Give your characters clear motives. In the aftermath of a civil war, a character might be motivated by revenge, or by the desire to rebuild their family's lost fortune. By having a well - defined motive, the character becomes more believable. Also, let them have flaws. No one is perfect, and in a post - civil - war setting, flaws can be magnified. Maybe a character is too trusting or too quick to anger, and these flaws can lead to interesting plot developments.
To create a believable OC for this fanfiction, start with their personality. They should have flaws and strengths. For instance, they could be brave but also impulsive. Their appearance can also say a lot about them. If they are from a poor background, their clothes might be shabby. Their relationships are important too. They might have a best friend who is also involved in the civil war in some way. Also, think about their role in the story. Are they a fighter, a healer, or a strategist? This will help them fit into the complex world of 'Captain America Civil War' more realistically.
One type of typical character is the healer. In the post - civil war setting, there is a great need for physical and mental healing, and these characters, be they doctors or just kind - hearted individuals, help the wounded and traumatized. Another is the opportunist. These characters see the post - war chaos as a chance to gain power or wealth, often at the expense of others. And there are the refugees. People who were displaced during the civil war and are now searching for a new place to call home in the aftermath, facing many challenges along the way.
Give them flaws. In war, no one is perfect. A character could be overly confident which leads to mistakes, or be too scared which affects their performance. Their flaws can drive the story and make them more relatable. For instance, a soldier who freezes in the heat of battle because of a childhood trauma. You can also show their growth throughout the story as they face the harsh realities of war.
Steve Rogers and Tony Stark are surely among the most common. Since they were at the center of the conflict in the movie, their post - war stories are often explored. Whether it's them dealing with the emotional fallout or trying to fix what they broke.
Believable characters in this fanfiction can be created by making them react realistically to the events of the Infinity War. If they see destruction and death, they should show emotions like shock, grief, or anger. Also, their powers should have limitations. No one should be all - powerful without some sort of drawback. For instance, a character with super strength might get tired quickly if they overexert themselves. This makes them more human - like and believable in the extreme situation of the Infinity War.
Well, you could also have a plot where the secrets that were buried during the civil war start to surface in the aftermath. Maybe there were hidden alliances or betrayals that now come to light and create new tensions. It could involve characters having to deal with the truth about their past actions or the actions of their loved ones.
For human characters, draw on real - life military and civilian archetypes. For example, a battle - hardened marine could be modeled after soldiers you see in documentaries. Give them a backstory, like they joined the military to support their family. For Batarian characters, study their in - game lore. Maybe a Batarian trader who gets caught in the crossfire of the war. Their motivation could be to protect their business and family.
You could also rewrite the Sokovia Accords in a more favorable light. Instead of it being a source of division, make it something that the heroes can work with. Maybe add some clauses that protect the heroes' rights while still allowing for some form of government oversight. This would satisfy both sides, like Steve's side who were worried about freedom and Tony's side who wanted some accountability.
Study the original characters first. Notice their traits, quirks, and backstories. Then, for your own characters in the fanfiction, give them a clear motivation. It could be power, revenge, or protecting someone. Also, give them flaws. A character without flaws is not believable. For example, a character could be too impulsive which gets them into trouble.
Study the existing characters first. Notice their mannerisms, speech patterns, and relationships. For example, Wanda is often strong - willed but also has a vulnerable side. Replicate these traits in your new characters. If you create a new neighbor, maybe they have a similar duality, like being overly friendly on the surface but hiding a secret.
