The character's financial position is different from what it was in the source material. The list of possible reasons for this is practically endless. Maybe the creator wants to do an Adaptational Angst Upgrade by making the character either The Tramp or Lonely Rich Kid. Maybe the creator needs the enhance the love triangle by turning it into a Rich Suitor, Poor Suitor situation. Maybe the creator likes Costume Porn, and what better way to insert some than have the character wear fur and gems? Or it can be the result of Flanderization, when a character slightly richer or slightly poorer than the rest becomes unbelievably rich or horrifyingly poor over the course of a franchise.
Whatever the reason, the character gets noticeably richer or poorer than in the original.
When done badly, it can lead to Adaptation-Induced Plot Hole or inconsistencies in characterization (such as: it's stated that the heroes who are altruistic and helpful, according to canon, suddenly have enough money to feed a small country, but for some reason they only use it to buy jewels and cars for themselves).
Note that a character getting or losing a title in the adaptation isn't necessarily this trope (even if it's a lowborn girl becoming a princess). The different financial standing must be obviously shown or stated.
- Downplayed in Magical Girl Lyrical Nanoha A's. In the main continuity, Hayate is financially supported by a friend of her late father. In the movie adaptation, she's simply living off the money from her parents' estate since the subplot involving Graham's plans to sacrifice her to seal the Book of Darkness was Adapted Out.
- Batman. As Movie Bob put it...
In the early Batman comics, Bruce Wayne was only pretty damn rich. Old money, didn't have a day job, you get the idea. But by now, he's so wrapped up in the daily affairs of the DC Universe that he routinely hangs out with aliens and gods, fighting apocalyptic wars, monitoring the globe with satellites, building space stations and paying for most of it himself because he's freakin' Scrooge McDuck levels of rich.
- In The Lord of the Winds, the heroine's family is incredibly poor. In the 1984 stop-motion adaptation, they are quite comfortably off. Justified, since in the original story, the heroine and her sisters went to the eponymous lord of the winds to offer themselves as potential brides in exchange for him stopping a deadly snowstorm, but (probably due to the obvious Unfortunate Implications) the romance was removed in the adaptation, so instead the heroine's sister gets sent to appease the lord of the winds with rich gifts.
- A Fandom-Specific Plot in the Harry Potter fandom involves Harry and/or Hermione (but rarely the Weasleys) turning out to be amazingly rich (yes, in Harry's case, even richer than he actually is in canon). It is so well-known it regularly gets spoofed in fanfics such as The Coolest Evil Dumbledore Ever, where Harry becomes the richest wizard in the world, with more than one hundred million Galleons inherited from his Potter ancestors alone, and the owner of many castles, four houses and a two-room flat.
- In Heroic Myth, Gilgamesh is one of the first Servants Bell summons. As a result, the Hestia Familia instantly goes from living in a rundown church to getting their own mansion. Gilgamesh's endless wealth leads to Conspicuous Consumption, as he buys things like Undine Cloth swimsuits for the Familia that would easily cost hundreds of thousands of Valis on a whim.
- In The Many Sons Of Winter, the entire North is much, much more prosperous than in canon, thanks to its economy being based on a Westerosi version of highland cattle.
- The Professional Wrestling series The JWL made Khosrow Daivari into a "The Million-Dollar Man" Ted DiBiase Expy with contacts all over the world. His business in Myanmar led to that country's dictator Than Shwe giving Daivari his first charge, a masked Wrestling Monster named The Burmese Python. This is completely different from how he was portrayed in WWE, where he was the Angry Persian-American Man manager of Muhammad Hassan.
- In Roadside Assistance, Neptune's family, the Vasilias', own half of the nuclear plants on the planet. They're on par with the Schnee's in terms of wealth. As a result, Neptune and Weiss have known each other their entire lives. The two end up partnering up and married in something just shy of a monopoly, making them billionaires.
- In now that i can see your face (i can stand up to anything.), Shaggy isn't Secretly Wealthy. His mother runs a small diner.
