During a ClassReunion, someone who was picked on, teased or outright abused during their high school years [[RevengeOfTheNerd takes their revenge]] on their (many) erstwhile tormentors, one at a time, and usually fatally. The main character(s) may be mistaken for members of the offending group (or may have been unwitting accomplices), but more often are uninvolved bystanders until the first death. Naturally, the rest of the reunion is spent figuring out who the culprit (and/or who their next victim) is.

A version of [[NastyParty The Nasty Party]]. Often takes the form of TenLittleMurderVictims.

* ''KarakurizoushiAyatsuriSakon'' had one of these involving a school's puppetry club. It's actually the victim's older brother who's the murderer, though it's set up to make the bullies think it's the victim's ghost that's doing it.

* In a ''DonaldDuck'' comic book story, Donald plans to settle some scores with some bullies at a class reunion by training to beat them up. However, Daisy Duck, disgusted at this puerile behaviour, talks him out of it. It turns out that was a good thing considering that Donald learns to his consternation that his former bullies ''still'' tower over him and he would have been way over his head starting a fight.
* In ''Comicbook/{{Empowered}}'', most of the superheroes are outright jackasses who often pick on the D-listers. So it should come as no surprise that one of them finally snapped at a superhero get-together. There's also a NotSoDifferent moment with the title character, who's one of the most pitiful, picked-on superheroes imaginable. [[spoiler: Who proceeds to save all of her jackass co-workers in a CrowningMomentOfAwesome.]]

[[folder: Literature ]]

* Jon Stewart (the same one from ''Series/TheDailyShow'') once wrote a short story involving a man who creates an ArtificialHuman specifically to take revenge on the rest of his class at his high school reunion. On arriving at the reunion, however, the man discovers that almost the entire class had the same idea; aside from a small group of terrified people in formalwear, the reunion has degenerated in a fight to the death between those seeking revenge. He gives up and goes home, monster in tow.
* ''Pawing Through the Past'' by Rita Mae Brown and Sneaky Pie Brown.
%%* Creator/BenElton's ''Past Mortem''
* ''Unsound Variations'' from [[ASongOfIceAndFire George R.R. Martin]] has one of these, though it's not a full high school reunion, the man simply invited three of his sort of friends from high school. Also, instead of being an opportunity for revenge it's the culmination of it. He reveals to them that he invented a device capable of MentalTimeTravel and how he used his knowledge of the future to ruin their lives. His plan to crush them completely like this backfires to about the furthest possible extent. Instead of despairing they gain new hope, since they now know for a fact that they would have been very successful had not a ''crazy time traveler devoted at least two lifetimes to wrecking their careers.'' On realizing this he uses the machine again, which means bad news for an alternate reality them, but at least means he's no longer a danger in their current reality.
* In ''Literature/TheDemonPrinces'' final volume, ''The Book of Dreams'', supercriminal Howard Alan Treesong pays an amusing (for him) visit to his high-school reunion.
* The plot of The DiamondBrothers book ''I Know What You Did Last Wednesday'' is a group of old classmates being invited to a reunion on a remote island being murdered one by one. A parody in that [[spoiler: their only crime was coming first in school subjects where the killer came second]].
* The RomanceNovel ''Endless Enchantment'' had this as the plot. A 10-year class reunion takes place on a cruise ship. The heroine was a reluctant member of a GirlPosse lead by a vicious AlphaBitch in high school. Increasingly dangerous pranks are played on each member of the group until the AlphaBitch is killed. Turns out that a classmate [[spoiler: whose Harvard-bound cousin was the main target of the mean girls. She commmitted suicide after being date raped by the AlphaBitch's twin brother at a graduation party]] is the one who wanted revenge and her pranks mimicked the same things that the girls did to her in high school.

* ''[[TheSeanCullenShow The Sean Cullen Christmas Special]]'' had, throughout the evening, an old schoolmate trying to kill Sean for taking the last place in the orienteering club. But then it turned out that Sean had never joined the club, and the other guy had spent his whole life chasing the wrong man.
* In an episode of the sitcom ''{{Taxi}}'', Louie lets Bobby the actor impersonate him at his high school reunion, playing a handsome "full-sized" version of him and getting (non-violent) revenge on all the class's Beautiful People. "Yeah, I shot up in college. It was written up in all the medical journals."
* An episode of ''[[CSIMiami CSI: Miami]]'' had a football star (and former JerkJock) killed by [[SympatheticMurderer someone who he]] [[spoiler: had cocooned in duct tape and left in a locker, the resulting injuries ruining his life.]]
* ''Series/{{Charmed}}'' once had the Charmed Ones go to their high school reunion where Phoebe was ostracized and mocked for being promiscuous during high school.
* Inverted in the ''DesigningWomen'' episode "They Shoot Fat Women, Don't They?", where Delta Burke's ex-beauty queen Suzanne Sugarbaker is mocked at her high school reunion for being fat. The episode is also a VerySpecialEpisode touching on the topics of weight prejudice and world hunger.
* Subverted in ''TheMentalist'' when its revealed that the killer was not the guy who was a victim of a high school prank.
* In ''Series/{{Frasier}}'', Frasier Crane is absolutely delighted to be able to squire the old alpha cheerleader and then way-out-of-his-league Lois to ''his'' nigh-school reunion ball. But being Frasier, he messes it up.
* ''Series/ItsAlwaysSunnyInPhiladelphia'' has a ClassReunion two-parter episode. Dee mingles with the old popular clique. She says she's infiltrating their group to get revenge on them, when it's clear she's just happy to be popular for once. So the rest of the gang try to get revenge without her. [[spoiler: The clique later kicks her out for sleeping with Rickety Cricket which she didn't do. Then the whole gang get their revenge together and fail at it twice.]]

