One plot that stands out is when they are both trapped in a dimension that is a mix of Hogwarts and the prison planet from Riddick's world. They have to work together to find a way out. Along the way, they encounter strange creatures that are a blend of magical and alien species. Hermione uses her knowledge of magical creatures, and Riddick uses his combat skills to survive.
A creative plot could be where Hermione uses her magic to help Riddick control his 'Furyan' side better. For example, in some fanfics, she creates spells that can soothe his inner rage. This is interesting because it combines the magic system from Harry Potter with the unique biological aspect of Riddick.
In some fanfictions, the plot involves Hermione and Riddick being sent back in time. They end up in a pre - magical and pre - Furyan era. Here, they have to start from scratch and build a new society using Hermione's wisdom and Riddick's leadership skills. This plot is unique as it allows for a complete re - imagining of their characters in a different historical context.
A really creative plot is the one where Naruto and Tatsumaki are in a world where their powers are swapped. Naruto has to deal with Tatsumaki's psychic powers and her reputation in her world, while Tatsumaki has to figure out how to use chakra and live as a ninja. It's full of humorous moments as they struggle to adapt to their new powers, but also shows how they can grow and learn from each other's experiences.
A really creative plot is in a fanfic where the Leviathans can possess animals as well as humans. It makes for some really strange and unexpected encounters for Sam and Dean.
One creative plot is an orc - led environmental movement in fanfiction. Orcs, usually seen as war - like, are the protectors of nature. Another is orcs and humans swapping bodies and having to understand each other's cultures from a very different perspective. And the plot where orc tribes form a democratic society is also quite out - of - the - box.
A plot could be that Godzilla's DNA is used in some crazy experiment in the Naruto world and it creates a hybrid creature with ninja abilities. This new being has the strength of Godzilla and the stealth and jutsu skills of a ninja. It would be a very powerful and unpredictable character in the fanfiction.
One creative plot could be that Eevee is a reincarnation of a powerful ninja spirit. Naruto senses this and helps Eevee to unlock its hidden powers. This could involve training sequences where Naruto uses his own ninja training methods on Eevee.
There's a fanfiction where the Hogwarts houses are reimagined as different species from 'Ben 10'. So, Gryffindor might be like the Pyronites (the fire - based aliens in 'Ben 10'), known for their courage. Slytherin could be related to the Ectonurites (the ghost - like aliens), representing their sly nature. This reimagining creates a whole new dynamic within the Hogwarts world and also allows for some interesting interactions between the 'Ben 10' and 'Harry Potter' elements.
One of the most creative plots is in 'Naruto's Quantum Leap to Space'. Here, Naruto gets caught in a strange space - time rift that sends him hopping from one parallel universe in space to another. He meets different versions of his friends and enemies in these universes, and it really messes with his understanding of reality. Also, there are fanfictions like 'Naruto: The Space - Time Ninja' where Naruto discovers that the origin of ninjutsu is actually from an ancient alien civilization, and he travels through space to uncover more about this connection.
A creative plot could be that the villains from both universes team up. So, the Heartless along with some of Batman's classic foes like the Joker or Two - Face. The heroes from Kingdom Hearts and Batman would then have to combine their powers and skills to take them down. It would be a battle of different powers and ideologies.
Some fanfictions have Fem Sesshomaru and Inuyasha swapping powers. This creates a really interesting plot as they have to adapt to their new abilities while still being themselves. For example, Inuyasha with Sesshomaru's more refined and powerful abilities has to learn how to control them without losing his own brash nature. And Fem Sesshomaru with Inuyasha's powers has to deal with the more unruly aspects of his power.
Perhaps there's a fanfiction where the Human Torch has lost his powers and comes to the Naruto world seeking a way to get them back. Naruto, being the helpful hero he is, takes it upon himself to help the Human Torch. They go on a journey to find ancient scrolls or powerful sages who might be able to restore his powers. During this journey, they face many challenges and also learn from each other's fighting styles and strategies.
