Potterlock

The same naming technique may be applied to crossovers - stories that combine two or more fandoms together - so in this case Potterlock is a combination of Harry Potter and Sherlock Holmes fandom.

Fictional characters star throughout Slash, including Catwoman and Wonder Woman and a wonderful alternate-universe Johnlock/Harry Potter crossover (Potterlock) with Sherlock as a drug-addicted pureblood Slytherin and John a Muggle-born Gryffindor dating Hufflepuff Mary.

With Potterlock being such a popular crossover amongst Harry Potter and Sherlock fans, it’s no surprise that these characters slot so effortlessly into the four Hogwarts Houses.
