Dangerous Sixteenth Birthday

aka: Dangerous Eighteenth Birthday
There may be no more unfortunate age to turn than sixteen, especially if you're female, although in all media 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 manifestation of powers, possibly some ancient conspiracy or prophecy, and the end of a "normal" life for the character in question. Growing Up Sucks.

There are some Real World reasons why 16 is often chosen as The Age At Which 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 (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). 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 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 Harry Potter 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.

Often overlaps with The Hero's Birthday as the precise moment at which everything hits the fan.

  • In the Percy Jackson and the Olympians series, there is a prophecy known to apply to whichever child of the three major gods next reaches their sixteenth birthday. 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 will never age and thus will not turn sixteen. After, 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, 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.

  • Subverted in Avatar: The Last Airbender and its Sequel Series, The Legend of Korra. 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.

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 figured out how to bend three different elements at the age of four, whereupon she was taken in by the White Lotus and spent the next twelve years being raised to be the Avatar. As such, Korra's entire life revolves around being the Avatar, and a recurring theme in each Book is the villain threatening to take that away from her.
  • Teen Titans: Raven has a dangerous unnamed birthday when she was destined to become her demon father Trigon's portal to Earth. In fact the comics the show was based on had entire groups of Titans gaining powers/powerups at sixteen.
