The same character living the same story in a different setting is way different like the classical white Knight war guy in Arthurian myth or the crusades or the us civil war or each world war are way different then you get past world war two or world war one if he’s Russian or Chinese and things get real real different

Like does that setting have a side that’s the good guys or both kind of have a point or the whole war is nihilistic stupid or its like a Hitler versus Dracula kind of situation and how does that character change when fights are long affairs with swords or industrial meat grinders with machine guns and chlorine gas like the last gasp of the noble knight guy was von Richthofen and arguably your chuck Jaeger’s with shreds of that cultural cachet spilling into civilian astronauts and now you have like sociopath spooky operator guys as the war expert people and how does your white Knight gut fit in with each of those and that’s just like stuff closely based on reality how does he cope with fighting a hive mind or giant robots or being a wizard or the same guy but he’s more a science hero macguyvering his way with science magic or breaching the warp core or whatever

You can write the same story again and it’s still good did you ever watch ‘samurai champloo’ it can totally work
