In a crossover, the relationships would be a complex mix. Consider a 'Twilight' werewolf in the 'Heroes' world. They might find kinship with characters who have animal - like powers. But at the same time, their territorial nature could cause conflicts. On the other side, if a 'Heroes' character with healing powers went to the 'Twilight' world, they could potentially change the fate of some characters. This would have a huge impact on the relationships within the 'Twilight' universe, especially for those whose lives are in danger, like some of the human characters in the vampire - werewolf conflict.
If there was a crossover with the Spider - Man universe. Peter Parker would be in awe of Wanda's powers. He would probably try to ask her a million questions. This could make Vision a bit jealous as he sees Peter as a bit of a pest. Meanwhile, Aunt May would probably invite Wanda and Vision over for dinner, and in that domestic setting, we would see a whole new side of their relationships. Wanda might start to see Vision in a more human way as she observes the relationship between Peter and Aunt May.
If we think about the relationships in a Bleach and Highschool DxD crossover. The devils in Highschool DxD are used to a certain hierarchy and power play. When they meet the Soul Reapers, who also have a strict hierarchy, there could be clashes. For instance, Rias and Byakuya might initially have a tense relationship. Rias is used to being in charge in her own way, and Byakuya is a proud captain. But as they see each other's sense of justice and the need to protect their respective worlds, they could start to work together. And for the students in Highschool DxD, they might look up to the more experienced Soul Reapers. The Soul Reapers, in turn, might be amused by the more carefree and hormonal nature of the Highschool DxD students. This could lead to a mentoring - like relationship in some cases.
If Ben entered the Attack on Titan world, his relationships would be complex. He might initially be seen as a threat, but as he uses his powers to help, he'd gain allies. His relationship with Eren could be one of mutual respect as they both have powers to fight. Eren might be in awe of Ben's ability to transform into different forms.
In a crossover, Archie's relationship with his friends might change. He's used to being the football star in Riverdale, but in the Arrowverse, he could be in awe of the superheroes. His friendship with Jughead might be tested as Jughead tries to keep Archie grounded while Archie is excited about the new world. Betty and Veronica's relationship could also shift. They might compete in a different way, like trying to impress a certain Arrowverse hero. Their friendship could become more competitive or they could find new common ground in helping the heroes.
The relationships would change drastically. Naruto, known for his positive and friendly nature, would likely try to befriend many Bleach characters. For example, he might form a close bond with Ichigo as they both have a strong sense of justice. However, some characters from Bleach might be initially suspicious of Naruto's strange powers. In the same vein, Bleach characters might introduce Naruto to new concepts like the importance of reiatsu, which could change how he views power. And relationships within each universe might also shift as characters from one series interact with those from the other.
The relationship between C.C. and Rukia would be quite complex. C.C. has a very mysterious and detached personality, while Rukia is more duty - bound and has a strong sense of camaraderie. They could start off as rivals, both being strong female characters with unique powers. However, as they get to know each other's pasts and motives, they might develop a grudging respect. C.C. might be intrigued by Rukia's connection to the Soul Society, and Rukia could be curious about C.C.'s immortality and her role in Lelouch's life.
On the other hand, it could cause some tension. If a fanfiction misrepresents a particular relationship within the Cullen family, it could lead to some arguments or misunderstandings among them. For instance, if a fanfiction wrongly depicts the relationship between Edward and Bella in a way that the other Cullens find inappropriate or inaccurate.
If they read positive fanfiction about their relationships, it could strengthen their bonds. For instance, if the fanfiction emphasizes the love between Edward and Bella in a beautiful way, they might feel a deeper connection to each other.
The relationship between Naruto and Lavi would be quite fun. Lavi is a bit of a joker and Naruto's positive attitude would match well with him. They could team up and get into all sorts of adventures. Hinata might be a bit shy around some of the D Gray - Man characters at first, but she would gradually open up. The relationship between the Akatsuki and the Akuma would be very different. The Akatsuki are more about power and their own goals, while the Akuma are mindless servants of the Millennium Earl. However, some members of the Akatsuki might see the potential in using Akuma for their own ends, which would create a very dangerous situation for both worlds.
In a crossover with One Piece, Naruto's muteness would change his relationship with Luffy. Luffy might be initially confused but would quickly adapt and start communicating in his own unique way with Naruto. Their bond would be more about shared adventures and understanding through actions rather than words.
