It might involve a lot of world - building around the relationship. Since Merope Gaunt is from an old and rather dark wizarding family, there could be elements of her family's influence on their relationship. And for Harry, his more modern - day values might clash with the traditional ways of the Gaunt family.
Probably a rewrite of the entire 'Harry Potter' story. Harry marrying Merope would mean a completely different set of events leading up to it. Maybe it would start with Merope not dying after giving birth to Tom Riddle. And then she somehow meets Harry in a time - travel or alternate universe scenario. Their relationship would then be a mix of her ancient magic knowledge and his more heroic nature.
A 'Harry Potter Marries Merope Gaunt' fanfiction could explore the cultural differences between their generations. Merope comes from a much older time in the wizarding world. Harry would bring his own experiences from the modern wizarding world. The story could also deal with how the wizarding community would react to such an unexpected union. There could be a lot of drama and intrigue as they try to navigate their relationship in a world that might not accept them easily.
Yes, there are some out there. You can start by looking on fanfiction platforms like Archive of Our Own or FanFiction.net. However, keep in mind that the quality can vary greatly. Some might focus on exploring an alternate universe where this strange pairing occurs, delving into how their different backgrounds and magic would interact in a relationship.
One interesting plotline could be exploring Merope's life before she met Tom Riddle Sr. Maybe her relationship with her family, the Gaunts, and how their dark and proud ways influenced her. Another could be a story where Merope uses her magic in unique ways to survive in a difficult situation, given her family's fall from grace.
Marvolo Gaunt is also quite popular. As Merope's father, he represents the old, dark ways of the Gaunt family. Fanfiction might explore his relationship with Merope in more depth, like how he treated her, and whether he had any hopes or plans for her future that were different from what actually happened.

One of the most interesting aspects is her relationship with Tom Riddle Sr. In some fanfics, it's not just a one - sided love potion - induced affair. They show how she might have truly loved him and how he could have had some feelings for her too, in a different set of circumstances.
One plot idea could be exploring Merope's life before she met Tom Riddle Sr. Maybe delving into her relationship with her family, the Gaunts, and how their dark and proud heritage influenced her. It could show her as a lonely figure, trying to break free from the toxic family environment.
Her character can be developed further by emphasizing her magical abilities. Since she comes from the Gaunt family, she likely has a strong magical lineage. Fanfiction could explore her learning and mastering of spells that were perhaps lost in the family or unique to her bloodline.
It would probably involve a crossover of the two universes. Harry Potter might encounter Deidara's unique form of art which is explosive in nature. There could be battles where magic and explosive art are pitted against each other.
It might involve Harry having Wolverine - like abilities. Maybe he could have retractable claws made of magic instead of adamantium. He could use these claws in battles against Voldemort and his Death Eaters. Also, Harry could inherit Wolverine's healing factor, which would make him even more difficult to defeat. The story could also have Wolverine - type characters in the wizarding world, like a wizard with a similar tough - guy attitude and a penchant for fighting.
In such a fanfiction, it could be that Atreus has somehow ended up in Hogwarts. There could be a conflict between the students who are suspicious of this new arrival and Harry has to step in to protect Atreus. Harry would likely use his knowledge of the magical world and his courage to ensure Atreus's safety. He might also introduce Atreus to the wonders of magic, like flying on a broomstick or using potions to heal wounds.
