven seems just another mere brute in series full of them so it may comes as surprise to discover he’s first villain to kill a hero since Akainu and Blackbeard pre-timeskip. As Oven beheads his stepfather Pound when latter stopped Oven from trying to capture his daughter and co.
  • Sailor Moon:
    • The Super S part of the first anime was Lighter and Softer until a certain Monster Clown showed up, sent by Zirconia rather than the Amazon Trio. He kills the Amazon Trio as they're on their way to their Heel–Face Turn.
    • Towards the end of the anime, Sailor Galaxia kills Mamoru and Princess Kakyuu.
  • Yu-Gi-Oh! ARC-V has a few characters who fulfill this roll. The Obelisk Force start the trend off during their first phase as Elite Mooks, taking out minor heroic character Michio among a few other non-heroics. During the later arcs B.B also takes out several heroes via carding, among them Tsukikage and Crow and nearly taking out several others. The biggest hero killer of them all however, is Yuri, whose list of victims include Asuka, Yugo and Yusho, between beating and kidnapping many others.
  • In My Hero Academia, Stain is often just referred to as "the Hero Killer" due to the number of professional Heroes who have been murdered or maimed by him (the latter category includes Tensei Iida). He's a Knight Templar who sees most "Heroes" as selfish individuals in it for fame and riches; he'll actually spare those whom he deems truly deserving, including Midoriya, and says that All Might is the only Hero worthy of killing him.
    • All For One makes his entrance during the Hideout Raid arc by blasting away an entire team of heroes without breaking a sweat before blowing a hole through the torso of Rank 4 hero Best Jeanist. He still has enough energy left over to fight All Might to a standstill, and almost succeeds in killing him before All Might gets a Heroic Second Wind and puts All For One down for the count. It's noted later that All For One has killed every previous bearer of One for All (including All Might's mentor Nana Shimura), and as he's been around since Quirks started being a thing he probably has plenty of kills under his belt.
  • One-Punch Man has Garou, a martial artist who targets the Hero Association out of a desire to become a "Monster" in his own right. Subverted, however; it turns out that he never actually kills the heroes he defeated, and his true goal is to be the Big Bad so that there can be a Big Good who can unite the world against him.

    Comic Books 
  • Thanos (pictured above). At one point he literally killed half the population of the universe including many superheroes. At another he literally killed the entire population of the universe including every superhero. In fact, the conflict in Civil War II is caused by him killing War Machine.
  • Doomsday is the ultimate bioengineered killing machine and lived up to that feat by tearing through the JLA and killing Superman. While he's never topped that feat, he remains a deadly threat to all life, everywhere, and his entrance into a story is usually a sign that the bodycount is about to skyrocket.
  • In the Marvel Universe there was The Fury, a robot created by an insane Reality Warper for the express purpose of killing all the heroes of an alternate Earth; it succeeded almost completely.
  • From Spider-Man's universe:
    • Norman Osborn's most well-known murder was that of Gwen Stacy, but he has nearly killed a few super-powered adversaries and did kill Ben Reilly, Peter's clone.
    • Kraven the Hunter's wife Sasha was responsible for the murder of Mattie Franklin (Spider-Woman at the time) and Kaine during the Grim Hunt storyline. (Julia Cornwell, who was going by the name Arachne at the time, was also a target, but was saved by Spider-Man.)
    • And of course, hundreds of Spidey's equivalents from Alternate Universes were killed by the Inheritors during Spider-Verse. You'd need a separate page to list them all.
  • Nitro, the Made of Explodium hitman from Marvel Comics, is notable because he's a low-level C-lister who doesn't even have a nemesis. Yet he is the man who killed the first Captain Marvelnote  and most of the New Warriors, both major events, and in a world where Death Is Cheap, almost all of his kills have stuck.
  • Ultron, in the Marvel Universe, a genocidal robot who has wiped out an entire nation on his own. Massively on his own, in fact; on that occasion, he turned himself into an army. And after he had killed everyone in the country, he turned their corpses into cybernetic combat drones to fight the heroes.
    • Later, he tried to pull the same stunt again, only this time he did it with a galaxy. He also cyber-enslaved a slew of cosmic superheroes - and villains, including the Space Knights of Galador, Gamora (the adopted daughter of Thanos), Drax the Destroyer, Xemnu the Titan, Shatterax, Ronan the Accuser, Nova-Prime and the Super-Adaptoid, several of which qualify as Hero Killers in their own right.
      • And later, he returned in "Avengers" in such a way that the heroes - the most powerful hero team in the world, mind - basically were "Oh, no... not again!"
    • Age of Ultron opens with the unthinkable having already happened. Ultron has managed to conquer the Earth, and in the process, killed off the vast majority of The Avengers, the X-Men, and the Fantastic Four. His victory is all but assured until Wolverine and Sue Storm travel back in time and slam the Reset Button. Hard.
    • And finally, Ultron Forever is set in another timeline where Ultron killed almost every superhero on Earth. Bonus points for wiring up the Avengers' bodies and making them into his personal guard.
  • In the same vein as Galactus, the Celestials also scare the crap out of everyone whenever they show up. Fortunately, they don't go around eating planets left and right. Unfortunately, they have a nasty habit of "judging" worlds they have seeded life on (which is most of them), and executing them if they don't like what they see. Yes, they execute entire planets.
    • The Beyonders are even worse as they managed to kill all of them.
  • In the G.I. Joe Marvel comic book, a SAW Viper misunderstood orders and killed Doc, Thunder, Heavy Metal, and Crankcase. A subsequent vehicle chase led to the deaths of Breaker, Quick Kick, and Crazy Legs. Cobra Commander, who had meant for the Joes to be escorted to the border, was furious at the SAW Viper. The SAW Viper's response? "I just wasted more Joes today than your entire legions have accounted for in nine years!" Cobra Commander throws him a party in response.
  • The Anti-Monitor, who personally beat Supergirl to death, after having already eaten hundreds of universes, and went on to be responsible for a scad of other hero deaths. He's the standard by which DCU characters judge "evil" and "dangerous". In a mostly successful attempt to avoid Villain Decay, DC only used him three (and a half) times from 1985 to 2010, a full quarter century.
  • DC has tried to do this with Deathstroke. For the past few years he's been pushed as one of the top villains of the DCU, on par with Lex Luthor and The Joker. He actually has managed to kill a couple of heroes, including Phantom Lady and the third Atom (and in the trailer for DC Universe Online, he almost kills Batman). Unfortunately, while his powerset (he's basically an evil Captain America with a healing factor thrown in/Deadpool with sanity) should make him utterly terrifying to normals and low-level metas, it's a little more difficult to accept him as a serious threat to the likes of Superman and Green Lantern. His victories against big-name heroes tend to depend on his opponent firmly grasping the Idiot Ball and refusing to let it go (e.g. Flash running straight onto his sword; Green Lantern deciding to swing punches at him instead of flying off and using a ring construct from a distance; or Superman apparently forgetting how his own powers work). Fans have joked that Deathstroke's secret power is a "jobber aura" that makes his opponents behave like morons.
    • To rub salt in the wound, originally Slade was savvy enough to AVOID facing superhumans. He just faced the Titans to complete the contract his deceased son had accepted.
    • Also as of the New 52, The Atom, his highest-profile kill, is alive again.
  • Willy Pete, of Empowered, is a particularly nightmarish version. His name is a military term for white phosphorous, and his powers match the name. He's capable of causing an impact as powerful as a nuclear explosion, and generating fire that reaches temperatures as hot as the sun. His favorite pastime is skull-fucking people to death as he eats them, not always in that order, and not always before they're dead. Being a fire elemental, he doesn't need to eat. He just likes to. He specifically goes after Made of Iron superhumans because anything less turns to ash at his touch before he gets any enjoyment out of it. He goes out of his way to only kill D-List heroes and villains, not because he's weak, but because it makes people underestimate him. He likes being underestimated, as it makes people think he's a pushover until it's too late (and he can make it too late pretty damn fast). He's the recurring nightmare of Thug Boy, due to killing all of his friends. In Volume 5, he kills eight and a half capes in an instant, and then proceeds to destroy most of the d10, the Superhomeys' space station. He doesn't try for an instant during all of this. He's just that powerful. It's probably fair to say he won't be getting many people to underestimate him any more after that.
    • In volume six, they introduced another hero killer, Deathmonger - a superscience necromancer who has enslaved legions of dead heroes. All the supers are too scared to go after him, for fear of adding to his ranks. He's still not as frightening as Willy Pete. Wasn't this supposed to be a "sexy superhero comedy"?
  • Wonder Woman
    • Wonder Woman (2006) foe Genocide was created with this in mind. The Secret Society engineered this monster to take out the superhero community.
    • Wonder Woman herself has actually been killed by a villain twice. The first instance was during the War of the Gods event in which Circe devolved Diana back into the clay from which she was made. The second was when she was killed by the demon lord Neron during the Hell To Pay event in Wonder Woman Vol 2.
    • In volume 2 Hippolyta hosting The Contest in order to replace Diana as Wonder Woman after learning that Wonder Woman is fated to die soon leads to Artemis's brutal death as Wonder Woman at the White Magician's hands.
  • In the Archie Comics' Sonic the Hedgehog, the current Eggman (actually an alternate version of the first one), was this, managing to kill his version of Sonic and the Freedom Fighters, and when he first made his big return he conquered Mobotropolis and forced the Mobians to retreat back to Knothole, effectively resetting the series status quo to before Robotnik Prime died, though since then he's gone back and forth between how much a threat he posed. A more extreme case is the alternate timeline where Knuckles became a new Enerjak. He became so powerful that he single handily conquered Mobius and defeated every hero and villain that tried to stop him, even Sonic becoming Super Sonic wasn't enough to stop him. Pretty much the only reason why the Freedom Fighters are around in his timeline when Silver shows up there is because he let the Freedom fighters roam around for his amusement.
  • From the Transformers franchise, we have Bludgeon, a literal Ninja Pirate Zombie Robot. (Seriously, he would have been a pirate in Transformers Animated) In most of his appearances, he's one of the most lethal Decepticon warriors - in the Marvel G1 comics, he eventually ascended to the position of Decepticon leader, and only lost because of The Last Autobot. In the IDW comics, he beat down fan-favorite Soundwave and his casette bots after his own minions, Iguanus and Bomb-Burst, were dispatched. In the Titan UK comics, his Movieverse incarnation is one of only TWO characters to be shown killing his enemies on-panel.
  • In Spider-Girl Roderick Kingsley, the original Hobgoblin, becomes this after coming out of retirement. He effortlessly beats down Spider-Girl and her allies with minimal help, kills the Venom symbiote, wrecks Black Tarantula's organisation, and gets away.
  • Durge in the Star Wars: Clone Wars comics and the television show. The most prolific slaugtherer of Jedi prior to Grievous' arrival, Durge killed god knows how many named characters, came frighteningly close to murdering Anakin and Obi-Wan on several occasions, and had to be fired into the freaking sun before he finally went down.
  • Anathos from Les Légendaires. His backstory involves him successfully destroying the world, with the other Gods failing to stop him (he was only defeated because the weapon he was using eventually escaped to his control and explode in his hand). The news of his incoming return inspires so much fear that it lead the usually Lawful Neutral Guardian to resurrect the Big Bad and Good Twin and order her to team up in order to stop his return (which they agree to do). When he finally shows up, he reincarnates in The Hero, proceeds to deliver the most No-Holds-Barred Beatdown of the whole series on the other protagonists (including Eye Scream for one of them), then kills the Guardian and his allies. While he was defeated later, his arc ended up putting the whole story in a Nothing Is the Same Anymore situation.
  • The Governor; Rick and his group are terrified of him, and whenever he shows up, there is a good chance people will die. He's responsible for the deaths of Axel, Billy, Lori, and Judith. In addition, he personally kills Tyreese, Hershel, Patricia, and Alice, and cuts off Rick's right hand.]
    • Negan marks his first appearance by bashing Glenn's skull in with a baseball bat coated in barbed wire.
  • The Transformers: Last Stand of the Wreckers: While Phase Sixers are theoretically this (Black Shadow's kills were high, but only showed right before he gets Worfed, and Sixshot, while threatening, never really brings the threat of main character death to the stage), Overlord stands above them. From his very first appearance both Autobots and Decepticons fear him, and when he shows up, people die, by the end of the series, he's killed or ordered the deaths of over 60 bots including Skyquake, Kick-off, Wingblazer, Rotorstorm, and Spin-out. His reappearance in The Transformers: More Than Meets the Eye continues this trend, even with all of his weapons gone, he still levels the crew and is responsible for six deaths.
  • Subverted with Adrian Veidt of Watchmen, whose murder of the Comedian sets the plot in motion. He is not a "Hero" not even nominally.
  • Invincible: Robot attempts to kill the vast majority of the world's superheroes to help his takeover of the world go smoothly. He succeeds.
  • Warren Ellis used the Xenomorphs for this role in the Wild CATS/Alien crossover he wrote, killing off the Stormwatch characters he wasn't going to use for The Authority
  • Deadpool in Deadpool Kills the Marvel Universe, guess who kills him Deadpool.
  • Onomatopaeia is a downplayed example, targeting Badass Normal heroes like Green Arrow and Batman, and staying away from genuinely empowered foes.
  • Superboy-Prime, who during Infinite Crisis killed roughly a dozen named superheroes. Ironically, he also resurrected many superheroes when he punched the barrier of reality.
  • In Doomsday Clock, Doctor Manhattan killed Alan Scott by changing the past and erased the Legion of Superheroes from the future though in the end, he reversed these. In DC Universe Rebirth #1, which set the stage for Doomsday Clock, he killed Pandora by vapourizing her.
  • Captain America villain Crossbones is one for the Badass Normal set, having ratcheted up a fair bodycount over the course of his career. He's also the one who fired the shot that killed Cap at the end of Civil War firmly cementing his reputation as one of these.
  • Ultimate Marvel:
    • Among the deaths caused by Magneto during the tidal wave that Ultimatum opens on are Angel, Beast, and Dazzler. Following issues also sees Magneto personally kill Professor Xavier and Wolverine.
  • For street-level characters in the DC universe, Lady Shiva dropping into your life is pretty much guaranteed to end in someone's death. Though she's rather unpredictable, and has even saved heroes on occasion, she's also been responsible for the (admittedly temporary) deaths of Batgirl, The Question, and Richard Dragon, among many less prominent characters. She's also come within seconds of killing Huntress and Connor Hawke (the second Green Arrow), and beaten the tar out of Catwoman, Nightwing, Robin note  and even Batman himself.
  • In Mighty Morphin' Power Rangers (Boom! Studios), we have Lord Drakkon, the evil version of Tommy Oliver from a universe where he stayed by Rita's side even after being freed from the Sword of Darkness. In his timeline, he killed Jason, Billy, Alpha 5, Ninjor, the Alien Rangers and the Phantom Ranger. In Mighty Morphin' Power Rangers: Shattered Grid, he added to that list, so far, with most of the Time Force Power Rangers and, most surprisingly, the heroic Tommy Oliver.
  • The Joker's most infamous kill is the second Robin Jason Todd. This is such a sore spot for the Bat-Family (even after Jason's resurrection thanks to said Superboy-Prime) that when one event made it seem that Killer Croc, let loose by the Joker, had eaten the third Robin Tim Drake, Nightwing beat the Joker to death, Batman having to resuscitate him to make sure Dick didn't have that on his conscience, especially since Tim was alive.
  • While Solomon Grundy is often remembered for his usual third person speaking pattern he is a dangerous and unpredictable threat, in both terms of personality and the strength of his powers and has killed some heroes who have stayed dead through several universe reboots such as Skyman, who is better known by his Kid Hero name as the Star-Spangled Kid.

