There could also be new characters created specifically for the fanfiction. These characters might be hybrids of the two universes, having traits from both 'angel bones' and the crossover world. They could play a crucial role in bridging the gap between the two different settings and storylines, adding a new dynamic to the narrative.

One popular one could be 'Soulmates Across Dimensions'. It beautifully weaves the two universes together, exploring how Buffy and Angel's relationship might develop further in new and unexpected ways. It has some great action scenes and emotional moments.

One idea could be a crossover with a detective show. The angels could assist the detective in solving a case that has a supernatural element to it. For example, they might help the detective figure out that a series of murders are being committed by a demon in human form.

One idea could be a crossover with 'Cardcaptor Sakura'. Daisuke could meet Sakura and they could both discover that their magical artifacts have some strange connection. For example, the Dark and the Clow Cards might react to each other in unexpected ways.

One idea could be that the vampires in Buffy's world somehow cross over to the Dark Angel universe and the transgenic characters have to deal with them. They might initially mistake vampires for some new kind of transgenic experiment gone wrong.

Some people like the idea of a Slenderman and Minecraft crossover in fanfiction. Picture Slenderman lurking in the blocky Minecraft landscapes, scaring the players. Another possible crossover is with the Gravity Falls universe. Dipper and Mabel could stumble upon Slenderman during one of their adventures in the strange town. And a crossover with the Resident Evil series would be intense. Slenderman in a world full of zombies and bio - horror threats would create a really complex and terrifying scenario for a fanfiction.

Maybe there's a case where the Bones team discovers a body that has a connection to an old family in Sleepy Hollow. The family has a long - held secret that involves a pact with a dark force. Crane and the Bones team must work together to uncover the truth.

Brennan could analyze the bones in ways Crane never thought possible, while Crane could provide historical and supernatural context that helps the team understand the bigger picture.
