One common theme is grief. The widow is dealing with the loss of her husband, and this emotion often pervades the story. It can be shown through her memories or her moments of solitude.
Another theme is independence. After being part of a couple, she has to learn to stand on her own feet. This could involve managing finances, making decisions alone, and taking care of the household all by herself. For example, she might have to figure out how to fix a leaky roof or deal with a difficult landlord.
Friendship is a common theme. For example, like in stories where a kid makes a new friend, either an animal or another child. Another common theme is adventure. Kids often go on little adventures in these stories, exploring new places or solving small mysteries.
One common theme is growth. For example, a little boy might start off as timid but through various experiences, like facing a bully or helping a neighbor, he becomes brave and more self - assured. Another theme is discovery. The boy could discover a new place in the woods near his home or find a hidden talent within himself, like being good at music or storytelling.
One common theme is revenge. As the name 'black widow' implies, like the spider that kills its mate, the bride in the story often seeks revenge, perhaps for a broken heart or betrayal.
Growth is a common theme. Like in many stories where a little boy starts as naive and through experiences becomes wiser.
Another theme could be redemption. Often, these kids start off bad but then through some event or self - reflection, they try to become better. For example, they might realize that their actions are hurting others and decide to change for the better. This shows that people can grow and improve even if they start off on the wrong foot. Also, family or friendship can be a theme. Sometimes it's the influence of parents or the loss of a friend due to bad behavior that prompts the change in the bad little kid.
Survival is also a common theme. Given her dangerous life, fanfics often show how she manages to survive in difficult situations. Her identity is another theme. Writers like to play with the idea of her true identity, whether it's the Natasha Romanoff we know or if there's more to her. And loyalty, whether it's to her friends, her cause, or her own sense of right and wrong.
One common theme is redemption. Since Natasha has a dark past, many fanfictions explore her journey towards making up for the things she's done. For example, she might try to save people she once targeted.
One common theme is mischief. Little Johnny often gets into little acts of mischief, like trying to play pranks on his siblings or friends, which makes the stories humorous.
One common theme is redemption. The characters often have to overcome past mistakes or regrets. For example, the widow may feel guilty for falling in love with her husband's brother, and the brother may have to redeem himself for having feelings for his brother's wife. Another theme is family acceptance. Since their relationship is a bit unconventional, they usually face resistance from family members, and the story often focuses on how they gain that acceptance.
The theme of self - discovery also pops up. Black Widow, coming from a world of espionage, might find new aspects of herself in Naruto's world full of chakra and ninja clans. And Naruto could also learn new ways of thinking from Black Widow. These fanfictions often show how they grow as individuals through their interactions.
