I think my Braviary might be autistic because it has a lonely nature but it bred with Staravia in the daycare. It's also very slow (259 speed) and has a very low special attack (intelligence). I don't know about you, but i think an autistic Braviary is kinda cute because it's a brave warrior who will fight for everything even if it's injured.
Do you have any autistic Pokémon?