    Fan Works 
  • The Powers of Harmony: Cetus and Eclipse are both this. They're able to take on Shining Armor and the Princesses evenly, and curbstomp the Mane Six and their Guards including killing Strauss, Elo and Grovi.
  • Harmony Theory: Max Cash the Magnificent Bastard of the Big Bad Ensemble, personally kills Melody Drop, a former body guard who was out for Revenge, after he destroyed her old life, during her attempted Big Damn Heroes.
  • The Azula Trilogy has Wei Ming and Jian Chin (when possessed by Zhang Zhen). Ironically, they were designed to be this role to Azula, who as noted below in Western Animation, is herself one of these.
  • Sben of Yognapped becomes this once he's resurrected.
  • In Mega Man: Defender of the Human Race, Bass inspires fear in Mega Man, and manages to give both him and ProtoMan a good thrashing before barely losing or leaving due to outside circumstances.
    • Wily later builds Enker, Punk, and Ballade, the Mega Man Killers. They live up to their name; in-fighting is the only reason they don't succeed in their first encounter with Mega Man.
    • Later those two forces fight. Bass wins, and Mega Man is even more afraid.
  • In The Immortal Game, one of the first things King Titan does is to kill Princess Celestia. Actually he just beats her within an inch of her life and gives her to Terra to torture, but he could full well have killed her. He is such a terrifying force that even his Puppet Avatars are enough to dominate Princess Luna.
  • In My Brave Pony: Star Fleet Magic III, Raven is ultimately the one to kill Twilight Sparkle.
  • In Digimon Fusion Kai, Frieza's expy Burizalor has killed Falcomon, Izzy, Matt and Sora near the end of the Spira arc.
  • Evan when dealing with real heavy hitters like ADAM, every fight against an Angel on Nobody Dies had been a cavalcade of craziness for various "seasons" (an example being a many-enemy-Evas-against-a-heroic-one situation similar to The End Of Evangelion becoming a re-enactment of the Burly Brawl). So how do the Cherubim establish that they are the Knight of Cerebus team? By having the very first one that appears take on various Evangelions at the same time and win even with them using Super Mode, killing Shinji for a few seconds and nearly destroying Unit-01's core. It took the uncontrolled activation of Unit-01's Berserk Mode for NERV to win the fight... and the repercussions were still pretty hefty.

    Films — Animation 

    Films — Live-Action 
  • The titular Alien was a Meta-Example, as well as an In-Universe one: originally, Dallas was scripted to be the film's protagonist; most of the audience concurred - thanks to clever writing, first-billing in cast order, and camera shots - up til the product film's midpoint when he was Killed Offscreen and Eaten Alive by the Xenomorph. In-Universe, it claimed the lives of all crew except the film's true protagonist - Ellen Ripley.
  • In Bodyguards And Assassins the final assassin is a highly skilled martial artist before whom all the bodyguards, all capable fighters in their own right, can only desperately throw themselves in his way in an attempt to buy time.
  • The Dark Knight has a straight version of this trope in the form of The Joker. He outright murders former GCPD officer Brian Douglas (one of the vigilantes wearing a Batman costume), kills several known Gotham City cops and other law enforcement including Commissioner Loeb and Rachel Dawes, and finally causes Dent to slide off the slope of sanity, leading to several more deaths, including Dent's own.
  • Eragon has Durza. Alongside his original deeds in the books of hastening Eragon's journey by poisoning Arya, he takes the Ra'zac's role of the character that kills Brom, slaughters dozens of Varden soldiers, and creates a Giant Flyer made out of smoke that grievously wounds Saphira.
  • In the Godzilla franchise, a Kaiju's badass rating is generally measured by how long it can last against Godzilla and how much trouble it can give the King of the Monsters before dying. With that in mind, the few monsters who have actually taken down Godzilla, to any degree, get a special mention.
    • King Ghidorah normally comes close, but never quite manages to defeat Godzilla. Mecha-King Ghidorah, however, managed to fight Big G to a Mutual Kill.
    • Destoroyah is the living personification of the Oxygen Destroyer, the weapon that killed the original Godzilla, In its first appearance as a kaiju, it killed Godzilla Jr., and in Rulers of Earth, managed to knock Godzilla unconscious in a one-on-one fight.
    • The Heisei Mechagodzilla goes above and beyond by defeating both Godzilla and Rodan together. Only Rodan's Heroic Sacrifice allowed Godzilla to return to life with enough power to finally defeat his mechanical opposite.
  • In Highlander, the Kurgan hunts other immortals to steal their power. All of the immortals are potential hero killers, but the Kurgan stands out among them.
  • The Velociraptors of Jurassic Park are a rare animalian, reptilian example. They flirt their Protagonist-murdering potential within the first five minutes of the film after they rip a full-grown man from the grip of the Park's Warden and tear him to shreds inside their pen. This potential matures by the film's Third Act, as, at this point, all three of them have escaped their pen and have begun offing humans - for territorial reasons, for competitive reasons, for hunger, or for one or two or all of those reasons. The first person to be preyed and eaten is Mr. Arnold in the basement, but by far the most frightening execution is that of Robert Muldoon - he who knew their nature better than anyone.
  • The Harpists in Kung Fu Hustle, who kill off Coolie, Tailor and Donut after the three prove themselves to be Pig Sty Alley's resident badasses (and forcing the Landlord and Landlady to drop their Crouching Moron, Hidden Badass facades to take them down.)
  • Magua from Last of the Mohicans. Aside from being a powerful, skilled leader, (he's the only one who lasts more than several seconds against the film's main characters), he personally kills Uncas and is indirectly responsible for the death of Alice, who chooses to fall to her death after Magua kills Uncas.
  • Marvel Cinematic Universe
  • The Matrix: The Agents are designed to stop and kill members of the resistance and have superhuman abilities in the Matrix far beyond even what the enlightened humans can achieve by "hacking" it. They have superior Super Strength as well as Super Reflexes that allow them to almost always Dodge the Bullet, and are Nigh Invulnerable. Besides of this, they're not programmed to actually die even if you kill their current body. You may be able to run from them, but no-one can fight one. This is also a plot point in that only The One could possibly hope to beat an Agent.
  • No Country for Old Men: Anton Chigurh, whose participation in the plot accounts single-handedly for almost every terrifying moment in the film. One example: he hides in the bathroom of a crime scene with a loaded shotgun as Detective Bell despondently investigates the complex.
  • Part of Rita Repulsa's Adaptational Badassery in Power Rangers (2017) involved being a member of a past team of Power Rangers that she turned on and wiped out but for Zordon, who, in the face of defeat, chose to call a meteor down on his own location and try to catch her in the blast radius. The fact that she was strong enough to take down a full Ranger team on her own increases the urgency of the new team's training when she re-emerges, as Zordon's surviving consciousness is perfectly aware of what she's capable of and knows the new Rangers have to be as strong as possible to survive against her, let alone stop her from conquering the world.
  • Star Wars:
    • Darth Vader. In the first film, he kills Obi-Wan Kenobi in a lightsaber duel and shoots down numerous Rebel pilots during their assault on the Death Star, including two squadron leaders and Luke's friend Biggs, along with dealing R2-D2 serious damage. In the second, he cuts off Luke's hand and has Han Solo suspended in carbonite. In the prequels, he double teams Mace Windu with Palpatine and slaughters a whole class of youngling Jedi. In Rogue One we get to see him do some heavy-duty Darth Vadering on a ship as he effortlessly shreds his way through an entire squad of Rebels in a moment that is made of awesome and downright chilling. In the expanded universe he hunts down and defeats numerous Jedi as well.
    • In The Force Awakens, Kylo Ren has this reputation among the First Order as he was responsible for the destruction of the new Jedi Order. He later earns it in full when he kills his father, Han Solo, showing that he's even more evil than Vader, as Vader couldn't bring himself to kill a member of his own family. The film also ends with Finn in a coma after Ren nearly kills him.
    • In Rogue One, the Death Troopers demonstrate that these stormtroopers are not to be fucked with by killing Lyra Erso, Chirrut Imwe, and Baze Malbus and non-fatally shooting Cassian Andor. Not to mention the scores of Rebel redshirts whom they chew up like lawnmowers.
  • The various Terminators were created for this purpose, but only the T-800 in Terminator: Dark Fate was successful in killing John Connor whereas the original T-800 sent back to kill Sarah (though he did kill Kyle Reese) and the T-1000 failed. The T-850 also killed John in the future before being reprogrammed and sent back to protect him and Kate, and the T-5000 turned John into a T-3000.
  • X-Men Film Series
    • In X-Men Origins: Wolverine, Victor Creed murders about 80% of the cast. His resume includes: Wolverine's Only Friend John Wraith, Wade Wilson (though Stryker somewhat brings him back brainwashed), Silverfox twice, Bradley and finally Blob (at least that's what's implied by his dialogue with Wraith). Meaning the only main cast members he never killed were Wolverine, Gambit, Agent Zero and Stryker.
    • In X-Men: Days of Future Past, Future Sentinels are downright unstoppable; even a combined team of half-a-dozen really powerful mutants can't defeat them. They kill most of the characters in the Bad Future, some of them more than once, and the only way to escape from them is to run before they even find you. Plus the only way to stop them completely is to retcon them out of existence, as the X-Men's plan is to Set Right What Once Went Wrong.
    • In Logan there’s X-24 the titular Anti-Hero’s Evil Twin who kills Charles Xavier and kills Wolverine himself in the final fight. Technically Dr. Zander Rice also counts as thanks to him all mutants are now extinct, thankfully Wolverine guns him down before dying himself.
  • Von Ryan's Express: Gortz is a ruthless and taciturn SS officer. He commands a detachment of crack troops whose sole purpose in the story is to hunt down the American and British airmen who got out of the Fascist Italian P.O.W. camp - and either recapture them or kill them. American officer "Von" Ryan and his British counterpart and Vitriolic Best Bud Fincham hold off the Nazis before running for the train as it crosses into Switzerland. In a fit of Tranquil Fury, Gortz grabs a gun from one of his men and shoots Ryan in the back just before he gets aboard as a parting shot to his escaping prey.

