A cool concept would be if the werewolves from Twilight end up in Pawnee's forests. The Parks and Rec team has to deal with reports of strange wolf - like creatures. Tom Haverford tries to turn this into a business opportunity by creating a 'Werewolf - Watching' tour. April Ludgate, of course, is secretly excited to meet real - life werewolves and tries to befriend them.
A great plot idea would be that a new park is being planned near Scranton, and the employees of Dunder Mifflin get involved. Michael Scott tries to take over the project from Leslie Knope, thinking he can do a better job. Meanwhile, the other characters from both shows interact in hilarious ways, like Andy Bernard trying to serenade Ann Perkins with his acapella group.
Ron Swanson and Jacob Black. Ron is all about his manly ways and love for meat and simplicity. Jacob, as a werewolf, also has a sense of masculinity. They could have a competition over who is more manly. Maybe they start a wood - working project together, but Ron is constantly annoyed by Jacob's werewolf - related absences when the moon is full.
One interesting parks and rec fanfiction could be about Leslie Knope's further adventures in Pawnee after the show ends. Maybe she takes on an even bigger project like building a huge park complex that combines all kinds of attractions.
The different work cultures colliding. The laid - back and community - focused environment of Pawnee's parks department in 'Parks and Rec' is so different from the corporate, paper - selling world of Dunder Mifflin in 'The Office'. When the characters from these two worlds meet, there are so many opportunities for humor and drama. For example, when the Pawnee crew tries to understand the strict sales targets at Dunder Mifflin.
Another good pairing could be Jim Halpert and April Ludgate. Jim is known for his dry humor and pranks, and April has her own brand of dark, sarcastic humor. They could team up to play some really elaborate pranks on the other characters from both shows, and their banter would be really entertaining.
Well, for a Twilight and It crossover fanfiction, you could start with the setting. Suppose the town of Forks is somehow connected to Derry. The vampires in Twilight are often in search of new territories. What if they stumble upon Derry which has its own dark secrets in the form of Pennywise? The Losers Club could initially be terrified of the vampires, thinking they are some new form of evil. But then they realize that they might need to work together to defeat Pennywise who sees the vampires as new prey. It could be a story full of mystery, horror, and unexpected alliances.
One popular theme is the development of the relationships between the characters. For example, the friendship between Leslie and Ann could be explored further in fanfic. Another theme is the behind - the - scenes adventures in the parks department that we might not have seen in the show. And of course, there are fanfics that focus on the political campaigns and how the characters deal with all the chaos and challenges in that aspect.
One idea could be that Naruto characters enter the Twilight world and are shocked by the existence of vampires and werewolves. For example, Naruto himself might be intrigued by the different powers and try to understand the complex relationships between the Cullens and the werewolf pack. He could use his ninja skills to interact with them in unique ways.
One idea could be a story where the characters from 'Descendants' end up in the 'Twilight' world. For example, Mal could meet Bella and they could form an unlikely friendship. Mal might be intrigued by Bella's relationship with Edward and the whole vampire - human dynamic in the 'Twilight' world.
A cool concept for twilight and flash crossover fanfiction could be a time - travel aspect. What if a character from The Flash travels back in time and accidentally alters the history of the Twilight world? This could lead to all sorts of chaos, like vampires ruling the world instead of just being in hiding. Or, a Twilight character could use the Flash's speed - related technology to gain an edge in their own battles, like using it to quickly escape from a werewolf pack.
