YIPPEE THANK YOU THANK YOU ok so wars you say... hehehe...
(These are gonna be in no particular order btw)
-Pre-war he was a really sunshiny guy: he was raised in a poorer village far from the castle, so he didn't have much as a kid, which is why his mom always told him to be grateful for everything he had. He went around helping strangers and doing extra work to help pay for his family :)
-Wars and Linkle are twins, though he's a few minutes older than her (and he NEVER shuts up about it)
-His dad was an army general who died when Wars was around 14 or 15. Wars, being willing to do anything to help his family, actually volunteered for the army at age 16. He was one of the youngest people in his battalion.
-The first time that Hylian soldiers turned and joined Cia's side, Wars refused to kill any of them. It was only when he was beaten and bleeding and on the brink of death, surrounded by multiple turncoats, that he made the decision to save himself and fight back. For the next few days after, he wouldn't speak or interact with anyone, the guilt being too much for him.
-Also: he'll act really flashy and flirty towards people, thinking that he has to as the hero of hyrule, but when it comes to someone he GENUINELY likes he'll be the biggest mess you've ever seen
-Bisexual with a very slight preference towards men!
-Post-war, he has VERY extreme trust issues after several of his best friends turned on him during the war
-When he first saw the Chain, he had thought that they were assassins sent to kill him and almost cut off Time's head in their first encounter (Sky needed to bring out the master sword to convince him that they were allies).
-he has the most big brother/little brother dynamics you'll EVER see with wind.
-Wars is, of course, the closest with Time and Wind, considering he knew them during the war (as Mask and Tune), but eventually he also becomes close with Twilight and Legend
-Also fun little thing I like to think: Wars actually has messy, thick, slightly wavy hair that he would straighten each day during the war. With the chain, though, he doesn't have that time (in fact, his hair actually grew to almost shoulder-length, and he HATED it)
anyway yeah that's probably not all of it but it's all I can think of right now!! (It's also probably barely coherent... my bad about that). but THANK YOU FOR THE ASK!!!