  • More than a dozen show up across The Black Company. The first book has the Ten Who Were Taken, plus the Lady and the Dominator, with the Shadowmasters and the Voroshk turning up later. Of particular note:
    • The Limper kills literally thousands of extras, as well as Bomanz and Silent.
    • Shapeshifter killed Tom-Tom at the start of the series.
    • The Dominator kills so many Company Brothers that the book ends with the Company's roster at seven members.
    • Lisa Bowalk finally kills One-Eye for his involvement in her mentor, Shapeshifter's, death, after more than twenty years of feuding.
    • The Goddess Kina Herself kills Goblin personally and millions of others by proxy.
  • An interesting in-universe example occurs in Anthony Ryan's novel Blood Song. The protagonist, Vaelin al Sorna, kills another country's champion during an invasion and is subsequently dubbed "Hope Killer" (the guy he killed was the avatar of hope for the entire nation) by the enemy.
  • The Dresden Files: Nicodemus Archleone. He has killed at least a hundred Knights of the Cross and only two have ever gotten away with their lives, and of those, one was permanently crippled.
    • The one who escaped without being permanently crippled so angered Nicodemus that even after Nicodemus had him tortured to death Nicodemus was willing to give the good guys a chance to stop his plan to turn the Archive (a repository of all humanities knowledge, and thus possessor of the launch codes to every nuke on earth among other things) into a Denarian just to get the guy's sword, Fidelacchius.
  • Fate of the Forty Sixth: The forces employed by Apex are deadly and really show why Apex is the best. Condor effortlessly defeats Wolf twice, only leaving him alive because his contract says so and he doesn't what to kill off a good opponent with potential. The Justice, an extremely dangerous mech with six barrels filled with shotgun shells, and its pilot, Victory, claim the lives of Andre, Caruso and Red. And finally, the nameless dragon at the end kills Bob, Filch, Murray, Ry and Blaze with Baron, another dragon, finishes off Roy.
  • The First Law trilogy contains the aptly named Fenris the Feared. After radiating menace before the Open Council in The Blade Itself, he proves his status as a member of this trope toward the end of Before They Are Hanged, killing one of the most heroic characters in the series, Rudd Threetrees.
  • Harry Potter:
    • If you are face to face with Lord Voldemort and your name isn't Albus Dumbledore (who is the one who HE fears), you either run like hell or kiss your butt goodbye. Let's just say that people are afraid to say his name for a reason. To quote Hagrid when he starts telling Harry about Voldemort:
    "Nobody lived once he decided to kill 'em. No one except you! And he killed some of the best witches and wizards of the age. The McKinnons! The Bones! The Prewetts! And you was only a baby, and you lived."
    • Bellatrix Lestrange later became a Dragon form of this with several significant deaths (Sirius, Dobby and Tonks (according to Word of God)) under her belt before she was taken out. Considering that she's one of the vilest characters in the series, this isn't much of a surprise.
    • A lesser one can be found with Antonin Dolohov, one of Voldemort's tougher underlings. In the first war, he was the Death Eater who slew Gideon and Fabian Prewett, who were both powerful and accomplished wizards. In the second, he seriously injured Mad-Eye Moody and almost kills Hermione in Order of the Phoenix and is, according to Word of God, the person who slew Lupin in Deathly Hallows. He also goes up against Harry, Ron and Hermione all by himself after his partner Thorfin was stunned in a cafe and subdues both Harry and Ron before Hermione body-binds him.
  • Inheritance Cycle: Murtagh starts entering this role in the second book, especially at the climax, where he slaughters the dwarf king and his magician bodyguards with a single spell before soundly trashing Eragon and Saphira, but letting them go in a moment of mercy.
  • In the Malazan Book of the Fallen Kallor's first big hit is Whiskeyjack in Memories of Ice. Then he returns in Toll the Hounds with the intention to 'get himself a throne', whoever stands in his way be damned. When Spinnock does stand in his way, he almost gets to cross the next hero off his kill list.
  • The Lord Ruler from Mistborn, figuratively and literally, as he takes down Kelsier effortlessly immediately after the latter has his Moment of Awesome by killing an Inquisitor. Ruin is this trope even moreso.
  • In The Mortal Instruments, Jonathan Morgenstern plays the trope straight. He kills some shadowhunters. One of the first victims is the shadowhunter Sebastian Verlac. Later, he kills Max Lightwood and Hodge Starkweather. But he also kills vampires and werewolves, who are the allies of the shadowhunters. Two of his victims are Raphael Santiago and Jordan Kyle.
    • The prequel The Infernal Devices has the demon Marbas who kills a female shadowhunter named Ella Herondale.
    • And the sequel The Dark Artifices has the evil warlock Malcolm Fade. He kills two shadowhunters named John Carstairs and Cordelia Townsend.
  • Night Watch: The Mirror from Day Watch, who killed Tiger Cub by literally stripping her flesh from her bones after incapacitating several other high-level Night Watch magicians.
  • Old Kingdom: Kerrigor in Sabriel is the most powerful Greater Dead in the history of the Old Kingdom and has spent the last several centuries waging a war of attrition against the Abhorsens, the lineage of necromancers tasked with laying the undead to rest. He spent most of that time winning because he'd turned his mortal body into a Soul Jar so that he could never be fully banished while it existed and hidden it very well, and also wiped out the royal family except for one member and threw the Kingdom into chaos while he was at it. In the end, he's defeated only after a grueling battle that nearly kills Sabriel and Touchstone and even then, he's only turned into a Sealed Evil in a Can, not destroyed.
  • The Pirates Covered in Fur has the main villain, Captain Lyle Krinkor. Not including the Decoy Protagonist, he single-handedly kills four of the main protagonists—three of whom are killed in one chapter. And if he hadn't been playing with the Villain Ball, he would've killed five by the time the story wrapped up.
  • Romance of the Three Kingdoms: Lu Bu, the baddest ass in a World of Badass. The big three heroes duel him all at the same time and are unable to defeat him. Ultimately they have to kill him with a Honey Trap.
  • In The Saga of Darren Shan is the vampaneze Glalda. He attacks with his group of vampanezes to an army of vampires (vampires are in these books not bad). In the fight he kills several vampires (two in the books, three in the manga), and thereafter the female vampire Arra Sails.
    • Furthermore, since even the traitor Kurda Smalth. He kills the vampire Gavner Purl.
    • The main antagonist, Steve Leopard is very nasty and a half-vampaneze. He kills indirectly Larten Crepsley.
  • The Silmarillion: Gothmog only ever seems to appear when there is an Elf-Lord to kill. Under his belt are Fëanor, Fingon and Ecthelion, all badass warriorsin their own right, though the last one was far from a Curbstomp Battle. His master Morgoth gets in on the fun by killing Finwë and Fingolfin. Finally Sauron deserves an honorable mentionfor killing Gil-Galad and the Dunedain king Elendil during the same battle.
  • Star Wars Legends: In New Jedi Order, The Yuuzhan Vong basically have this (with a healthy dose of Combat Sadomasochist on the side) as their hat. Even among the Yuuzhan Vong, the voxyn are notorious for this. They're introduced casually hunting down several Jedi and only go up from there. The mission to kill the voxyn queen has the single largest Mauve Shirt casualty count in the series and kills no less a hero than Anakin Solo.
  • The Sword of Truth has some examples. The Dreamwalker, a weapon from the Great War, has power over someone directly proportional to their magical talent, with a few exceptions. He can brutally mind-rape (in every possible sense of the expression) sorceresses and (off-screen wizards), but he can barely touch any of the muggles (who all have some tiny amount of magical power anyway, only a few people in the world are truly devoid of any magic at all).

