Kill the God

Deicide, aka killing a god.

To kill the gods, or even God (or a Crystal Dragon Jesus Expy) Himself, is a daunting task. You're often dealing with an Immortal, Nigh Invulnerable, Physical God that can probably snuff the light out of you in an instant.

But that doesn't sit well with how deities are portrayed in stories, where they have a tendency to die, as mythology often shows. As a result, you may have a setting where you can Kill The Gods. This makes sense if the character who kills the god is its equal or greater in power, although it's not unheard of to see someone who's weaker than the god kill them anyway.

If the Gods Need Prayer Badly, this could be accomplished by everybody ceasing worship at once and letting the god just shrivel up.

Of course, once you do this, God Is Dead. See also Rage Against the Heavens. Compare Did You Just Punch Out Cthulhu?, which might be their cause of death.

Anime & Manga

 * Almost happens to at the climax of The Astonishment of Haruhi Suzumiya Vol. 2.
 * Bleach gets this pretty easily, considering the Soul Reapers are considered Death Gods by their own submission.
 * In Princess Mononoke, Lady Eboshi kills the forest spirit, which is a sort of Physical God. The results, however, aren't quite what she intended.
 * An extremely difficult proposition in Saint Seiya, as the gods (with the exception of Eris in the first OVA) are really powerful, but possible with the right means. The real problem is getting them to STAY dead: Poseidon apparently died millennia before the series, but still managed to operate as a spirit and by Grand Theft Me.
 * A variation occurs in Code Geass.  and , having lost their parents to the machinations of their Deadly Decadent Court, promised each other as children that if there was a god that made people fight and scheme against each other for power, they would kill him. By the time they are older and in a position to put their plan into action, their understanding of the situation has sufficiently evolved that they're no longer trying to kill the "god" they have discovered, but they are planning to use it to

 * In the 2010 remake of Clash of the Titans, various rulers are trying to do this to the Olympians by destroying their temples and denying them worship.

It also doesn't do anything to weaken Hades, since he draws power from their fear of death.
 * The climax of Dogma involves the protagonist finding and killing God, in order to allow Her to respawn at the place She needs to be to stop the villain from destroying the universe.

Live-Action TV

 * On the Hercules and Xena Wiki, there's a category on the trope "Power to kill Gods".
 * The entire fifth season of Buffy the Vampire Slayer revolves around killing Glory, a seemingly unstoppable hellgod trapped in a mortal body.

Tabletop Games

 * Exalted is full of exaggeration, and this trope is no exception. You can trivially kill the vast majority of gods right out of chargen. And not only you can kill typical day-to-day house-spirit gods, you can also kill the Incarnae, who are the big bosses of the gods. And ultimately you can kill the Primordials, who are the gods of the gods. In fact, that last one was the very reason why the Exalted were created.
 * For an RPG based on Gnosticism, this trope is Averted in Kult. But only because God Is Dead.
 * Dungeons and Dragons
 * 1st Edition
 * Under the rules (Deities and Demigods Cyclopedia) it was possible to kill deities, which led to bizarre results. One example was a letter to Dragon magazine in which a PC killed the Norse Mythology god Thor by pushing him off the top of a wall and getting Thor's magical hammer Mjolnir as booty.
 * Module Q1 Queen of the Demonweb Pits. A high level PC group could could kill Lolth, the Demon Queen of Spiders, who was a lesser deity under the rules. If they did so her spider ship would cease to exist, but they would be saved and returned to the Prime Material Plane by their deities.
 * 2nd Edition
 * Legends and Lore supplement. Deities could only be killed by a more powerful deity or any deity using an artifact. Mortals could never kill a deity. Deities sometimes created avatars (lesser versions of themselves) to act on the Prime Material Plane. Avatars could be destroyed by mortals.
 * Killing gods were a fairly trivial task (although it's rarely easy) in 3.5e. 4E has a few deities statted up (Bahamut, Tiamat, Torog, Lolth at least), and usually require you meet some special condition to permanently beat them down (either affecting them in some way that violates their portfolio, using something against their iconic material, or getting a bunch of Primordials/Demon Lords and having them gang up on them).

