Ant - Man. He was on the anti - registration side but he has a whole life outside of being a superhero. In fanfiction, we could explore how his experiences in the Civil War affect his normal life, like his relationship with his daughter and his business. And how he uses his skills in unique ways to help the other anti - registration Avengers.
Tenten. She doesn't get much spotlight during the war. A fanfiction could explore her role in providing weapons and support from behind the scenes. Maybe she invents a new type of weapon that could turn the tide of a small battle.
Kiba and Akamaru. They don't often get the spotlight during the big events like the Fourth War. In a fanfiction, they could have a special mission during the war. Maybe they discover a new type of enemy that can only be detected by Akamaru's sense of smell, and they have to use their teamwork to defeat it.
Another plot could focus on individual characters' struggles post - Civil War. Like how Tony Stark tries to make amends with those he fought against while still dealing with his own guilt. Maybe he starts a project to help the victims of the Sokovia incident which was a big part of the rift between the Avengers.
Rock Lee is often overlooked in some of the larger war - time stories. His unique taijutsu skills could be really interesting to explore in the context of the Fourth Shinobi War. He could take on some really tough opponents and show off his growth.
Vision is a character that can be quite popular in this type of fanfiction. His unique abilities and his own thoughts on the Sokovia Accords can create interesting storylines with Spiderman. He can be a source of knowledge and power that Spiderman might look up to or have to oppose, depending on the plot of the fanfiction.
The main characters include Iron Man, who is often at the forefront of technological solutions and may be more open to new ways of preventing threats, even if they are controversial. Captain America, who represents the more traditional values of freedom and justice and would oppose any actions that could undermine those. And then there are characters like Black Widow, who is caught in the middle, having to choose a side based on her own moral compass and loyalty to her friends. There are also other heroes like Spider - Man, whose presence adds a new dynamic to the conflict as he tries to figure out where he stands in this civil war.
Some notable characters who died in the comic include a few minor heroes whose sacrifices added to the intensity of the story.
Definitely Tony Stark. He has always been a fan favorite, and after Infinity War, his guilt and determination to fix things are really interesting to write about. Another popular one is Nebula. Her backstory and her relationship with Thanos make her a complex character that can be explored a lot in fanfiction. And Scarlet Witch is also popular. Her power is so great, and in the post - Infinity War scenario, she could be a key player in either revenge or redemption stories.
Rock Lee is often overlooked compared to the main characters. A fanfiction could focus on his journey to become an even greater ninja without relying on ninjutsu. Another underrated character is Shino Aburame. His unique bug - related abilities could be explored more deeply in a fanfiction, like how he might use them in different and unexpected ways.
The neighbor who was briefly shown in the movie could be an interesting character to focus on. We didn't really get to know much about him, but fanfiction could explore his story, like how he managed to survive on his own for so long. Maybe he had some unique skills or knowledge that helped him. Another could be the old man who we saw at the beginning. What was his life like before the invasion? Fanfiction could give him a more detailed backstory.
