Assassination Methods

An assassination method is one of many different ways to kill a Sue, ranging from the classical arrow to the chest, to the more creative method of pitting them against another Sue with a similar description. This is an incomplete list of those methods, as listing all sorts of banal assassination methods (Pointy Objects, guns, pushing Sues off high places, etc.) is a waste of space and time&mdash;we'd have to list every time an agent broke a Sue's neck. They are classified by the continuum in which they took place, usually but not always the continuum of the badfic. Assassination methods which are closely in line with what could happen in canon tend to be more effective at getting the continuum to revert to its normal state.

Assassination is not the same thing as murder; not all Sues are killed (if they are not a danger to the existence of the Multiverse, Sues can be recruited).

Note: Some methods involve feeding the Sue to a canonical monster, and hungry beasts are often considered a neat way to dispose of the bodies regardless; agents should be aware that Upstairs does not approve of this method being used too often, as it is liable to leave the canonical monsters uncanonically fat.

Black Butler

 * Knifed in the back, then in the heart - Courtesy of Violet Rose Greenfield and Miguel Correa. Notable chiefly because the Sue in question had multiple supernatural heritages; she "chose" none of them and was therefore vulnerable to conventional weapons. (Also, she was weak from supposedly having had her soul eaten anyway.)

Death Note

 * Everything note and Sentient Fire - Velociripper used a Stu artifact to persuade a "magic fireball" to burn Dark Yagami to death on his second mission. He ate the charred corpse after completing the mission.

 * Also used by Agent Navare, who dropped a Stu on the Book of Darkness' Berserk Defence Programme right before it was annihilated by the Asura.
 * Fire hose, Mermaid karaoke, Arc-en-ciel and Earth-Shattering Kaboom - This odd combination was used by Sergio Turbo, Nikki Cherryflower, Ari, Tera and Corolla to kill the incredibly overpowered Alyxx Heart: she was weakened with water and a high pitched song (her two weaknesses according to the fic), then she was left on an uncanonical planet, charged, and killed with an Arc-en-ciel blast that also blew up the planet itself.
 * Stabbed with bad writing - Agent Tera threw 'stabs of fear and jealousy' through five bit characters and a Sue-wraith.

Monster Musume

 * Suu and mini-Suus - Provoked into eating a Stu!Alex Mercer by Valon Vance and Kala Jeng.

Naruto

 * Fed to Mini - Agent Cadmar subjected a Sue to the wrath of a mini-T. rex she'd been using as a shoe.

 * Devoured by the Kraken - Agent Lapis convinced Captain Davy Jones to sic his pet on the Stus Titus and Christopher Sparrow.
 * Drowning - Agents Mara and Isaiah allowed Bo'sun to punch Lauren Sue over the side of the Pearl. The broken/cracked ribs caused by the punch ensured that she didn't stay above water for too long.
 * Given to Agent Shmuckleigh - Agents Mara and Isaiah gave Shay Leigh Turner to Agent Shmuckleigh, who happily disposed of the Sue that dared steal her name.
 * Port Royal citizens - Tiernan, James, Phil, and Amanda were tarred and feathered and set loose in Port Royal where the citizens dealt with them for proclaiming, rather loudly, that they were pirates.

Star Wars

 * Blorash Jelly - Intern Hul destroyed OOP-937 with blorash jelly.

Discworld

 * Agatean Thunder Clay and Klatchian coffee - used by Agents Manx, Shadow, and Jill Greenleaf to kill Angua Sue. They strapped her to an activated barrel of Thunder Clay, force-fed her the coffee, and threw her over the edge of the Disc. Klatchian coffee, according to Jill, "strips away the fluffy pink clouds that protect the human mind. And Sues are practically made of those little delusions and plotholes and excuses." Therefore, it causes them to disintegrate. The Thunder Clay exploded before Angua Sue fully disintegrated, thus winning Shadow the five-dollar bet.

 * Auditors - employed by Agents Dafydd and Selene to dispose of Al.
 * Elves - employed by Agents Jay and Acacia for removal of an Arwen-replacing Sue.

Harry Potter

 * Acromantula - Agents Tawaki and Tadkeeta fed Megan Dumbledore to them.

