The humor mash - up. Brooklyn 99 has its own brand of humor, and when it's combined with another show's humor in a crossover fanfic, it can be truly hilarious. Like if it crosses with 'Arrested Development', the dry humor of that show along with Brooklyn 99's fast - paced jokes makes for a really entertaining read. The fanfic writers often play with the comedic timing and styles of both shows to create something new and funny.
The different settings that get combined. In a 'brooklyn 99 crossover fanfic' that crosses with 'Fargo', the dark and gritty setting of Fargo mixed with the comical Brooklyn 99 vibe creates a whole new atmosphere. It allows for unique storylines that you wouldn't get in either show on its own.
The character interactions. When Brooklyn 99 characters cross over with others, it's always exciting to see how they'll get along. For instance, if they cross over with a show like 'New Girl', seeing Jake's detective skills contrasted with Jess's more whimsical nature can be really engaging.
The most interesting part is seeing how Izuku's character adapts to different universes. For example, in a crossover with the Naruto world, Izuku might learn chakra control, which is very different from his own quirk - based abilities. It's like seeing a fish out of water in a new and exciting environment.
In many 'thundercats crossover fanfic', the new storylines that emerge are really cool. When they cross over with something like the Guardians of the Galaxy, the Thundercats' sense of honor and the Guardians' more laid - back attitude create a contrast that leads to interesting adventures. Also, the way the fanfic writers combine the powers and abilities of both sets of characters is exciting.
The mixing of different power sets. For example, Buffy's slayer strength and combat skills combined with Thor's god - like powers make for some epic fight scenes. It's fascinating to see how they would interact in a battle situation.
The most interesting part is seeing the different power systems interact. Nen from HxH and Quirks from BNHA are so different. For example, how would Gon's Jajanken deal with a villain's powerful Quirk? It creates a lot of unique battle scenarios.
The combination of powers. You get to see the superpowers of the X - Men, like Jean Grey's telekinesis and Cyclops' optic blasts, interact with the powers of the Avengers such as Thor's lightning and Captain America's super - strength. It makes for some really epic battle scenes.
If it's a crossover with 'Game of Thrones', Tyrion Lannister would be a very interesting character to include. His wit and intelligence would play well against the characters in Brooklyn Nine - Nine. He could outsmart some of the criminals while also getting into comical exchanges with Jake and the gang. Another great addition would be Arya Stark. She could show off her combat skills and stealth, and it would be interesting to see how she interacts with Rosa, who also has a tough - as - nails attitude. Also, Jon Snow could be included. His sense of honor and leadership could have an impact on how the precinct operates, especially when dealing with difficult cases.
One idea could be a crossover with 'The Office'. Picture Holt trying to implement his strict rules in the Dunder Mifflin office and the chaos that would ensue. Jim could play pranks on the Brooklyn Nine - Nine characters, while Terry would try to keep everyone in line. Another idea is a crossover with 'Parks and Recreation'. Leslie Knope and Jake Peralta could team up to solve a mystery that involves both Pawnee and the 99th precinct. They would have very different approaches, but it would be fun to see them work together. A third idea could be a crossover with 'Stranger Things'. The Brooklyn Nine - Nine gang could find themselves in Hawkins dealing with the Upside Down. Scully and Hitchcock would probably be the first ones to run away from any demogorgons!
The combination of powers. For example, seeing Zoro try to fight against a Hollow with his swords in a One Piece - Bleach crossover is fascinating. His swordsmanship could be contrasted with the way Soul Reapers use their zanpakutos.
The merging of the two different settings. Gravity Falls has its own spooky and mysterious forest and town, while Undertale has the Underground with all its unique areas like Snowdin and Hotland. When these two settings are combined in a fanfic, it creates a whole new world full of possibilities. For instance, a fanfic might have a scene where the characters are exploring a part of the Underground that has been influenced by the mystery of Gravity Falls. This could lead to some really unique and unexpected story developments. It also allows for a lot of creativity in terms of how the rules of both universes interact.
The character interactions can be really fascinating. Imagine Mikasa Ackerman teaming up with a powerful Pokemon like Charizard. She could ride on its back and use her combat skills along with Charizard's fire - breathing abilities to take on Titans. Also, the idea of the Pokemon having to adapt to the world of Attack on Titan, where there are different rules and a lot more danger, is an aspect that can be explored in many interesting ways.