* Horrible, horrible version in ''{{Exalted}}'' - one of the Deathlords, Eye And Seven Despairs, was DrivenToSuicide during his life as an Exalt by the rest of his Circle. He's since developed a twisted obsession with tormenting the Shards they were bonded to (of which he has three of the four) that is occupying significantly more of his attention than his actual job, namely destroying the world.
** To the point where TheStarscream is looked upon as higher on the totem pole then he is.
** Also, in ''Exalted'', Autochthon built the Exalted so he could kill his brothers and sisters that picked on him and destroyed his inventions. So he creates the Exalts who kill the other Primordials, or [[AndIMustScream mutilate them and imprison them in their king's own body.]] Talk about overreaction. Of course, given how dickish they really were, this is not that monstrous, from a certain point of view.

* Helen B. Narbon plans to pull one of those during her high-school reunion in the webcomic ''{{Narbonic}}''. However, it is eventually revealed that people didn't shun her due to disliking her - they avoided her because they were scared stiff by her easy access to [[MadScientist mad science]]. Faced with this realization, Helen decides not to turn them all into gerbils after all...

[[folder: Western Animation ]]

* ''KimPossible'' had a variation on this. In "Attack of the Killer Bebes", Doctor Drakken (formerly Drew Lipsky) used three robotic women to kidnap three of his former college buddies, who had made fun of Drew's extremely junky "Bebe" prototypes in the mid eighties. One of the targets was Kim's father, Dr. Possible, but he failed to make the connection to his teenage arch-nemesis. He was spurred into action by the invitation to the upcoming reunion, and held them hostage at the reunion hall.
* One of ''WesternAnimation/DarkwingDuck'''s many origin stories was remembered when Megavolt attempted revenge on the bully and the cheerleader that not only made fun of him (and bullied Drake Mallard as well), but trapped him in his experiment which ended up giving him his powers. (And theoretically frying his brain, or he might have just snapped on his own. Hard to say.) At a reunion, Megavolt tries again at a class reunion against the two bullies, who are still as contemptuous as ever. He is stopped by Darkwing and Gosalyn and the bullies learn Darkwing's true identity and are deeply impressed that Drake is a superhero. Although they promise to keep his secret, Darkwing decides to guarantee that by hypnotizing them to forget the fact while instructing them to treat Drake Mallard with some respect.
* ''WesternAnimation/BatmanTheAnimatedSeries'' villain Mary "Baby-Doll" Dahl kidnaps her former costars, but just to force them to go through the motions of the show. Except for [[CousinOliver Cousin Spunky]], whom she attempts to kill with [[StuffBlowingUp dynamite]]. (Who wouldn't?)
* ''DannyPhantom'' BigBad Vlad Masters throws a reunion to get back/murder his former best friend (who has no idea and still likes him, ironically) in order to win his best friend's wife. Thankfully, that oblivious man's son is... DannyPhantom.
* ''WesternAnimation/TheVentureBrothers'' Mike Sorayama, an old college classmate of Doc's, dies and has his designated pallbearers (Doc, Brock, Pete White and Baron Underbheit) kidnapped. They get locked in a dungeon and learn that Sorayama was FakingTheDead and wants revenge for petty slights, all related to his one-sided crush on an attractive classmate. Underbehit tricked him into smoking cloves, to which he was allergic, making him miss a study date; Pete, the campus DJ, played an embarrassing fake dedication; Brock beat the crap out of him (and everyone else) in a drunken rage after getting kicked off the football team. [[spoiler:In the end, it turns out that Sorayama really ''is'' dead, and the one carrying out the revenge was just another of his lifelike robots.]]
** It's even worse for Doc; as near as he can recall, all he did was seduce a monster based off the girl in a ''DungeonsAndDragons'' game that Sorayama was [=DMing=]. Sorayama's real reason was that [[spoiler:he thinks Rusty actually slept with the girl; he didn't, but Brock did, and he jumped to conclusions when he saw her emerge from Doc and Brock's dorm room]].
* ''JohnnyBravo'' has combined this with ShesAllGrownUp: Johnny wants to take revenge on a girl who always made fun of him when they were kids but it turns out that she turned into a total babe. The rest of the episode is spent agonizing whether she likes him now or she's just playing a prank on him like she used to. [[spoiler: [[FailureIsTheOnlyOption It's a prank]].]]
* In "Bully For Parker", an episode of ''WesternAnimation/ProducingParker'', the main character plans an elaborate revenge for her high school reunion, but has second thoughts when she spends some time with her most vicious tormentor.
* ''WesternAnimation/DanVs'' "The High School Reunion": Dan, [[RevengeBeforeReason being Dan]], tries to get revenge on his old classmates because he felt high school was just constant ridicule. [[spoiler: It turns out Dan was popular because his over-the-top revenge schemes were very entertaining. Instead Chris was the unpopular one out of the duo. So Chris decides to get revenge. But they think it was all a part of Dan's plan which makes Dan even more popular.]]

* Bas Rutten, former [[http://www.wrestling-titles.com/mma/ufc/ufc-h.html [=UFC=] World Heavyweight Champion]] and [[UsefulNotes/MixedMartialArts [=MMA=]]] Legend, was actually physically weak in High School and bullied often. When he came back for a school reunion he was a highly decorated fighter and challenged his former bullies to a fight. They all declined.
