When the "generation gap" turns into rivalry or all-out war between children and adults.

Often goes hand-in-hand with AdultsAreUseless. See also TeenageWasteland.


* This was a pretty common trope in children's advertising during the early to mid-1990s (examples are Frosted Mini Wheats, Hi-C, and even one anti-smoking PSA from 1992/93).

* ''Film/BattleRoyale 2'' goes down this road.
** It also occurred in the backstory of the original.
* ''Franchise/ChildrenOfTheCorn'' film series is an endless parade of cultist children killing adults.
* While it's only two adults and two children, ''Film/LittleSweetheart'' is a prime example. Two bank robber criminals vs. two blackmailing, stalking, thieving little girls.
* The 1968 film ''Wild in the Streets'' has the voting age lowered to 14; the 24-year-old rock star subsequently elected president then has everyone over 30 put in re-education camps.
** The film ends on a punchline suggesting a FullCircleRevolution when the young president pisses off a couple of 7-year-olds.

* "The Grandfathers' War", one of Creator/MurrayLeinster's ''Literature/MedShip'' stories, featured a war between generations (although the younger was of the age of maturity).
* Stanley Kiesel's novels ''Literature/TheWarBetweenThePitifulTeachersAndTheSplendidKids'' and ''Skinny Malinky Leads the War for Kidness'' take this trope quite literally.

* It's certainly been the premise of a couple of {{game show}}s over the years:
** ''Get Your Own Back'' and ''The Kids Are Alright?'' Creator/JohnBarrowman hosts the latter.
** ''The Quiz Kids Challenge''
** ''Series/AreYouSmarterThanAFifthGrader''
** The Nickelodeon sports-themed game show ''Series/WildAndCrazyKids'' frequently used this trope.
* ''Series/TheAdventuresOfPeteAndPete'' had the [[TheOmniscientCouncilOfVagueness International Adult Conspiracy.]]
* Two ''Series/StarTrekTheOriginalSeries'' episodes about conflict/war between kids and adults: "Miri" and "And the Children Shall Lead".
* A majority of Series/KamenRiderGaim is spent focusing on the conflict between the kids (Beat Riders) and the adults (Yggdrasil), however, the sides get skewered as the series goes on. The kids have grown up ideals (fighting for what is right, might makes right) while the adults have childish goals (half of them wanna be an all-powerful being). The conflict between Sid and Kouta perfectly highlights this, as Sid's banters often involves how kids often are stupid and need to be ruled over by their adult superiors.

[[folder:Western Animation]]
* ''WesternAnimation/CodenameKidsNextDoor'' has this as the premise.
* The MusicalEpisode of ''WesternAnimation/TheFairlyOddParents'', "School's Out", has this as a major song, as, how do you say, [[CrowningMusicOfAwesome adults ruin everything]].
* Happens now and again in ''WesternAnimation/{{Recess}}''.
* An episode of ''WesternAnimation/TheSimpsons'' had the adults enforcing a curfew, and the kids rebelling against it by broadcasting all the adults' dirty secrets. [[spoiler:Subverted in that, during the grand finale song-and-dance number, the elderly got in on the fight and won, forcing everyone under 50 to adhere to the curfew, allowing them free roam of the streets.]]
* Some ''WesternAnimation/SouthPark'' episodes have this.
