* Jack from ''Webcomic/GunnerkriggCourt'' (pictured on the main page). He started off as a pretty normal guy, then he briefly got pulled into a DarkWorld and saw some ''very'' unpleasant things, [[GoMadFromTheRevelation causing him to become insane]]. Since then he became increasingly antisocial, paranoid (at one point he starves himself because he's convinced the Court has laced his food with nanobots to track him) and amoral (compare his treatment of the Laser Cows to his treatment of the Guard Robot). [[https://static.tvtropes.org/pmwiki/pub/images/Jack_Progress_7447.jpg Not to mention, even his appearance became worse over time]]. Fortunately, after [[spoiler:Zimmy removed the whitelegs from his head,]] he's gotten almost back to normal. Oh, and [[spoiler:[[TheCuckoolanderWasRight he was right]] [[ProperlyParanoid about the food]]]].

* ''Webcomic/SweetHome'':

** Anadyne's despair at failing to save Stockyard, and accidentally decapitating him when she tried to rescue him is exacerbated by the First Silver. She lies despondent in the belly of the Silver Eel, until it merges with her and she ''tears of her own breast and shoves it in Stockyard's decaying head'', then walks into the night having become an avatar of pain and suffering and the face of a magical weapon of mass destruction.
** Duane becomes more and more desperately obstinate about his brother being righteous as he's faced with evidence Lemuel was a war criminal who likely betrayed him to the Black Tongue who arranged his death and zombification. In his vehement denial he starts acting less and less logically and lets Aldish soldier into a shrine thinking they won't harm any children despite know soldiers are not always noble. This results in the deaths of several named characters and in the main cast being fractured.

* ''Webcomic/TheCroaking'': Del, after failing to kill his classmate Scra, failing to get his father's approval or sympathy, can't look in the mirror for fear of seeing the reflection of his father and starts to murmur [[MadnessMantra "sickening, sickening"]] whenever he sees Scra, or anything that reminds him of his [[FantasticRacism least favorite classmate]]. After getting kicked of the Aerial Combat team, his sanity degrades further: he starts living in a canyon and crafts a knife of stone to finally murder Scra ... [[spoiler:only to get killed in turn]].

** Lemuel, in Duane's memories of their time in the army, was effected poorly by the horrors of war and feeling abandoned by his family. Despite being an amazing warrior Lem took more and more actions that were petty revenge and needless destruction, culminating, at least from what Duane knew about, in burning a cart full of unarmed restrained prisoners. He did get quite good at hiding his war crimes from authority figures though.

** By the time the comic starts Roger has spent fifteen years having his memories and soul dissolved so Crescian wrights can pick through it to figure out how to dismantle the Dammakhert. He is far from the princely noble rebel leader he was when Duane and Lemuel ran into him during the Foi-Hellick rebellion.

* ''Webcomic/{{Unsounded}}'': Lemuel, in Duane's memories of their time in the army, was effected poorly by the horrors of war and feeling abandoned by his family. Despite being an amazing warrior Lem took more and more actions that were petty revenge and needless destruction, culminating, at least from what Duane knew about, in burning a cart full of unarmed restrained prisoners. He did get quite good at hiding his war crimes from authority figures though.

* ''Webcomic/{{Homestuck}}''--
** Karkat starts getting shades of this after a particularly brutal TraumaCongaLine. [[spoiler: Two of his friends were murdered in front of his eyes, two others are on killing sprees, he's dragging his newly-blinded friend's body (and accidentally drops him down some [[RunningGag stairs]], and he gets a message from his girlfriend, pronouncing the details of another murder - and when he tries to contact her, one of the AxCrazy trolls responds, hinting that she's been killed.]]

** Hyein goes more and more crazy as time goes on, from a confident if a little bossy woman to a raving lunatic who tries to burn someone else alive in their sleep with a Slasher Smile. [[spoiler: After almost being raped by Gapsu and then believing that she'd killed an innocent woman, she completely loses any remnant of sanity she had left.]]
** Ihyun starts as an Affably Evil follower of Joon who, despite his loyalties, seems nice enough. [[spoiler: Then he kills the Tentacle Monster and makes it clear he may be the most insane one out of all of them.]]

* Bryce of ''Webcomic/WeAreTheWyrecats'' is falling victim to this due to a tumor in his brain.

* Vaarsuvius spent most of "Don't Split The Party" undergoing this in ''Webcomic/TheOrderOfTheStick''. [[spoiler: They ultimately recovered but not before committing an act which may have completely crossed the MoralEventHorizon.]]
* Jin of ''Webcomic/WapsiSquare'' suffers from a bad case of this after [[spoiler:destroying the calendar machine. It was actually built at least partially for the purpose of keeping her sane]].

* ''Webcomic/GarfieldMinusGarfield'': With no cat to give him sarcastic remarks, Jon Arbuckle slowly descends into madness. Examples include [[http://garfieldminusgarfield.net/post/27473059 smushing ice cream cones into his face]], [[http://garfieldminusgarfield.net/post/40406640 dressing up for a date... that's in three weeks]], ''[[http://garfieldminusgarfield.net/post/78032638 jumping in the streets wearing a party hat]]'', [[http://garfieldminusgarfield.net/post/81381173 chasing cars in the manner of dogs]], [[http://garfieldminusgarfield.net/post/503880743/try-g-g-in-book-form breaking]] [[http://garfieldminusgarfield.net/post/26654167 down]] sobbing at the most random times, [[http://garfieldminusgarfield.net/post/30759171 Madness Speak]], and, finally, [[http://garfieldminusgarfield.net/post/69159474 being sent to a Mental Hospital]].
* ''Webcomic/BittersweetCandyBowl'' has Lucy having a mental breakdown when Michael falls off a rock bridge while saving her.
* In ''Webcomic/{{Pacificators}}'', one of the best Pacificators they had, [[DisproportionateRetribution Castella]] [[HeWhoFightsMonsters Brandsford]], snapped and [[NightmareFuel murdered thousands of people]] before she was killed by a suicidal guy. Ever since, the regular people have hated the people who has [[ElementalPowers powers]], because they [[TearJerker fear another Castella Brandsford]].

* In ''Webcomic/DistortionNuzlocke'', Johnny goes through this more and more as the story goes on. He was already pretty messed up, but his fantasies cause him even more pain.
* Tekno slips in ''Webcomic/SonicTheComicOnline'' after her and Shortfuse become trapped in a dimension without modern technology. Tekno being a TeenGenius takes this very poorly and becomes more disheveled by the day. It comes to the point where she's writing manically on the walls and [[spoiler:she attempts to murder a villain by beating him to death]].
* In ''Webcomic/GirlGenius'', Gil's father [[spoiler:overlaying his own personality over a portion of Gil's mind]] and his [[spoiler:inheriting the responsibility of ruling his father's quickly crumbling empire]], combined with losing nearly every single friend and family member he had all at once, has not been kind to him and he's implied to have been in TheMadnessPlace for ''two and a half years''. All of Europe can tell there's something off with him.
* Bryce of ''Webcomic/WeAreTheWyrecats'' is falling victim to this due to a tumor in his brain.

* Rocky in ''Webcomic/{{Lackadaisy}}'' was never exactly ''stable'', what with his habit of turning into an AxCrazy PyroManiac when under severe stress, but suffering a severe head injury from a car definitely didn't help matters.
* ''Webcomic/JackTheAmericanGhost'': While she wasn't that sane to begin with, Cindy definitely goes off the deep end by the end of the series, due to her being a LoonyFan for Jack while watching his growing relationship with Go-Eun.
