Over the course of a story an insane character actually becomes less insane and more sane as time passes. The opposite of SanitySlippage. They may start out sane and become insane before becoming sane again. The point of the trope is that they ultimately end up as more or less sane or saner.


[[folder: Anime and Manga ]]

* Harry in ''Anime/OutlawStar''. He starts off as an AxCrazy StalkerWithACrush to Melfina but as the series goes on he becomes more loving and gentle towards her and even makes peace with Gene his enemy before his death.
* Anemone from ''Anime/EurekaSeven'' starts off as a violently psychotic TykeBomb, but grows much stabler in the presence of her handler/guardian Dominic. Late in the series, [[spoiler:he manages to restore her sanity completely through the PowerOfLove]].
* ''Anime/{{Naruto}}'' has Gaara. He starts out AxCrazy but is now a nice mentally stable guy and is actively trying his best to help Naruto, his friend who he once considered his enemy and tried to kill.
* Nina Einstein of ''Anime/CodeGeass'' starts out sane, exhibits SanitySlippage and and then in the beginning of R2 recovers much of her sanity. Later scenes indicate that her insanity was not so much defeated as it was [[MoreThanMindControl redirected]]. [[spoiler:Near the end of the series is where she starts to actually recover.]]
* Hayato Jin in ''Manga/GetterRobo'' starts out as an insane student activist-terrorist with brainwashed followers and gets drunk with power the first time he pilots Getter Robo itself. Though his ruthlessness stays with him through the entire Getter saga, he becomes more pragmatic and well-adjusted.
* ''Anime/DragonBallSuper'': When brought BackFromTheDead in the [[Anime/DragonBallZResurrectionF Resurrection 'F' Saga]], Frieza has suffered severe SanitySlippage, due to [[ShellShockedVeteran PTSD]] from his defeat at Goku's hands and over a decade of torture in an IronicHell. Come the Universe Survival Saga, Frieza is considerably calmer and more stable than he was before. He was able to completely master his GoldenSuperMode in Hell through intense meditation, and is far more pragmatic and patient, to the extent that he voluntarily heals Goku to get him back into the fight with Jiren. Also, [[spoiler:when Whis revives him as a reward for his help in the tournament, unlike last time, Frieza doesn't throw it all away for the sake of [[RevengeBeforeReason revenge on Goku]], and decides to just go back to space and focus on rebuilding his empire.]]


[[folder:Comic Books]]

* In ''ComicBook/BatmanWhiteKnight'', ComicBook/TheJoker is cured of his insanity and the authorities wastes no time analyzing his mental capacity. It turns out his CAT-Scan and IQ tests indicate he's scored beyond genius level intellect, and this has helped him become a very powerful man who can even challenge the GCPD.


[[folder: Fanfic ]]
* In ''FanFic/TheManyWorldsInterpretation'', [[Franchise/{{Discworld}} the Bursar]] recovers his mathematical genius and mental acuity to the point he can hold a coherent conversation with [[Series/TheBigBangTheory Sheldon Cooper]], after being dosed with thorazine.
* In ''FanFic/{{Constellations}}'', Oni Lee starts recovering his missing memories after a chance encounter with Sunny.


[[folder: Literature ]]

* ''Literature/{{Edgedancer}}'' (a novella of ''Literature/TheStormlightArchive''): [[spoiler:Nale's]] SanitySlippage is largely reverse once Lift manages to snap him out of his funk, and he becomes far more stable and sane as a result of the following FreakOut.


[[folder: Live Action TV ]]

* Slade Wilson (Deathstroke) in {{Arrow}}. He was driven insane by a combination of PsychoSerum and tragedy. Later on the PsychoSerum runs out and he's become a lot of more understanding and remorseful.
* Parker from ''Series/{{Leverage}}'' fits this trope well. In the pilot, Nate actually says "Parker? She's insane!" And he means it. As the series progresses, she becomes more normal as a result of the [[TrueCompanions family bonding]] the team experiences as they run jobs together.
* River Tam on ''{{Series/Firefly}}''. PlayedForDrama as it just means her lucid periods get more frequent, so she's more often ''aware'' of her [[ReluctantPsycho insanity]].
* Connor on ''{{Series/Angel}}''. He starts out a warped LaserGuidedTykebomb raised in a hell dimension by a vengeful KnightTemplar and [[SanitySlippage gets worse]]. Angel then uses a DealWithTheDevil to rewrite reality to give Connor a happy life and fake memories. Even after Connor regains his true memories, the knowledge of what Angel did for him keeps him stable.
* ''Series/PersonOfInterest'': Root starts off as an incredibly chipper, sociopathic [[TheCracker hacker]] and hired killer with absolutely no regard for human life. Her experiences with [[MachineWorship The Machine]], [[BigBrotherMentor Finch]], and [[TrueCompanions the rest of the team]] have started to bring her down to a much more stable mindset. She's still rather enthusiastic about violence, but she has clearly learned to care about what happens to people, and she's getting better and better as the show goes on. [[spoiler: Or, she was, [[LoveMakesYouCrazy until Shaw]] [[SanitySlippage went missing]].]]