 * Also used by The Aviator, Zeb, The Detective, and Jack Riggs to dispose of a Doctor's Daughter!Hermione Sue.
 * Killing Curse - Supernumerary used Avada Kedavra on a vampiric replacement of Luna.
 * Knockturn Alley - the Sues Maddie and Terrah were immune to magic, and therefore couldn't be restrained or killed with spells. Agents Naomi, Laburnum, and Foxglove killed them with a non-magical axe and sabre, then dumped the bodies in Deathly Hallows-era Knockturn Alley, where nobody would be surprised to find the mangled bodies of two Muggles.
 * Given to Greyback- Agents Rina and Randa fed Ordellya to the werewolf. And his entire pack.
 * Lethal injection - Agent Supernumerary injected a concentrated salt solution into a nerfed!Snape doppelgänger in his first mission with Agent Ilraen. There was a lot of twitching.
 * Misspelled spell - Lord Voldemort used the "Crutacious Curse" on Cordelia Driscol, turning her into a sort of shell-less crab thing. Agents Supernumerary and Ilraen took advantage of it in their first mission.
 * Nundu - William and VJ threw their target into the house of Eldon Elsrickle and let his pet Nundu have a high-glitter breakfast..
 * Quintaped - Employed by Agents Tawaki and Melpomene against an unidentified daughter of Merlin and Ravenclaw.
 * Spider Swarm - Agent Valon Vance, although partially incapacitated through sheer squick, managed to direct a swarm of mini-Aragogs to attack replacements of James and Lily Potter in his incredibly strange fourth mission.
 * Whomping Willow - employed by Agents Jay and Acacia to remove a Sue named Serenity.

The Jaunt

 * The Jaunt - from the Stephen King short story. Used by Agents Laburnum and Foxglove to remove a Lisa Simpson Sue. Evidence suggests the Jaunt disassembles the body on a molecular level while leaving the brain alive to experience an apparent eternity with no outside input, which generally annihilates the sanity. If set to Nil, the body is not reassembled at the other end, thus making it a perfect body disposal system.

The Lord of the Rings/The Hobbit

 * Ancalagon the Black - Smauglock!Stu thought that challenging the biggest dragon in literature was a good idea. Ancalagon, whose breath happens to be a yardstick for the One Ring's indestructibility, wasn't terribly impressed.
 * Balrog - employed by Agents Jay and Acacia to kill Anirana and Hanae.
 * Burning - Agents Jay and Acacia burned down the noncanonical area of woodland in which a Sue named Pangaea was standing. Also used by Agents Dafydd and Selene to remove the noncanonical village of Hasland, along with Amariel Halfelven and Theaden of Lórien.
 * Burning of the Telerin Ships at Losgar - Threndodale and Merrisil, two Stus who claimed to be the Heir of Fëanor, were handed over by Logan and Entropy to the real Fëanor for punishment, and ended up burning along with the white ships (and possibly Amrod, depending on which version of canon you follow).
 * Cracks of Doom - employed by Agents Jay and Acacia to kill Alex and Charlie.
 * Crebain - employed by Agents Jay and Acacia to dispose of Akasha.
 * Draugluin - Logan and Entropy fed Jeneste, a Thuringwethil Replacement!Sue, to Draugluin and the other werewolves in the pits of Tol-in-Gaurhoth.
 * Eye of Sauron - Lady Roselyn Drakeheart gave herself the ability to enter the movieverse shadow world without the aid of a Ring. Sauron very kindly demonstrated to her why this was a bad idea.
 * Falls of Rauros - Agents Logan and Entropy disposed of Listala over the Falls, who wanted to end up dead with her erstwhile love, Boromir, on his funeral boat. She got her wish, more or less.
 * Geographical expansion - Agents Dafydd and Selene were forced to take on "legolas by laura", in which Mordor is suddenly two hundred yards away from Mirkwood. They fixed this by tying the Sue's arms to a rock in Mordor and her legs to a tree in Mirkwood, then knocking her out, allowing the canonical distance to snap back.
 * Also employed by Derik and Gall to punish Vanya for forcing the Anduin to come close enough to the Misty Mountains for her to drop straight in after falling off a broken ledge.
 * Glaurung - the dragon. Used by Agents Jay and Acacia to destroy Elvira Magiseer and Silavren Silvereyes.

