Alliance building is also common. For instance, in a crossover with 'Star Trek', the Helldivers, who are used to a more militaristic approach, have to learn to cooperate with the United Federation of Planets. This involves diplomatic efforts as well as military coordination, and often leads to character development as they learn from each other's values and ways of life.
Survival against overwhelming odds is another theme. In a crossover with 'Dead Space', the Helldivers have to face the terrifying necromorphs. This theme is exciting as it shows how the Helldivers' training and equipment are tested in a completely different and horrifying scenario. They have to adapt their combat styles and use their resources cleverly to survive.
There's also a Helldivers crossover with 'Mass Effect'. This fanfic often explores how the Helldivers would interact with the different alien species in the Mass Effect universe. It might involve them joining forces to fight a common enemy, or having misunderstandings due to their very different cultures and ways of war.
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.
