Villains who have died and have remained dead. This category should only include villains that are currently deceased rather than ones who have "died," but then later returned. This is also for robots or machines that were destroyed/deactivated permanently or ghosts/spirits that were banished to the spirit world as well. Undeads cannot count unless they are also killed for good. This also includes villains who were erased from existence.

Various means how a villain died/remained dead includes:

• Violent Death: A villain winds up killed in a violent or disturbing way, such as fatally incinerated by an explosion, mutilated alive, etc. (e.g. Dio Brando, Ken Wheatley, Commander Vic Hoskins, Syndrome, Thrax, King Ghidorah and Marko).
• Died in Honor: The villain has accepted the fact that their demise is inevitable and had enough dignity to face it. Many of the villains who died in this way are honorable ones. Thus, circumstances were includes:
  • Chooses to Die Rather Than to Be Saved: Honorable villains defeated by the heroes choose to take his/her own life, preferring to die with honor rather than to live in shame like cowards. When they killed themselves, they can either give the heroes sometime to escape from disaster that they already started but cannot undone it (an example being the battle between the hero and the villain took place in the damaged ship/building that about to explode as result of the villains' own mistake or heroes' effort to foil their evil plan) or have the hero whom defeated him/her gave him/her a mercy killing (e.g. Doctor Octopus).
  • Heroic Sacrifice: When a villain commits a heroic sacrifice before death, it is regarded as a way of redemption and dying with honor (e.g. Darth Vader is a very prime example, sacrificing himself by throwing Emperor Palpatine in the core of the Death Star, saving Luke from death by electrocution; Kylo Ren transferred his own life force to Rey, killing himself in the process, when she was dying after being fatally wounded by Palpatine; Ingrid sacrificed herself to erase the Spell of Shattered Sight, redeeming herself and saving Storybrooke; Nagato reviving the Konoha ninja he killed during his invasion and Viggo fought his own men to the death to allow Hiccup & Toothless to safely escape Johann's cave; Gellert Grindelwald refused to tell the location of the Elder Wand to Voldemort; Mitch Wilkinson held the door of Cibola open, allowing the rest of Gates' team to escape safely and drowning himself in the process; Yondu Udonta puts the only spacesuit Rocket has given to them on Peter to keep him alive and dies shortly after).
  • Accepted Their Death as Their Fate and Faced it with Dignity: In this case, it needn't be a redeemed villain to die with honor. For instance, when Lord Shen saw his cannon falling down on him, he shut his eyes and allowed his end to come. Erik Killmonger was fatally stabbed by Black Panther, but instead of being cured and imprisoned, he chose to die watching the sunset of Wakanda. Nero accepted his death and closed his eyes when his ship was sucked into a black hole. Vincent was fatally wounded by Max. When he realized that, he simply sits on a train's seat and decided to have a last talk with the hero. Ra's al Ghul closed his eyes when he saw that Gotham's train on which he was on board was about to derail and crash. Erwin König, having fallen into a trap set by Vasili, slowly turned to him who is waiting next to wagon and took his hat off, allowing the hero to shoot him. Even a villain that is Pure Evil can somehow die with honor if they accepted their death with no fear. Some of them also held no grudge when the hero killed them as they simply accepted their fate (e.g. John Doe, Yuuki Terumi, Lord Cutler Beckett, Alien Empera, Acnologia, Amon Goeth, Brixton Lore and Wilford).
  • Fought with Honor: Villains who fought with honor in order to avenge, protect or defend others with no fear can die with honor (e.g. Hephaestus died at the hands of Kratos after attempting to back-stab him, but it soon turned out that Hephaestus was trying to protect his daughter Pandora from a certain demise. Kratos was deeply moved by it and promised to a dying Hephaestus that he will protect Pandora. Boss Wolf stood up against Lord Shen when he ordered to fire into his own men and get killed for that).
  • Remorseful Suicide: The villain goes aware of his wrong actions and thus, they discover it's already too late to their redemption. Instead, they take their own life to fix their wrongdoings, it can overlap with Heroic Sacrifice, most probably if the villain was a Pawn or Brainwashed/Possessed.
    • A good example of both of this is Shade (Cyberbots). After Jin defeated G.O.D., Shade, a brainwashed soldier of G.O.D., attacks Jin, so he can't destroy the weapon, but after Jin defeated him, he gained consciousness. Shade felt bad about the assassination of Jin's father, Ken, who was also his best friend, the one responsible of this hideous action was G.O.D. Thus, he used himself to destroy Earth Force’s Super Weapon as a form of redemption towards both, Jin and Ken.
    • Lamar Burgess is another good example. Anderton poses a dilemma for him: if Burgess kills Anderton, he will be locked up for the rest of his life, but PreCrime will continue; if he does not kill the hero, PreCrime will be discredited and arrested. When Burgess struggles to make a decision, Anderton tells him that the PreCrime system is already broken because people can change their own future once they know it. Knowing that Anderton is right, Burgess raises his gun, but rather than shooting Anderton, he shoots himself in the chest, begging for forgiveness from Anderton while dying. 
• Died in Disgrace: In this case, the villain commits something dishonorable or had no dignity to face their downfall. Related circumstances include:
  • Villains who try to kill the heroes after being offered mercy or spared to live, only to end up dying in the process (Gaston, King Stefan, Clayton, Fouchet, Frieza, Lord Henry Blackwood, Ragear, General Bethlehem, Murad, Mumkhar and Wade are good examples).
  • Villains who are killed by their own allies who come to realize just how evil the villain really is.
