* Franchise/TheDCU:
** ComicBook/{{Hawkman}} started doing this after the Golden Age Hawkman from the 1940s was retconned into being the same character as the currently active Hawkman.
** ComicBook/LexLuthor, dying from radiation poisoning ('cause it turned out kryptonite was just like any other radioactive substance to humans), [[FakingTheDead faked his death]] by plane crash then had his brain transferred to a clone body, introducing himself to the world as his own son. After the reveal (which involves clone degeneration and him levelling Metropolis), he pulls a KarmaHoudini by selling his soul for a cure and then blaming everything on an [[MetaphoricallyTrue insane clone that faked his death and took his place]].
%%** The ''Comicbook/LegendsOfTheDeadEarth'' annuals had a new Superman fighting a Luthor who had done this ''sixty times''.
** In the 2006 ''Mystery in Space'' miniseries, Comicbook/CaptainComet finds himself reborn on Hardcore Station in a 20 year old body, and claims to be the original Captain Comet's nephew. His new irreverent attitude means that even heroes who've worked with him before are fooled ... and preferred his "uncle".

* In ''Comicbook/TheLeagueOfExtraordinaryGentlemen'', Mina Harker and Allan Quatermain drink from the FountainOfYouth, restoring both to their late-20s selves. Mina lives on as herself and is noted to be "remarkably well-preserved," while Allan invokes this trope and poses as "Allan Quatermain Jr."

In the 'Vampires' expansion pack for ''VideoGame/TheSims4'', the city of Forgotten Hollow was founded 400 years ago by a vampire named Vladislaus Straud. In order to hide his vampiric nature, he poses as his own descendant, Vladislaus Straud IV.
