There may be no more unfortunate age to turn than sixteen, especially if you're female, although in all media [[SpearCounterpart male examples exist too]]. While there are dangers inherent in simply existing, celebrating one's sixteenth birthday is one of the most obvious. Generally, this entails the [[PubertySuperpower manifestation of powers]], possibly some AncientConspiracy or prophecy, and the end of a "normal" life for the character in question. GrowingUpSucks.

There are some Real World reasons why 16 is often chosen as The Age At Which [[PrecisionFStrike Shit]] Happens. Although the hormonal hell known as puberty actually started a few years earlier, sixteen tends to be when the teenager finally has those changes under control and starts to act (somewhat) more like an adult, which is reflected in how teenagers' bodies sexually mature (on average) by 16; thus, in many cultures, 16 was the effective age of majority. Even though Western culture prefers to wait until 18 to confer legal adulthood, in the U.S. 16 is still the minimum age for a driver's license and many types of employment (both very important milestones of adulthood, independence, and/or general social status). 16 is actually the official age of consent in 31 states. [[note]] Pennsylvania, despite having it at 16, in practice, has it at 18; several states allow loopholes for 15 or 14 year olds; and several other states have provisions that allow 16 and 17 year olds to consent to sex with adults under 23.[[/note]] On the flipside, in many jurisdictions 16 is the minimum age at which a minor accused of a crime may be tried and punished as an adult rather than through the juvenile justice system. And in Asian media, let's not forget that 16 is [[FourIsDeath four times four]].

From a media perspective, 16 is also a transition age from works specifically intended for tween/teen consumers towards the mainstream adult audience. Notice, for example, how in the ''Literature/HarryPotter'' series each year's installment is noticeably darker and aimed at a higher reading level than the last, with Book 6 marking the point at which the writing style and tone become level with mainstream adult fantasy novels.

Subtrope of Main/LiminalTime. Often overlaps with TheHerosBirthday as the ''precise'' moment at which everything hits the fan.


[[folder:Anime & Manga]]
* Aya Mikage in ''Manga/CeresCelestialLegend'', who first manifested the powers of the ''Tennyo'' (Celestial Maiden), Ceres, on her 16th birthday. In one of the rare examples of this trope afflicting a male, her twin brother, Aki, also begins exhibiting certain supernatural traits after this date. Essentially the whole of the Mikage family is perpetuating an AncientConspiracy based on these events.
* Tiala inherits the Red Stone on her sixteenth birthday in ''Anime/DragonQuestLegendOfTheHeroAbel''. She is kidnapped for it the same day.
* ''Manga/KannazukiNoMiko'': Kurusugawa Himeko and Himemiya Chikane gain their powers as the priestesses of the sun and moon on their 16th birthday, the same day that [[{{Orochi}} Yamato no Orochi]] first manifests and begins its attempt to destroy the world.
* ''VisualNovel/YamiToBoushiToHonNoTabibito'': A relatively calm use of the trope, Azuma Hatsumi (Eve), who simply disappears from any world she enters upon turning 16.
* ''Anime/DevilHunterYohko'': The title character comes into her own on her 16th birthday.
* ''Anime/{{Yumeria}}'': Tomokazu Mikuri finds himself thrust into the (sometimes hilarious) war in the world of dreams starting the night before his sixteenth birthday.
* In another male example, when Yuuto Amakawa of ''Manga/OmamoriHimari'' turns sixteen, the ProtectiveCharm that was sealing his powers and making him invisible to demons stopped working, making them aware of his presence. At the same time arrives his samurai catgirl bodyguard, Himari (followed shortly thereafter by the rest of the UnwantedHarem).
* Pacifica from ''LightNovel/ScrappedPrincess'' is destined to cause TheEndOfTheWorldAsWeKnowIt on her sixteenth birthday.

