* ''WesternAnimation/MonsterFamily2'': Mila Starr, the daughter of scientists Maddox and Marlene, spends most of the movie hunting and capturing monsters for her parents experiments, trying to be the perfect daughter. But upon completing her mission, she is told to her face that she is not the Starr's daughter but just an orphan they adopted, and the monsters she captured for them where to help give life to a new, perfect robotic copy of Mila meant to replace her.

* In many versions of Myth/ArthurianLegend, King Arthur grows up believing he's the son of a minor knight named Ector. He only finds out from Ector that he is in fact the HiddenBackupPrince whom Ector fostered (upon orders from the wizard Merlin) only after he draws the sword from the stone and is due to become king. He's genuinely aggrieved by this since Ector and his wife were GoodParents to him.

* ''Series/LegendOfTheSeeker'': After Ren asks how his father could sell him to the D'Harans, this is the response he gets. It seems he only married Ren's mother (though were not told why-perhaps he was promised a high dowry as a bribe to cover up her extramarital pregnancy).

A sub-trope of DeceptiveLegacy. Don't confuse with IHaveNoSon or ThatThingIsNotMyChild, which is where the child ''is'' related to the parent, but the parent has disowned them. Also, this is not simply a subversion of LukeIAmYourFather; this trope only applies if the non-father was actually believed to be the father. Compare and contrast with YoureNotMyFather.

TheReveal that his parents are not his biological parents after years of ObliviousAdoption. This is when after a long time, the adoptive parents finally tell him.

Nothing to do with IAmNotMyFather.

* ''[[VideoGame/PrincessMaker Princess Maker 4]]'': Going through [[GuideDangIt the correct events]] will result in Patricia learning that [[spoiler:the Demon Lord]] is her biological father and rushes home, gripping her [[PlayerCharacter father]]'s arms and begging him to tell her that it's not true. Shortly after that scene, though, it makes no difference to Patricia because she still loves her father.

TheReveal that his parents are not his real parents after years of ObliviousAdoption. This is when after a long time, the adoptive parents finally tell him.

* ''WesternAnimation/BuzzLightyearOfStarCommand'' spoofed its own [[WesternAnimation/ToyStory2 source material'' this way by having Zurg claim he's Buzz Lightyear's father to distract him long enough to knock him out. Then, once Buzz awakens, Zurg tells him he was just toying with him.

-->'''Young!Peter:''' Happy Father's Day Dad.\\

** The trope was subverted in the original, however. Mr. Ping tells Po the secret ingredient to his soup instead.

* In Disney's ''Disney/{{Hercules}}'', after Hercules ends up smashing up a lot of stuff in town because he can't control his strength, his mortal father decides to tell him that he's adopted and gives him the medallion with the symbol of Zeus on it, which leads him to the temple.

* In ''Film/{{Thor}}'', Loki becomes suspicious after a touch from a Frost Giant doesn't burn his skin but colours it temporarily blue. He confronts Odin, who tells Loki that he was found by him in the aftermath of the great battle against the Frost Giants as an abandoned infant and that Odin [[InterspeciesAdoption took Loki]] hoping that he could bring peace between Asgard and Jotunheim through him. [[GoMadFromTheRevelation Loki doesn't take this well]].

* ''Fanfic/TheLoveClub'': Before dying, Frexspar tells Elphaba a secret that he's held for over twenty years: she isn't his biological father.
