Black Widow and Hawkeye can also be significant characters in this type of fanfiction. Black Widow's skills in espionage and dealing with people could be useful in understanding the feral child. Hawkeye's down - to - earth nature might make him more approachable for the child. And if there are any other characters from the Marvel universe that are related to the Avengers, like Nick Fury, they can also be part of the story.
Obviously, the Avengers are main characters. This includes Iron Man, Captain America, Thor and others. They are the ones who usually find the feral child and get involved in the child's story. The feral child themselves is also a main character. Their backstory, their powers or lack thereof, and their personality all play important roles in the fanfiction.
Obviously, Tony Stark himself is the central character as it's about his collapse. But other key characters usually include Pepper Potts, his love interest. She often plays a role in either trying to prevent the collapse or dealing with the aftermath. For example, in some fanfictions, she's the one who discovers him first.
Hermione Granger might also be a central character. Her thirst for knowledge could lead her into situations where she is in the dark, like exploring a new area of magic that has many unknowns. As a child in Hogwarts, she might be trying to solve a mystery that no one else has been able to, and she has to start from a place of not knowing much, or being 'in the dark' so to speak.
Often, Harry Potter himself might be involved. Since he was an orphan, he could be a key figure in understanding how child services work or how they could have been improved in his case. Hermione could also be involved as she is very much into social justice and would likely be interested in the well - being of children in the wizarding world. And there could be original characters created by the fanfiction author, like a dedicated child services worker who is trying to make a difference in the lives of magical children.
Alina is also frequently involved. Her connection to the Darkling in the original work makes her a natural addition in many fanfictions. Their complex relationship can be further explored or even rewritten in different ways in fanfiction.
One interesting 'Avengers Feral Child Fanfiction' story could be about a feral child with superpowers being discovered by the Avengers. The child might have unique abilities that are both a mystery and a potential asset to the team. For example, they could have an uncanny sense of danger or be able to communicate with animals in a way that helps the Avengers during a mission.
Naruto himself is often a central character in 'naruto destruction fanfiction'. Since he is the main protagonist of the original series, fanfiction writers like to put him in situations where he has to deal with destruction. Sasuke is also frequently involved as his rival, and their relationship can be explored in the context of destruction, like if they have to work together to stop a greater threat of destruction.
Obi - Wan Kenobi is frequently in Anakin Snaps fanfiction. As Anakin's master, he has a big role to play. Their relationship is often explored, and Obi - Wan's reactions to Anakin's snapping are crucial. Sometimes he tries to bring Anakin back from the brink, while other times he might be the cause, albeit unintentionally, of Anakin's breakdown.
Well, Naruto is obviously a main character in most of these. But there could also be Sasuke. He might be either an ally or an adversary in relation to the dagger. For example, if the dagger has a power that can either be used for good or evil, Sasuke could be tempted by its darker potential.
There can be original characters created specifically for the fanfiction. For instance, a detective who is obsessed with bringing down the Joker but slowly starts to lose his own sanity in the process. This character can provide a new perspective on the Joker's reign of terror.
Obviously, the Reaper is a main character. Ruby Rose is also often involved as she is one of the central characters in RWBY and her connection to the concept of death (which the Reaper represents in a way) makes for interesting interactions. Weiss Schnee can also be seen in some fanfictions, as her family's past and her own story can cross paths with the Reaper's storyline in creative ways.