 * Orcs - employed by Agents Jay and Acacia to dispose of Phoenix.
 * Orthanc - Agents Jay and Acacia threw Alexis Moonbeam off the tower's roof.
 * Poison - Agent Constance Sims forced poison down the throat of Imarátoiel, who had mentioned that she wanted to be dosed. You should really be careful what you wish for, especially if you are a Sue being hunted by PPC agents.
 * Ring of Sairalindë - magical ring taken from a Sue, used by Agent Dafydd to destroy Celebrian and her orcs.
 * Sacrificed to GreyLadyBast - Evelyn Sue was brought back to HQ after Shadowfax declined the opportunity to kill her for placing a saddle and bridle on him. Agents Mara and Isaiah then allowed her to be used in the initiation of Agent Miiro.
 * Sea - used by Agents Jay and Acacia for bulk disposal of Deminica and her eight co-Sues (Arond, Mianatis, Galami, Shirlia, Carenada, Adromeda, Lanalei and Kylina).

 * Stalagmites - Agents Mara and Rosie impaled Felina on stalagmites in Aglarond.
 * Tevildo - Agents Jaster and Threnody fed a You!Sue to him.
 * Torture - Agent Cassie Young used this method on an illegitimate Aragorn and Arwen's Daughter!Sue. It took rather a long time and the job had to be finished off by Nat Freidar. This particular method of execution was not regarded with favour by the Flowers.
 * Ungoliant - Agents Tadkeeta and Eclectica fed Vanyáliel to her.
 * Watcher in the Water - employed by Agents Jay and Acacia to dispose of Laurel.
 * Witch-king - employed by Agents Dafydd and Selene to kill Sairalindë. Apparently the Witch-king did not recognise her as his daughter, despite her claims to this status.

 * Burbot - Nin Brandt and Luxury threw Streamflower into the burbot stream after her emergency C-section.
 * Canon Cannon - used by Agents Mara and Isaiah to purge Sampetra of the influence of Rinj. It didn't kill her, but it did turn her into a normal corsair rat rather than a Sue (e.g. "ugly, craven and stupid"). Also used by Laburnum and Foxglove for bulk killing of a noncanonical vermin horde.
 * Gloomer - employed by Agents Nin Brandt and Luxury for convenient disposal of Tsarmina Sue, a.k.a. Tsuemina.
 * Ruggan Bor with a sabre - pointed at Rosebay Willowherb by Agents Manx and Shadow. Exactly what he did will be omitted for reasons of good taste.
 * Salamandastron - employed by Agents Laburnum and Foxglove to dispose of Cregga Sue and Bladestripe. This may sound odd until one considers that Salamandastron is an extinct volcano, and therefore if one portals back in time far enough, at some point it must have been active...
 * Skrabblag - employed by Agents Laburnum and Foxglove against Mariel Sue.
 * Teeth of the Deeps - employed by Agents Naomi and Drake to dispose of Fernflower.
 * Yo Karr - employed by Agents Laburnum and Foxglove for bulk disposal of Katie, David, Jessica Jenks, Jessica Clark, Jane, Heather, Chris and Logan (also known as Tigerlily, Aggron, Crystallyn, Jane, Yeather, Dixon and Tollaw - or possibly Tallow, it changed at random moments).

 * Fire Lord Ozai - Convinced by the Aviator and Zeb to fry Zuko's uncanonical girlfriend to a glittery crisp.
 * Koh, the Face Stealer - Agent Rayner introduced "Avatar" Keyx to this denizen of the Spirit World; after Koh stole the Stu's face, the latter was brought back to the mortal realm and, with no nose or mouth to breathe with, promptly died of suffocation.

Farscape

 * Mostly Dead - Agents Supernumerary and Ilraen left the useless, non-canon wizard Dr. Jenkins frozen in stasis on the Diagnosan's planet in the Farscape continuum. He'll remain there until he can serve a purpose as an organ donor, at which time he will become all dead&mdash;unless the Scarrans destroy the facility first, in which case he'll still die. It's a win-win situation.

Firefly

 * Reavers - Agents Rez and Flip portalled River!Sue to a reaver ship. Killing Sues this way was officially forbidden soon after.

Heroes

 * Dropped off the Empire State Building - John Stu was dropped off the roof of the building, hogtied, by Agents Titus and Murtagh.

