In honor of Pride Month, have a non-exhaustive list of my queer identity headcanons for every main character in Fire Emblem Three Houses (+ an honorary Shez).
Edelgard - mostly a lesbian. Living embodiement of that one meme that's like "I'm probably nonbinary but I have a job so I can't worry about that right now".
Hubert - that is a trans woman if I've ever seen one. I normally headcanon her as straight (bc tbh we need more transhet rep) but i'm not opposed to other reads of her. She changes her name but I don't have one singular stable name she changes it to every time I draw/write/think this.
Ferdinand - bisexual, but doesn't know it yet. He can be the token cis man of the Black Eagles, I think.
Dorothea - bisexual and absolutely knows it. Either a cis woman or a demigirl (or somewhere along there) depending on the way I feel like writing her at any given time.
Bernadetta - transfem Bernadetta has a very special place in my heart! I personally headcanon her as aroace (or at the very least graysexual + grayromantic). Side note, I don't normally ship Bernadetta with anyone as their characters exist in canon, but transfem!Bernadetta x transfem!Hubert makes more sense to me + feels more fun to ship than the ship of their canon selves.
Linhardt - could not give less of a fuck about gender. I normally headcanon him as agender, aromantic, and asexual. However, agender and toric (attracted to men) Linhardt is also very strong contender. Toric!Linhardt is also demi- or gray-aroace and polyamorous.
Caspar - transmasc Caspar also has a very special place in my heart! I say he's gay/achillean, and also polyamorous.
Petra - sapphic, and mostly gender indifferent. She has more important things to worry about then what the rest of Fodlan thinks her gender is.
Dimitri - that's a trans man. And also bisexual. Started transitioning early enough that when he got super depressed he was able to ride the momentum and keep transitioning. Living in the woods without fantasy HRT for five years was rough on him though.
Dedue - demiromantic and attracted to men. I'm very indecisive about a gender identity. So fuck it, he can be too.
Felix - gay. Has a whole complex about it because of the way he was raised (though the same can be said for like everyone on this list). I also very much enjoy transmasc!Felix, but it's also interesting to explore this with a cis reading of him.
Sylvain - pansexual and transfem, though I flip between fem-aligned nonbinary and binary trans woman headcanons for her. Completely ignores all of their queerness for at least the first half of any given story arc I give them. Goes by Sylv, Sylvi, or Sylvia depending on the specific headcanon I give her.
Ingrid - I love both transfem!Ingrid and transmasc!Ingrid equally. I quite enjoy the narrative of transfem!Ingrid being accepted by conservative Fargeus parents only as far as she's willing to conform to gender stereotypes, but I also love transmasc!Ingrid escaping from the pressure of their family and becoming someone truer to themself. Either way, they're attracted primarily to women.
Ashe - similarily, I love transmasc!Ashe, transfem!Ashe, and nonbinary!Ashe, though I think I enjoy nonbinary!Ashe the most. Bi but attracted mostly to men, demiromantic but also polyamorous.
Mercedes - sapphic. I don't have any specific gender headcanons for her though.
Annette - pansexual and polyamorous! High femme lesbian vibes except she's pansexual.
TBH I don't know the Deer as well as I do the Lions or Eagles, so these will likely be shorter than the bullshit I was pulling out for them.
Claude - transmasc and bi. I like the idea that he transitioned after he left Almyra which is why very few Almyrans actually recognize him.
Hilda - that's my femme lesbian girlboss!
Ignatz - gay man, who struggled a lot with compulsory heterosexuality alongside all of the other societal pressures from his family. Alternatively, transfem!Ignatz, because I feel like discovering that she's transgender would fit in well with her whole story arc.
Rapheal - I <3 trans man Rapheal headcanons. Also he's bisexual.
Marianne - sapphic fem. They can also be a little nonbinary as a treat. I'm thinking either along the lines of like, demigirl, or just plain ol' nonbinary. She/they pronouns.
Lysithea - bi but has bigger things to worry about. I also like transmasc!Lysithea, specifically in arcs where she gets her illness cured and is then like "ok I finally have room to breathe... oh shit I'm transgender.". I may write a fic about this.
Lorenz - there's a not insignificant part of me that's tempted to make him my one single token straight man. TBH I haven't given Lorenz all too much thought. Maybe I should change that.
Yuri - I see so many trans and nonbinary headcanons for Yuri, but my favorite for him is actually just as a gender non-conforming cisgender man. He can have he/they pronouns though if he wants. Also bisexual and polyamorous but somewhere on the aromantic spectrum (he has a lot of self-reflection he's running from).
Hapi - bisexual and polyamorous. Nonbinary - I headcanon them as genderfluid most of the time but there's no actual reason behind that it just feels Right.
Constance - I love transfem!Constance headcanons, but I can personally go either way between her being a trans woman or a cis woman. Pansexual and polyamorous, but a bit too busy to think about that.
Balthus - cis, pan, polyamorous. Not quite as gender non-conforming as Yuri, but I feel like Balthus is kinda everything-non-conforming, y'know?
Church of Serios, Academy Folks, & Shez
Byleth - nonbinary, either bigender or genderfluid. He/she/they. Bisexual & polyamorous. Thinks, at least at first, that everyone is bigender/nonbinary to some degree, and that folks just pick a gender presentation for funsies.
Catherine - BISEXUAL! Local golden retriever lesbian (while also being bisexual).
Shamir - sapphic, at least mostly. Alloromantic asexual.
Alois - trans man. This is purely self-indulgent. Either bi or gay.
Jeralt - as much as I'd like to make him a trans man for self-indulgent reasons, he can be a cis man. Unless we either headcanon Sitri as a trans woman or that Rhea knows how to help two uterus-owners have a baby with both of their genetics. He's bi though.
Hanneman - either a gay man or an aroace man, I can't decide. (Or a gray-aroace gay man. Both is good!)
Manuela - bisexual. I don't really have gender headcanons for her though.
Jeritza - bisexual, but he has more character development to go through before he can figure that out. I feel similarily about any trans headcanons for him - transfem!Jeritza is great! But the Jeritza we see would not know that. To be fair, I've never actually seen any of their supports, so this is just vibes based.
Shez - nonbinary, pansexual, and polyamorous. She/he/they but unlike Byleth I don't actually headcanon her as bigender or genderfluid, just nonbinary. IDK why.
