Hai !! I just saw your overthrown Ozpin art and I am thus very curious about this AU 👀 What changes from canon ? Does Ozma still reincarnates ? When did things go wrong ? What is his main goal ? And what is he like personnality-wise ?
okay, SO, about the overthrown au (thank you SO much for asking i've been wanting an excuse to infodump abt this au for a while)
what changes from canon- well, a lot of things are the same, like oz still reincarnates, though things in canon are only the same up til the time of volume 2. ozpin's backstory is, of course, still the same! though the story takes place over a FAR longer period of time than in canon, that is, it takes place ~17 years, from v2 onward.
as for what/when things go wrong, sometime prior to the v2 dance, ozpin is approached by a councilman who wants his seat, and threatens ozpin that if he weren't to give up his seat on the council (and thus stop being headmaster), that all of his secrets would be leaked. ozpin naturally doesn't believe him, but this bites him in the ass a week later when salem makes a broadcast to the entirety of remnant, leaking ozpins backstory, but twisting it to favor her and make ozpin into the bad guy. the vale council quickly decides to have ozpin executed, and it almost succeeds, but ozpin escapes and is officially exiled and on the run for around 2 years. sometime before ozpins escape, qrow and glynda are killed, and naturally, ozpin grieves. oz is... very shaken up by what's happened to him, to his friends, as well as ironwoods and leo's betrayal (ironwood was fairly easy to convince oz was bad). so his mental state starts crumbling the longer he's on the run.
his main goal is still the same, at least for a while! though he's a lot more ruthless and forceful about it. since everyone seems so willing to believe oz is the bad guy, ozpin goes out of his way to BE the bad guy. at some point he teams up with roman, and gets cinder, emerald, mercury, watts, and tyrian on his side, and he even starts 'taming' grimm (i.e. scaring grimm into submission) to work alongside him. during the 41st vytal festival, ozpin takes over similar to how cinder did (though instead of the screens being red with a queen chess piece, they're green with his gear symbol!) and completely takes over beacon and thus vale. oz basically goes out of his way to be bad, for several reasons, and he HATES having to be the bad guy but he'd rather die than admit that to himself.
this is also where things start VERY much diverging from canon. the biggest example is oscar! sometime after ozpin takes over vale, and after he's destroyed some random village he decided to take his anger out on, he finds a little baby oscar and decides to take him in to raise him to be his future successor. oscar is also a ram faunus!
as for ozpin's personality- well, he is EXTREMELY different from canon. he's loud, angry, vulgar, the polar opposite of canon. he's also extremely fucked up and very controlling. he's a bit (a lot) of an alcoholic, and smokes a lot, and he can get VERY violent. the biggest example of ozpin's violence in this au is, sadly, oscar. when oscar was around 5, ozpin hit him for the first time, and very quickly it spiraled into abuse, and only got worse as the years dragged on. ozpin is also violent with the newly-revived qrow and glynda (yes, revived, ozpin resurrected them in a sudden burst of desperation and magic. he can't do it again, even if he wanted to). suffice to say, they aren't happy with oz, but can't leave because ozpin has the ability to control them whenever he wishes.
whoops, this got a bit long kaljnkjdsn, uh!! feel free to ask any more questions!! either for more stuff about the overthrown au, or just to elaborate on something! i looooove talking about this au tbh,,
