Another challenge is pleasing the fans of both franchises. Fans of 'parasyte' and the other series you're crossing it with will have certain expectations. If you deviate too much from what they know and love, they might not like the fanfic. So, you have to balance innovation with staying true to the source materials.
A great 'parasyte crossover fanfic' is the one that crosses it with the 'Tokyo Ghoul' universe. Since both deal with the idea of beings that are not quite human and the struggle for co - existence, it makes for a very engaging read. The different powers and characteristics of the characters from both series interact in really unexpected ways.
The plot might focus on the struggle for identity that both Kaneki and Shinichi face. Kaneki is caught between his human and ghoul sides, while Shinichi has to deal with having a parasite in him. In the crossover fanfic, they could exchange their experiences and learn from each other. They might also encounter a new type of being that combines the traits of ghouls and parasites, which forces them to re - evaluate their own identities and how they fit into this new world of the crossover.
Kaneki's kagune could be used in combination with Shinichi's parasite - enhanced physical abilities. For example, Kaneki could use his kagune to create a distraction while Shinichi uses his speed and strength to attack the enemy. Or they could work together in a more direct way, with Shinichi using his parasite - hand to hold an enemy in place while Kaneki delivers a powerful kagune strike.
Sure. 'Parasyte' crossovers can be really interesting. One great one might be a 'Parasyte' and 'Attack on Titan' crossover fanfiction where the parasites have to deal with the Titans. It creates a whole new level of chaos and survival scenarios.
The moral and ethical dilemmas are often great plot elements. When two different universes collide in a crossover, characters from different moral backgrounds have to interact. In a 'Parasyte' and 'Star Trek' crossover, the Federation's values would be put to the test when dealing with the parasitic nature of the 'Parasyte' entities.
The plot could involve a shared threat that forces the Tokyo Ghoul and Parasyte universes to collide. Maybe a new type of organism emerges that is even more dangerous than ghouls or parasites. The characters would then have to combine their unique abilities to combat this threat. For instance, Kaneki's kagune and Shinichi's enhanced physical abilities with his parasite Migi could be used in tandem. This would create an interesting dynamic as they try to figure out how to work together while also dealing with their own internal struggles related to their inhuman natures.
If we consider other characters, like Touka from Tokyo Ghoul, her combat skills combined with a parasite - like ability could be really interesting. Imagine if she had some of the regenerative abilities of a parasite. She could take more risks in battles. And for the parasites in Parasyte, if they could somehow access the kagune - like substances from ghouls, it might give them an entirely new form of attack or defense. They could potentially use it to create barriers or projectiles similar to how ghouls use their kagune.
Well, in the 'Parasyte Light Novel', the main character has a parasite in his hand. This sets up a very strange co - existence situation. There are battles against other parasites who have more malicious intents. It shows how the main character struggles with his new - found situation, his changing perception of the world around him, and also his fight for survival in a world where humans are being hunted by these parasites. It's really a thrilling and thought - provoking story.