    Live-Action TV 
  • Buffy the Vampire Slayer:
    • Spike himself has personally killed two Slayers, a fact he takes much pride in even after his Heel–Face Turn.
    • Glory. The Scoobies spend the entire season running from her in terror. And her actions indirectly lead to Buffy's death in the Season 5 finale.
      • Almost an entire season running in terror. Glory's Mind Rape of Tara is what initiated Willow's first Roaring Rampage of Revenge. But the Scoobies still have to plan out literally every single step they take during the final battle with the Hell-bitch (the overall strategy of which amounts to "desperately try to keep her busy without getting killed for a few minutes").
    • Vampire Xander kills Wishverse Angel.
    • The Master kills Buffy herself. Twice, once in the real world, and once in the Wishverse. And supplementary materials reveal that in the past he's killed one Slayer and sired another.
    • Warren fatally shoots Tara and comes impressively close to killing Buffy herself.
    • The Angelus kills Jenny Calendar, and his actions indirectly lead to the death of regular Angel.
    • Drusilla killing two slayers - first Kendra and later Marianne.
    • Caleb. A fanatical, woman-hating defrocked preacher serving as The First Evil's right hand man. In his debut, a trap he laid for Buffy's friends at the Shadow Valley Vineyard in Season 7's "Dirty Girls", his rampage ends up killing two Potential Slayers- Molly and an unnamed Potential. He also knocks out Buffy with one punch, overpowers Faith and Spike easily, breaks Rona's arm, and most infamously, gouges out Xander's eye with only his thumb, maiming one of the Scooby Gang's core members. It would take the combined efforts of both Buffy AND Angel to defeat him in later episodes.
    • Cyvus Vail, a demonic warlock, kills Wesley Wyndam-Pryce.
    • Nash and Pearl are two half-demons who are very strong and very nasty. They kill in the battles against the protagonists, the three slayers Saabira, Cori and Vanessa. Later, in London, they kill a whole group of other slayers.
    • Even Harmony has one to her credit, killing Soledad. (Of course, it was mostly Soledad's fault, but the act did make Harmony a legit threat for quite a while, as it caused the a lot of negative PR for Buffy's group.)
  • Sylar from Heroes, who besides being one of the most powerful characters in the show's mythology has also racked up by far the highest number of main character and supporting character kills.
  • Robin Hood Played straight with Isabella, who deals a mortal blow to her brother, Guy of Gisborne, after his Heel–Face Turn and poisons Robin himself.
  • John from The Fades. Before the other characters learn his name, he's known as the Angelic Killer because he's racked up such a high body count. In fact, he's responsible for the deaths of multiple major characters before the end of the first episode.
  • Supernatural:
    • The demon Meg is an example of this trope. In Season One alone she was able to come dangerously close to killing Sam, Dean, and John, kill two hunters, and captured John. Next season she killed another hunter and almost succeeded in killing Dean and Jo. She was later responsible for the deaths of Ellen and Jo. It is also worth noting that she was the first demon to successfully defeat an angel.
    • Azazel also has killed his share of hunters, most obviously Mary Winchester and everyone who knew her. He also killed John twice, and has indirectly killed both Sam and Dean temporarily. In fact, since it was because of his influence that Sam got the power to kill Lilith and free Lucifer, he's also indirectly responsible for the deaths of Ellen and Jo, and the temporary deaths of Bobby and Castiel.
    • Also, Abaddon, who in her first appearance singlehandedly slaughtered the entire Men of Letters.
    • In "The End", Lucifer crushes the head of a future version of Dean Winchester. In "Swan Song", Lucifer blows Castiel to smithereens with the snap of his fingers, telekinetically breaks Bobby's neck, and in order to defeat him, Sam is forced to sacrifice himself by jumping in the Cage.
    • Dick Roman introduces himself as this in his first appearance when he and his Leviathans tear Castiel apart from the inside out. This is temporary, but he does end up permanently killing both Frank Devereaux and Bobby Singer. In the S7 finale, the explosion created by his death drags both Dean and Castiel to Purgatory.
  • The first villain in Bones to off one of the heroes was Jacob Broadsky. He wanted to kill Booth, but he was aiming by calling Booth on the phone and aiming at whoever held the other end - which, since Booth had passed the phone off to run a trace, was Vincent Nigel-Murray.
  • Kaiju in the Ultra Series that kill an Ultraman (or at least defeat them) in their debut series typically become notorious among fans and make many reappearances for this. The two greatest Hero Killers though are:
  • Grant Ward in Agents of S.H.I.E.L.D.. Out of all the villains, he's responsible for killing the most named characters on the show, including Victoria Hand, Eric Koenig, and (spoilers for Season 3) Rosalind Price. He also inflicted an agonizing Cold-Blooded Torture on Bobbi and while he didn't kill her, he almost broke her morale for the job.
  • Game of Thrones:
    • Ramsay Snow/Bolton outdoes his already terrifying book version, starting off by doing much worse to Theon Greyjoy than just killing him. He then nearly gets Theon's Action Girl sister in season 4 (despite Ramsay being half-naked, ambushed and post-coital at the time), and personally smashes King Stannis' army in season 5. He becomes this trope in S6, though, when he remorselessly kills his own father, stepmother and newborn baby brother. A couple of episodes later, he easily dispatches fan favourite Osha too. This is followed by killing Rickon Stark and Wun-Wun the giant in the Battle of the Bastards. His kill count of unnamed characters is through the roof, and that's not even counting his offscreen destruction of the main characters' childhood home.
    • Ser Gregor “The Mountain” Clegane is the strongest man in the Seven Kingdoms and is deadly, bloodthirsty and widely feared for it by other heavy hitters. He is notorious for raping and killing Elia Martell and her children during the Sack of King’s Landing. He’s also responsible for maiming and killing Ser Beric Dondarrion though he got better thanks to Thoros of Myr and slaying Ser Hugh of the Vale in a tournament. When Elia’s brother, Oberyn, dueled him in a Trial by Combat and nearly bested him, Gregor got the advantage to bring him down and crushed his head. However, Gregor ended up braindead by Oberyn’s poison so Qyburn turned him into some Humanoid Abomination who became Cersei’s loyal bodyguard. In Season 8, he beheads Daenerys' close adviser, Missandei, and nearly kills his own brother, Sandor, by attempting to crush his head but Sandor stabs him in the eye and pushed him off the Red Keep along with himself.
    • The White Walkers and their army of the wights, led by the Night’s King. At the start of the series, they demonstrate their dreadedness by killing two Night’s Watch rangers and turning them into wights. Later on, they raid Hardhome and slaughter many wildings. In Season 6, they kill several Children of the Forest ,Bran’s direwolf Summer, and Hodor with the Night’s King personally killing the Three-Eyed Raven. And by the end of Season 6, winter has finally come and the army of the dead marches south, ready to take out whatever’s left of the main cast. In Season 7, the Night King delivers a One-Hit Kill on Viserion, one of Daenerys' dragons and destroys the entire Eastwatch castle with the use of the undead Viserion so that his army of the dead can finally match towards the Seven Kingdoms. In Season 8, while they're finally stopped at Winterfell, they kill Dolorous Edd, Lyanna Mormont, Beric Dondarrion and Jorah Mormont before being defeated, with the Night King personally killing Theon Greyjoy before going down.
    • Euron Greyjoy is a terror in battle and, while "hero" is probably the last word most people think of for some of his kills, he still manages to murder Balon effortlessly, slay Obara and Nym in battle, and defeat his badass niece, Yara, in combat, resulting in him taking her hostage. He also kills Daenerys's other dragon, Rhaegal, with a scorpion ballista and fatally stabs Jaime.
  • In the series Primeval anyone can be killed. In most cases this is by a predator from prehistoric times (or from the future). However, there is also Helen Cutter, who became an antagonist over the course of the series, and kills her husband Nick Cutter and is indirectly to blame for Stephen Hart's death.
  • A few antagonists in The Walking Dead have managed to kill or at least be responsible for the deaths of multiple characters, some more prominent than others:
    • The Governor personally kills Axel, Merle, Milton, and Hershel and causes the death of Andrea.
    • Officer Dawn Lerner, while not around for as long as any of the other antagonists, does deal a crippling blow to the morale of Rick's group by murdering Beth via Boom, Headshot!.
    • Negan makes his introduction offing both Abraham and Glenn.
    • Alpha shows she means business by decapitating ten survivors from the various Washington communities and placing their heads on pikes for all to see. Among the casualties are major characters Tara and Enid as well as Carol's son, Henry.
    • Beta murders reformed Whisperer Gamma and ex-Savior Laura.
    • Undercover Whisperer Dante strangles Siddiq to death.
  • Wonder Woman: The Zardor in "Mind Stealers from Outer Space". It was a large, nearly mindless humanoid monster that the Skrill only kept with them for the few threats that they couldn't overwhelm with their laser weapons or mind-stealing technology. He was a serious threat to Wonder Woman.
  • Though this trope in Super Sentai is somewhat common, it's a massive shock when it happens in Power Rangers. So far, the only real major Hero Killer is Psycho Pink from Power Rangers in Space, who murdered the original Lost Galaxy Pink Ranger Kendrix Morgan.

    Myths & Religion 
  • Norse Mythology:
    • Fenrir and Jormungandr are likely the two best examples, as they are feared long before the apocalypse goes down, have established rivalries with the gods, and take the two strongest gods (Odin and Thor) with them when they go.
    • Surtr is more or less described as one in the mythos proper: "At the end of the world he will go and wage war and defeat all the gods and burn the whole world with fire." He also personally kills Frey in the process.

    Pro Wrestling 
  • Ivan Koloff: In 1971, the "Russian Bear" did what few people thought possible: defeat then-unbeatable WWWF World Champion Bruno Sammartino cleanly, in the center of the ring, on his home turf at New York City's Madison Square Garden. Koloff completely dominated the match and, after knocking the Living Legend down with a clothesline, dropped the top-rope knee on his prone body. Surprisingly, an exhausted Sammartino never attempted to lift his shoulders. The crowd sat in stunned silence as Koloff celebrated in the ring with his manager, the evil Captain Lou Albano … and rumor had it that an announcement that Koloff was the new champion was never made for fear of angry fans starting a riot.
  • Ox Baker had in fact already killed one man, but what really cemented him as one was the defeat he suffered to Ray Gunkel in August of 1971, as Gunkel succumbed to the injuries he had received at Baker's hands after being declared the victor, proving that even winning a match against Baker didn't mean it wouldn't be your last.
  • The Iron Sheik: Easily defeated then-WWF hero Bob Backlund to win the WWF World Championship. Backlund, who had held the title for nearly six years, had been injured by the nefarious Sheik a few weeks earlier during a Persian club-lifting challenge, and when it came time for the title match, Backlund – who already had at least one nationally televised pinfall victory over the evil Iranian – was no match for the Sheik. Not to worry: a new hero was waiting in the wings … .
  • Hulk Hogan: Of course, the Hulkster had several wrestlers attempt to break him as well, most notably King Kong Bundy, André the Giant and Earthquake. Even though both Bundy and Earthquake injured Hogan, and André scored a controversial, Hogan always averted the trope … until one June day in 1993, when the Japanese sumo wrestler Yokozuna flattened Hogan, in dominating style, in his final match during his most famous WWF run; Hogan sold being burned in the face as he was led from the ring following his loss … and for nine years, that was the last image WWF viewers had of him – a broken, defeated hero with the villain and his stooge, Mr. Fuji, gloating in the ring over their victory.
  • Vader's run in WCW in the early 1990s began with him effectively squashing Sting in a decisive fashion, winning the WCW World Heavyweight Championship. He also sent Nikita Koloff into retirement, legitimately broke Joe Thurman's back and beat Cactus Jack to a bloody pulp. He's widely considered the best monster heel in all of professional wrestling.
  • In the dying days of WCW, Scott Steiner was this, credited with putting Sting, Diamond Dallas Page, Kevin Nash, Booker T and Sid Vicious out of action by "injuring" them.note 
  • This was essentially the point of Randy Orton's "Legend Killer" gimmick; he severely injured several of WWE's most famous and legendary personalities, in some cases even forcing their retirement. He's been doing something similar with his head punt of DOOM, which has put several people on the injured/reserve list for months with concussions. It's wrestling, so you can't quite stretch Kayfabe to cover killing the faces, but Orton comes about as close as you can.
  • Madison Rayne was infamously given a "career killer" gimmick, where TNA would credit the knockouts it released (Roxxi Laveaux and Tara) to her. Although she was eventually defeated by a released knockout TNA decided to bring back (Angelina Love).
  • Mark Henry in his heel turn. He took out The Big Show and Kane by breaking their legs with a steel chair and a squash, leaving them out of action for weeks and a few months respectively. He even went to the point of even giving Randy Orton who was World Heavyweight Champion a hard time. The result at Night Of Champions? He becomes World Heavyweight Champion!
  • Brock Lesnar: 2014 is shaping up to be the former NCAA champion's greatest year in wrestling, and it's easy to see why. The Beast ended the Undertaker's WrestleMania winning streak at 21, in arguably a hard-fought victory. But the greatest moment was yet to come, as he completely dismantled and dominated John Cena to win the WWE World Championship at SummerSlam 2014; Lesnar rarely, if ever sold any of Cena's offensive moves while crushing the now former champion with 16 consecutive suplexes. After both matches, Lesnar's manager, Paul Heyman, used Moment of Awesome promos to put over Lesnar as a conquerer who cannot be beaten and that the fans' heroes are not only ineffective but inept in taking down the Conquerer.
  • Zack Sabre Jr. used the 2018 New Japan Cup to establish himself as this, reaching the finals by defeating crowd favorites Tetsuya Naito, Kota Ibushi and SANADA and winning the whole thing by making Hiroshi Tanahashi submit.

  • Shadowhunter Peril:
    • Lilith. Her wrath is inescapable, and every single character knows that when she appears, it is time to run. Even Valentine knows that he shouldn't mess with her. She is one of the few characters in the entire story that can fight on equal terms with an angel (and possibly win). She is completely ruthless and has absolutely no qualms about killing any of her own family: she shoved her hand through her son Umbra's chest, and squeezed his heart till it exploded, then dropped him unceremoniously onto the ground and laughed, all just so she could psychologically disturb the watching Resistance.
    • Oblivion eventually surpassed Lilith as the Hero Killer. While Lilith is powerful in her own right, it's revealed that she CAN be defeated by Umbra and Nicholas if they work as a team (Umbra distracting her while Nicholas powers her up and then hits her with a dragon made completely of fire and wind). Oblivion is no such thing. He beat Umbra within an inch of his life and tossed Nicholas aside. Even Puriel, who is the most powerful character on the Light side, is pushed to his limit whenever he meets Oblivion. It's really shown in the final battle, where Oblivion effortlessly kills Ra (a giant phoenix god-king who commands an impressive army of 9-foot-tall phoenixes) in the first few moments of the final battle. Then he finally kills Nuriel, an angel of God who is, for all things considered, Shadowhunter Peril's God of Blizzards. This manages to drive Puriel into a Heroic BSoD. When Puriel snaps out of it, his ensuing battle with Oblivion rips up half the city and it only ends when Puriel manages to rip out Oblivion's heart and then finally kill him. And even then, there's evidence that he might not be totally dead.