[[folder: Tabletop Games ]]

* In ''TabletopGame/TheDarkEye'', this can be invoked by removing the character flaws you started out with by using the adventure points awarded at the end of an adventure. Within the game, there is the skill "soul healing", which is equivalent to psychotherapy, and can do this.
* You can try doing this in ''TabletopGame/CallOfCthulhu'' (requires Psychology skill), but ultimately it's just [[CosmicHorrorStory delaying the inevitable]].
* In ''TabletopGame/EclipsePhase'' this can be attempted with mundane therapy or "psychosurgery" that reprograms the software of the brain with nanites. Or failing that revert to an earlier [[BodyBackupDrive backup]].


[[folder: Video Games ]]

* ''VideoGame/AmnesiaTheDarkDescent'': Daniels can regain sanity by staying in light, finding items or completing puzzles. There's also a sanity potion which was cut from the game, but is available for mods.
* ''[[Franchise/{{Metroid}} The Metroid Prime Trilogy]]'' has [[HumanoidAbomination Dark]] [[EvilCounterpart Samus]]. In the second game ''Echoes'' she had basically one mode: [[AxCrazy Bat-shit insane]]. After being [[NoBodyLeftBehind blown to pieces]], [[NoKillLikeOverkill left in a collapsing alternate dimension]] and [[FromASingleCell regenerating thanks to Phazon absorption]], by the time of the final game ''Corruption'', she became sane enough to get the role of TheChessmaster, [[AGodAmI take over the Space Pirates]], and [[GalacticConqueror start a plan for galactic domination]]. Note the word ''enough'' though, the game makes it very clear she's still quite [[LaughingMad mentally unstable]], just toned down from before.
* In the "Forgiveness" path of ''VideoGame/TokyoDark'', Ayami saves the woman she murdered in a [[ArtifactOfDoom Mask]]-induced breakdown months before. Yet another ending ("Purification") involves her destroying the Mask permanently. [[spoiler:Unfortunately, neither of these endings are the canonical one.]]
* A very condensed version taking place over the course of single fight in ''VideoGame/{{Bloodborne}}'' during the battle with Ludwig, the Accursed. Formerly Ludwig, the Holy Blade, first hunter of the Healing Church, he was (like many other characters) transformed into a truly horrendous beast as he sank into bloodlust and corruption, attacking you like a rabid animal. Halfway through the battle with him, you knock him down and his Holy Moonlight Sword falls out of the sheath on his back, radiating light which actually restores Ludwig's sanity, causing him to take up the sword, rise from his PrimalStance to stand upright, and even recover his original title to fight the rest of the battle as a [[MonsterKnight monstrous but powerful holy swordsman]] instead.


[[folder: Web Original ]]
* In Literature/{{Worm}} the government retains the services of a psychiatrist Called Ms. Yamada, who despite being a normal dealing with metahumans of all shapes, powers and stages of sanity manages to help a great deal of them. Her greatest effort is in the epilogues of the story, where she talks a villain contemplating killing ''everyone'' into becoming a hero.


[[folder: Western Animation ]]

* Wanda Maximoff from ''WesternAnimation/XMenEvolution'', who was sent to an asylum by her father Magneto shortly after her mutant powers emerged. Magneto eventually has Mastermind [[MindRape mess with her head]], replacing all her bad memories with good ones so she believes he'd been a loving father. Ironically, she became less psycho and more kind and gentle towards others.
* ''WesternAnimation/TeenageMutantNinjaTurtles2012'': Upon his initial mutation, Slash had been driven crazy and wanted to kill the Turtles, believing them to be holding Raph back from being a true warrior. When he returns in "Battle for New York", he's much more stable, explaining that the mutagen had messed with his head.
** Leatherhead too. In his first appearances, just mentioning the Kraang sends him into a berserk rage. By the team season 3 rolls around, he still hates the Kraang, but he saves it for, y'know, the ''actual Kraang.''
