Within the fantasy world of the Harry Potter series, Hogwarts School of Witchcraft and Wizardry is the most renowned and elite magical school in the entire world (at least if you take the Hogwarts student's word for it), so it would only make sense that the Buffyverse's most renowned and elite team of demon fighters would feel right at home there. The cast of characters on Angel probably know enough about magic and mysticism that they could open their own magical school, but undoubtedly they'd all want to learn from the best too.
So if Angel, Cordy, and the rest of the Angel Investigations team were sent off to Hogwarts, which houses would they all end up in? Each member of the team has their own strengths, weaknesses, and brings their own special something to the team, so undoubtedly each Hogwarts house would be eager to add them to their own ranks.
10 Darla - Slytherin
When it comes to Angel characters and Hogwarts houses, Darla is quite literally a natural-born Slytherin. Yes, the vampire version of Darla is a clear and natural fit for Salazar Slytherin's house, but even human Darla would have only truly fit in Slytherin too.
Darla is manipulative, sneaky, and always knows how to get exactly what she wants, and she doesn't let anything as petty as morality or sentimentality get in the way. She was the Master's favorite acolyte for a reason, and she undoubtedly would be daring and cunning enough to make Salazar himself very proud.
9 Spike - Gryffindor
When Godric Gryffindor was envisioning the kinds of brave warriors that would populate his Hogwarts house, William the Bloody probably wasn't exactly the kind of person he had in mind. However, Spike is undeniably one of the bravest characters in all of the Buffyverse, he's even brave to the point of stupidity sometimes.
Spike loves nothing more than a decent brawl, and for him, the person or thing that he's squaring up against is more incidental than anything. Most Gryffindors won't shy away from a fight when the fight finds them, but Spike would have been one of those kids who was constantly on the lookout for one.
8 Allen Francis Doyle - Hufflepuff
Although most people would probably like to imagine they would be the kind of person to step up to the plate when the need arises, the reality is that many wouldn't be too pleased about the weight of the world suddenly falling on their shoulders.
Doyle was definitely one such person. Like any true Hufflepuff, conflict is not something that comes naturally to Doyle and he'd like to avoid it if at all possible. But when it comes down to the nitty-gritty of making the right choices and getting things done, Doyle more than proves his worth.
7 Connor - Hufflepuff
Connor's conception and existence was a miracle in itself, and he was essentially chosen from birth to be an extraordinary warrior. While he was certainly gifted with the abilities of a champion for the forces of good, his personality is much more of a Hufflepuff than a Gryffindor.
Connor does the right thing and has the heart of a hero, but if he were given the choice, he would probably live a normal human life. He has the strength of a fighter to be sure, but he doesn't want to fight unless he has to. Even when Connor has to take up arms, he is usually not very happy about it.
6 Lorne - Hufflepuff
If anyone in the Buffy and Angel-verse is a quintessential Hufflepuff, then it is Krevlornswath of the Deathwok Clan (more commonly known as Lorne). Lorne may be a demon, but he values peace and harmony over everything else.
Lorne is accepting of nearly anyone and everything, and he finds a way to love or at least tolerate everyone he encounters. Lorne's powers make him a powerful ally for the forces of good and he is a good person at heart to be sure. He would rather avoid getting any blood on his hands, even if the other person more than has it coming.
5 Winifred Burkle - Ravenclaw
Realistically speaking, not only would the Hogwarts student version of Winifred Burkle be in Ravenclaw, she would be at the top of her class. Fred's intellectual powers are so extraordinary that even a literal genius felt threatened enough by her that he sent her to an actual hell dimension.
If Fred only had an extra touch of magic on her side, she most likely would have figured out a way to escape Pylea all on her own. Fred's contributions to the Angel Investigations team were many, and if there was ever a problem that seemed impossible to solve, she was typically the one to solve it.
4 Charles Gunn - Gryffindor
Angel was a show about a ragtag band of warriors fighting for the forces of good, but there was no character who had a truer warrior's heart than Charles Gunn. Most of the Angel Investigations team found themselves thrust into the grand battle of good versus evil against their will, but Gunn voluntarily took the lead in fighting the vampires in his local neighborhood and just continued to ascend in the ranks of fighters for the forces of good.
Gunn often seemed to feel out of place in Team Angel because he never seemed to realize that it was his bravery that made him as extraordinary as the rest of them.
3 Wesley Wyndam-Pryce - Ravenclaw
Before Fred's serendipitous meeting with Angel and the rest of the team, Wesley was the resident brainiac. While Fred probably has the edge in that department, Wesley can definitely still give her a run for her money. In the fantasy world in which the characters from Angel are attending Hogwarts School of Witchcraft and Wizardry, it's pretty much a guarantee that Wes and Fred are the Ravenclaw house prefects.
While Fred has the edge on Wesley in general, no one has Wesley beat when it comes to an encyclopedic knowledge of the magical world, which Rowena Ravenclaw surely would have loved.
2 Cordelia Chase - Gryffindor
Cordelia Chase may not have been born a hero, but she was certainly born a fighter. Even before working for the powers that be became her full-time job, Cordy was never one to back down from a challenge and always stuck up for herself, even in the face of terrifying danger.
Come on, we're talking about the girl who managed to talk her way out of being killed by a vampire because she was just so confident and intimidating. Cordelia is a perfect fit for Gryffindor, and undoubtedly her experience at Hogwarts would have allowed her to channel all of that bravery in the best way possible.
1 Angel - Gryffindor
The beginnings of Angel's human life definitely didn't make him seem like Gryffindor material, and his transition into the vampire Angelus made him even more unsuitable. That said, once Angel was cursed with his soul, he transformed into a Gryffindor through and through.
Angel exhibits the kind of selfless heroism, bravery, and pure intentions that Godric Gryffindor probably dreamed would define the students of his Hogwarts house. If Angel actually wound up at Hogwarts School of Witchcraft and Wizardry, he undoubtedly would have become the kind of heroic legend that Gryffindor kids would have learned about for centuries to come.