 * Thrown into a volcano - Used by Dawn McKenna and Zeb against Tigerlily.
 * Mass exorcism - Because the Stu Aaron couldn't be killed directly due to being undead and constructed out of plants, Zeb, The Aviator, and many other agents killed him by exorcising the Everfree Forest. This worked because the Everfree Forest was where the plants came from that made up his body.
 * Teleported into a star - Used by Randa Roan against Midnight Moon, as poetic justice because Midnight claimed to be the Princess of the Stars.
 * Teleported into the Gauntlet of Fire - Used by Ix against Misty.

 * Dissection - Eledhwen and Christianne gave one of their Mary Sues to the incarnation of Sherlock Holmes from the Modern Baker Street Fanfiction Academy. He used her body for science.

 * Partial assimilation and recycling - The Gary Stu, Jack Russel, brought the former upon himself with his own bad logic. Agents Cyba Zero, Eagrus Khan, and Sigma One and Phi Six, gave him the choice of them leaving the process to finish or expelling him from the continuum by death. He did not want to be left to become a Borg drone, so he became resources for the Borg instead.


 * Gun and Vidiians - The Sue Noel was shot dead by Tasmin Haynes and subsequently given to the Vidiians so that they could harvest her organs.
 * Strangled by necklace - The Joanna McCoy Sue was killed by Sedri, who pulled the necklace she was wearing while Sedri's partner, Marsha, held the Sue in place. The body was unceremoniously thrown into the Enterprise 's rubbish disposal unit.
 * Pre-Reformation Vulcans - The Sue Seraphina and her boyfriend Stupock (a character replacement for Spock) were killed by Vulcans from before the Reformation of Logic after Christianne Shieh and Eledhwen Elerossiel threw them both back in time. They did this as a form of poetic justice, since Stupock behaved similarly to a pre-Reformation Vulcan.

Stargate SG-1/Atlantis

 * Fed on by Todd the Wraith - Miah Arthur and Cali Still released Todd the Wraith from the plot hole Dawn the Wraith Lover!Sue had trapped him in for months. Understandably, he was hungry, and more than a bit annoyed with her.

Teen Titans (cartoon)

 * Shot into the sun - Agent Rashida disposed of a vampire Stu by sending him through a portal and into a solar flare.

Ace Combat

Dragon Age

 * Panties - After being rescued by Agents Aster Corbett and Lore, the mage Bendrick smothered Lucy-Elissa with her own panties, electrocuting her for good measure.

Dragon Quest

 * Bad Jokes - Aided by Ray Chell, Aster Corbett told a number of bad jokes to a trajeck orphan Mary Sue. The Sue exploded, unable to survive in a lighthearted environment.

Fallout

 * Iron Smelter - 6 sweetwater was dropped into one of these in The Pitt by Danny, Laura, and Intern Rachel.

Final Fantasy

 * Strangulation - Agent Arti strangled an Impostor!Stu with the towel he had worn into the mission. The body was then dumped in the Halo-verse (the part where multiplayer matches take place in, apparently), where it was shot at 30 times and subjected to the "usual treatment" employed by the victor (i.e., teabagging).

Five Nights at Freddy's

No Rest for the Wicked

 * Red - of the webcomic No Rest for the Wicked. Hates "clever beasts" and therefore was a perfect execution method for the Cluny replacement of That Series, whom she chopped up with her axe, despite the fact that "clever beasts" was stretching a point with that particular character replacement. Used by Agents Manx and Shadow.

PPC-related

 * Agent Chakkik - Killed a replacement of Lord Voldemort with his acidic breath. He used the same means to dispose of the body of Chloe Riddle, the primary Sue, who had already been slain.
 * Agent Luxury - employed by Agents Jay and Acacia to dispose of the corpses of Aislinn the unicorn and Link. Best not to ask what she does with them.

 * Agent Velociripper - Devoured a pathetic, demeaning character replacement of Ash Ketchum.

Officially forbidden as an execution method shortly after they used it.

 * Frustrated villain - Big Brother was none too pleased when Lossenlindëiel failed to retain a segment of the Key to Canon.

Vetoed by Naomi, Stormsong, and Skyfire on the grounds of good taste and the fact that "If you're physically capable of doing that after seeing this fic, you need professional help."
