Character relationships are another popular theme. There could be friendships or even romances developing between characters from the two shows. Maybe a detective from SVU forms a close bond with a member of the Reagan family while working on a case together, and the fanfiction delves into that relationship's growth and challenges.
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.
Another option is to join fanfiction communities or forums dedicated to either Blue Bloods or SVU. Members often share their favorite crossovers or might even write their own. You can interact with them and get some great recommendations.
Another theme might be redemption. A character who has been through a 'black and blue' situation, like being beaten down physically or emotionally, might be on a journey of redemption. They could be trying to make up for past mistakes or heal from their traumas.
Another theme is the exploration of new relationships. Characters from different shows meet and form friendships or rivalries. It can be really interesting to see how personalities mesh or clash. Also, there's often the theme of a greater conspiracy that spans across the shows' universes, which forces the characters to work together to solve it.
Another theme is sacrifice. Brothers in the show are often in dangerous situations due to their jobs. In fanfiction, this can be exaggerated to show how one brother would sacrifice his own well - being for the other. It could be giving up a promotion to protect a brother's reputation or taking a bullet for him in a dangerous encounter.
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.
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.
The theme of justice also runs through a lot of Jamison Reagan fanfics. He is shown to have a strong sense of right and wrong, just like the rest of his family. But in some fanfics, he might take a different approach to achieving justice compared to his more traditional family members, which makes for some great storytelling.
A frequently seen theme is the interaction between different character personalities. In a crossover with 'Naruto', for instance, the determined and often hot - headed characters from 'Naruto' meet the more reserved or complex characters from 'Blue Exorcist'. This leads to some interesting character development and relationships. Also, the theme of good vs evil in a new context is common. Since both the original 'Blue Exorcist' and the crossed - over series usually have their own ideas about what is good and what is evil, it creates new scenarios to explore this concept.
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.
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.
