In a 'Harry Potter marries Zatanna' fanfiction, it could start with Zatanna being summoned to Hogwarts for some reason, like to help with a particularly stubborn dark magic problem. Harry is assigned to assist her. They find themselves constantly in each other's company. Zatanna's flamboyant and performative magic fascinates Harry, while Harry's steadfast and selfless nature draws Zatanna to him. As they work together more, they realize they have feelings for each other. Their relationship progresses, and after many adventures and facing challenges together, they get married, creating a new chapter in both the wizarding world and Zatanna's world of magic.
Well, in this fanfiction, perhaps Zatanna is on a mission in the wizarding world. She crosses paths with Harry Potter. Harry is intrigued by her unique brand of magic which is so different from his own. They start to exchange knowledge about magic. This interaction leads to a deep friendship that gradually turns into love. They might face opposition from some in both their worlds who don't understand their union. But they overcome it all and get married, uniting their magical heritages.
One possible plot could be that a magical accident or a powerful spell gone wrong transports Harry Potter to Zatanna's universe. They meet and initially have misunderstandings due to their different magical upbringings. But as they get to know each other, they discover that they share a common goal of protecting the innocent. Their relationship develops as they fight side by side against dark forces that threaten both their worlds, and eventually they fall in love and decide to get married.
Well, perhaps Zatanna could use her magic to protect Harry from the Dursleys. She might teach him her unique brand of magic early on, which could give him an edge in the wizarding world. He could grow up learning both Zatanna's style of magic and the traditional Hogwarts magic, making him an even more powerful wizard.
One challenge could be cultural differences. Harry is from a world where magic is more about spells and potions, while Zatanna's magic is more about incantations and showmanship. Another challenge might be the acceptance of their relationship by their respective communities. Some in the wizarding world might think Zatanna's magic is too different and unorthodox, and some in Zatanna's world might not understand the ways of the wizarding world. Also, they might face villains who target them because of their combined power and the threat they pose to the status quo.
One possible plot could be that Zatanna adopts Harry after she has a premonition about his importance in the fight against dark magic. She raises him in a world that combines the magic of the DC universe (where she's from) and the wizarding world of Harry Potter. Harry would learn to use a wand as well as some of Zatanna's signature magic tricks. When Voldemort resurfaces, Harry has not only the knowledge of Hogwarts magic but also the power of Zatanna's magic, which could include things like mind - reading spells and the ability to create illusions on a large scale, which gives him an advantage in the battle against the Dark Lord.
A 'Harry Potter marries Supergirl' fanfiction might start with Supergirl accidentally landing in the wizarding world. Harry Potter, being the curious and brave wizard he is, approaches her. At first, there are misunderstandings due to their different cultures and powers. But as they start to communicate and learn about each other's worlds, they realize they have a lot in common. They both fight for the good of their respective worlds. This mutual understanding leads to a deep friendship and later, love. Their marriage would be a grand event, attended by wizards, witches, superheroes, and supervillains (the ones who are allowed to come under a truce). It would symbolize the coming together of two very different yet equally amazing fictional universes.
One possible plot could be that after the war, Harry realizes his deep connection with Tonks as they both have lost loved ones and are trying to rebuild their lives. They start to spend more time together, and gradually their friendship turns into love. Eventually, they get married and face the challenges of the post - war wizarding world together.
One possibility could be that in an alternate magical universe, Harry Potter, after all his adventures at Hogwarts and defeating Voldemort, travels to a different realm where he meets a queen. Maybe the queen is facing some magical threats in her kingdom and Harry, with his powerful magic, offers to help. As they work together, they fall in love and decide to get married. Their union could then bring about a new era of peace and cooperation between the wizarding world and the queen's non - magical kingdom.
In the 'Harry Potter marries Blackfire' fanfiction, it could start with Harry being sent on a diplomatic mission to Blackfire's homeland. There, he meets her and is immediately drawn to her strength and intelligence. Blackfire, on the other hand, is initially skeptical of Harry but soon sees his true character. As they work together on some magical problem or task in her land, their relationship grows. Their marriage could then be a symbol of unity between the Hogwarts - associated wizarding world and Blackfire's people. It would also bring about changes in how wizards view different cultures and relationships, as Harry and Blackfire would strive to bridge the gaps between their two worlds.
Perhaps there's a prophecy that involves both of them. They are forced to work together to figure out what it means. Along the way, they discover they have a deep connection, not just because of the prophecy but also because of their shared values of courage and loyalty. This connection eventually leads to marriage.
In the fanfiction, it could start with Harry feeling a strange pull towards an ancient magic site. There he meets Hecate. Hecate is intrigued by Harry's unique magic, which has survived so many dark encounters. They begin to collaborate on magical research, and during this process, their relationship deepens into love. Their marriage unites the Hogwarts magic that Harry grew up with and the primordial magic of Hecate. This causes a stir in the wizarding world as many are both excited and fearful of the new power dynamics that will surely follow.
In this fanfiction, perhaps a dark force is threatening both the wizarding world and the mutant world. Harry Potter and Storm are chosen as representatives of their respective worlds to form an alliance. As they work together to defeat the evil, they develop feelings for each other. Their marriage could then be a symbol of the new - found unity between the two worlds, and they would use their combined powers to protect both their peoples.
