[[AC: ''Literature/HarryPotter'']]
* In ''Fanfic/FormerlyKnownAsHarryPotter'', Lily is bipolar, epileptic, dyslexic, and she also attention deficit disorder.

* ''Fanfic/PersonaEG'': Fan character Button Mash is portrayed as mentally disabled. This has no plot bearing and comes off more as a cheap shot at the character.

* The reason why Yang hates Panthers so much in ''Fanfic/{{Pawprints}}'' is that her sister Ruby was mawled by one and left wheelchair bound. In ''RWBY'' canon, Ruby has no such injury.

* In ''Warriors'', it's mentioned that Willowpelt has "unusual eyes". What this means is never clarified. In ''Fanfic/WarriorsRewrite'', she has clouded eyes due to being near-completely blind

* In ''Webcomic/ThePowerpuffGirlsReImagined'', Professor Utonium is seeing a therapist for Generalized Anxiety Disorder and Major Depressive Disorder. This isn't in the original ''Powerpuff Girls'' canon. His mental illness plays a huge role in the Powerpuff Girl's and Mojo Jojo's origin stories.
* ''Fanfic/RWBYScars'':
** While she has a scar around her left eye, Weiss can see just fine. ''Scars''[='=]s depiction of Weiss has the event that led to the scar also affect her sight in that eye, rendering it slightly near-sighted. The Weiss from ''Scars'' also suffers from mental health issues, including [[spoiler:multiple suicide attempts and SelfHarm (said scar around her eye in ''Scars'' being the result of Weiss cutting herself rather being a DuelingScar as in canon)]], something the Weiss of canon doesn't.

** Weiss's mother is [[spoiler:schizophrenic]], with her alcoholism partly being self-medication.
** Whitley Schnee is depicted with [[TheSociopath Antisocial Personality Disorder]].
** Coco Adel is shown suffering from PTSD and leg pains due to an injury.
** Downplayed with both Fox and Neo, as ''Scars'' has them as respectively blind and mute before it was confirmed that these respective conditions were canon as well.
* Izuku in ''[[https://archiveofourown.org/works/22304056/chapters/53873806 My Name's Deku, It Means Business]]'' is partially mute due to Bakugo apparently setting off his explosions while strangling him, leaving Izuku's vocal chords damaged.

** Erika is narcoleptic, explaining why she's such a {{sleepyhead}}.
** At age ten, Will was blinded in his left eye due to an Onix attack. This is why he covers that eye.

* In the ''WesternAnimation/StevenUniverse'' fan series ''FanFic/{{Connieswap}}'', Steven needs hearing aids.
* The plot of ''Fanfic/WaitingIsWorthIt'' is about Izuku manifesting a quirk after [[spoiler:becoming crippled and ending up in a wheelchair]]. It is also mentioned that Shota Aizawa was partially blind in his youth while Hizashi Yamada had hearing difficulties. Disabilities due to one's own quirk seem to be more common that one thinks, with [=UA=] having a program to helping their students with these problems.

* ''Fanfic/PokemonResetBloodlines'':
** Anabel is [[CuteMute unable to talk]], due to losing her voice after her parents died in a car accident. Somewhat subverted by the fact that she has developed {{telepathy}} to communicate with people.
** In canon it's never explained why Erika is a {{Sleepyhead}} who falls asleep so often (even mid-sentence). It might be a disorder or it might be related to her grass-type Pokémon. In ''Reset Bloodlines'' she is explicitly narcoleptic.
* Junpei in ''Roleplay/{{Airlocked}}'' loses an arm during the second round and has it replaced with a robotic one. (An OriginalCharacter also loses an eye and later becomes a {{Cyborg}}.) As well, ''all'' the characters develop moderate to severe PTSD over their experience in the DeadlyGame.

* After [[spoiler:being saved from her kidnappers]] after the story in ''VideoGame/Splatoon2'', Callie suffers no apparent issue and is back to her normal GenkiGirl self. In the fanfic ''Fanfic/HerFracturedSpirit'' she's clearly traumatized (even if she tries to [[StepfordSmiler play it off]]) and has PTSD.
* In the ''Lucky Star'' comic ''Webcomic/LonelyKagamin'', Konata inherited her mother's mysterious illness and she is also depressed.
* The ''WesternAnimation/TheLoudHouse'' fanfic ''Fanfic/MySisterLeni'' portrays Leni as being on the autistic spectrum rather then merely being just a DumbBlonde as in canon. [[spoiler:Lisa]] is also later revealed to be autistic as well.

* In ''Fanfic/NotAMonster'', Bowser's son Lemmy is described as having an intellectual disability.

* In ''[[https://archiveofourown.org/works/6045724/chapters/13861744 Going Down Swinging]]'', Neo is mute because she's missing her tongue. In ''RWBY'' canon, Neo doesn't speak and it's vague why she doesn't speak.

* ''Webcomic/SonicTheComicOnline'': In the games, Tikal ascended with Chaos at the end of ''Adventure'' and hasn't appeared since. In ''Sonic the Comic Online'' Tikal is physically transported to the present but she is so traumatized by [[AndIMustScream 8000 straight years of mental torture]] that Ebony mind-wipes her.

* ''Fanfic/AnArmAndALeg'' revolves around Elsa and Anna both being injured at the end of ''Frozen''. Elsa becomes paralyzed from waist down and Anna loses her right arm.

* Izuku in ''[[https://archiveofourown.org/works/22304056/chapters/53873806 My Name's Deku, It Means Business]]'' is partially mute due to Bakugo apparently setting off his explosions while strangling him, leaving Izuku's vocal chords damaged.
