Another aspect could be the relationship between Black Widow and Hawkeye as parents. Since they both have had difficult pasts, they could be either overprotective or determined to give the baby a normal life.

Perhaps a storyline where the baby is raised in secrecy. Hawkeye and Black Widow are constantly on the run to keep the baby safe from their enemies.

It could also involve the baby having to face some internal conflict, being half - Hawkeye and half - Black Widow in terms of abilities and personality.
A great Hawkeye and Black Widow fanfiction could involve a scenario where they go undercover as a couple. They would have to pretend to be in love while still maintaining their professional relationship.

There could also be fanfictions that explore their relationship in an alternate universe where they are the last remaining Avengers and have to rebuild the world together.

Thor could also be a part of the story, perhaps using his godly powers to shield the baby from threats.
One interesting storyline could be Hawkeye and Black Widow on a mission before they joined the Avengers.

One idea could be a pre - Avengers story where Hawkeye and Black Widow are on a mission together in a foreign country.

Another plot could be a post - Avengers story where they are trying to deal with the aftermath of a big battle. Maybe they are helping civilians and at the same time, they start to realize their feelings for each other more deeply. A third plot could be a story set in an alternate universe where they are the leaders of the Avengers and have to make tough decisions about how to protect the world from a new threat that is far more powerful than any they've faced before.
One idea could be the unique powers or abilities the baby might inherit. Maybe the baby has Captain America's super strength and Black Widow's agility and combat skills.

In this Budapest - set fanfiction, Hawkeye and Black Widow could be on a rescue mission. A fellow agent has been kidnapped and is being held in Budapest.

Their relationship could be developed through shared danger. For example, if they were trapped in a collapsing building during a mission in Budapest, they would have to rely on each other to survive. This would strengthen their bond of trust.
