Chris becoming immortalized as a new disorder on the Autism spectrum would be one of the most ironic things ever, given how much he hates being considered a 'slow in da mind' despite, y'know, abusing the fuck out of the handicapped parking permit he got out of it.
It would match his life though. Chris legit constantly foreshadows his own "downfalls."
He had that Sonichu comic where to prove he wasn't gay, he wrote that his blood was discovered to be the cure for gay people, with Chris not understanding that vaccinations function by utilizing a portion of the virus in controlled environments to allow the body to adapt to it in a safer manner, so the vaccine idea that he thought proved he was straight actually did the opposite.
He would later go on to become whatever "trans" monstrosity he is now and describes himself as being married to Magi-chan, a male character.
There were also episodes where he wanted to show how manly he is, then later we got "Stephanie Bustcakes" and Christine as he tried to convince people what a beauty he is.
He also talked about how much he loves his mom and showed us creepy little interactions with her throughout the years, and lo and behold he's banging his mom years later. He was always talking about how he wants to find a boyfriend-free girl, and I mean, technically Barb is boyfriend-free now...
And as you mentioned, some of his most blatantly autistic moments arose when he was - that's right - being called autistic/compared to other "autistics." (aka fake parody individuals) FFS when Asperchu was a thing, he neither understood how blatant it was that everyone knew Asperchu wasn't the original, and simultaneously raged like an autistic child about how autism was better than asbergers, which is like the "winning an argument on the internet is like the special olympics: even if you win you're still retarded" phrase unironically and Chris was truly invested in that.
Basically, if Chris ever denies something, it's bound to happen. I said in another thread discussing if he was a pedophile that simply the fact we were
having that discussion meant there was potential for him to become a "pedophile" (quotes because I doubt he'd genuinely be one, but rather he's so impressionable he'd act as one anyways because someone convinced him it's a brilliant idea) because legit all you have to do is breathe life into the idea and Chris will somehow make it a reality. I stand by that statement cause yeah, dude's a trainwreck and the moment you accuse him of something bad, he'll make it happen.
He's just a sponge that soaks up whatever idea is being presented to him, good or bad. I feel like the only constant throughout all of Chris' mindsets and all the "sagas" through the years is his narcissism, as he'll always spin it in such a way that it's all about him and he's the center of the universe. What was once a Sonichu comic very quickly derailing into it being about Chris' lovequest has now become Chris believing he's Jesus Christ because apparently the only form of media in jail is the Bible.
