** Not overtly in personality but he's much shadier in his lawyer tactics in Seasons 2 and 3 compared to 1. He mostly cleaned up his Slippin' Jimmy attitude at the start of the series and only relied on cons because he was desperate. After reuniting with his old friend Marco at the end of Season 1, he starts conning because he likes it. Jimmy becomes noticeably colder and more cynical in ''Expenses''. First in the scene in the bar where Kim becomes unnerved at his proposed con with the rude customer, followed by his dismissal of her concerns about what they did to [[spoiler:Chuck]]. Then, when he meets the insurance agent, he uses CrocodileTears while letting slip that Chuck was incapacitated so that the agent will jack up Chuck's premiums and maybe have him investigated. He's also more aggressive and [[OpportunisticBastard opportunistic]] in his usage of Slippin' Jimmy tactics such as screwing over the [[KickTheSonOfABitch obnoxious]] music store owners, the community service supervisor, and [[GrannyClassic Irene Landry]]. As his probation and disbarment stretch on, however, he [[spoiler:becomes more and more like Saul Goodman, and eventually starts using the name for his street dealings, proudly selling untraceable phones to known drug dealers and unloading his residual guilt about Chuck's death onto Howard, leaving the latter a broken wreck.]] Taken even further in Season 5. He is [[spoiler:invited to lunch by Howard, who in good faith expresses remorse for siding with Chuck all these years, attempts to bury the hatchet with Jimmy, and offers him a job at HHM. Jimmy's response is to take offense at the idea of Howard pitying him and secretly smash up Howard's car with a bowling ball later that same night.]] It gets even worse in season 6 [[spoiler:Gene goes deep into self-destructive awfulness in the episode [[Recap/BetterCallSaulS6E11BreakingBad "Breaking Bad"]] after a painful phone call with Kim, remaking himself as Viktor, showing no shame for scamming a cancer victim and dismissing concerns from Jeff and Buddy. Even Saul, famous StoppedCaring mask himself, shows concern for Jesse being treated badly in the same episode.]]

* ''Series/MysteryScienceTheater3000'': After Trace left the show and how RealLifeWritesThePlot, Bill Corbett's portrayal of Crow has him come across as way more [[TheBully crude, unfunny, unpleasant, impatient, aggressive and just of a huge bully to Mike]], even Tom Servo isn't immune to ridiculing's Mike the show's Sci-fi years. Crow does mellow out overtime, but still...

** Whilst Linda was shown to have a dark streak involving guns, she was otherwise characterised as a loyal member of Brittas' team and one of the kinder members. Come Series 6 and 7 and she becomes a SoapboxSadie willing to commit acts such as locking Tim up in a cage, stealing and setting free a shark, and setting free Colin's pet rabbit under his nose to prove a point about keeping animals in captivity.
** Ben, Carole's daughter, goes through this the worst. From Series 1-5, he was characterized as a normal toddler prone to the occasional bratty and TroublingUnchildlikeBehaviour, but otherwise harmless, even saving Brittas from the collapsing leisure centre at the end of Series 4. In Series 6, he's a downright EnfantTerrible, with his scenes involving him either arguing with his mother or outright committing deeds such as holding several girls hostage for party bags, maiming a party entertainer possibly for life with a lawnmower, biting other children, and dangling a teacher out of a window.

* Seth Cohen from ''Series/TheOC'' becomes noticeably more self-absorbed in later episodes. Arguably this helped round out his character a bit more and explain his previously [[CoolLoser inexplicable]] unpopularity. In season four, following [[spoiler:Marissa’s death]], he becomes a lot more tolerable in an effort to support Summer and Ryan.

* ''Series/MadMen'''s Harry Crane started off as one of the nicer guys in the office, compared to his more overtly sexist and meaner co-workers; the worst thing he ever did was an immediately regretted one-night stand that left him sleeping on the couch for a while. However, his promotion to the head of the television department quickly went to his head, and eventually he was cheating on his wife shamelessly and repeatedly, constantly making gross comments, and trying to coerce his way into sex with aspiring actresses. By the end of the series, every other character seemed to loathe him.
