I'll try and reblog with a link to the film one I find it.

Julian: autistic (I recognize some character traits in him that I have myself, like extreme attachment to a specific item and stoicism)

Bubbles: autistic and ADHD (massive empathy for animals, excessive talking when he's excited, has a bit of a meltdown if things are getting too stressful or overstimulating)

Ricky: dyslexic (this is definitely the most likely hc to be canon) and ADHD (he's very impulsive and quite often struggles with concentrating on certain tasks)

Trinity: ADHD and discalculus (is that how you call it?? Like severe issues with math in particular? Anyways in some clips on the show Trin seems to struggle to sit still and I hc that she can't cope well with frustration, though she's gotten better at managing it as an adult)

Cory and Trevor: autistic (they need very specific instructions in order to complete a task and often seem unaware of other people's emotions, ex: coming up for a high five when Ricky is clearly in a shitty mood lol)

Sarah: autistic (gets upset by even minor sudden changes and is unusually emotionally intelligent)

J-Roc: ADHD (excessive talking and movement, verbal stims)

I'm actually writing a 5+1 fic of this pairing as we are speaking lol I love me some obscure TPB ships. Anyways I'll put in both romantic and platonic hcs! ^_^

-this is actually based off of a rlly cute blooper I found but J-Roc is the only person in the park who can make Julian laugh (like an actual amused laugh, not a lill smile)

-Julian gently smacking the back of J-Roc's head when he's acting ridiculous

-J-Roc is always worried abt embarrassing himself in front of Julian but Julian's so used to these situations already that he doesn't even flinch whenever he catches J-Roc doing something strange

-T finding it super sus that J-Roc is always asking Julian to star in one of his greasy movies because yeah it'd make good money but also why do u seem so overly excited bro???

-J-Roc being personally offended when Julian says he doesn't really listen to music and demanding that the two of them find out just what his taste in music is

-Julian stealing plastic covers for J-Roc to sell his CDs <3

-J-Roc wags out his tongue at Julian sometimes and he has this super long cartoony tongue so Julian has to look away every time to prevent from laughing

-Julian has memorized certain weird vocabulary J-Roc always uses so he doesn't constantly have to ask T for translations

-"knowm'sayin, Jules?"

-"No, I don't know what you're sayin"

-Julian finds the bickering between J-Roc and his mom endlessly amusing

-J-Roc singing a rap about a mystery person for a Valentines Day concert but wait hold that thought why is he describing Julian????

-Julian being unusually dumb as a rock and brushing J-Roc's flirts and longing stares off as just him being J-Roc

-he's not admitting to it, but Julian actually rlly likes it that J-Roc specifically always calls him Jules. It makes their relationship feel even closer with that detail

-Julian coming over to help take care of J-Roc when he's sick (he's actually here for a business scam, but might as well take the poor guy's temperature while he's at it, right?)

-J-Roc learns to pick up on some signs if he's too loud around Julian and adjusts his volume (which is quite hard cuz the man is a walking talking boombox)

-J-Roc trying to be romantic in subtle ways but Julian being oblivious to it

-"hey man, ya wanna come over and listen to the new Snoop Dog CD? ;]"

-"nah thanks man, I've got some weed to sell"
