To make it more emotional, focus on Edward's internal thoughts and feelings. Let the readers know how much he's losing. You can also add flashbacks of their relationship, showing how far they've come and how much they mean to each other. When Bella dies in his arms, his grief and the memories that flood his mind will tug at the readers' heartstrings. For instance, if you describe how Edward is thinking about all the future plans they had together that will now never come to fruition, it makes the situation more poignant.
One way to make the 'Bella dies in Edward's arms' fanfiction more emotional is through the use of music or song references. If there are certain songs that are associated with their relationship in the fanfiction, and as Bella is dying in Edward's arms, he might be thinking about those songs. Also, the dialogue between them at the moment of death can be very powerful. Bella could say things like 'I'll always be with you' or Edward could be whispering his love for her over and over again. Additionally, the setting can play a role. If it's a place full of their memories, like the meadow where they often met, it adds to the emotional depth.
In certain 'Bella dies in Edward's arms' fanfictions, it might be related to time - travel elements. Imagine a situation where Bella travels back in time to change something for the better in Edward's past, but in doing so, she disrupts the timeline in a way that causes her own death. When she returns to the present (or what was the present before the time - travel), she is already dying and Edward holds her as she passes away. Another idea could be that Bella's human frailty, combined with the dangerous vampire world she's a part of, leads to her being in a situation where she can't be saved, and Edward has to watch her die in his arms.
You could make their relationship more unique by having them communicate in a different way. For example, instead of just talking, they can have a mental connection from the start that only they can understand. This would make their bond more special and exclusive.
Well, one way to make it emotional is to have a slow - build - up to Tails' death. Start with him being full of life and having big dreams. Then, as the danger approaches, show his fear and determination. You can also add flashbacks of his happiest moments with his friends. For instance, when he first met Sonic or when they had a big victory together. When he finally dies, have his friends find something that was very precious to him, like a handmade gift for Sonic. This would really tug at the heartstrings. Additionally, you could have a scene where Tails says goodbye to each of his friends individually, with heartfelt words that show how much he cares about them.
One way is to focus on their platonic love. Emphasize the deep friendship and respect they have for each other. For example, write about them having long conversations about their hopes and dreams, or how they support each other through difficult times.
Bella might go into a deep depression. She was so in love with Edward, and his death could shatter her world. She could become withdrawn and isolate herself from her friends and family.
One emotional moment could be Thor's reaction. He might be filled with grief, disbelief, and a sense of helplessness. His usually strong and mighty self is shattered as he holds Loki in his arms. Another moment could be Loki's final words, if there are any in the fanfiction. His words might be a confession of his true feelings towards Thor, perhaps regret for past actions or simply an expression of love for his brother. It could also be the moment when other characters, like the Asgardians, learn of Loki's death. They may have mixed feelings considering Loki's complex past, but still, his death would be a significant event that shakes the Asgardian community.
Anakin would be completely shattered. Ahsoka was one of the few people he truly cared about deeply. Her death in his arms would make him question his abilities as a Jedi and a protector. He might feel a deep sense of rage towards whatever or whoever caused her death, which could start to cloud his judgment and lead him down a darker path.
Bella would likely be very frightened during the car incident. Once Edward saves her, she'd be extremely relieved and probably feel even more attached to him. Edward, on the other hand, would be initially worried and focused on getting Bella to safety. After saving her, he might feel a sense of relief as well, but also a bit of that over - protective feeling that he often has for Bella.
One emotional moment could be Sasuke's realization of losing Sakura. His usually stoic facade might crumble as he holds her lifeless body, perhaps reminiscing about all their shared moments, from their early days as teammates to the more complex relationship they developed over time.
