Batwoman is a show full of very bold personalities. Though it’s the newest addition to the Arrowverse, the show’s heroes and villains have proven to be some of the most interesting so far. While Kate Kane works to help the people of Gotham in her cousin’s absence, her own sister wrecks havoc as the unhinged Alice. Given how different these twin sisters approach life, both public and private, it’s probably no surprise that, like Harry Potter’s Padma and Parvati Patil in the novels, they would have wound up in different Hogwarts Houses.
Kate and Alice are only the tip of the proverbial iceberg. Everyone in Kate’s immediate circle plays specific roles to the public while still hiding who they are. That could make them all Slytherins, except for the fact that not everyone in Kate’s life is motivated by their ambition. Surprisingly, even the villains don’t even end up in Slytherin very often.
Luke: Ravenclaw
Luke’s family legacy is technology, knowledge, and being the one in the shadows who makes the hero look good. His commitment to that family legacy, and the Wayne estate while Bruce has been missing in action, could land him in Hufflepuff. His sheer love for his technology, however, paints a different story.
Luke is at his most excited when augmenting new technology or discovering the secrets of an existing piece of technology. He takes it personally when Batwoman loses, or breaks, something in the field. He’s certainly a Ravenclaw who takes pride in his work.
Catherine: Slytherin
Catherine is like Icarus, flying too close to the sun. She means well, but she uses nefarious means to achieve her goals and ends up burned.
When Catherine sees Kate and Jacob suffering in their constant search for Beth, she gives them an out, letting them believe Beth is dead so they can grieve. Catherine sells her technology to criminals in order to fund research for humanitarian projects. She wants to do good things, but she does horrible actions to achieve her goals. Catherine fits right in the Slytherin house.
Jacob: Gryffindor
Jacob’s goal is to make the world a safer place. He doesn’t always achieve that goal because, like Catherine, he sometimes does bad things for the right reasons. He is rigid in his belief system though and can’t see other points of view when they’re presented to him.
Jacob’s inability to bend - and his own belief in heroics - makes him fall right in line with Gryffindors. Just like a Gryffindor, Jacob allows his own emotions to guide him, like his anger at what Beth became dictating how he treats Kate, Mary, and Alice.
Mouse: Hufflepuff
Despite his villainous streak, Mouse doesn’t have the same ambition as bad guys in Gotham. He doesn’t want to rule the city; he wants to help Alice get her revenge.
Mouse has been by Alice’s side since she was still Beth, hidden away in a secret room in his house’s basement. Alice gave him freedom from his overbearing father that he couldn’t achieve on his own. As a result, his entire life is built on loyalty to her. Mouse is as Hufflepuff as they come.
Alice/Beth: Ravenclaw
Alice’s scheming might seem very Slytherin, and her obsession with her family might seem very Hufflepuff, but she’s surprisingly a Ravenclaw.
She has very specific plans. Alice has contingencies for her contingency plans. She never leaves anything to chance, which is why she gets away with so much in Gotham. Alice understands how her targets think better than they do, giving her an edge over her enemies. She’s knowledgeable, a strategist, and able to adjust her plans in the blink of an eye. Besides, this is a woman who placed all of her hopes and dreams in Alice’s Adventures In Wonderland as a little girl. A girl who uses a book to save herself when she’s at her most vulnerable has to be a Ravenclaw.
Tommy: Slytherin
He only appeared in a single episode of Batwoman, but Tommy Eliot certainly made an impression. As a legacy DC comic book character, the audience was already primed to distrust him. They weren’t wrong.
As someone out to make sure he could overshadow Bruce Wayne and bring down his alter ego Batman, Tommy wasn’t exactly the heroic type. He was focused on ambition and revenge. That ambition blinded him to the fact that Batman wasn’t in Gotham. He was a shortsighted Slytherin, unlike Catherine, not playing the long game.
Julia: Gryffindor
Like Tommy, Julia Pennyworth has only appeared in a single episode of Batwoman so far. She came in as a surprise and left after lending a hand to the hero. Julia was willing to step into a situation she knew little about and put her own life at risk to save Kate’s secret. That sounds pretty Gryffindor.
Considering Julia also lives a life of adventure, traveling wherever her missions take her, and seems to genuinely love it, she’s a perfect fit for the house.
Mary: Hufflepuff
Mary has a little bit of Slytherin in her. She lives her life as a society girl sharing almost everything on social media. In reality, she’s a med student running a secret clinic and hiding how smart she is from most of the people around her. Mary’s intelligence could sort her into Ravenclaw, but it’s her need for connection, and her commitment to helping others, that places her in Hufflepuff instead.
The most important thing in Mary’s world is her family. She wants Kate to think of her as her sister, and she wants her family to be a united front. Mary also wants Gotham to be a level playing field, which is why her clinic serves everyone regardless of which side they’re on.
Sophie: Slytherin
Sophie does what she has to do in order to achieve her dreams. There’s no shame in that. Sometimes, that means the people around her get hurt, which is where her pain comes from. Sophie might not like it, but she’s definitely a Slytherin.
Her ambition meant she spent most of her adult life lying about her relationship with Kate - even to her current boyfriend. Sophie has locked parts of herself away to make sure she gets the job she wants, to make sure she’s safe, and to make sure she never is put in a position that could emotionally harm her. The sorting hat could still change its mind about her, but such strong self-preservation instincts belong to Slytherins.
Kate: Gryffindor
Kate Kane is a lot like her father. When she gets an idea in her head, she can’t let it go, and she doesn’t want to listen to anyone else challenge it. That being said, Kate is also a champion of the people, despite her privileged life, and that helps determine her Hogwarts house as Gryffindor.
She’s never done exactly what’s expected of her, always chasing risks and wearing her heart on her sleeve. That includes her transformation into Batwoman. There isn’t a stronger Gryffindor in the series than Kate.
