In a fanfic, if Harry Potter and Wednesday Addams were to interact, their different outlooks on the world would create an interesting dynamic. Harry has grown up in a world of magic but also with a sense of hope and the fight between good and evil. Wednesday comes from a world that is more accepting of the dark and the strange. Harry might introduce Wednesday to the concept of using magic for good, while Wednesday could show Harry that not all that is dark is necessarily evil. For instance, she might have a different way of dealing with dark creatures, not just seeing them as something to be defeated but perhaps understanding them on a deeper level.
If they were in a fanfiction together, Draco Malfoy would likely be very disdainful of Wednesday Addams. He would see her as an outsider and someone not worthy of his attention. However, Wednesday would not be intimidated by Draco at all. She would probably give him a cold stare and some cutting remarks. Harry, on the other hand, would try to keep the peace between them. He might see potential in both of them and hope that they could work together if the situation called for it. For example, if there was a threat that combined the dark magic of the wizarding world and the strange mysteries that Wednesday often deals with.
Well, Wednesday would likely be very matter - of - fact in her interactions. She doesn't have time for small talk. Harry, used to the more chatty and friendly environment of Hogwarts, would have to adjust. But as they interact more, Harry would see that Wednesday has a sharp mind and a strong will. Wednesday would see Harry's courage and determination. For example, if they were in a dangerous situation in the wizarding world, like facing a group of dark wizards, Wednesday's ability to stay calm and think rationally in the face of danger would be an asset. And Harry's magical skills would be useful to Wednesday, who has no wizarding training. They'd form a unique bond based on mutual respect for their different strengths.
Harry Potter and his friends would be both shocked and intrigued by the Addams family. Ron would be constantly freaked out by their strange habits, like Gomez's love for knives and Morticia's long black hair that seems to have a life of its own. Hermione, however, would be eager to learn about their family magic, if they have any. She might try to study it like she does with other forms of magic in the wizarding world. And Harry would probably be a bit cautious but also curious, seeing as he has his own experience with dark and strange things.
First, you need to do your research on both universes. Know the characters well, their backgrounds, their personalities. For Harry Potter, understand the magic system, the Hogwarts houses, etc. For Wednesday Addams, know her family, her love for the macabre. Then, think of a creative way to bring them together. It could be a portal between their worlds or some sort of magical accident. When it comes to the 'lemon' part, build up the relationship gradually. Don't rush into it.
In a fanfic, Draco Malfoy would probably look down on the Addams family at first, seeing them as 'weird' and not up to his pure - blood standards. But the Addams family wouldn't care about his snobbishness at all. Instead, they would just be themselves. Morticia might even make Draco a bit uncomfortable with her elegance and mysteriousness. And the Addams family's pets, like Thing, could cause some chaos in Hogwarts, which would be both amusing and a bit of a headache for the Hogwarts staff.
A fanfiction could be set in a world where Hogwarts has an exchange program with Nevermore Academy (Wednesday's school). Harry Potter is chosen to go to Nevermore, and Wednesday is sent to Hogwarts. At Hogwarts, Wednesday has to deal with the magical chaos and the rather more optimistic students compared to her own schoolmates. Meanwhile, Harry has to navigate the strange and often macabre world of Nevermore, and they both learn a lot from each other's worlds.
In a fanfiction, Wednesday Addams could visit Hogwarts. She would probably find the castle fascinating, but also a bit too cheery in some parts. She might make friends with some of the darker - themed students, like those from Slytherin. And she could introduce them to her pet spiders and other creepy - crawlies. Harry would be intrigued by her and her family's attitude towards death and the afterlife, which is different from what he has learned in the wizarding world.
The characters can interact in many ways. For instance, Harry Potter could visit the Addams Family mansion. He might be a bit shocked at first by the spooky decor and the family's rather unusual habits, but he could also find common ground. Harry has dealt with his fair share of dark and strange things, so he might be more accepting than others. On the other hand, Wednesday Addams could visit Hogwarts. She would likely be unimpressed by the 'normal' magic and might try to find the darker corners of the school and the secrets that the other students are too afraid to explore.
Well, a lemon fanfiction usually implies some sort of romantic or at least very close relationship scenario. In this case, combining Harry Potter and Wednesday Addams, it could be a wild and out - of - the - box story. Maybe it's about a crossover universe where Harry, with his magical world, meets Wednesday's dark and spooky world. And perhaps there's a strange attraction between them that defies the norms of their respective universes.
A great plot could be a duel between Harry and Wednesday. Harry uses his wizarding spells while Wednesday uses her unique skills of dealing with the spooky and unexpected. It would be a battle of two very different kinds of power. Another plot could be a quest where they both search for a lost magical artifact that has the power to bring out the darkest secrets of both their worlds. They have to overcome many obstacles together, like strange creatures and dark magic spells.
