->"She has a newness," he said. "Everything is for the first time... If I had learned she had been born this very morning, I would only be surprised that she was so old."
-->-- '''Prince Lir''', ''Literature/TheLastUnicorn''[[note]]This is said the first time he sees the unicorn, who was indeed changed into a human woman only the previous night.[[/note]]

* Cubert from ''WesternAnimation/Futurama'' was cloned from one of the Professor's more shapely back growths, and was born as a young boy of around ten.

* Various characters in ''Series/DoctorWho''.
* Luke and Sky Smith from the ''Series/DoctorWho'' spinoff ''Series/TheSarahJaneAdventures''.
* Liam Kincaid, the protagonist of ''Series/EarthFinalConflict'' for seasons 2-3. Born with three parents (one of them an alien) he grows from infant to adult over less than one full episode.
* The classic ''Series/TheOuterLimits1963'' episode "Demon with a Glass Hand" [[PlayingWithATrope plays with]] this trope. Trent, the protagonist, begins the story by musing, "I was born ten days ago. A full grown man, born ten days ago." Actually, [[spoiler:he's a robot from 1000 years in the future built to protect humanity from genocidal invaders.]]

* ''Comicbook/YoungJustice'': ComicBook/{{Superboy}}. His exact age depends on the continuity, but he's generally freshly cloned.

--->[[spoiler:'''The Vision:''']] Well, I was born yesterday.

* The copies of Pinkie Pie from the mirror pool in ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' all have her [[GenkiGirl same]] [[CloudCuckooLander personality]], but none of the knowledge, memories, or life lessons the original has learned throughout the course of her life. The result is a large number of obnoxiously destructive versions of Pinkie Pie (In other words, it's not pretty).

* Madelyne Pryor, Scott Summer's first wife in ''ComicBook/{{X-Men}}'' was eventually {{retcon}}ned into a clone of Jean, but despite this she's pretty well socially adjusted until she goes nuts after Scott abandons her.

* ''Literature/TheLastUnicorn'': Lady Amalthea is immediately noticeable as having a "newness" to her, where each movement she makes indicates that she's doing many things for the first time. This happens to be because [[spoiler:up until that point, she was a unicorn]].

* ''Comicbook/YoungJustice'': Superboy. His exact age depends on the continuity, but he's generally freshly cloned.

* Manga/MahouSenseiNegima: It's noted at several points that despite being a middle-schooler, [[RobotGirl Chachamaru]] is technically only two years old.

* In ''{{Trigun}}'' at least two of the characters are like this.

* In ''{{VideoGame/Overwatch}}'', Orisa stands out as the exception to the robot rule mentioned about because her stated age is 1 month old, having been created by the (pre)teen genius Efi Oladele from the remains of an OR-15 robot that was destroyed in an attack by Doomfist. The developers specifically bring this up as something that makes her stand out from other heroes in the 'verse, some of whom have histories going back decades, and cited by her creator as why she's still getting the hang of this whole "hero" business. For comparison the other Omnic who's a playable character, Zenyatta, is 20 years old and is portrayed as a wise mentor figure, even to characters who are older than he is.

* Grunt from ''VideoGame/MassEffect2'' is a [[DesignerBabies Designer Baby]] SuperSoldier and the only one of thousands that his Krogan creator Okeer thought was worthy, and he's basically born in your cargo bay when you release him from his tank. He does come with some NeuralImplanting, but you're the first person he actually talks to outside of Okeer talking to him while he was in his tank (when he was unable to respond).

* In ''Anime/KemonoFriends'', the titular Friends are all LittleBitBeastly girls born from a live animal or biological samples of them coming into contact with [[{{Phlebotinum}} Sandstar]], and most of them are probably much younger than their appearances would suggest. The best example is definitely [[spoiler:Kaban/Bag, the TokenHuman, who is at most a few days old by the end of the series since she was born during the last Sandstar eruption after a bit of it came into contact with a human hair inside a lost hat]].

* In ''{{VideoGame/Overwatch}}'', Orisa stands out as the exception to the robot rule mentioned about because her stated age is 1 month old, having been created by the (pre)teen genius Efi Oladele from the remains of an OR-15 robot that was destroyed in an attack by Doomfist.

* ''{{WesternAnimation/Young Justice}}'': Superboy. Not quite "yesterday" but he's [[ArcNumber 16 weeks old]] in the first episode.
* ''WesternAnimation/Ben10UltimateAlien'': Eunice is a 16-year old girl [[NakedOnArrival is found on a spaceship]], later in the episode is discovered to be a Unitrix splicing Gwen's DNA.

* Belphoebe in the ''WhateleyUniverse'' is a cloned drow created by one student (Belphegor) using the cloning chamber he'd stolen from another (Jobe Wilkins) and accidentally imprinted with a copy of his own memories. Hence while chronologically she's 0, she looks 16 and is considered that age by the administration, staff and students.

* In ''{{VideoGame/Overwatch}}'', Orisa stands out as the exception to the robot rule mentioned about because her stated age is 1 month old, having been created by the (pre)teen genius Efi Odelawe from the remains of an OR-15 robot that was destroyed in an attack by Doomfist. The developers specifically bring this up as something that makes her stand out from other heroes in the 'verse, some of whom have histories going back decades, and cited by her creator as why she's still getting the hang of this whole "hero" business.

* The ''Fanfic/AnAstralDropInHeatherfield'' starts with Hope's literal moment of creation and ends only two months later - although she packs a lot into her first few weeks alive.

* The Pheonix in Kanye West's Runaway

* ''WesternAnimation/StevenUniverse'': Concept art for "Hit The Diamond" implies that one member of the [[AdorableEvilMinions The Ruby Squad]] sent to Earth, the one with the gem in her leg, was literally created one day before their mission, which explains her NaiveNewcomer personality and general lack of self-confidence.
