-a bigger prosthetic as a kid cuz i've always imagined that typhon probably wanted to make something troy could grow into so they could spare parts and resources they had on nekrotafeyo hence why he's so used to his in game one

-crooked teeth he later on fixed with his golden veneers or whatever

-don't think typhon had much skill or care for the twins' hair or braiding tyreen's so both ty and troy wore it very short for like. a while. troy probably had an emo phase in his teens and after that because his bangs are loooong man

-in the au troy survives and crimson raiders can't find a better place for his powerless self than back on pandora where he's forced on a hellish summer camp trip to boom town and helping the b team get rid of the last bits of COV's legacy. very much depressed because ty is dead and often sick but tannis made sure he survives with his lacking physiology (threat). grown out hair and a tribute tattoo to tyreen instead of the vanished siren markings. something star related again probably because he's sentimental like that. brick also confiscates his prosthetic and throws it off a cliff and it later gets replaced with a slicker nubby one just so the function in his shoulder joint doesn't atrophy. i imagine he manages to become good friends with the b team but tina kinda haunts him because oh you're crazy and you love women... you kinda remind me of my sister... that's cool...