* In ''Manga/BlackBird'', Misao becomes a "bride of prophecy" on her 16th birthday.
* ''Manga/VirginRipper'' (meaning [[GrimReaper a young "reaper"]], not a serial killer of virgins): A year early, but it's implied that on Hotaru's 15th birthday [[spoiler: she allowed herself to die (essentially suicide, and only suicides become reapers) so the "real" Hotaru she was cloned from could get her organs, hence why her soul is different from the other reapers]].
* The local villagers in ''Manga/{{Maomarimo}}'' offer their annual "maiden sacrifice" to the marimo spirit on the maiden's 16th birthday. Fortunately for the girls it's a purely symbolic sacrifice that mostly involves spending the night alone in a boat on a lake. Everyone thinks it's just a quaint local custom until the hero, a 16 year old male virgin, takes his twin sister's place and [[GenderBender gets turned]] ''[[GenderBender into]]'' [[GenderBender a maiden as a result]].
* ''Anime/CrossAnge'', Ange on her sixteenth birthday loses her mother and is later exiled to a PenalColony.

* In the DCU, Franchise/{{Batman}} [[IDidWhatIHadToDo ruthlessly]] manipulated [[Comicbook/{{Robin}} Tim Drake]], the current Robin, into believing [[HeWhoFightsMonsters the fall of one of their friends]] would result in a BadFuture ten years down the line, effectively alienating Tim from everyone else.
* The premise of the series ComicBook/DarkChylde is that the main character develops the ability to become monsters from her nightmares starting at age 16.

[[folder:Fairy Tales]]
* Even though ''Literature/SleepingBeauty'' is the TropeCodifier in popular culture, different versions of the tale vary on whether they use this trope or not. In Charles Perrault's 1697 version, the princess is cursed to prick her finger and fall asleep at any time, but it eventually happens when she's sixteen, though not specifically on her birthday. In the Brothers Grimm's 1812 version, the curse comes to pass on her ''fifteenth'' birthday. Most retellings combine the two versions, though, and have her specifically cursed to prick her finger on her sixteenth birthday.

[[folder:Films -- Animation]]
* Subversion in ''Disney/SleepingBeauty'': "The princess shall indeed grow in grace and beauty, beloved by all who know her. But... before the sun sets on her 16th birthday, she shall prick her finger, on the spindle of a spinning wheel - AND DIE!" So her 16th birthday isn't ''the'' most dangerous day, it's just the last day for the curse to take effect.

* A variation in ''Film/WeNeedToTalkAboutKevin'': although it's foreshadowed as a crucial date several times, Kevin actually [[spoiler:commits the high school massacre]] a few days ''before'' his 16th, which his mother assumes was a deliberate attempt to get himself [[spoiler:tried as a juvenile.]]

* In the ''Literature/PercyJacksonAndTheOlympians'' series, there is a prophecy known to apply to whichever child of the three major gods next reaches their sixteenth birthday. [[spoiler:This leads to several fake-outs regarding who the child is. At first Percy, as the son of Poseidon, is the only candidate, until Thalia, a daughter of Zeus who had been turned into a tree, is re-transformed. However, the day before Thalia's birthday, she joins the Hunt of Artemis, meaning that she [[ReallySevenHundredYearsOld will never age]] and thus will not turn sixteen.]] After, [[spoiler: the prophecy is more-or-less a race to see if the Titans can kill Percy and sway the ''other'' other candidate, Nico di Angelo, son of Hades, to their side, or if they can cross their fingers and hope he screws up - badly - at decision-time.]] In the end, however, [[spoiler:while Percy makes the decision, it boils down to deciding whether or not to give someone a knife, and his sixteenth birthday ends up only as a time marker. The one who takes the "dangerous" part of the prophecy ends up being someone entirely different]].
* Creator/JackLChalker's ''Literature/HorrorsOfTheDancingGods'': Both Lampshaded and Averted as a sign of the generally high level of intelligence endemic to the setting: The heroine quizzes the LivingMacGuffin about her birthday before she realizes that the girl (who has been kept in hiding for nearly her entire life) probably doesn't even know her real birthdate anyway.
* ''Literature/DeltoraQuest'' (and it's anime adaptation) has Lief beginning his quest to find the seven gems to free Deltora on his sixteenth birthday.

