Yes, there are likely many. You can start by looking on popular fanfiction websites like Fanfiction.net or Archive of Our Own. On these platforms, you can filter out the inappropriate content and search specifically for crossovers between 'Harry Potter' and 'Black Widow' that focus on adventure, friendship, or other non - 'lemon' themes.
Well, one idea could be the contrast in their worlds. Harry Potter is from a magical world full of wizards and spells, while Black Widow is from a more modern, non - magical spy - like world. Maybe in the fanfiction, they meet through some sort of magical - technological mishap and have to team up. They could learn from each other's skills, like Harry teaching her some basic defensive magic and Black Widow showing him how to be more stealthy in a non - magical way.
Perhaps a story where Black Widow accidentally stumbles into the wizarding world and is mistaken for a threat at first. But then she proves herself useful in helping to solve a mystery within Hogwarts, like a series of strange disappearances that are actually related to a dark plot. This would be a story full of mystery, adventure, and no 'lemon' content.
It could use a portal or some sort of magic - tech device. For example, a magical experiment in the Harry Potter world goes wrong and creates a portal to the Marvel universe where Black Widow is. Or maybe a Stark Industries experiment accidentally taps into the magic of the Harry Potter world. This would be a simple and straightforward way to bring the two together.
One unique element is the combination of magic and spy skills. Black Widow's combat and espionage abilities blend with the magical spells and potions in the Harry Potter universe. For example, in some fics, she might use her martial arts skills in a wizarding duel.
In a fanfiction, the Avengers could be called to the Harry Potter universe to help fight Voldemort. Black Widow would be a key player in infiltrating Death Eater strongholds. She could teach the Order of the Phoenix some of her combat and espionage techniques. And perhaps Harry Potter could gain some inspiration from the Avengers' teamwork and use it against Voldemort.
She could be a protector. Given her combat skills, she might safeguard the students at Hogwarts from external threats, like dark wizards or creatures. For example, when Death Eaters attack, she could use her martial arts and weaponry skills to fight them off.
Well, in a 'Harry Potter raised by Black Widow' fanfiction, the whole Hogwarts experience might be different. Black Widow would likely be very protective of Harry and might even try to teach him some of her spy - like skills. For example, she could show him how to gather information secretly or how to blend into a crowd unnoticed. And Harry's view on magic might also be influenced by Black Widow's more practical and survival - based mindset.
One possible plot could be that Harry Potter, as the son of Black Widow, discovers his mother's secret past in the wizarding world. He might inherit some of her unique skills, like her combat abilities, and use them to face new threats in Hogwarts. Maybe he forms a special group of friends who are intrigued by his strange heritage and they all embark on adventures together.
One common theme is the clash of different worlds. Harry Potter's magical world and Black Widow's more spy - thriller world are so different, and exploring how they interact is popular.
