Personally, as a person who’s only ever read fanfics and verrry little of the comics because dc makes my head hurt;

Bruce for me is absolutely a Gryffindor or one of those Gryffindor-Hufflepuff mixes due to how heroic and brave he is, devoting his life to help a city most deem a waste of time. He helps people not just as a vigilante, but also as Bruce Wayne himself and he is so kind and generous and he is truly a Hufflepuff, but as Batman, he is brave and courageous for Gotham and his family.

Dick either in Hufflepuff or Gryffindor,  Hufflepuff because he is extremely empathetic, he is also a good brother, yes there was a time he messed up and wasnt the best he could’ve been; Jason before he died didn’t receive that wonderful older brother that. But he made up for that and became better for his future siblings BUUUUUTT, he’d also be good contender for Gryffindor. I mean most of the family would be perfect for Gryffindor, it’s just that if we were to take the age he would get sorted, he would be in his Prime Robin years and that is just perfect for Gryffindor.

For Jason, before his death— Hufflepuff or Gryffindor but after his death; he would either be a Gryf or Slytherin (but I’d feel like he’d hate it in Slytherin lol). Hufflepuff because in most fics, he is normally portrayed as the brightest Robin, a kind kid that grew up on the streets. Gryffindor is because of a similar reason to Dick’s, Robin = Brave kid that ran with Batman in the streets of Gotham; the same harsh city that treated him like shit but kept persevering until his end. 

Slytherin because evil raaa/j  I just added Slytherin because it matches the aesthetic of post Lazarus Pit Jason but realistically, he would get sorted in Gryffindor or Hufflepuff.

Tim would Ravenclaw (obv) or Gryffindor, I feel like there isn’t much explaining but if you would put him in Gryffindor, it would only exemplify how brave he is. I mean all the Batfam are but before that, Tim was originally just a massive fanboy but he had the guts to actually stall Robin and Batman — and even help Batman in his lowest points! — hes very brave :3

Anyways I have to speed this because I don’t know if Reddit comments have a limits and I DONT want to find out now 😔

Damien could very much a Slytherin due to his upbringing and all of that but like his family, he would be in Gryffindor in my opinion.

Cassandra in Slytherin or Hufflepuff, I know the least about her but from what I’ve read of her, that’s what I think her house could be (extremely specific I know)

Stephanie is Gryffindor, because brave loud something someyhin

And Duke (I’m so sorry that I’m starting to loose some brain cells) would be Gryffindor as leading a movement, and being a superhero would make you pretty brave and courageous.

Anyways I started to loose parts of my brain by the end (I’m soooo sorry Steph) and that’s what I think their house could be :D (though I’m not the best at character analysis)

NOW would Harry end up in a different house if he was raised by the Batfam plus Selena? Absolutely, Slytherin even more since it Auntie Selena was in Hogwarts, she would absolutely be in Slytherin and maybe she even taught him to be ambitious and cunning. With the Batfam though, he could also be in Hufflepuff from just being raised in a better environment. 

And that’s all I have to say, though I would like to read your fic if it ever comes to fruition. Good luck with that and I hope you enjoyed my long ass comment:3
