** Dan Humphrey is the prime example from ''GossipGirl''. He started out as the show's moral compass who always believed in doing the right thing. Flash forward to season three where he's dating his lifelong best friend Vanessa but cheats on her with Serena (who, at the time, was dating Dan's only male friend Nate) and doesn't seem to think he's done anything wrong. When Vanessa for some reason wants to get back together in season four he begins to sleep with her and lets her think they're back together, leaving her to take care of the son he has by Georgina Sparks while he runs after Serena. By season five he has fallen in love with Blair and could care less that she drove his sister Jenny out of town. He then publicly humiliates Blair at her wedding by sending in a video to Gossip Girl which he blames first Chuck and then Serena for. He then tells a newlywed Blair that unless she begins to date him (Dan) he will no longer be her friend. They do date for a while but then he cheats on her with Serena. When he finds out Blair is leaving him for Chuck he makes good on his promise to not be her friend unless he can be her ''boy''friend and sets out to write a book that will uncover all her secrets (and the secrets of the rest of the NJBC) because he feels wronged. So much for moral compass...
* Kengo from ''KamenRiderKiva'' disappears after a couple of tragic events, then returns several episodes later [[TookALevelInBadass with special training]] and a chip on his shoulder, especially regarding Wataru and Nago. Thankfully, [[UnexplainedRecovery he gets better]].
* Dr. Eric Foreman on ''Series/{{House}}'', who started off as a fairly self-possessed guy who didn't really appreciate House's shenanigans, and then progressed to the type of guy who screwed over a colleague and then stabbed her with a dirty needle (the latter under duress, but still). His jerkassery has calmed somewhat, but hasn't completely gone away. To be fair, the growing jerkassery did become a plotpoint after that -- Foreman was afraid that spending so much time around House was causing him to become more like him. He quit Princeton-Plainsboro to try to stop this... but then got fired from a job in New York after using very House-like tactics. Cuddy even once called him "House-Lite."

* Detective Quinn in season six of ''{{Series/Dexter}}''. He had already stolen from a crime scene earlier in the show, but he got worse. After screwing up at work he shows up to his ex-girlfriend/new boss Debra's housewarming party drunk off his ass with a girl he picked up from a bar, and proceeds to act like a douche to all present. It's quite telling that [[EveryoneHasStandards even the girl leaves]] because he took her to his ex's party simply as a cheap insult, and his partner (Batista) straight-up slugs him when he takes it too far by harassing his sister. In the following episodes he goes out drinking on week nights, behaves like an obnoxious asshole at strip clubs, doesn't show up for work, gets his partner almost killed by getting drunk and sleeping in instead of going to work. When he's fired for it, he manages to stay by exploiting a loophole intended for helping alcoholics. (He is an alcoholic, but only because he's such a Jerkass, not because he actually needs help)
* Mike Stivic of ''Series/AllInTheFamily'' apparently turned into a jerkass after he, Gloria and Jr. moved to California. We never see exactly how it happened, but he started to ignore his once beloved wife and son, slept around with another woman, compared marriage to Hell and he [[ArsonMurderAndJaywalking called Gloria fat.]]

* Similar to the above is the story of Justin Russo of ''Series/WizardsOfWaverlyPlace''. Justin was originally just a lovable nerd whose [[InsufferableGenius over-achieving sometimes got the better of him]], and later on a [[TookALevelInBadass badass]] who would fight to the death for his loved ones. Following the "Wizards vs. Werewolves" special, Justin became his sister Alex's bitter arch-rival.
* On ''Series/EverybodyLovesRaymond'', Debra started out in the early seasons as a fairly reasonable everywoman who seemed to have a quite playful and loving relationship with Ray. Then, the character suddenly changed. It's hard to pinpoint exactly ''when'' the change occurred, but Debra eventually became a raging, [[DoubleStandardAbuseFemaleOnMale physically-abusive]] and {{smug|Snake}} KarmaHoudini who treated Ray like trash, [[DomesticAbuse beat him up]], forbade him from seeing his friends most of the time, and convinced Ray's own children to feel contempt for him. Oh, and the worst part? The show tried to act like ''she'' was the reasonable one, despite her abusive, {{Jerkass}} behavior. So basically, she went from being a well-rounded, likable character in the beginning to the writers' MarySue by the end.
*  Series/{{Buffy|TheVampireSlayer}} had become increasingly arrogant over the last two seasons. It's partially justified in that being yanked out of Heaven and coming to BuriedAlive in her own grave had been very traumatic. However, by the last season she had practically declared herself dictator of the group and made sneering comments when one of the girls under her charge committed suicide.

** {{Inverted|Trope}} on the ''Time Bandit'', where the other crew started treating Mike Fourtner badly when he was actually given a test run in the Captain's chair.
* Jack Hunter on ''Series/BoyMeetsWorld'' in season 7. He started out basically a Nice Guy who was a little naive due to being new in town and occasionally exasperated with Eric's Cloud Cuckoo Landerness. In the season 5 premiere episode "Brothers," we are introduced to him as someone raised by an upper-class stepfather. His estranged brother Shawn assumes he's a rich brat because of this. However, in the following episode "Boy Meets Real World," while he and Shawn are arguing, Jack admits to working summer jobs in order to obtain the money he has, thus giving Shawn and the viewers a positive impression of him. But he seemed to transform into a Jerk Ass after his breakup with Rachel in the season 7 premiere episode "Show Me the Love." Throughout season 7, he degrades into a narcissistic, spoiled pretty-boy. This is especially lampshaded in the ante-penultimate episode "Angela's Ashes," when Jack is cut off from his father's funding. Rachel tells him he can't go to fancy restaurants, shop at name-brand stores, get expensive haircuts, and such. Jack whines throughout the episode about this, even as he's [[spoiler: saying goodbye to Angela who's leaving for Europe for a year with her Dad.]]
* In Season 5 of ''Series/{{Chuck}}'', Morgan, the title character's friend, turned into quite a self-entitled asshole, brushing off Chuck and the rest of his team, and even going as far as joining a rival spy firm. [[spoiler: However, Morgan himself isn't at fault for it, as the Intersect that he gained at the end of last season was "tainted", causing him to lose himself, so to speak. He eventually had it removed after four episodes or so.]]
* Walter White of ''Series/BreakingBad'' becomes less and less sympathetic as the show goes on. [[WordOfGod Vince Gilligan]] has confirmed this is deliberate.
* ''{{Series/Roseanne}}'''s titular character started out as a gruff, but otherwise friendly and wisecracking blue-collar woman who loved her husband and kids, and slowly transformed into a cruel, selfish, sniping, raging, shrieking bitch with severe misandrist tendencies. On top of that, she was often portrayed as being in the right and getting away with being an asshole to everyone. Her daughter, Darlene, seemed to follow her into this mold. Given that this dovetailed with the men of the show (particularly Leon, Mark and David) becoming more and more pathetic, useless, and stupid, and that the show was practically written and run by Roseanne herself, it's a pretty clarifying look into her mindset at the time.
* Pierce and Abed respectively went through this in the second and third seasons of ''Series/{{Community}}''. Pierce started out as a fairly harmless CloudCuckooLander who eventually, after feeling his friends will leave him eventually, turns into a total JerkAss who goes so far as to try and egg on a suicidal student. Abed wound up embracing his dark side over the course of the third season which saw him regularly insult his friends and often do whatever he wanted regardless of any of their feelings. However, while Pierce does become a bigger jerk, he also became more sympathetic and developed a FreudianExcuse, making him an odd combination of this and TookALevelInKindness.
