** Wanda Maximoff aka Scarlet Witch is by far the most extreme example of this, though it is ultimately justified and consistent given the TraumaCongaLine she goes through. While Wanda obvious wasn’t a saint when she was introduced in ''Film/AvengersAgeOfUltron'' (being along with her brother a Hydra volunteer who aids Ultron), she still had some moral compass and balked at what Ultron was planning. She pulls a HeelFaceTurn to good and in her [[Film/CaptainAmericaCivilWar next]] [[Film/AvengersInfinityWar three]] [[Film/AvengersEndgame movies]] is presented as NotEvilJustMisunderstood with Vision bringing out the best in her. [[spoiler:By ''Film/DoctorStrangeInTheMultiverseOfMadness'' however she’s a mass murdering FallenHero and DarkMessiah who simply doesn’t give a crap about anything except having her twin sons Billy and Tommy in her life again. In fairness, this JumpingOffTheSlipperySlope was well in making considering she was forced to kill Vision to save the universe but her sacrifice amounted to nothing and she had to say goodbye to him again along with her sons in her [[Series/WandaVision TV series]] — before discovering her sons were alive and well in other universes thanks to the Darkhold (which corrupted her further). Wanda does have a HeelRealization at the very end at least, after seeing Billy and Tommy be terrified of what a monster she’s become.]]

** Loki in ''Film/{{Thor}}'': TragicVillain and WoobieDestroyerOfWorlds. Loki in ''Film/{{The Avengers|2012}}'': [[spoiler:psychopath who enjoys ripping a guy's eye out, and directly or indirectly kills around 200 people (80 people in the first two days -- according to Black Widow, including those who died in and after the explosion caused by the Tesseract, unknown number of S.H.I.E.L.D. agents during the attack on the Helicarrier, plus 74 causalities during the Battle of NY -- according to [[https://i.imgur.com/xX1Ac7R.png General Ross's data]] in ''Film/CaptainAmericaCivilWar'').]]

* When he is first introduced in the ''Franchise/JurassicPark'' series, Dr. Henry Wu, [=InGen=]'s chief geneticist, is a decent if incautious person. The "decent" part is more present in [[Literature/JurassicPark the first novel]] than [[Film/JurassicPark the first film]], the former of which sees him actively helping to repair the damage to which he unwittingly contributed, but he a nice guy in both nonetheless. Come ''Film/JurassicWorld'' more than 20 years later, and Wu has become a much more bitter and cynical person, indifferent to the latest casualties of his new ''[[MixAndMatchCritters Indominus rex]]'' and countering the resulting WhatTheHellHero reprimand from Simon Masrani by contending that everything unique and successful about the park is ultimately thanks to him.
* ''Film/Terminator2JudgmentDay'' does this to Sarah Connor, who went from the naive but sweet girl we saw in the first movie into a hardened gun-tolling woman with no time for bullshit. As soon as she learns that Miles Dyson was the creator of [=SkyNet=], her first instinct is to travel to his house and kill him on the spot with his ''wife and son present'' and then later goes on a rant that sounds a lot like something a [[StrawFeminist so-called feminist]] would say. In a deleted scene, she attempts to destroy the T-800's control chip while he was offline despite the fact that the T-800 was the only thing keeping her and John safe from the much deadlier T-1000. This all, however, comes from the fact that she was greatly traumatized from her experiences in the first movie, how she's carrying the weight and desperation from knowing [[TheEndOfTheWorldAsWeKnowIt what's going to happen]] while [[CassandraTruth nobody believes her]], and when the chips are down and she's staring at Miles up close down the sight of a handgun, [[MyGodWhatHaveIDone she can't pull the trigger and collapses to the floor in a blubbering heap]].

* The provider of the image in the trope's main page is the Once-ler from the 2012 adaptation of ''WesternAnimation/TheLorax'', who undergoes a jarring change in temperament (as part of a FaceHeelTurn in a DescentIntoDarknessSong) when his Thneed business becomes a success, turning from a mostly good-natured guy into a greedy, arrogant CorruptCorporateExecutive, carelessly abusing and exploiting the forest creatures he'd previously befriended.

* ''Film/{{Foolproof}}:'' Rob goes from the PluckyComicRelief of the trio to an aloof, dedicated criminal under Leo's tutelage, sabotaging the others' attempt to get out from under Leo's thumb and then [[spoiler:tries to kill them.]] [[spoiler:Subverted with the reveal that he's still working with Kevin and Sam and is just trying to earn Leo's trust for the BatmanGambit to bring him down.]]

As soon as she learns that Miles Dyson was the creator of [=SkyNet=], her first instinct is to travel to his house and kill him on the spot with his ''wife and son present'' before John stops her, and then later goes on a rant that sounds a lot like something a [[StrawFeminist so-called feminist]] would say.

