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. 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.

Ace Combat

 * No Chute - Agent Sergio Turbo destroyed Thunder 2's parachute after he ejected from his locked-on plane. Attacking an ejecting pilot is a war crime outside badfic, but in this case was acceptable due to targeting a Stu.

Animorphs

 * Black Hole - Used by Agents Tangara and Tawaki against Forlay.


 * The mantle of the Hork-Bajir world - Used by Tangara and Tawaki against Gem Stoned.

Avatar (film)

 * Pandora's Atmosphere - Agent Florestan charged a replacement of a Nausicaä of the Valley of Wind canon by charging her as she was breathing in the atmosphere of Pandora. This killed her just after he finished going through the charge list.

The Bourne Trilogy

 * Shot in the throat - Used by Agent Kitty Callahan against Helen Johnson. Notable because it is the canonical method of assassination by the books' antagonist, Carlos the Jackal.

Call of Duty

 * M1006 Sponge Tipped Less-Than-Lethal Round - used to nonlethally subdue Specialist Anna Noname so she could be charged by private security contractor Pam Ritchie and DoSAT agent Techno-Dann.

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.


 * Assassin's Guild receipt - a handy excuse for leaving bodies lying around in Ankh-Morpork, used by Dafydd and Vemi to explain away the corpses of Lascivia Sto-Helit and a Hogfather impersonator.

 * Giant Fireball - Deployed by Agent Alec Troven on a co-mission to take out the uncanonical Lorram's Smith and the Mary-Sue and bit characters inside it. Him. Whatever. It was gross.

Fahrenheit 451

 * Flamethrower - Agent Vania felled Uncle Mo with one before portalling him into the Big Flue.

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.

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.
 * 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.

 * Long Way Down with a Splash - Agents Chliever the Corroder and Winston Chalmers tossed a stu!Harry and stu!Draco, as well as randomly placed stu!Frodo and stu!Sam from the top of the Astronomy Tower and down to the lake.
 * Mauling by Drake - Agent Drake was inspired by Makes-Things' discussion of kumiho and tore out the liver of Princess Rikai.

 * Quintaped - Employed by Agents Tawaki and Melpomene against an unidentified daughter of Merlin and Ravenclaw.

 * 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.

 * Warg disguises - Employed by Jaster, Threnody, and Harmony against Honesah.

 * Burbot - Nin Brandt and Luxury threw Streamflower into the burbot stream after her emergency C-section.


 * Canon Catapult - 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 (eg "ugly, craven and stupid"). Also used by Laburnum and Foxglove for bulk killing of a noncanonical vermin horde.


 * Disembowelment - Agent Jill is a werewolf, and used her wolf form to maul Zain and Darkhan when on a mission with Agent Redd. The body, the co-star Sue Nakia, and the building they had been in were then destroyed with a replica of Discworld's "Piecemaker" weapon.

 * 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).

Warcraft/World of Warcraft

 * Bringing down the hammer - Agent Brightbeard used his large, metal warhammer to do this literally as well as figuratively on Sharya of the Crimsonpath Clan.


 * Canon crossbow - Agent Renée Garrett shot Vindicator Alexei (AKA "Vindicator Spring Goddamn Sky") twice with an Emberhawk Crossbow (and then cut his throat to make sure).


 * Industrial marking pen - Agents Renée Garrett and Phoebe Claypool used this to write "DRAENEI-LOVER!" and a charge list on Gaerien (AKA "Mr. Nice Demon") before porting him into the immediate vicinity of Kil'jaeden the Deceiver.


 * Removal of deus ex machina - With neither of her two associated Marty Sams around to rescue her, Anchorite Ranith (AKA "Anchorite Tsundere") was left dying of a poisoned arrow wound as the Suefic starring her was deleted.

Miscellaneous Other

 * 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 X - Tore Vearanniel apart with a maximum of pain and suffering.


 * The cold storm from "Annabelle Lee" - employed by Agents Suicide and Ithalond to kill Anna-Belle Dialer.


 * Drip Tiberius Rat - demonic personification of Lust from the webcomic Jack. Jackson Earl Simon was given to him by Agents Laburnum and Foxglove. Shortly afterwards, Drip was forbidden as an execution method and Laburnum and Foxglove were placed in therapy yet again.


 * Fed to Mini-Balrogs - Agents Daffyd and Selene fed Alumia to fourteen mini-Balrogs she created and the two that belonged to Daffyd and fellow DOGA agent Takua.


 * Flames - the PPC-verse version of flame emails, which actually are literal flames. Employed by Agents Jay and Acacia to kill Ariuella Shadowfox.

 * Given to the Discworld Elves - Agents Jay and Acacia used this method to eliminate a particularly awful Arwen!Sue.


 * Hobbers - worshippers of the rat god Hobb in Robin Jarvis' Deptford Mice books, known for skinning sacrificial victims alive in a process known as the "bloodybones." Used by Agents Laburnum and Foxglove to kill Mariel Sue.


 * Masturbating - suggested by Agent Drake as a way to kill feline Sues ("Naomi says God kills a kitten every time I masturba-") during "For Your Eyes Only," a squick-laden fic in which the Naruto characters were transformed into hermaphroditic kittens. 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."


 * The Jaunt - from a 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.


 * Puff of Logic - after Agent Supernumerary pointed out that Reicheru Ketsuekineko-oni's existence was founded on an unstable time paradox involving her being the mother of God, she and her spawn promptly ceased to exist a la Douglas Adams.


 * 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.


 * Redneck Trees - of the webcomic Something Positive. Talking trees which use their roots to... you don't want to know. Employed by Agents Laburnum and Foxglove (Stormsong and Skyfire were present, but deny all responsibility) to kill two Pointless Rapist Bit-Characters by the names of Raketooth and Crabclaw from a Redwall fic. Officially forbidden as an execution method shortly after they used it.


 * Slit Throat - For expediency's sake, Agent Glass slit the throat of Morgain after detaching her from Don Pedro. The corpse was disposed of on the battlefield outside Dunsinane.


 * Springfield Tire Fire - Used by Suicide and Ithalond against Springfield.


 * "Trampled to death by a rabid Led Zeppelin audience" - employed by Agent Trojanhorse to dispose of Kasia and Elleelen.My Little Pony to the list
