OK, so here is an interesting one, I've had this idea for a while. Basically, the plot of Hazbin Hotel happens in the Harry Potter universe, so here's the rundown, in Harry's 4th year, Voldemort and his Death Eaters gain immunity from the ICW but only if he stops killing Purebloods and Half-Bloods. which leaves the muggle-borns with the 'Exterminations'. Hermione wanting to do something about it starts the Hazbin Hotel to redeem Death Eaters.
