i saw a couple years back that someone hc'ed Leon from pokemon SWSH as dyspraxic, and i remember adopting that hc and running with it. i have no clue where the original post is now, but i'll just state my version of the headcanon: he's very dyspraxic, might have some other conditions going on but i can't be bothered to be consistent in deciding whether he has inattentive ADHD or not, but basically, he pretty much doesn't have an internal map. or any coordination. people tend to be surprised that his sense of direction is that bad, but nowhere near as surprised as they are by his incredible lack of coordination. he cannot go five minutes without spilling something. he's broken his hand several times from accidentally swinging it into doors. he lives on caffeine and gifted kid burnout. he is blorbo from my shows with incredible insomnia and a stunning absence of motor skills. he struggles to distinguish left and right. he has no sense of physics. his only way of working down a familiar route is muscle memory – turning the wrong way gets him totally stranded. he hates knowing he was always the kid who got lost. he has a guilty pleasure in getting lost and wandering. erring anyway. he doesn't get to err in any aspect of life anyway. he's always lost somehow. not that he's allowed to admit it.
Hop also has dyspraxia, but it's much milder, so Hop could get through life undiagnosed without any major trouble. On the other hand, Hop's ADHD is considerably more affecting than Leon's, so they kinda traded conditions. Leon's coordination is generally better than his spatial memory (read as: both are not great), while Hop's spatial memory is fairly okay, but his coordination isn't fabulous.
nobody knows how Leon's capable of battling so well with an incredibly rudimentary understanding of physics and extremely poor mental rotation skills. he claims he battles with his gut, working on feeling, impulse, drive—some kind of spark that crashes through him, telling him what's to come, where to go. basically, he works wholly on instinct and closeness to his pokemon. in this regard, he's a foil to blue, who has an excellent understanding of physics, but horrific coordination, and thus also an instinctual approach to battle.
25 years had to pass... 25 years of adventures, challenges and obstacles, growth and learning... And today those 25 years ended. WE CAN FINALLY SEE HIM AT THE TOP, ASH IS THE WORLD CHAMPION!!! I have already seen the chapter 3 times, and god, WHAT A CHAPTER, the animation, the drawing, the soundtrack, everything was incredible. Really, how nice it is to see one of your favorite characters, whom I have seen all my life, achieve his goal.
