i had a weak knee, chronic pain, and somewhat reduced vision in my left eye as sabo (one piece), following my ship being shot. those chronic pains were added to fairly frequently in all of my timelines, but less so in the spades timeline than my canon and near-canon timelines. being a revolutionary was incredibly taxing on my body, particularly because i did the flashy work a lot.
as tails (sonic), shiro (kill la kill), and dave lalonde (homestuck kidswap), i had a very weak immune system; as tails, i was leucistic, and as dave lalonde, i had sun sensitivity issues, but with my eyes and skin. as andi (knights of guinevere), i'm canonically chronically ill because of my work.
as shouto (bnha) and zuko (atla), i had greatly reduced vision in my left eye; it was more extreme as zuko. by the time i retired from hero work (as shouto), i experienced chronic pain often; my leg was shattered during a rescue-turned-fight, and i had really bad arthritis in my hands as i aged.
as fuyuhiko (sdr2/danganronpa), i was missing an eye. as raiden (mgs2), i was missing a leg! (i didn't get fully robo'd). and, finally, as both bucky barnes (mcu) and gaige dimartino (borderlands), i was missing an arm.
