Maybe Harry Potter uses his magic to create some amazing illusions on the Vegas Strip, and Supergirl is both amazed and a bit concerned about the chaos it might cause. She helps him keep things under control while also having fun with the new magical experiences.
In this fanfiction, Harry Potter could be on a secret mission in Vegas related to some lost magical artifacts. Supergirl, while patrolling the city, stumbles upon him. At first, they are suspicious of each other. But as they realize they are both after a common enemy who wants to use the artifacts for evil, they join forces. They explore the seedy underbelly of Vegas, from the back - alley casinos to the hidden magical enclaves, to stop the bad guys.
Well, it could be that a powerful dark force is lurking in Vegas, and it takes the combined skills of Harry Potter, with his knowledge of spells and magic, and Supergirl, with her superpowers, to combat it. They might start off as strangers but quickly learn to trust and rely on each other as they face this threat.
Well, it would be a really wild and interesting scenario. In fanfiction, anything can happen. Harry Potter brings his wizarding world knowledge and magic, while Supergirl has her super - powers. They might have a very unique wedding ceremony in Vegas. Maybe Harry would use magic to create some amazing effects during the wedding, and Supergirl could fly around showing off her powers. Their life together would be full of adventures, like fighting bad guys with a combination of magic and super - strength.
In a Vegas - set Harry Potter and Supergirl fanfiction, it could be a story of a magical tournament held in Vegas that attracts wizards from all over, including Harry Potter. Supergirl, intrigued by the strange magical happenings, investigates. They form an unlikely friendship as they both try to keep the peace during the tournament which is being targeted by some anti - magic groups who want to expose and destroy the wizarding community.
Well, perhaps Harry could use his magic to help Supergirl when she's facing some kryptonite - induced weakness. His spells might be able to counteract the negative effects of kryptonite for a while.
Well, perhaps Harry and his friends could visit the famous Vegas shows. They might be amazed by the magic tricks there, thinking they're similar to the spells they know. And they could explore the glittering casinos, but of course, not for gambling in a proper 'Harry Potter' way. Maybe Hermione would be interested in the libraries in Vegas, if there are any special ones.
To develop this fanfiction story, we could explore the cultural differences between the wizarding world and the super - hero world. In Vegas, they might have a wedding that combines elements of both worlds. After the wedding, they could go on adventures. Maybe they encounter a villain who is a mix of a dark wizard and a super - villain. Harry and Supergirl have to use their combined skills and powers to defeat this new threat. And as they face these challenges together, their relationship grows stronger.
Well, one thing that could happen is a really chaotic wedding. Maybe all his wizard friends show up in Vegas not quite understanding the Muggle ways. For example, Hermione might be constantly trying to figure out how all the Vegas magic tricks are done, thinking they're some kind of new wizardry. And Ron would probably be more interested in the food and drinks at the casino. Harry, on the other hand, might be a bit overwhelmed by the whole flashy Vegas atmosphere but still be happy to be getting married in such an unusual place.
Well, in such a fanfiction, Harry Potter might grow up with Supergirl's values. He could be more open about his magic in the world, as Supergirl is open about her powers. Maybe he'd be more fearless in facing Voldemort, having been influenced by Supergirl's courage.
Well, in fanfiction, it could be really interesting. Harry might first try to figure out where he is. Since he's in Vegas, he could encounter all sorts of muggle things like slot machines and big shows. He might use his magic by accident and cause a stir among the muggles. And then he'd probably start looking for a way to get back to his own world, either by trying to find some kind of magical object or by using his own magic in a new and creative way.
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.
Well, it could be that Supergirl lands in the wizarding world somehow. Maybe she's chasing a bad guy who uses magic to escape to Hogwarts. And then she teams up with Harry Potter to fight the bad guy. Harry could teach her about magic while she teaches him about her superpowers.