* Clopin from ''WesternAnimation/TheHunchbackOfNotreDame'' is first introduced as the colorful narrator of the film, and the master of ceremonies at the Feast of Fools, where he was very kind to Quasimodo. However, near the end of the movie, he is now the bitter judge (his hand puppet serving as Quasi's defense) presiding over the Court of Miracles, and is now very mean to not only Quasimodo, but also Phoebus as well, and as a result he wanted the two both sentenced to death for being spies of Frollo (they were actually working against Frollo, not for him). Had Esmeralda not showed up at the Court of Miracles to stop Clopin and tell him that both Quasi and Phoebus are trying to help them, Clopin would have actually killed them both.
** This seems to be more about HiddenDepths than becoming more of a jerk - Clopin's mostly rather genial on the outside, but he's ''also'' secretly the leader of an insurgence desperate to stop a madman's oppression of his people (so he's a bit of a StepfordSmiler). He was likely exercising caution to protect his people and simply acted hastily - though he ''could'' have at least waited for their side before passing immediate judgement, true, it's unlikely he would have believed them without Esmeralda vouching for them, and one must remember that Phoebus was the Captain of the Guard prior to this event (information which had likely not yet reached Clopin), so yeah...

** Harry Osborn. Goes from a mostly nice guy in the first movie to lashing out at Peter in the second movie and acting like a douchebag for most of his scenes. In the third film he gets better via a little EasyAmnesia, but then reverts to full blown RivalTurnedEvil. In the end, he redeems himself, but RedemptionEqualsDeath.
** Mary Jane also becomes increasingly self-centered as the series progresses. She has NoSympathy for [[TheWoobie Peter despite all the problems he has]], refuses to hear his side of the story as to why he missed her play, and then dumps her fiancee at the altar to get with Peter! In the third movie she resents Spider-Man's popularity for saving people's lives and not having the time for her, but this time she at least recognizes this as negative behavior, does feel bad about it and tries to do better....but life doesn't make that easy for her.

* Loki in ''Film/{{Thor}}'': TragicVillain and WoobieDestroyerOfWorlds. Loki in ''Film/{{The Avengers|2012}}'': [[spoiler:psychopath who enjoys ripping a guy's eye out, and directly or indirectly kills around 200 people (80 people in the first two days -- according to Black Widow, including those who died in and after the explosion caused by the Tesseract, unknown number of S.H.I.E.L.D. agents during the attack on the Helicarrier, plus 74 causalities during the Battle of NY -- according to [[https://i.imgur.com/xX1Ac7R.png General Ross's data]] in ''Film/CaptainAmericaCivilWar'').]]

* In ''Film/IronMan2'' Tony Stark allows the fame to get to his head ''again'', and it screws him over worse than his playboy tendencies did in the first film. However, [[spoiler: it's something of a ruse. The power source for his arc reactor is poisoning him, pretty much having months to live/find an alt power source. With Hammer trying to get his tech and all of this, he lashes out yet also does it in a matter so Pepper can run the company and make sure it remains right while goading his friend into taking the prototype armor to become War Machine. He doesn't fully recover after seeing the final message from his dad, getting some much needed faith and hope.]]

* Mushu from ''WesternAnimation/MulanII'' spends most of the movie trying to break up Mulan and Shang. It was all just because the ancestors did the same, threatening to separate him from Mulan and give him back his old job of gong ringer if she was married, and he didn't want that. Thankfully, Mushu's lesson is mostly learned (he still makes the ancestors cater to his whims, but not only did they essentially [[CouldHaveAvoidedThisPlot kick-start the plot]], they ''still'' treat Mushu like dirt even post-redemption, so [[LaserGuidedKarma they kinda had it coming]]).

* In ''Disney/CinderellaIIIATwistInTime'', Lady Tremaine. She was already a jerkass, but now she goes from abusing her stepdaughter to trying to kill her. Inverted with [[spoiler:Anastasia]], who becomes sympathetic and eventually makes a HeelFaceTurn.

* Creator/RogerMoore's Film/JamesBond went from being charming and urbane in ''Film/LiveAndLetDie'' to a ''huge'' asshole in ''Film/TheManWithTheGoldenGun''. [[EnforcedTrope This was mandated by the studio to counteract Roger Moore's "nice guy" image"]], as we see him threatening to break a woman's arm, threatening to blow off a guy's testicles, and later pushing a kid salesman ("''bloody tourist!''") into a rapid stream during a boat chase. Having sex with Anders while Goodnight, ''who he was just about to have sex with'', is hiding in the closet. [[WhyWouldAnyoneTakeHimBack And then she still has sex with Bond at the end!]] Fortunately, Moore went back to his previous portrayal for the rest of his tenure.
