His physical abilities would likely be above average, with great endurance and speed, similar to his parents. And perhaps he has a special mental connection to his parents' memories or knowledge, which helps him in difficult situations.
Since Black Widow has a lot of experience with different types of weapons, Stiles might inherit an aptitude for weaponry. He could be a natural at using guns, knives, and other gadgets.

One possible storyline could be that their son inherits their skills. He might have Captain America's super strength and leadership qualities, combined with Black Widow's stealth and espionage skills.

They solve crimes that are related to super - powered individuals, using their own unique abilities and intelligence.
In fanfiction, their son could be a powerful and complex character. Maybe he inherits Black Widow's combat skills and strategic mind, along with Captain America's sense of justice and leadership.

For example, when the child wants to join a mission too early, they have to work out how to handle it as a couple.