    Tabletop Games 
  • Jasper Stone in Deadlands (the dude on the cover of the main book). He ends up specifically assigned to this role by the Big Bads.
  • Dungeons & Dragons
    • It's only level 20, but the Heroslayer Hydra in 4e is meant to fill this role. It's designed to make "tank and spank" strategies useless or near-so by dishing out a lot of damage from multiple attacks, and getting a large damage bonus against anyone who "marks" it and tries to force it to attack them. The ability is appropriately enough called "heroslayer."
    • Mephistopheles from 4th and older editions of D&D. Other archdevils do as well, but Mephistopheles is the most visible.
    • If an entire dungeon can count, the classic Tomb of Horrors module and Forgotten Realms' Undermountain definitely belong on this page.
    • The Tarrasque was created as basically the single most powerful monster in the world that didn't live in another world. It was essentially Godzilla for D&D.
    • Orcus was supposed to be this in 4th Edition, but this mostly led to people custom-building parties to beat him and then bragging about it.
    • Dragons also tend to be more powerful than their Challenge Rating would suggest, partly so that encounters with them would be more memorable.
    • Elminster, the iconic wizard of the Forgotten Realms setting, manages to invert this; with many groups gathering their party for the not-terribly-difficult task of killing him despite his status as one of the strongest and most important people in the setting. The developer's official stance on this practice is "Nuh uh, he's too smart."
  • This is the point of the 'character-killer' build for heroes in Warhammer and Warhammer 40,000. The Eldar Farseer's Mind War psychic power is a particularly good example.
    • Skulltaker from the Daemon books is quite literally made for this. The fantasy version has Killing Blow on 5+ and the 40k version wounds anything and inflicts Instant Death on 4+. Of course, a significant amount of characters are immune to Killing Blow or Instant Death, which reduces his utility somewhat.
      • The fantasy version also had Karnak, an who had the ability to mark an enemy unit and re-roll and failed hits or wounds against it.
      • Fantasy also has Wulfric the Wanderer, a champion of Chaos with the unique ability to force anyone to duel him one-on-one, allowing him to take out heroes not suited for melee such as wizards, or even just weaker heroes who would normally want to avoid fighting him.
    • There's also a whole style of magic in Fantasy based on this. The Lore of Death is packed full of some of the most powerful damage spells in the game, but they focus primarily on targeting heroes in a crowd and sniping them for massive, if not instantly fatal, damage.
    • The Blood Angels's Sanguinor has the ability to choose one enemy Independent Character and re-roll To Hit and To Wound dice in close combat against said character for the game's duration.
      • Also from the Blood Angels is Mephiston, who has an ability that forces an enemy character in contact with him to take a leadership test with a minus 4 modifier, and he gets to re-roll any failed To Hot and To Wound rolls for the round of combat if they fail, which coupled with the fact that he has Force Sword, means whatever he's fighting is likely to die in that unless it's not immune to instant death. Of course, Mephiston is strong that enemy characters will generally die against him regardless.
    • The 5th Edition Tyranid codex brings us the Swarmlord, a unique Hive Tyrant that the Hive Mind reincarnates when a hive fleet can't beat its prey through normal means. Not only is the thing a cunning strategist, it wields four energy-charged swords, and was capable of beating Marneus Calgar, Chapter Master of the Ultramarines, in hand to hand combat (given, Hive Tyrants are large, so that may not be as hard as it seems).
      • In game, the Swarmlord follows this in that is swords force an enemy to re-roll successful invulnerable saves and inflict instant death, though the Swarmlord is so expansive it's probably only worth using in an Apocalypse game.
    • The 7th edition Warriors of Chaos rulebook tends to somewhat encourage keeping hero killing in mind when building an exalted hero or chaos lord since they can roll on the eye of the gods table and, likely, get stronger from it. Oddly a Chaos Lord getting rolls on this makes him stronger than a Daemon Prince.
    • 6th edition codex Chaos Space Marines brings us the Murder Sword, nominate a target, when the bearer is in base to base contact with the target, the sword becomes double strength, ignores armor, and gains instant death. Wait for enemy player to challenge, swap the challengee with a model in base to base with the challenger, laugh manically while your daemon prince has a fun time
    • In-universe, Fulgrim. So far, canonically, including the Horus Heresy novels, he's killed one Primarch, came within inches of killing a second (admittedly one on his side), and is ultimately going to mortally wound a third. Any Traitor Primarch could qualify if the loyalist heroes they've butchered get counted, but Fulgrim goes the extra mile by being the one with the most Primarch blood on his hands.
    • The Officio Assassinorum is the Imperium's answer to tough questions that need to answered a single, surgical attack against enemy leaders. The types of assassin include:
      • Callidus shapeshifting infiltrators that get close to targets to kill them with a special phase sword.
      • Culexus are humans with 'empty souls', psychic blanks that disorientate their targets.
      • Vindicare are extremely accurate sharpshooters.
      • Eversor assassins are drug crazed close combat monsters capable of ripping apart an entire enemy command structure, often finishing the job by literally exploding.
      • Venenum are infiltrating poisoners, often tasked with large scale secret massacres.
      • Vanus assassins are master intelligence gatherers, putting into Just as Planned actions that take out their targets without anyone even suspecting an assassin was involved.
    • Warhammer Fantasy now boasts three with Games Workshop finally changing the status quo, with Arkhan the Black, Otto Glott and Tyrion killing several major characters in the End Times books along with several named playable characters including Eltharion, Kurt Helborg and Orion.
  • Exalted features one of these in the corebook in the form of Octavian, a Second Circle Demon. For comparison, the Solar Exalted are designed to be bastions of good, the righteous god-kings of Creation, with all the corporeal and celestial power that comes with the office. Octavian carries three of their severed heads on his belt- and as a Second Circle, there's all the Third Circle Demons above Octavian even before you reach the Yozis...
    • Hilariously, due to the glitchy nature of early Second Edition, he's only a mild threat, and thanks to sorcery, it's quite possible he never actually gets as far as a fight-a comic has an impatient Arianna blast him with Adamant Circle Banishment, sending him screaming back to Malfeas. One assumes he doesn't consider being banished an actual loss, since his opponent cheated. A better example would be the Wyld Hunt, the organization of Dragon-Bloods devoted to, among other things, killing Celestial Exalts before they become a threat to the Realm.
    • This is also the primary role of Day Caste Abyssals and Scourge Caste Infernals. Unfortunately for their respective groups of Big Bads, the signature Day Caste has as his primary goal getting into Harmonious Jade's pants, and the signature Scourge is so arrogant he even annoys Adorjan.
  • The Necessary Evil RPG, in which the Super Villain PCs are La Résistance on Vichy Earth, has Hero Killer ammunition, known as HK rounds. Basically, bullets designed for killing people who are Immune to Bullets.
  • Mechanically speaking, Tsabo Tavoc of Magic: The Gathering. Her abilities stop other legendary creatures from damaging, blocking or even targeting her at all, and she can kill them easily with her activated ability. In the storyline, Gerrard beats her, despite this being all but impossible in-game for the aforementioned reasons.
    • For a storyline example, we have the vampire lord Crovax. He kills the cat-woman Mirri, his "guardian angel" Selenia, and repeatedly kills and tortures the immortal goblin Squee. He is the commander of the Phyrexian invasion of Dominaria, which winds up causing a lot of death and destruction. He even kills and eats the aforementioned Tsabo Tavoc when she fails to kill Gerrard Capashen.
  • OblivAeon in Sentinels of the Multiverse takes out Ra and the entire Ennead in an early appearance, causes the death of the Scholar (who gives his life to save Guise), and is such a massive threat that Nightmist has to sacrifice herself to buy a chance at beating him. He's even worse on the actual tabletop, where his game mode is best described as hurling hero cards into a meat grinder in order to buy a chance; it's extremely rare to defeat him without at least one incapacitation, and losing fourteen people in games the heroes win is not unheard of.