- In Heroic Myth, the Hestia Familia goes from Rags to Riches practically overnight thanks to having Gilgamesh among its ranks. While the Hestia Familia was fairly well-off after their War Game with the Apollo Familia, here the only one they're in debt to is Gilgamesh himself due to him bartering his treasure for ludicrous amounts of cash.
- Downplayed in the 1983 Soviet adaptation of Mary Poppins, the second part of which (roughly corresponding to Mary Poppins Comes Back) adds the subplot of the Banks family being in heavy debt after a fire and Miss Andrew, of all people, being prosperous (the fact that she promises fifteen thousand pounds to a child she would like is the chief reason Mr. Banks, desperate as he is, agrees to let her care for Michael and Jane, even with the unrealistic nature of the promise).
- In the 1981 Soviet adaptation of The Woman in White, Walter Hartright (fairly successful and well-known in the novel) is hard up in the beginning, and the position at Limmeridge comes as practically a salvation.
- In Cloak & Dagger (2018), Tandy comes from an impoverished, single-parent household, while Ty comes from an upper-middle class family. In the original comics, Tandy is the daughter of a successful model from Shaker Heights, while Ty is a homeless runaway from a poor family in Boston.
- In the Archie Comics the Jones family is normally portrayed as being in the same reasonably comfortable standing as most of the other characters families. In Riverdale, it's is a major plot point that the Jones are quite poor, living on the Southside of town in a trailer park.
- Downplayed, with the Lodge family. In the comics the Lodges are often portrayed as insanely wealthy to the point of being one of the richest families in the world. With the series attempts at higher realism, this is grounded into them being only incredibly rich.
- Downplayed with the Andrews. Whilst mostly fine, also following the series attempts at realism, as a working-class family they occasionally face financial issues. A minor plot point in season one is that Andrews Construction is struggling, and delays with building could sink the company. Overall such issues aren't usually a problem in the comics.
- In The Dresden Files TV series, Harry is significantly more financially secure than in the novels - he owns an old but very nice home outright, whereas in many of the books he was often struggling to make rent in a tiny cellar apartment. In the show, Harry's secretly-evil adoptive father, Justin Morningway, was considerably more well-off and Harry ended up the sole inheritor of his estate. Harry wanted nothing to do with it except to help secure a new home far away, though. An old fan joke was that the show was the result of Harry (of the novels) selling his life story to help make rent.
- In Game of Thrones Tywin reveals that the gold mines of Casterly Rock ran dry, putting the Lannisters in serious financial trouble that they have to work around for the rest of the series. No such thing happens in the books.
- In The Queen of Spades by Alexander Pushkin, Liza is the Countess's penniless and insignificant distant relation who doesn't even get anything like pocket money. In the opera by Pyotr Ilyich Tchaikovsky, she is the Countess's granddaughter and heiress, engaged to marry a prince. It is extremely plot-relevant, since in the opera, Herman really does fall in love with her, and hadn't she been beyond his reach, there would have been no barrier to their relationship.
- In Friendship Is Magic, the Apples are actually quite wealthy in this incarnation due to their apple business apparently taking off. When Twilight comes to Applejack's house to talk to her, she's shocked that she and her family live in a mansion.
- DuckTales (2017) has Doofus gotten a huge inheritance from his grandmother. It changed him a lot from being a friend of Launchpad in the original show to a very spoiled creep who treats his parents as slaves.
- Archie Comics launched She's Josie in 1963, in which the canon couple, Josie McCoy / James Depending on the Writer and Alan Mayberry are targeted by Shipping Torpedo Spoiled Brats Alexander and Alexandra Cabot. The Cabots are as stupendously wealthy as the Lodges. However, in the Animated Adaptation Josie and the Pussycats by Hanna-Barbera, the Cabot twins seem to be scraping by along with the Pussycats. Only a throwaway line by Alexandra to the manager of a wrecked department store to "put it on Daddy's account" gives any clue that Cabots have resources. It was felt that having wealthy teens buy their way out of scrapes would be detrimental to plot development, so the Cabot twins were kept on a tight financial leash. Archie Comics would later Retcon this as Mister Cabot getting his "worthless progeny" out of his hair by having them manage an all-girl garage band on a global whirlwind tour.
