Whenever the original instance of a character in a series gets obscured by later developments of the same character, whether it be a sequel, an adaptation, the casting of a breakout character, even a ReTool of the original. In the most extreme cases the original installment hardly gets recognized by anyone but the most hardcore fans.

Possibly a supertrope of both SequelDisplacement and AdaptationDisplacement. The exact inverse of FirstInstallmentWins.

[[folder:{{Anime}} & {{Manga}}]]
* The ''Manga/YuGiOh'' manga started out as the tale of a teenager whose dark side brings judgment on abusive people with lots of horrific implications. Halfway into the series the card game took over and everything from that point onwards became the tale of people beating each other in a SeriousBusiness card game.
* Anyone remember when Bulma was one of two main characters in DragonBall?

[[folder:Comic Books]]
* CaptainAmerica is almost synonymous with ''Comicbook/TheAvengers'', despite the fact he predates them by twenty-two years and wasn't a part of the team's original roster.
* {{Wolverine}}'s origins as a [[ComicBook/IncredibleHulk Hulk]] villain are hardly ever mentioned anymore, if at all.
* The villainous origins of the ScarletWitch, and {{Hawkeye}} have pretty much been swept under the rug. Likewise, {{Quicksilver}} started as a straight villain, and now he is best known for his HeelFaceRevolvingDoor tendencies.
* Mary Jane Watson is regarded as {{Spider-Man}}'s true love, despite her original role as [[BettyAndVeronica The Veronica]].
** Justified, as the Betty has been dead for 40 years.
* Originally, Franchise/{{Tintin}} [[ThePiratesWhoDontDoAnything did some reporting]], but by the fourth or fifth book, he seemed to have surreptitiously retired to the quiet life of getting swept up in fantastic adventures and foiling the plots of mustachioed movie moguls.

[[folder:Film]]
* Creator/HPLovecraft's famous MadScientist Doctor Herbert West was described in the original pulp serial as blonde-haired and blue-eyed. Ever since the film adaptation of ''ReAnimator'' came out, however, just about every subsequent depiction of West in any other work made his appearance much closer to that of actor Creator/JeffreyCombs.

[[folder:Live Action TV]]
* ''SavedByTheBell''. Nobody remembers Miss Bliss, and nobody cares either.
* Similarly, few people remember that once upon a time, ''Series/TheFactsOfLife'' featured girls named Molly, Nancy, Sue Ann, Laura, and Jennifer in addition to Tootie, Jo, Blair, and Natalie.
* The Fonz from ''HappyDays'' was originally conceived as an intimidating, occasionally violent tough-guy semi-villain and semi-criminal. Cue the {{Flanderization}}.
** LaverneAndShirley were... shall we say... portrayed as "easy" girls when they first appeared on ''HappyDays''. And violent. ''Especially'' Shirley.
** [[MorkAndMindy Mork from Ork]] was originally a villainous alien invader intent on destroying the Earth in his first appearance on ''HappyDays''.

[[folder:Music]]
* Singer Julio Iglesias became a musician after a car crash. Before the accident he was Goalkeeper for the Real Madrid Youth Team.
* Ringo Starr is well known as Music/TheBeatles' drummer. Not many people remember his early fame as Rory Storm and the Hurricanes' Drummer.
** The Beatles' (also known as "The Fab ''Four ''") early incarnation as a FiveManBand.

[[folder:Western Animation]]
* ''USAcres''. On the strips Orson started as a small piglet and grew up with the time learning important lessons along the way. On the animated shorts Orson is a mature Pig and the wisest character, often teaching important lessons to young chicks Booker and Sheldon.