    • Jenner is a prime example after being literally stabbed in the back by his own henchman, Sullivan.
    • Aerys II Targaryen was slain by Jaime Lannister after Aerys told Rossart to detonate the wildfire caches and ordered Jaime to kill his father and bring Aerys his head.
    • Dick Hardly when the clones killed him after realizing that he never loved them.
    • Mason Verger is left to die amongst the boars (whom devoured him alive) by his associate Cordell.
    • Scar when the hyenas Shenzi, Kamari and Azizi mauled him, having heard him double-crossing them.
    • Harry was pushed off a cliff by his clan's leader, Dark as revenge for Harry killing all, but one of his and Suki's cubs.
    • Commodus is a variation. After he lost his sword in the duel against Maximus, he asks for another one but the captain of his soldiers refuses and stops his men from doing so, resulting for the Emperor to desperately cheating and his subsequent death.
    • Springtrap is this. After his old friend, Henry Emily, realised what a monster he is, he made a whole new pizzeria only to burn it once Springtrap and the other animatronics arrived. A week later, every animatronic arrived, allowing Henry to burn down the location and kill Springtrap.
  • Villains who die in an ill-conceived, foolish, and/or desperate attempt on the heroes' life, such as an "I'm taking you with me" type attack that backfires.
    • Gleeman Vox's failed attempt to kill Ratchet.
    • The Great Intelligence's reversed attempt to destroy the Doctor.
    • Pete Anderson's failed attempt to kill Rick Grimes, even going as far as to blame him for everything that had happened to him.
    • Danzo Shimura's failed attempt to seal Sasuke Uchiha and Tobi with him when he was already dying.
    • Nick Kudrow's attempt to push off Simon Lynch of a building's roof while surrounded by a FBI's team, only to be shooted to death in the process.
    • The Cleric tried to detonate himself, hoping to take down American soldiers with him.
  • Villains who try to weasel their way out of their predicament by trying to talk the heroes into mercy, only for the hero to kill them anyway because they know that the villain is only trying to trick them (Maman, Minister Mason, Muriel, Patrice Saint-Clair, Sentinel Prime, Raynare, Dimitri Rascalov, Henry Evans, Esther Coleman, Frank-N-Furter, Arkham, Dandy Mott, Steven Jacobs, Koba, Jack Welker and Oushima Sanagi are prime examples of such).
  • Arrogants or Egotists who spend their last moments questioning on how they could possibly be beaten (Menomaru, Supreme Leader Snoke and Tai Lung are good examples of this).
  • Villains pleading/begging for their death when they are being suffered/tortured.
    • Cato pleads for help when he was attacked by the Mutt Mutants, so Katniss, who couldn't bear the agonizing moans, ends his suffering by shooting her last arrow at him.
    • Szayel Aporro Granz, trapped in the drug of Mayuri Kurotsuchi, begs for his death, the sword coming closer, slowly through his senses, pleading it to hurry up as it pierces his heart, killing him.
  • Cowards who try to run away from their problems and kill themselves to avoid punishment (e.g. Samuel Norton and Patrick McKenna).
  • Former immortals who lose their sources of immortality and face their downfall either immediately or later on in the story. 
    • A good example of this is Lord Voldemort. After his horcuxes have been destroyed as well as effortlessly "killing" Harry Potter with the Killing Curse in the Forbidden Forest and Neville Longbottom, slicing Nagini's head off with the Sword of Gryffindor, Voldemort tries to strike Harry with the Killing Curse one last time, only for the Elder Wand to turn on him and kill him instead.
    • Another example is Ego, who gets killed after the explosion of a bomb was placed on his brain.
    • Mother Gothel crumbled into dust when her age caught up to her after Flynn Rider cut Rapunzel's hair, removing her only source of immortality.
    • The Kurgan was decapitated by Connor. Decapitating is the only way to kill immortals.
• Died Offscreen: In many cases, certain villains have met their fate onscreen. But, in this case, the villain's death was not shown, but was mentioned by a character that he or she met their fate when no one else was there to see it. An example of this is Noah Cross. In the sequel of Chinatown and The Two Jakes, it is revealed he died between the events of the two movies. There is also Frank Underwood who was poisoned by Doug to prevent him from assassinating his wife Claire Underwood.
• A Fate Worse Than Death: While death itself is the worst realistic thing that could happen to anyone, there are sometimes a few things that are worse than that. This mostly includes villains who are damned for all eternity, Theodore Victor Allen slowly agonizing tied on his bed, drugged and tortured by John Doe during a year, Ernesto de la Cruz likely condemned to being imprisoned under the bell because nobody will rescue him and even if he is rescued, he will be condemned to wander alone in the Land of the Deads because nobody will forget him because of his crimes, Alejandro Gutierrez having been imprisoned in Parapata for one thousand years and being forced to eat insects or Barty Crouch Jr suffering the Dementor's kiss.
• Extinction: This is not just the death of the villain, but also their entire species. This mostly includes villainous species that were wiped out either during an extinction event, brought it upon themselves, or were hunted to their extinction by the heroes or from a much more malevolent threat. An example of an innately evil species going extinct is the Shroobs. After their princess and elder princess were slain by the Mario Bros., Professor E. Gadd had invented a machine that melted the Shroobs away when the brothers and Princess Peach discovered the Shroob's weakness (babies' tears). In Bowser's Inside Story, Mario fights three frozen Shroobs, slaying them and finishing off the Shroob race for good.

By extension, none of the deceased characters can be a Karma Houdini if they have not died of natural causes, no matter their influence on the plot.

Characters who are confirmed dead rather than simply being presumed as much are different; please keep those categories separated.
