History AgeLift / FanWorks

* This is the main idea behind the ''Webcomic/Persona5AdultConfidantAU'', where all of the [[VideoGame/Persona5 original game]]'s child and teenage characters are now adults and the adult characters are now teenagers, with the once adult confidant characters now acting as the teenage Phantom Thieves.

* ''Fanfic/TheYoungStag'' has several characters aged up or aged down for the purpose of the story. Arya Stark, for example, is introduced as 14, mainly because of her PerfectlyArrangedMarriage to Steffon, who is 15 at the start of the story.

* ''[[https://www.fanfiction.net/s/13238312/1/The-Last-Prayer The Last Prayer]]'' goes both ways. Naruto's peers are all three years older, making them sixteen to seventeen (twenty in Temari's case). On the flip side, Mabui and Samui are twenty instead of twenty-six and Kurenai is twenty-four rather than twenty-eight. Similarly, Mei Terumi is approximately a decade younger than canon, being in her mid-twenties rather than mid-thirties.

* ''FanFic/ToHellAndBackArrowverse'': The writer made a minor adjustment to the ages of the main protagonists; Oliver is now only two years older than Barry, who is two years older than Kara. The biggest change is Kal-El, who is several decades younger than he is in canon due to being in the same ship as Kara and thus stuck in the Phantom Zone with her.

[[AC: ''Franchise/DCComics'']]

* ''Manga/{{Evangelion 303}}'': Shinji, Asuka, Rei, Kaworu, and Mari are 18 or older as opposed to 14. This also affects their characterization too, and is how the story differentiates from its source material. They drink, drive, have sex lives (or develop one), and are generally more worldly and independent than their teen counterparts.

* In ''Fanfic/TheLastSon'', Clark Kent begins his career as a superhero at age 19, while modern depictions of Superman have him do so at his late twenties to early thirties.

* ''Fanfic/BoopTheSnootForCriticalDamage'': All the main characters from RWBY are given a slight age increase.

* In ''Fanfic/YinYang'', Evil-Lyn is a child when Keldor attempts his coup and becomes Skeletor, which makes her much younger than she was in the 2002 series, where she was an adult at the time.

* In ''[[https://www.fanfiction.net/s/12643461/1/Caged-Wings Caged Wings]],'' Dawn, May, and Ash (originally 10 years old) are aged up into teenagers to fit the setting, a HighSchoolAU. Nando also becomes a teenager, but he's aged down instead of up, since he was originally a young adult of VagueAge.

* In ''[[https://www.fanfiction.net/s/12643461/1/Caged-Wings Caged Wings]],'' Dawn, May, and Ash (originally 10 years old) are aged up into teenagers [[HighSchoolAU to fit the setting.]] Nando also becomes a teenager, but he's aged down instead of up, since he was originally in his 20s.

* In ''Fanfic/ReverseRWBY'', the ages of characters are shifted around. For example, Watts is a teenager, while Whitley is an adult (and is older than his sisters).

* Both Sonic and Elise are eighteen in ''Blog/{{Solarhood}}''.

* ''[[https://www.fanfiction.net/s/13470641/1/Ara-Ara Ara Ara]]'' goes both ways. U.A. is changed to a university so all the students are three years older. On the other hand, Moe [[RelatedInTheAdaptation Bakugou]] aka Burnin' is a third year student, making her five years younger than canon.

[[AC: {{Crossover}}]]
* ''Fanfic/ChildOfTheStorm'' and its sequels broadly keep the generations the same (i.e. those people who are contemporaries in canon broadly remain contemporaries), but play around with character's ages relative to main character Harry Potter/Thorson, who's 13 and a half when the story starts - for instance, Carol Danvers, eventual {{Deuteragonist}}, who first appears in the comics in her late 20s, makes her first appearance as a 15 year old. By contrast Wanda Maximoff, a.k.a. the Scarlet Witch, is Harry's godmother and thus is in her mid 40s (though thanks to the age slowing effects of practising magic, [[OlderThanTheyLook she looks about 30).]]

* ''Fanfic/HarbingerFinmonster'' (''WesternAnimation/DannyPhantom'', ''WesternAnimation/ParaNorman''): Gideon is in high school in this world, being roughly as old as Wendy.

* ''Fanfic/RubyAndNora'': Ruby is a few years older than in canon]], and as a result, so are almost the entire cast.