    Video Games 
  • Dark Samus of Metroid Prime 3: Corruption. The game introduces three other bounty hunters. By the end of the game, Dark Samus has killed and absorbed all three of them.
  • Barbatos Goetia from Tales of Destiny 2. The first and foremost thing he's known for is killing the prequel's hero Stahn and he's off to claim the heads of other heroes, namely Philia and Garr. His legend as a Hero Killer has even stretched to Tales of Vesperia, where he reappears as a bonus opponent in the battle arena and his name is Killer of Heroes. Indeed, it turns out that his entire purpose in life is to kill the heroes of the first game under the orders of the Big Bad to remake the timeline. Nothing less can be expected of one voiced by Norio Wakamoto.
  • Misery from Cave Story kills King and Balrog forces Toroko to eat the Red Flowers which makes her go rabid and die. However Misery and Balrog are being controlled by The Doctor who killed Arthur Toroko older brother so he’s technically more responsible.
  • Every time Vladimir Makarov from Modern Warfare appears in the flesh, without exception, a Player Character either dies or gets critically wounded, usually along with other important characters as well. He exceutes Allen at the end of "No Russian"; he guns down Harkov when hijacking the President's plane; he sets up the ambush that kills both Kamarov and Soap; he kills Yuri at the end of the third game. Basically, anytime Makarov appears, it is bad news. In addition, though he doesn't appear when he does it, he also detonates the nuke that kills Jackson and Vasquez in "Shock And Awe".
  • Nikita Dragovich in Call of Duty: Black Ops. One of his introduction in Reznov's flashback showing him killing Dimitri Petrenko, the Player Character of the previous game. Also his dragon, Kravchenko, tries to be one, but almost always foiled, even when he returned briefly in Black Ops 2, when he again, failed to kill Mason and Woods, even then he indirectly killed Bowman.
  • Raul Menendez in Call of Duty: Black Ops II is an even straighter example. Just count how many named characters he killed, more than half are playable.
  • Gabriel Rorke in Call of Duty: Ghosts. While the only ones he killed onscreen are Ajax and Elias, it is implied that he killed many other Ghosts as well. He also drowned in a burning train and shot in the chest and ultimately walked away just fine like nothing happened just minutes after that and kidnapped the player character about halfway after the credits roll.
  • Suikoden: Childrich of Suikoden V can serve as one, particularly during the Final Duel against him. The player can elect to take along several other heroes with personal grudges against him, who then all try to call Leave Him to Me at once; you can select which one fights him... and they can die if he beats them, forcing somebody else to step in and take up the fight.
  • Because you play as a Villain Protagonist in Evil Genius, this game inverts this trope: the five super agents are the only ones capable of permanently killing your henchmen. However, you can play this trope straight by doing special sidequests to permanently defeat each agent.
  • Nyx from Persona 3. Ryoji tells the heroes, at least half a dozen times, that "Nyx cannot be defeated." He's right. There is no way to defeat Nyx. The main character puts his entire being into an ultimate attack, effectively commiting suicide, just to make her leave.
    • That's because Nyx isn't so much an entity as the entire concept of death. As My Life Is A Goddamn Mess puts it "You can't defeat Nyx, much like you can't defeat the color blue."
  • Lavos from Chrono Trigger kills the main character, Crono. It's entirely possible to proceed to beat the game without him, unless you carry out a sidequest to bring him back using the titular Chrono Trigger.
  • Alma in F.E.A.R.. It kind of helps that bullets do jack against ghosts.
    • Alma is a special case in that she's an accidental Hero Killer. In F.E.A.R. she just wants to HUG Point Man because he's her son but her presence is so lethal that even such a harmless action can kill. It's kind of heartbreaking - all she wants is a hug, but letting her do that will kill you, so you have no choice but to shove her off. And in Project Origin she's got a gigantic crush on Beckett, and wants to mate with him. That, incidentally, is also why at several points in the game she actively lashes out against anyone who's even looking at you funny. She ends up getting what she wants and nailing Beckett in the ending. He somehow survives the intimate contact with his life and body intact, which probably means he's the most badass character in the series, but unfortunately, his mind is likely a different story.
  • Mass Effect:
    • The Collectors in Mass Effect 2 can be seen as this, though it depends a lot on player choice and skill. From the first scene, you know they're bad news when they kill your character from the first game. In later story encounters, they tend to be very difficult fights, and the team has to pull out a lot of stops just to survive; in the final mission against them, it's possible for everyone to die, and without excellent planning, at least one or two characters will die. In one case a Harbinger-controlled Collector deals the deathblow.
    • Mass Effect 3 gives us Kai Leng, who had previously established his credibility in the Mass Effect novels. Unfortunately his stealth-assassin skills don't translate well to direct confrontation, making him look less effective in the game proper and his competence is disproportionate to Shepard's, meaning that as long as the player keeps certain people alive and warns others of him they can make Leng look quite incompetent, with his only successful kill being Thane Krios, a terminally-ill Drell that he was largely fighting to a stalemate because Thane is a badass.
  • Implied in the novelization of Resident Evil 3: Nemesis: the book discusses the trope. Not knowing that Nemesis is the name of the monster, Jill refers to it as the "S.T.A.R.S. killer". Fittingly too, as his Establishing Character Moment involves killing Brad with his bare hands, turning to you, ominously growling "STARS...", and proceeds to stop at absolutely nothing to kill you too.
    • In the main series Wesker is responsible for deaths of all S.T.A.R.S members with the five exceptions of Chris, Jill, Barry, Rebecca and Brad... the last of whom is killed by aforementioned Nemesis. In Resident Evil 5 Wesker almost kills Chris in a Flash Back making Jill do Heroic Sacrifice to stop him and Sheva tries to do the same before Chris saves her.
    • Alexia in Resident Evil – Code: Veronica turns Steve into a massive monster and then kills him.
    • Saddler from Resident Evil 4 kills Leon’s best buddy Luis and would have effortlessly killed Leon too, had Ada not shown up to harmlessly pump dozens of bullets into him before blowing up Leon's escape route instead.
  • The Emperor in Final Fantasy II racks up no small total of heroes slain. Most notable are Cid, who is fatally wounded by the Emperor's Cyclone, and Ricard Highwind, whom the risen-from-Hell Emperor kills personally when Ricard pulls a You Shall Not Pass!.
    • The Not-So-Harmless Villain Count Borghen's actions lead to the fall of Fynn and the death of Prince Scott. He even has the distinct dishonour of being the first villain in the series to kill off a party member, Josef, who dies saving the others from Borghen's boulder trap.
  • Final Fantasy VII: Sephiroth. You spend most of the first disk following Sephiroth and observing dozens of bloody murders in his wake, including several key NPCs, two impaled party members, and the Midgar Zolom hanging from a tree.
    • While he gets his actual significant kill in the game, it's really in the movie Advent Children that he shows the power backing up his claim for the title. As soon as he appears, he forces Cloud to stretch himself to twice as superhuman feats as he has so far (and that's saying something), while he himself doesn't even get out of breath. Especially in the extended version, where he beats Cloud within an inch of his life before the inevitable Heroic Second Wind kicks in. Cloud has already defeated opponents like the ridiculously powerful Remnants of Sephiroth and a gigantic dragon god, but his reaction upon first seeing Sephiroth can be described as "Eep!".
    • The Shinra Electric Power Company who Sephiroth previously worked for are technically responsible for more deaths than him. In Disc one they butcher Wedge, Biggs and Jessie of AVALANCHE then kill everyone in Sector 7 families and children included. Not to mention gunning down dear Zack Fair in Flash Back.
  • Sin from Final Fantasy X. Cuts a swathe of destruction and leaves nothing but ruins in its wake wherever it treads. Still, that does not deter the many organizations that rise up to Spira's defense and try to defeat him. Just ask the Crusaders how well that went....
  • Witches in Left 4 Dead. Normal zombies, even in a horde, are fairly easy to survive; smokers and hunters are usually just an annoyance; tanks are deadly and very scary, but an effective team can take them down without getting hurt; but the only appropriate response to a witch is Don't Ask, Just Run.
    • As time goes by and people learned proper tactics for handling witches, serious Villain Decay set in. High level players outside of tournament matches have made a sport of killing witches in the most outrageous ways possible, such jumping over her, spinning around, and shooting her point blank with a shotgun for an instant kill. In competitive play, if something's going to kill an entire team of survivors, it will be a tank.
  • Doppelgangers in Dot Hack GU.
    • Tri-Edge/Azure Kite. The dude is just... plain... unstoppable. Pretty much every appearance he makes involves someone getting Data Drained and comatose. He's only defeated twice in the series, which barely slows him down at all.
  • Starcraft: Sarah Kerrigan as Queen of Blades. She has used her Swarm to kill six people with major roles, all of whom were badasses of their own rights, was the mastermind behind the deaths of two more and drove a last one into suicide after defeating him in despite being seriously outnumbered. The sequel also sets up the Hybrid to be this, although they hadn't yet has the chance to present this, but whenever the protagonists encounter them, they are a source of fear and can cause Non-Standard Game Over by killing your hero.
  • Arthas Menethil, The Lich King, from Warcraft and World of Warcraft. He killed many named characters and many of them are badass in their own right.
    • Although it comes back to haunt him in a big (not to mention literal) way. His runeblade Frostmourne steals and entraps the souls of everyone it kills (oh, and his, too). At the climax of his encounter in Wrath of the Lich King Frostmourne is shattered by an attack and all the souls in question are freed — including his own.
  • Mephiles the Dark from the infamous Sonic the Hedgehog (2006). In the Last Story, he actually kills Sonic to get Princess Elise to cry, setting the chain of events that nearly destroyed time itself.
    • About 12 years later, there is Infinite from Sonic Forces. Powered by the reality-warping Phantom Ruby, Infinite is Dr. Eggman's ultimate weapon and probably one of the most violent and sadistic characters ever in a Sonic game; he defeats and seemingly kills Sonic in their first battle, kills several Resistance fighters on-screen and enjoys graphically taunting characters about how painfully he's going to kill them.
  • LeChuck from the Monkey Island series. Though he plunders, tortures and even kills hundreds upon hundreds of people (and even forms his own skeletal army from these corpses), his plans to rule the entire Caribbean keep getting thwarted upon many defeats (and deaths) at the hands of the main protagonist Guybrush Threepwood. It is not until Tales of Monkey Island that, after spreading his own Pox on the entire Gulf of Melange (while becoming human himself), LeChuck proceeds to kill bounty huntress Morgan LeFlay by stabbing her with her own blade in Chapter 4, and then saves Guybrush's life from the gallows... only to kill him with the Cutlass of Kaflu later on in the chapter when all the Pox is absorbed from the entire Gulf of Melange into the legendary Esponja Grande, which LeChuck then uses to reabsorb the Voodoo powers back into himself and then, while using the power of his hypnotized monkeys, to gain his powers from the Crossroads and become the Pirate God capable of unleashing destruction upon the entire Carribean.
    • Its even more apparent if you check the gravestones at the start of Chapter 5. As well as some Grave Humour, you'll find the names of several characters from previous chapters. It's heavily implied he killed them all after getting his powers back.
  • Subverted with Akuma The Raging Demon from Street Fighter as despite his reputation for murder canonically he’s only killed about two dudes. For a while it was a big deal that Akuma killed his brother Gouken Ryu and Ken’s sensei but in SFIV to reveal Gouken put himself in a coma and woke up healthy.
    • Played straight with M Bison whom counting the Alpha series, the Udon comics and SFV has killed Charlie Nash five times. Bison also killed Chun-Li’s dad, Juri’s parents and T.Hawk’s dad though for him it was all Tuesday.
      • Bison’s proud Number Two F.A.N.G killed Rashid’s female scientist friend, killed März one of the Dolla and poisoned Rashid himself.
  • In Mortal Kombat 9, a Brainwashed and Crazy Sindel becomes one for all of thirty seconds.
  • ZODIAC Virgo from RefleX establishes its danger credentials early on by one-shotting the most powerful boss the game had thrown at you thus far from offscreen. In subsequent stages it can be seen flying around in the background, getting chased and yet not destroyed by friendly forces, and finally effortlessly kills another boss that had been specifically built in order to counter it and destroy it. At this point, you take it on, but after a bit it gets serious and kills you with an overwhelming barrage you have no hope of surviving. It's only by virtue of 11th-Hour Superpower activated upon your death that you (or, more accurately, your machine) gains the means to stop Virgo's rampage.
  • Amante Furlair in ZoE: Fist of Mars who is either directly or indirectly responsible for every single notable character death aside from Ares and Ned and she's only 15. Amante is essentially the Azula of mecha games. It's a real shame the cast has not appeared in SRW, as she'd likely have a reputation equivalent to that of Simo Hayha with a Colony Drop being the FIRST response to any sighting of her. She even mindrapes then kills Team Pet bishounen Philbright, turning him against you before discarding him as being useless as a pilot. And to top it all off she gets away with it all too because Kojima got too wrapped up doing endless spinoffs of Metal Gear Solid to have time to return to ZoE! In the end she is revealed to be a top-ranking soldier of BAHRAM, the terrorist organisation from the original ZoE, and inserted herself as the coquettish psycho clingy girlfiend to everyone merely to off BOTH sides of the civil war so BAHRAM could move in unopposed. While she isn't totally successful, considering the player's team is the only opposition remaining on Mars it's a good bet the BIS would have had an amazing uphill battle of Sisyphean proportions.
  • General RAAM from Gears of War. He kills Minh Young Kim in his very first cutscene, and then, in the RAAM's Shadow DLC, he offs Alicia Valera, and almost kills Jace Stratton, not to mention the countless Gears and Onyx Guards he murders.
  • The Dahaka in Prince of Persia: Warrior Within is a being whose only point in existence is to be this. When a being somehow avoids their own fate, in and of itself a rather admirable fate, a Dahaka is created to destroy them. The Prince can only defeat it with the Infinity +1 Sword; otherwise he cannot even harm the beast.
    • The Dahaka is so well known for this, a lesser-known band called Merkabah actually has a song about it, appropriately named: "Dahaka". A transcript of the Metal Growled opening (lyrics are difficult to retrieve on the internet, and no easier to understand): "Sometimes it was whispered; sometimes it was read: the secret incantation that filled with the enemy with dread. If you knew it, if you used it, you could reach back to [unsure]. But stop and [think?; if one can see it]: Sole Master Of Your Destiny You Would Be. Dahaka is released. Dahaka: the Guardian of the Timeline. [A sentence; possibly "Eternal pursuer for fiddling with time."] NO ONE ESCAPES THE DAHAKA."
  • Vordred fits this trope to a T in AdventureQuest Worlds, and he has quite a list ahead of him. First off, he turns paladins undead and adds them to his "trophy collection", plus his skull-covered armor is almost invincible to any attack, even light-based attacks. Also, there's an area named after him where you fight him and find that he takes NO DAMAGE whatsoever, resulting in a Hopeless Boss Fight (at least until the Doomwood Part 1 finale with the Multiple Endings and a challenge fight). And as if that's not enough, the experiment performed on him by ArcAttack, with (believe it or not) help from the hero, manages to make him EVEN MORE POWERFUL. Oh, snap.
  • Etrian Odyssey features an entire army of hero killers in the form of FOEs. Although they're not particularly important to the plot, they do get a textual introduction in each game warning the player not to foolishly try to fight them, which in this series is not an empty threat. Players that don't get the hint often mistake the first FOE they come across for a particularly nasty Early-Bird Boss. (a mistake made easier by EO's general Early Game Hell) Avoiding them requires three things: the realization that you are supposed to avoid them, knowledge of their movement pattern and prayer that regular enemies won't slow you down as you run the hell away.
  • Grand Theft Auto IV: The Lost and Damned has an unusual example with Niko Bellic, who kills Johnny's friends Jason Michaels and Jim Fitzgerald, whose assassinations are missions in the original game! What makes this example strange, the first spoiler aside, is how Niko never antagonizes Johnny and acts as an ally in two missions (where, in their final mission together, Johnny remarks that he wouldn't want to piss off Niko, after witnessing him slaughter dozens of mobsters on his own) and Johnny and the Lost never find out what he did.
    • And then in Grand Theft Auto V, Johnny himself shows up when the game introduces Trevor. He lasts about a minute before Trevor hits him in the face with a bottle and, while he's on the ground, stomps his face in.
  • Nippon Ichi's games (including the Disgaea series and Makai Kingdom) has Overlord Baal, an evil conglomerate of souls who possess others' bodies to spread terror throughout the Netherworlds. He is almost always the most powerful enemy in each game, only reachable through a lot of leveling and workoing your way through secret options, and is not only very high level, but has stats that are jacked up far above what a normal character would have at that level, plus awesome equipment. In Makai Kingdom, he's even safely tucked into the absurdly overpowered Battleship Yoshitsuna, meaning you'll have to take that out before you can get a shot at Baal himself.
  • Borderlands 2 has Handsome Jack. One of the sidequests you get in the beginning of the game reveals that in-between games Jack killed Helena Pierce, a major NPC in the first game. Later on, he ends up killing Bloodwing and more importantly, Roland. There's also Wilhelm, who is stated to have been capable of defeating the Vault Hunters of the first game.
  • In [PROTOTYPE], interestingly enough, the player character is the hero killer, for a given value of 'hero', that is. The game compensates through timed missions and zerg rushes.
  • Vile in his first appearance in Mega Man X (though he suffers from Villain Decay in his subsequent appearances.) He starts out the game utterly trashing X in a Hopeless Boss Fight, requiring a Big Damn Heroes moment from Zero to drive him away. Near the end of the game, X has likely picked up tons of upgrades and gotten the weapons of all the other Mavericks...and he still can't beat Vile. In fact, this time Vile beats Zero beforehand, requiring Zero to pull a Heroic Sacrifice after X's second beating just to destroy his Ride Armor and give X a fighting chance.
  • In Warframe the Grustrag Three are meant to be this, given that they inspire such fear that the normally calm and collected Lotus pleads for you to forget the mission and run when they're about to drop in. If you didn't bring your best gear they will uphold that reputation.
    • The Stalker also qualifies, at least in the early game, as an extremely rare inversion of the trope. He is an Ambiguously Human hunter who may or may not be undead, wearing a modified suit of Excalibur armor with unique weapons, immunity to the player's magic void powers, and above all else a determined hatred for his target. Rather than being a specific boss fight, The Stalker has a 1.5% chance of interrupting any regular mission, so long as the player has a 'death mark' from killing a boss. It is no exaggeration to say a new player who's still stuck wearing their own Excalibur suit will die inside of four seconds, usually as little as two.
  • Fallout 2 has Frank Horrigan, a titanic Power Armored super mutant, who's the Enclave's best soldier and the Final Boss of the game. The first time he's seen is when he slaughters a random townsperson and his family. Whenever he shows up, somebody's going to die, including the talking Deathclaws in Vault 13 (who he punches in half with his bare hands) and Matt, the Brotherhood of Steel member manning the San Francisco outpost. When you finally go toe-to-toe with him at the end of the game (and you have to, because unlike the previous Final Boss there is no talking your way out of it,) you find he has 999 HP (for comparison, the Final Boss of the previous game had half that,) 10 of every stat (even though in-universe he's not particularly smart,) and a plasma gun and melee weapon that are the most powerful energy and melee weapons in the game, respectively. Thankfully, the player can turn the Enclave base's turrets on him and gain the help of a nearby Enclave squad to help them out.
  • Shay Cormac, the protagonist of Assassin's Creed: Rogue is a former member of the mostly heroic Assassin's Order, who defects to their archenemy, the Templars, making him a rare protagonist version of this trope. In the game, he ends up killing Adéwale, who was the protagonist of Freedom Cry and is responsible for reducing the Colonial Assassins down to simply Achilles, the mentor of Assassin's Creed III. As the epilogue reveals, he was the man responsible for killing Arno Dorian's father in Assassin's Creed: Unity.
    • In the modern day, Otso Berg is the leader of Sigma Team, an elite squad dedicated to hunting down and eliminating Assassins. While he's been very capable in the past, a recent rash of failures have led some of his higher-ups to question his Hero Killer status.
  • The Pursuer from Dark Souls II is known to roam the land of Drangleic in order to track down and kill the Bearer of the Curse, and, considering his quiver of weaponry, is implied to have been successful up until your arrival. Not only does he show up in various early-game locations to kill you at the most inopportune moment, but there's more than one Pursuer if Castle Drangleic is anything to go by.
  • Infinity Blade has the God King. The initial mandatory tutorial places you as a nameless swordsman, bent on facing him. The prospect of your insisting to fight excites him, but he has his guard "Dark Knight" fathom your potency instead. Once you strike him a few times (having learned some basic controls) he immediately disarms you, and an impressed God King then slays you. Cut to actual gameplay: twenty years later, you are the son of the tutorial protagonist and you have arrived at the castle of the God King (who anticipates and desires your arrival, hoping to kill someone stronger than your father) - avenge your father. That is the entire game.
  • Super Paper Mario has Dimentio, a Monster Clown with the ability to manipulate dimensions at his will. At the end of Chapter 6, he kills a hypnotized Luigi after deciding that two failures is far enough, then kills the rest of the playable cast utterly out of the blue. Luckily, the heroes manage to get better, less luckily, he counted on it.
  • The chief antagonist in Pokémon Super Mystery Dungeon can turn Pokemon into stone, and has their eyes set on Legendary and Mythic Pokemon, who are some of the most powerful and respected/feared beings in their world. Rayquaza, the mediator between behemoths of land and the sea who also saves the world from the occasional meteor? Flees the planet while saying that it's the first time he ever felt fear after seeing it. Latios and Latias, twin dragons that can out speed jet planes and have enough psionic firepower to destroy a tsunami? Literally dropping like rocks after they failed to escape. The Legendary Beasts, who over power and are feared by the protagonists? Petrified with zero fanfare. Arceus, the very creator of the world? Well, what do you expect what happens to him at this point?
  • Xenoblade has the Face Mechon. Metal Face Kills Fiora, Zanza and the High-Entia Emperor. Bronze Face devours the entirety of Colony 6 sans Sharla, Juju, and Otharon.
  • The Legend of Zelda:
    • The Legend of Zelda: A Link to the Past takes place in the timeline where Ganondorf managed to kill the Hero of Time, resulting in him and the Sacred Realm being transformed to reflect his dark desires.
    • In the backstory to The Legend of Zelda: Breath of the Wild, Calamity Ganon easily defeats all five of Hyrule's champions upon his return — Daruk, Revali, Mipha, Urbosa, and even Link himself — despite them being the strongest warriors in the land who had been deliberately preparing to defeat him. Four of the champions were imprisoned in the Divine Beasts and presumed dead, (they are), while Link was only kept alive by the swift actions of his allies and was forced to slumber for a full century in order to recover. Because Link failed in his duty to stop Calamity Ganon, many of the people he encounters blame him for the deaths of the others and the subsequent ravaging of the kingdom.
  • In The Elder Scrolls series' backstory, the ancient Atmorans (Precursors of the modern Nords) went to war with Skyrim's native Falmer (Snow Elves) after the Falmer sacked and slaughtered the Atmoran colony of Saarthal in Skyrim, with the Atmorans going so far as to attempt to drive the Falmer to extinction. After nearly wiping them out on the mainland, the Atmorans pursued the remaining Falmer to the barren, frozen island of Solstheim. During the Falmer's Last Stand at the Battle of the Moesring, an individual known only as the Snow Prince single-handedly turned the tide of the battle, killing many prominent Atmoran heroes in the process including Ulfgi Anvil-Hand, Strom the White, Freida Oaken-Wand, and Heimdall the Frenzied. The Atmorans, despite their hatred of the Falmer, considered the Snow Prince such a Worthy Opponent for his deeds that, after his death, he was buried with full honors befitting any great warrior, with guards even stationed at his tomb, which would one day become Jolgeirr Barrow.
  • Fire Emblem: The Blazing Blade: Jaffar acts as The Brute to Nergal. It stands to reason that he's dubbed The Angel of Death, and is the first Assassin class character in the series.
  • In Red Dead Redemption II we have Micah Bell, a career criminal and hitman, who is responsible for the downfall of the gang thanks to working with the Pinkertons as well partially responsible for Dutch's downward spiral and murdering Miss Grimshaw. He's also an absolute beast of a gunslinger. The final fight against him as John Marston is almost impossible because Micah is not only incredibly deadly, but he can No-Sell Dead-Eye and dynamite. Oh, and Micah will not hesitate to kill Arthur Morgan if the latter is low on honor as well.
  • In Sakura Wars (2019), there is Yaksha, an Evil Doppelgänger of Sakura Shinguji who ends up, near the end of the game, killing up Anastasia, Claris, Azami and Hatsuho in rapid succession.

