Power is a common theme. Xehanort is often a power - hungry character, and in crossovers, his pursuit of power is pitted against the powers and rules of the new universe he enters. For example, if he crosses over into a universe with a strict moral code regarding magic use, his power - hungry ways will be challenged.
Redemption can also be a theme. Some fanfictions explore the possibility of Xehanort finding redemption in a new world. Maybe in a world full of kindness and forgiveness, he starts to question his dark past and actions. This often involves complex character development as he struggles between his old self and the new influence of the crossover world.
Conflict is always there. It could be a conflict between Xehanort and the heroes of the crossover world. Or it could be an internal conflict within Xehanort himself as he tries to adapt to the new world while still holding onto his original goals. This conflict drives the plot forward and makes for an interesting read.
There's also 'Xehanort's Journey through Kingdom Hearts Crossovers'. This fanfiction takes Xehanort on adventures across different Kingdom Hearts - like worlds that have been cross - overed with other game universes. It's interesting to see how Xehanort's dark plans are affected by the new environments and characters he encounters.
One common theme is adventure. Since the Valerian universe is full of exciting and unknown elements, when crossed with other universes, it often leads to epic adventures. For example, a crossover with a space - opera like Star Trek could result in a story where Valerian and his companions explore new galaxies together with the Star Trek crew.
One common theme is the clash of different powers. For example, when the Incredibles cross with other superhero groups, there's always the exploration of how their powers compare and contrast.
Power struggle is a common theme. Starscream is often power - hungry in the original Transformers series, and in crossovers, this trait is magnified when he enters new universes with different power hierarchies. For example, in a crossover with the Lord of the Rings, he might try to claim the One Ring to gain ultimate power.
The theme of adaptation is quite prevalent. Asriel has to adapt to different cultures, technologies, and ways of life in the crossovers. For instance, if he enters a cyberpunk - themed world, he has to get used to the high - tech environment and the different social structures. Another common theme is the exploration of good and evil. When he crosses over to a world like the Lord of the Rings, he has to decide which side he's on and how to fight against the forces of evil in that world. This exploration of moral concepts is an important part of many Asriel crossover fanfictions.
A common theme is the clash of different assassin cultures. For example, when Hitman crosses with other assassin - themed franchises, their methods of killing, their code of ethics, and their loyalty to their respective organizations are often compared and contrasted.
One common theme is the exploration of power dynamics. When the X - Men cross over with other groups, like the Avengers or the Fantastic Four, there's always a comparison and contrast of their powers. For example, in a crossover with the Avengers, the mutants' powers might be seen as more unpredictable compared to the technology - based powers of some Avengers.
One common theme is power struggle. Since Shego has her own set of powers, when she crosses over into other universes, there's often a conflict or comparison of powers. For example, in a crossover with the Powerpuff Girls universe, her powers are pitted against the superpowers of the girls. Another theme is the exploration of her character. Writers often use crossovers to show different sides of Shego, like her potential for redemption or her adaptability in new situations.
One common theme is the clash of different investigative styles. For example, when a character from 'The Mentalist' crosses over with a detective from another show, their methods of solving crimes might be very different. Another theme is the exploration of new worlds. If it's a crossover with a science - fiction or fantasy show, the mentalist character has to adapt to a whole new set of rules and environments.
Love and relationships can be a theme as well. When Eiken characters cross over with characters from other shows, there can be new romantic interests or complex relationship dynamics. Sometimes it's a simple crush, and other times it can be a more in - depth exploration of how different personalities interact in a romantic context.
