The character relationships are also very unique. You can have unexpected friendships form, like between the mischievous Loki and the equally sly Uma from the Descendants. Or romances that cross the two universes, which add a whole new layer of intrigue and drama to the fanfiction.
The unique combination of different universes. For example, when Daleks cross over with something like Star Trek, you get to see how their extreme xenophobia plays out in a universe with different alien species and a more diplomatic approach. It's like mixing oil and water in an interesting way.
Character development is another great aspect. In these crossovers, characters from both universes often have to step out of their comfort zones. Percy might have to deal with the more cut - throat and modern world of the Avengers, while the Avengers have to understand and accept the existence of magic and gods. This forces them to grow and change in new ways, which is always exciting to read about.
There's also 'When Descendants Join the Avengers'. This fanfiction focuses on how the Descendants integrate into the Avengers' daily operations. It shows their growth as they learn from the more experienced Avengers. Characters like Carlos become more confident as he takes on tasks with Iron Man, and it's really heart - warming to see their relationships develop.
Character interactions are also unique. For example, Naruto's positive and determined personality clashes and then meshes with the often more complex and morally grey characters in the Overlord world. This can lead to some really interesting character development arcs, like a cynical Overlord character starting to believe in Naruto's ideals of friendship and hard work.
The most unique aspect is the clash of different universes. For example, if it's a crossover with a fantasy world, seeing Boba Fett's high - tech gear against magic is really cool. His jetpack and blasters seem out of place but also very powerful in a different context.
The character interactions. When different universes cross over, seeing how characters like Iron Man interact with, say, characters from the Star Wars universe (in some really creative crossovers) is fascinating.
The cultural clash is also fascinating. The ninja culture from Naruto, with its honor and clan systems, meets the high - tech, virtual world of Code Lyoko. This can lead to some great character interactions. Characters from Naruto may be confused by the digital concepts at first, but then they adapt in unique ways.
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 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.
The unique combination of two very different fictional universes. Smallville has a more down - to - earth, small - town feel with its own set of superpowered characters, while the Avengers are a big - city, global - scale superhero team. When they cross over, it creates new and unexpected storylines.