    Web Animation 
  • Blood Falcon of CPU Championship Series who is the ONLY killer in the series, killing Parsec Captain Falcon, King Dedede and VINCENT, before he is defeated by Skillshare Kirby.
  • Mecha Sonic of Super Mario Bros. Z. Every single fight he's picked with the heroes has been a No-Holds-Barred Beatdown, starting from his first appearance where he very nearly killed Yoshi. Then later on with two chaos emeralds, he utterly annihilated the Koopa Bros. and the Axem Rangers within about two minutes of each other before completely wiping Yoshi's Island off the face of the Mushroom Kingdom. The heroes only narrowly managed to escape the same fate through a conveniently-placed Super Star, because not even Shadow could scratch him in a straight-up fight. And that's not even including what Mecha Sonic did to everyone on Mobius in the backstory...
  • Any Death Battle winner who either is a villain or anti-hero, or has beaten a hero or anti-hero.
  • The Meta from the Red vs. Blue Recollection trilogy, especially in the first part of the trilogy (Reconstruction) and the final episodes. He hunts down the Freelancers, an elite group of soldiers each a One-Man Army, and kills them himself, stealing their AI enhancements. It takes the combined efforts of the Red and Blue teams and a few surviving Freelancers to bring him down.
  • In the third Season Finale of RWBY, Cinder orchestrates Penny's destruction through Emerald and Pyrrha, and personally kills Amber, Ozpin and Pyrrha within minutes of one another.

    Web Comics 
  • Jack Noir, the Disc-One Final Boss of Homestuck, fulfills this role, along with being the Knight of Cerebus. His tally of protagonists killed includes Bro, John (twice), a second alternate universe Dave, the Dreamselves of most of the Trolls, a thousand Aradia clones, Mom and Dad, Rose, and Alpha universe Dave in "Game Over". He also killed his own king and queen, slaughtered two entire armies, destroyed three inhabited moons and twelve planets as well as all of the Exiles save PM and WV (the latter of whom only survives thanks to being healed by a dead alternate timeline Feferi), along with that entire universe.
    • Gamzee, after sobering up, is a downplayed version of this trope. His killing spree sees two victims—Equius and Nepeta—before he is calmed down, but he is still certifiably insane and his friends are constantly on edge since they never know when he'll snap again. Later, in "Game Over", he also kills Karkat and at least plays a significant role in Terezi's death, considering she dies from receiving numerous injuries, most of which were inflicted by him. Thankfully, John's retcon powers are able to fix this so it doesn't happen in the new alpha timeline. In an alternate timeline he went crazy much earlier and was able to kill all of the other trolls without much trouble.
    • Once Aranea comes back to life and is revealed to be a Well-Intentioned Extremist, she becomes this in her extreme measures to defeat Lord English, since she fully believes her way is the only right way and is willing to kill anyone who opposes her in the name of the greater good. Her victims include Jade, Jake, and Jane, and she, like Gamzee, is significantly responsible for Terezi, due to causing the latter to stab herself with her own sword; Terezi bleeds out later. Luckily, these deaths are also part of the "Game Over" timeline that John erases, meaning Aranea never gets the chance to be relevant at all to the new alpha timeline.
    • The Condesce, a.k.a. Betty Crocker, is certainly this as well. In the backstory of the post-Scratch (B2) version of Earth, she directly killed the B2 iterations of Rose, Dave, and Jade, and eventually caused almost all of humanity (save for Dirk and Roxy) to die out. She later kills Kanaya and B1 Rose (and also Aranea, but she's a villain rather than a hero), though the former two deaths get retconned like the rest of "Game Over", and in the final battle, apparently kills at least Kanaya and Rose again (though they are revived by Jane), and possibly Jane as well (who is also healed).
    • Lord English tops them all. Technically, most of the people he's "killing" are already dead, but exist as sentient ghosts in dream bubbles; he is able to completely destroy these dream bubbles and erase all ghosts within them from existence. This includes the alternate universe Dave that Jack killed, the John from Davesprite's timeline, and countless versions of the trolls.
  • Psi-Void became this in Deviant Universe by killing Great Man with ease.
  • Kore from Goblins was feared by the main cast of goblin adventurers even before they had met him. In their first encounter with the dwarven paladin, they were barely able to wound him. Notably, that fight ended with the death of Chief.
  • Xykon from The Order of the Stick has killed many heroes before the start of the series, including Lirian, Dorukan, and Fyron, that last one prompting Roy's father to pursue a quest of vengeance that Roy takes up upon his death. In the series itself, Xykon kills Roy too, and then the entire Sapphire Guard. Later, he curb-stomps soul-spliced Vaarsuvius in spite of their insane power.
    • After the Order are seemingly killed, Hobgoblins hand out T-shirts saying, "I killed a PC and all I got was this lousy T-shirt."
  • Lord Dragos from The Beast Legion falls invokes fear in everyone he comes across.
  • Pluton from Sidekicks was introduced as a villain who had killed 4 superheroes and 5 sidekicks before finally being subdued and taken to villain prison.
    • Metheos' group of villains turn into hero killers whilst collecting superpowers.
  • 564 from Chiasmataand the Chiasm ARG counts. While mostly offing civilians, 564 has exactly one survivor from one of his attacks. He has a bodycount in the thousands, and is bar none the most powerful superhuman in the setting. He's more dangerous than a man who has turned the southwestern United States into a glass bowl.
    • Nilhil sat in the same place and still managed to kill waves and waves of would-be attackers.
  • Levi Cole in The List is a professional superhero assassin. Though many heroes underestimate him, his reputation seems to have grown since the beginning of Season 2, when he killed the second in command of the Superior Six
  • Played for Laughs In Ensign Sue Must Die, the titular ensign is nigh-perfect, unstoppable, and armored with the heaviest Plot Armor available. But there's one thing that can fell even such a nigh-omnipotent entity. Give her a Red Shirt and let nature take its course.

