A crossover fanfiction might have the law - enforcement aspects of both combined. For instance, the NYPD officers from Blue Bloods could learn from the unique ways that the Zootopia police deal with their diverse population of animals. Or perhaps an animal from Zootopia travels to the city in Blue Bloods and causes some chaos due to their different nature, and both sets of characters have to figure out how to handle it.
One popular crossover is with 'Law & Order'. The two shows have a similar setting in the law enforcement world, so it makes for an interesting blend of characters and storylines. Writers can explore how the Reagan family from Blue Bloods would interact with the characters from Law & Order.
Beckett from Castle would probably respect the Reagan family's experience and loyalty. She might learn from their long - standing family traditions in law enforcement. Meanwhile, Frank Reagan would likely be a bit hesitant about Castle's presence at first, but as he sees Castle's dedication to justice, he would start to accept him as part of the team.
A crossover fanfiction could also explore a personal connection. What if a member of the Reagan family was a big fan of Castle's books? And then they end up meeting in a situation where they need to work together on a case. This would add an interesting layer of fan - meets - idol dynamic to the story while also dealing with the crime - solving aspect.
No. 'Blue Bloods' is a family - oriented show. Fanfiction that involves sexual content goes against the spirit of the show and is inappropriate. It also may not be acceptable in the general fan community that values the show's positive aspects.
Well, perhaps there's a cursed object in the evidence room of the Blue Bloods precinct. The Winchesters hear about it through their hunter network and come to investigate. Along the way, they start to bond with the Reagan family members. Danny Reagan could be initially skeptical of the Winchesters' methods but gradually come to respect their skills in dealing with the supernatural. They could all work together to break the curse on the object before it causes more harm.
One idea could be that the magical world of Harry Potter somehow intersects with the police - family - centered world of Blue Bloods. Maybe a wizard or witch commits a crime in the non - magical world, and the Reagan family from Blue Bloods has to deal with it while also trying to understand the magical elements involved. For example, a magical object is stolen and being used to cause chaos in New York City, and the Hogwarts students come to help solve the mystery, with the Reagans providing their non - magical expertise.
One common theme is the collaboration between the two shows' law enforcement teams. Since both deal with crime-solving, fanfictions often explore how the cops from Blue Bloods and the detectives from SVU work together to solve complex cases.