* ''Literature/TalesOfTheFiveHundredKingdoms'': A force known as "The Tradition" attempts to make people play out their lives as if they were stories, and one of the big turning points of The Tradition's power is one's sixteenth birthday. As a Princess in one of the books reflects, if you're plain, everyone will forget your birthday and you will be miserable; if you are beautiful everyone you meet will celebrate with you. How the birthday goes can determine your life's path.
* In Scott Westerfeld's ''Literature/{{Uglies}}'' series, people get the pretty operation at 16 (though it is mentioned to the later in some cities).

It is also mentioned by Tally that it was said "they could make the operation work on 15-years-old now, waiting until sixteen was just a tradition".
* The parodic comedy ''Literature/HowToSurviveAZombieApocalypse'' features the main character's sixteenth birthday as the same day the outbreak started.
* In the book ''XVI'' by Julia Karr, sixteen is when girls get their 'XVI' tattoo and can legally have sex. Of course, that's not necessarily a good thing...
* Sixteen is the age of marriage in the world of ''Literature/ABrothersPrice''. Men are rare, so they get married right on their birthdays or soon after. For women marriage can happen at any age, even before birth - because a man marries every sister in a family - but the age of consummation for them, too, is sixteen. This birthday is more dangerous for men, who have to leave home to live with new families.

* ''Series/TerminatorTheSarahConnorChronicles'': The first season finale takes place on what would be John's sixteenth birthday, except they [[spoiler: jumped ahead eight years in the pilot]].

* In ''VideoGame/FinalFantasyIX'', a Summoner's sixteenth birthday makes them into an easy power source for the forces of evil.
* ''VideoGame/DragonQuestIII'' opens with the hero's 16th birthday -- the hero can be male or female. Since their father didn't finish his journey to vanquish the evil Baramos, the king has been waiting for the hero to come of age so that they can take up his quest.

* In ''VideoGame/ZeldaIITheAdventureOfLink'', on Link's 16th birthday a strange mark appeared on his left hand, the Triforce, and thus the adventure begins!
** Recent interviews mention that the Link from ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' actually started his quest at age nine [[FlipFlopOfGod rather than twelve as suggested by]] ''[[VideoGame/TheLegendOfZeldaTheWindWaker The Wind Waker]]'' - which means that Link got to wake up on his sixteenth birthday to the revelation that he's been in a seven-year coma, Ganondorf has the Triforce of Power [[NiceJobBreakingItHero thanks to his and Zelda's screw up]], and now he has to go fix it.
* Inversion: in ''VideoGame/ClockTower3'', the heroine is sent OffToBoardingSchool on her fifteenth birthday to prevent [[spoiler: her grandfather from using her blood in an ancient ritual which will only work while she is fifteen]].

For worse, they don't remember their past lives, and thus they're utterly lost as to what's going on...]]

* Subverted in ''WesternAnimation/AvatarTheLastAirbender'' and its SequelSeries, ''WesternAnimation/TheLegendOfKorra''. The Avatar is supposed to be located at a young age and then informed when they're sixteen, by which point they'll be ready to handle the responsibility (this is demonstrated with Avatar Roku in a flashback). In both series, the protagonist ends up learning too early and thus has problems reconciling their own life with that of being the Avatar.
** In ''Avatar: The Last Airbender'', Aang was informed of his status at the age of twelve due to the looming Fire Nation war. Not ready to accept such a massive shift in his life and the pressures of war, he ended up running away from the temple, got himself trapped in an iceberg for a century, and then had to deal with a Fire Nation that had been running amok for all that time. Furthermore, Aang has trouble weighing his responsibility to the world at large with his own personal values, which comes to a head in the series finale.
** In ''The Legend of Korra'', Korra has the opposite problem. Korra mastered waterbending, firebending and earthbending by the age of four, whereupon she was taken in by the White Lotus and spent the next thirteen years being raised to be the Avatar. As such, Korra's entire life revolves around her being the Avatar, and a recurring theme in each Book is the villain threatening to take that away from her.
* In the ''WesternAnimation/TeenTitans'' episode "Birthmark", Raven's destiny as [[SatanicArchetype Trigon]]'s daughter is revealed.
