Character development is crucial. Each character from both universes should have their own arc in the fanfiction. Let's say Scarlett from Gi Joe. At first, she might be skeptical about the Transformers' ability to work as a team since they seem so different from humans. But as she gets to know them better, she realizes they have their own code of honor. And for a Transformer like Megatron, his encounter with the Gi Joe team could make him more determined to conquer not just Cybertron but also Earth, seeing the Joes as a new threat. This way, the characters' growth is tied to the crossover and makes the blend of the two worlds more believable.
Blending the cultures of the two is also important. The military - style discipline of the Gi Joe team can contrast and complement the more mechanical and alien culture of the Transformers. You could have scenes where the Joes are amazed by the Transformers' technology, and the Transformers are intrigued by the Joes' human - like emotions and loyalty. For example, a Transformer might not understand why the Joes risk their lives for their comrades, but as they work together, they come to respect this human trait. Also, in terms of the story's setting, you can have parts of the story take place on Earth in military bases and other parts on Cybertron among the giant robotic structures.
The key is to find common ground. Both have their own groups of heroes and villains. You can start by having a threat that affects both universes. For instance, a new evil force that wants to take over both Earth (where the Joes operate) and Cybertron (the Transformers' home). This forces the two groups to collaborate.
To blend the worlds well, you need to consider the characters' personalities. The serious and scientific minds of the Criminal Minds team can contrast with the more laid - back and supernaturally - aware Buffy gang. This contrast can create interesting interactions and conflicts. For example, some of the BAU members might be skeptical about the existence of vampires at first. Then, as they witness it, they have to adapt their worldviews. You can also introduce a common enemy that requires both groups to work together. Maybe a demon that is using psychological manipulation to create chaos in both the human world and the Buffyverse.
Another interesting concept is a character - based crossover. A Joe like Snake Eyes could form an unlikely bond with a Transformer like Bumblebee. Snake Eyes' ninja skills could be used in combination with Bumblebee's speed and agility in combat. They might start off not trusting each other but gradually learn to work together as they face various threats.
The blending can start with a crossover of characters. For instance, Percy could meet Yugi at a special event that bridges the two universes, like a magical tournament that exists in both worlds. Then, they could exchange their skills and knowledge. Percy could show Yugi how to fight physically in a more demigod - like way, and Yugi could teach Percy about the strategies of Yu - Gi - Oh dueling.
To blend the worlds well, you can start with the geography. Imagine if the Viking lands were somehow connected to Westeros, perhaps through a long - forgotten sea route. Characters could then travel between the two places, bringing their cultures and ideas with them. Also, consider the religions. The Norse gods in Vikings and the Seven in Game of Thrones (or the old gods in the North) could have some sort of interaction. For instance, a Viking character could be confused by the different religious beliefs in Westeros and try to impose their own, leading to interesting conflicts and discussions.
Well, a good way is through the use of magic or energy. In Naruto, there's chakra, and in Star Fox, there's energy sources for their ships and weapons. Writers can make it so that these two forms of power interact in interesting ways, like chakra - powered ships or energy - enhanced jutsu.
Character relationships are also key. You could have Naruto befriend a Sekirei who is out of place in the ninja world. Their friendship could grow as they help each other understand their respective worlds. This would allow for a lot of emotional depth and character growth in the story. You could also introduce conflicts based on the differences in their worlds' values. For instance, the ninja's code of loyalty might clash with the Sekirei's concept of their purpose. Resolving these conflicts can make the fanfic more engaging.
You can blend the two worlds by having characters from each world interact. For example, the ninjas of Naruto could meet the Berserkers. They might initially be at odds, but then find common ground in their fighting skills. The ninjas' use of chakra and jutsu could be compared and contrasted with the Berserkers' brute strength and rage - based powers.
Well, the first step is to find common elements. For example, both Naruto and 2NE1 have a sense of teamwork. In Naruto, the characters rely on each other in battles, and in 2NE1, the members work together to create great music and performances. In a fanfiction, this could be emphasized by having the Naruto characters and 2NE1 members collaborate on a project that requires both physical strength and musical talent.
In a Naruto Date A Live crossover fanfiction, the settings can be merged. Imagine the Hidden Leaf Village coexisting with the world of Date A Live. The villagers might have to deal with the appearance of Spirits. And the Spirits could be intrigued by the ninja way of life. The cultural differences between the two worlds would also add depth to the story. For instance, the Spirits might not understand the concept of chakra at first, but as the story progresses, they could start to learn and use it in their own ways.
The worlds can be blended by introducing Gundam technology into RWBY. For instance, RWBY's Beacon Academy could start a new program to train students in Gundam piloting. Or, the Grimm could be a threat to the Gundam universes as well, leading to a united front between RWBY and Gundam forces.
