I don’t care if it “““DoEsN’t FiT wELL””” with your Stucky Coffee Shop AU, unless a fic is exclusively pre or during the war then he should be an amputee and if a fic is exclusively pre-war then Steve should be disabled because that’s what he was pre-serum. The reason why this is so important to me is because it’s important to have representation for disabled characters and we can’t just erase that.
The only time when neither one of them were disabled was during the few years between Steve getting the serum and Bucky falling off the train.
Also, fun fact, the type of amputation that Bucky has is either a shoulder disarticulation or (more likely considering how far the metal arm goes into his shoulder) a forequarter amputation.
And now, here are some suggestions for how to explain why his left arm and shoulder are missing: Cancer, him still being a war vet who lost it in action, an accident involving heavy machinery and bad safety precautions, a very large and extremely infected wound in his shoulder or the “very revolutionary” idea of just not saying how he lost his arm but still referencing every once in awhile that it’s missing and how he’s affected by it.