Video Games

 * In The Elder Scrolls III: Morrowind, you can kill up to three Gods, with two being required to finish the story. They are Vivec, Almalexia in Tribunal (necessary to finish Tribunal's story), and Dagoth Ur (necessary to finish the main game's story).
 * Killing Mehrunes Dagon in Oblivion is supposed to be impossible (he's got something like 10,000 HP and can stomp you to death without half-trying), but can be done if you A) abuse the Alchemy and Enchant skills to make a Game Breaking enchanted weapon, or B) get lucky with Wabbajack.
 * The endgame of Skyrim subverts this.
 * God of War, of course. Kratos goes on a killing spree in Olympus as well as many other legends from Greek Mythology. Of course, killing the gods that govern the elements or the guy that guards the souls of the dead may have small inconveniences, but hey, no plan is perfect!
 * The ending of the first and third Silent Hill games.
 * One of the branching paths in Guardian Heroes allows you to storm the gates of Heaven and kill God.
 * The Shin Megami Tensei series has this alongside Did You Just Punch Out Cthulhu?, what with being able to fuse gods like Pallas Athena, Vishnu, or Amaterasu and getting them to fight other demons based on deities.
 * Shin Megami Tensei II ends with the protagonist slaying . He pays dearly for this after comes back.
 * Shin Megami Tensei III: Nocturne has the protagonist defeat, a mere avatar of . However, by completing the secret True Demon ending,.
 * The Persona series continues this trend, with the main characters fighting Nyarlathotep, Nyx, and.
 * Arc Rise Fantasia has the main characters kill the god of their world.
 * One ending in Yggdra Union has the eponymous character head to heaven to do just that.
 * Sacrifice sees the five gods of the world dropping like flies as the story goes on: Eldred kills at least two in every campaign, and Marduk inevitably kills the rest. It's explained to you that the gods you killed may return with a new name later as long as there are people to believe in the forces they represent, but the process takes centuries at best.
 * Pretty much the entire point of Kid Icarus is to go from a weakling cherub to badass so you can kill the goddess of darkness and save the goddesses of light. No wonder it's Nintendo Hard.
 * Asura's Wrath has this as well. The Seven Deities started out as Sufficiently Advanced Cyborgs as part of a species known as "demigods" who decided to elevate themselves to full-on godhood by assassinating the emperor and pinning the murder on Asura, then kidnapping his daughter because of her unique ability at controlling Mantra, their power source. Asura is betrayed, his wife is murdered, and he is killed. He comes back, and he is pissed.
 * Elevated to really ridiculous levels with Asura killing
 * Final Fantasy VI has this, as well. The playable characters' kill the three gods of magic; Goddess, Demon and Fiend, in order to bereave Kefka of his magical powers. However, it turns out after the Warring Triad had been felled that Kefka had drained them of so much of their powers, he was sustaining magic by himself, making him the God of magic.
 * And then the playable characters proceed to kill him.
 * Later, in Final Fantasy VIII, if you have Odin on your side when you fight Seifer, he up and kills the poor guy right at the get-go. Fortunately, Gilgamesh shows up to finish him off, taking up Odin's sword.
 * Record of Agarest War 2 has Weiss, the first generation protagonist who kills a god and now must pay the price.
 * The Sinistrals in the Lufia series claim to be gods, and they've got the power to back up that claim. They're also embodiments of evil, so the plot of the games usually revolves around finding the Dual Blade, a sword which can kill gods, and then kicking the Sinistrals' asses with it.
 * In Dungeon Crawl, Gods Need Prayer Badly. Gods without intelligent followers will fade away. This makes it possible to kill . The other gods have enough followers to not be suspectible to this.
 * In Dark Souls, you end up killing all of the deities mentioned in the opening cutscene. Granted, most of them are in pretty bad shape by the time you actually meet them. A few of the other bosses are minor gods as well, but they can be killed like any other enemy in the game.
 * Neverwinter Nights 2: Mask of the Betrayer
 * Overlapping with Did You Just Punch Out Cthulhu?, this is the entire reason the Grey Wardens were created in the Dragon Age 'verse: the archdemons are the slumbering gods of the Tevinter Imperium, awoken by darkspawn. If killed by a normal mortal, they'll come back to life via body surfing to the nearest darkspawn. If a Grey Warden is in proximity, however, it'll jump to the Warden and their souls will mutually annihilate.
 * The second half of the plot of Star Ocean: Till the End of Time deals with the party trying to stop The Creator from destroying the galaxy.
 * Part of the Lady of Pain's backstory is that she once fought the god of portals for control of Sigil and won by killing him. He was not a minor god, either. She then killed everyone who worshipped him and destroyed all written lore about him, leaving only one priest alive (perhaps as a reminder) and killing anyone who thereafter joined him.

Web Comics
"Gabe: They killed their gods. Tycho: Why would they do that? Gabe: To ingest their godseeds."
 * Attempted twice in Bob and George with the Author, who is essentially the God of the comic's universe. At the end of the first game storyline Dr Wily captures and seemingly kills the Author, erasing the comic from existence. It was quickly established the Author was only injured and recovered (at the time this was done because the Mega Man strips were meant to be filler and the Author did intend to stop them, but then wound up going back to them and they became the main story).
 * In the final storyline, Bob attempts the same plan but takes it Up to Eleven by arranging for the Author to get killed in three time periods, ensuring his destruction. When George points out that Wily already tried killing the Author and failed, the Shadowy Author reminds him that since it's already known the comic is coming to an end there's no guarantee Bob's plan will fail this time (it does, but the point is still valid).
 * In Penny Arcade Tycho recommends killing the gods of Gabe's ludicrously powerful Dungeons and Dragons group in an attempt to find something to frighten them. Unfortunately...


 * A major plot point in Digger, though it doesn't come up until late into the comic's run. Interestingly, it's actually a Mercy Kill; the god in question is not the Big Bad, but its victim and host.
 * Sluggy Freelance: The talking sword Chaz can kill just about anything when powered by innocent blood. It claims it could easily kill the Demon King, a God of Evil.

 * Perhaps the ultimate example would be The Salvation War series. The first story has humanity go to war with Hell and win so hard that it is later referred to as the Curbstomp War. Then we kill Satan with cruise missiles. The next story, we go to war with Heaven. The only reason that we don't personally kill God there... well...
