I have a lot of headcanons specifically about mental illness and illness in general because I demand representation and I’ll make representation since it doesn’t happen. I figured I’ll list a few off the top of my head, and these are the just the disabled, neuroatypical, and neurodivergent headcanons.*

*I really don’t know enough about conditions on the autism spectrum, so I say “autism” but I mean something along that spectrum.

Pearl ((Steven Universe)) - Autism, OCD

Papyrus ((Undertale)) - Autism

Amethyst ((Steven Universe)) - Borderline Personality Disorder

Connie ((Steven Universe)) - Social Anxiety

Onion ((Steven Universe)) - Autism

Remus Lupin ((Harry Potter)) - Narcolepsy

Kazuaki Nanaki ((Hatoful Boyfriend)) - Narcolepsy

Caitlin ((Pokemon)) - Narcolepsy

Wally ((Pokemon)) - Avoidant Personality Disorder, Generalized Anxiety Disorder, Lupus

Wirt ((Over the Garden Wall)) - Generalized Anxiety Disorder, Insomnia

Izzy ((Total Drama)) - Histrionic Personality Disorder

Noah ((Total Drama)) - Major Depressive Disorder

Harold ((Total Drama)) - Schizotypal Personality Disorder

Draco Malfoy ((Harry Potter)) - Dependent Personality Disorder

Luna Lovegood ((Harry Potter)) - Autism, Chronic Sleep Paralysis

Neville Longbottom ((Harry Potter)) - Social Anxiety, Avoidant Personality Disorder, Major Depressive Disorder, Insomnia

I could keep going on indefinitely but I’ll stop for now. Basically, everyone is now neuroatypical and/or neurodivergent. Because representation.

Also comorbitidty is a very common occurrence with both mental and physical illness so let me just make it abundantly clear that at the very least, I believe Pearl has OCD and PTSD, with possible other illnesses.

I have a headcanon that Pokemon that evolve my trading are able to evolve in the wild by completing long migrations and evolve at the end of said migrations because of all the experience and new perspectives they’ve gained.

Headcanon: 

Mike stopped believing in Santa at age 8.

When Mike was 7, all he asked for was to be a normal boy; for his personalities to go away.

He got a Nerf gun from Santa.

Headcanon that’s not really a headcanon but it gives me feels:

Svetlana was the original personality. She was there first. Though, being born into a man’s body, she realized her transgender identity at a young age. Wanting to be a normal boy like everyone wanted her to be, Mike came into existence. The personality Svetlana’s parents had wanted. Svetlana had been given the name Mike at birth, but now she introduced a face for the name. She receded into Mike’s subconscious, choosing to live there, away from the expectations and pains of living in the real world. It was there that she began her gymnastic career, having an affinity for such a thing. Mike became convinced he was the original. Svetlana created the other personalities to keep her company. She based them off of things and people Mike saw throughout his life. Chester was Svetlana’s take on her grandfather, Vito parodied the Situation she saw on Jersey Shore one afternoon, and so on. Svetlana wants Mike to keep control, because he can best live out the life she was meant to leave. If she can’t live in peace, she wants him to.

So I assume that each alter of Mike’s has their own recollection of memories and whatnot, considering Vito mentioning his uncle Vinnie, and Manitoba mentioning having a wife.

Headcanon:

Svetlana hates the stereotype that all Russians do is drink vodka and dick around. She is 100% sober all the time because her father (as she recalls) was a heavy drinker and just sort of sat around like a lump all day every day. He never even looked at her, he just sat there, staring at a static-y TV and drinking. Svetlana’s mother had to shoulder the burden and provide for the family, which made Svetlana despise her useless father. “Lips that touch the alcohol will not be touching mine!” she announces proudly when asked about the subject.

Headcanon: Mike’s mom is always doting on him and is 100% supportive of him and his life with MPD. She gets along well with his personalities and just treats his MPD likes it’s a normal occurrence.

His dad means well, but he just isn’t as good with dealing with it and often says the wrong thing. He shows he cares by working two jobs to support all the medical bills, prescriptions, and counselors/doctors for Mike. Mike often feels guilty about this, because his father isn’t home a lot due to all of the extra work.

Headcanon: Although all of Mike’s alters would like to have control over the body, Svetlana has more or less given up. Even if she were to be able to be the main personality, the thought of having to live out life in a man’s body sounds just as enslaving as her current situation. She puts all of her energy into her gymnastic skills because it’s better to do that than to brood about her predicament- stuck in a man’s body with five men until the day Mike dies.
