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.
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.
One idea could be that the descendants' magic somehow gets intertwined with the Avengers' technology. For example, Mal's spell - casting could start affecting Iron Man's suit, causing glitches and unexpected behaviors. This would force the two groups to work together to figure out how to separate the magic from the tech.
One idea could be that Godzilla is drawn to the energy source of one of the Avengers' tech, like Stark's Arc Reactor. This causes chaos as Godzilla approaches the city where the Avengers are based. The Avengers initially see Godzilla as a threat and try to fight it. But then they realize that an even bigger alien force is using Godzilla's presence as a distraction. So, they have to find a way to communicate with Godzilla and work together to defeat the common enemy.
One idea could be that Nightwing is transported to the Avengers' universe through some sort of interdimensional rift. He then has to team up with the Avengers to fight a common enemy, like Thanos who has somehow acquired some of Batman's tech. Nightwing's acrobatic skills and detective abilities would be a great addition to the Avengers' power set.
Power struggle is also prevalent. The characters from Descendants, who are often the offspring of famous Disney villains and heroes, have their own power dynamics. When Maleficent enters their world, there is a new level of power struggle as she is a powerful force herself. This can lead to interesting plotlines where they have to either compete or cooperate.
I think Loki and Mal would make a very interesting pairing. Loki is known for his trickery and Mal has her own devious side. They could either be at odds, constantly trying to out - scheme each other, or they could team up for some self - serving purpose. Their combined cunning could lead to some very unpredictable and exciting storylines.
I found a really fun crossover fanfic where the villains from Descendants team up with some of the forgotten villains from Once Upon a Time. It's called 'Villainous Alliances'. It shows how they would interact and form plans to take over both their worlds. The character development in this fanfic is quite good as it gives more depth to the Descendants' villains who might seem one - dimensional at first.
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.
There's 'Mixed Magics: Harry Potter and Descendants'. This fanfiction delves deep into how the two different magical systems would interact. For example, the use of magic wands in the Harry Potter world versus the natural magic the descendants seem to possess. The plot often revolves around a threat that can only be defeated by combining the powers and knowledge from both universes.