  • Deathlist of the Whateley Universe. He's got the name because of the huge list of superheroes he has already killed, including Champion. The only person we know of who has survived this killer cyborg is Lady Astarte in the Halloween story, and she had help from a Reality Warper, a precognitive, and a really huge blaster. She still couldn't polish him off.
  • Worm:
    • The Eldritch Abomination Endbringers — Behemoth, Leviathan, and the Simurgh. Before a fight against Leviathan a veteran hero notes that one out of every four parahumans dying during the fight is considered a good day. Leviathan does the most geographic damage and the Simurgh is arguably the Big Bad of the Endbringers, but Behemoth is specifically referred to in-setting as the "Hero killer" due in large part to it's "Instant Death" Radius. For meta points, Wildbow has revealed that for the first Endbringer appearance he rolled dice for every single character involved in the battle to see whether they'd live or die (yes, including the protagonist; he had a backup protagonist in mind in case she died).
    • The Slaughterhouse Nine collectively also qualify, as they are basically parahuman serial killers, although they kill their share of unpowered individuals as well, and they kill or inflict a Fate Worse than Death on several main characters. In particular, Bonesaw tortures and nearly kills Grue soon after the Nine arrive in town.
    • Contessa is a parahuman who is informally known as "the boogeyman" among the cape community, in that pretty much every cape (hero or villain) that has ever tried to fight her has died or otherwise been defeated. It says something about her reputation when people with actual superpowers consider her an unstoppable monster, and one character's advice to the protagonist is Don't Ask, Just Run when they know Contessa is in the area. Of course her power is knowing exactly how to accomplish any goal she sets her mind to, so trying to fight back is a pretty meaningless exercise.

  • Monitors in Tales from My D&D Campaign are uber-powerful Kua-Toa Bare Fisted Monks, legendary for their sheer ridiculous power. The one time a Monitor is seen in the videos, it One Hit Kills a troll just because the troll happened to be in its way.
  • Malachite from Suburban Knights. Within his first scene he violently kills a man who annoys him, and his plot to destroy all technology in world is played much more seriously than Critic's feud with the Nerd or the reviewers' attempt to invaded Molassia. Orlando Belisle's subtle acting marks a sharp contrast to TGWTG's usual World of Ham. Also, he actually does kill Ma-Ti.
  • Similarly, Lord Vyce from Atop the Fourth Wall is a villain who is said to have killed the Champions of numerous universes before entering the Awesomeverse, and beats Linkara within an inch of his life in their first encounter. Not only that, but he remains a dangerous opponent through the entire Vyce Arc. Oh, and he comes back, too.
  • Critical Role:
    • Raishan is both an Ancient Dragon and one of Exandria's most powerful wizards. Despite being the Chroma Conclave's Squishy Wizard, she's tough enough to shrug off Grog's attacks and take off half of Vox Machina's health with a single Breath Weapon attack in her initial appearance. Even the DM believed confronting her before a certain point would have only resulted in a Total Party Kill, and she makes good on that presumption, causing a total of four Player Character deaths — Vex, Percy, and Scanlan twice — the most out of any foe the party has ever fought.
    • While he doesn't kill as many Player Characters as Raishan, Vecna deserves extra credit for how quickly he manages to do so. Within seconds of Vox Machina engaging him, they realize they don't stand a chance when he kills Vax and Vex almost effortlessly- and killing the former in a way that makes resurrecting him impossible (for anyone short of "basically Gods").

    Western Animation 
  • The Lich from Adventure Time. In the fourth season finale, he kills Billy and takes his skin, then uses it to trick Finn into helping him.
  • Batman: The Animated Series has the episode "The Man Who Killed Batman", in which a random lowly goon of Rupert Thorne's mafia named Sid "The Squid" Debris apparently managed to kill the Dark Knight himself. This trope then gets deconstructed because Sid killed Batman by accident and he's too much of a weakling to deal with the horrors that his new rep tosses at him.
  • Vilgax from Ben 10. Word of God is that his atrocities include destroying 4 planets and creating a black hole, and the dialogue in the series indicates that everyone is scared to death of him. When he first starts to act at the end of the 1st season, Ben's Old Soldier grandpa tells him to run when he sees him, some advice he should have taken as Vilgax promptly stomps him. When he makes a return in Ben 10: Alien Force, though for reason acting under rules of Galactic Conduct, these rules mean he gets to fight some champions from a planet and if he wins, the planet is his. Till returning to Earth, he never lost.
  • Kilobot from Cubix: Robots for Everyone spends his time feeding on the energy of other robots and copying their EPUs as ordered by Dr. K, growing stronger with each energy he feeds on and each EPU he copies. He eventually grows so powerful that Robixcorb decides that a stronger Cubix is the only hope to save Bubbletown from such a dangerous threat. Even so, in the second-to-last episode, Kilobot ACTUALLY manages to destroy Cubix at the end. Of course, it was just a temporary destruction, and Cubix pulled himself back together afterwards, and even then he needs to recruit help from Dr. K. and Kolossal to defeat this creep for good.
  • Dungeons & Dragons had a one-shot villain, the Evil-With-No-Name, in the episode "The Dungeon At The Heart Of Dawn." A being so powerful even The Dungeon Master and resident Big Bad Venger couldn't handle him, who could soar the cosmos and return to plague the realm at any time he chose, who could only be fought...maybe...with All Your Powers Combined? The fact that he only appeared that one episode is a shame.
  • Final Space: The Lord Commander is one of the most powerful beings in existence,note  with most people standing no chance against him. Only Mooncake has been shown to have enough power to temporarily stop him so far. In episode 6 he uses his psychic powers to plant a bomb on Little Cato, forcing Avocato to sacrifice his life to save his son. According to Nightfall, in hundreds of past timelines, the Lord Commander has always succeeded in murdering Gary.
  • Toonami's first event, The Intruder sees the titular villain kill TOM's original body. Its sequel, The Intruder II sees the creature return and has the creature kill SARA, then gloat about killing TOM 4 offscreen. However, SARA - much like TOM 1-3.5/5 - doesn't stay dead.
  • The Legend of Korra:
    • Amon, though his most important quarry isn't always needed to be killed. Immediately, at least.
      "I told you I would destroy you."
    • The Red Lotus is Book 3. They can wipe the floor with the White Lotus, and any bender who stands against them is as good as dead or captured. And being Bomb-Throwing Anarchists, the world as a whole doesn't stand that much more of a chance against them. They also manage to basically kill the Avatar, but Suyin saves Korra at the last possible second from the metallic poison, much like Katara did Aang.
      "Do you have any idea the power that these criminals possess? Individually, they can take down any bender. Put them all together, they can take down the entire world."
  • The Skullmaster from Mighty Max. In the series backstory he successfully conquered the Earth, and Max's predecessor couldn't beat him and was only able to seal him in the center of the Earth. Most of the appearances he makes have the heroes doing some running from him. In the finale he kills both the supporting heroes, and the best Max could do in a direct confrontation was cause a Gainax Ending.
  • Grogar from My Little Pony 'n Friends gets as close as this show would allow to this trope, as he more or less spends the entire special walking through everything the heroes throw at him and manages to basically conquer Ponyland within minutes of showing up. While he doesn't actually kill anyone, he certainly comes very close to doing so, nearly banishing everyone to the Realm of Shadows and raining bolts of lightning with intent to kill down on the heroes during the climax. It takes exploiting his Kryptonite Factor to finally beat him, and he does not make it easy.
  • Strike from the Crisis Crossover episode of Ok KO Lets Be Heroes is a villain that has been summoning heroes from different Cartoon Network shows (And Black Hat for some reason) in order to turn them into stone. It's up to K.O., Garnet, Ben Tennyson and Raven to stop him.
  • Samurai Jack:
    • Aku has defeated all would-be heroes who would try to end his reign of terror. This is in part because Jack's sword is one of the only weapons that can actually hurt him, so only Jack has any chance of defeating him.
    • Demongo has killed hundreds of warriors who tried to oppose Aku and enslaved their souls as minions. Although the end of his episode reveals he has little fighting prowess of his own and was dependent on his enslaved minions, he had to have killed at least one of them on his own to start his collection of souls.
  • ManBearPig from South Park, proves to be one of the, if not the, most dangerous and unstoppable antagonist in the show. He has massacred numerous people and among his high body count he has killed Kyle Broflovski, one of the main characters (he gets better), nearly kills Ned, a war veteran, and actually kills Satan, described to be one of the most powerful deities in the universe.
  • General Grievous from various Star Wars works, mostly in Star Wars: Clone Wars. In his first appearance in the first season finale he takes on five Jedi at once and defeats them with ease and a deadly sense of flair, killing K'Khruk, Tarr Seirr, and Sha'a Gi in the bout. The interesting thing is that this portrayal was based on an early design for Revenge of the Sith, only for him to be reimagined in the actual film as more of a Smug Snake who defeats minor Jedi but is fully aware that the main characters stand a shot at beating him and resorts to avoiding a fight whenever possible. The second season of Clone Wars tries to bridge the gap by having him take significant injury from a brief confrontation with Mace Windu, virtually a Physical God even among Jedi, and justify his hesitation to fight. Star Wars: The Clone Wars reworks everything, in a Broad Strokes fashion, where he heavily relies on cheap tricks and sending in his bodyguards first to distract and wear them down first. Thus he has the reputation of killing many Jedi and is a high priority target in the war but doesn't quite achieve the position of The Dreaded.
  • Star Wars Rebels:
  • The energy monster in episode 18 of Sym-Bionic Titan qualifies as this. The heroes were completely powerless against it because it was completely impervious to their attacks and could drain the energy out of machines and permanently drain the life out of them so they couldn't be recharged (considering the heroes use robotic battle armor and one is a robot, you can see why this counts). Becomes literal at the end of the episode by killing Octus. It takes the full fire power of the G3's ship and the explosion of the space station it was in to finally destroy it.
  • In the 2k3 TMNT, the Shredder is the turtles most feared enemy: he is responsible for murdering Hamato Yoshi (the trainer of the trainer of the turtles), and has never been defeated one-on-one with them. Special mention to the fact that he's actually beaten them on two instances despite them having Splinter with them in the late case because in his new exo-suit he flat out curb stomped them. The demon Shredder that appeared in the lost season also fits, with the Turtles trying to avoid fighting him till they can get more allies to help, and even when they do, and they have Karai draining his strength, it takes Deus ex Machina appearance by Hamato Yoshi's ghost to save them.
  • Nox, the Big Bad of Wakfu. His strongest creation, the clockwork monster Razortime, manages to become this trope in one episode. The moment it appears, the heroes realize it's really bad news. All of their efforts are pretty much useless against it and even Rubilax!Grovy is no match for it. Raxortime literally becomes a Hero Killer near the end of the episode by killing Grovy.
