Ron and Lavender could be the couple in a Harry Potter Vegas wedding fanfiction. They could have rekindled their relationship and decided to do something wild and different. Their wedding could be full of food - themed magic, like a cake that levitates and feeds itself to the guests.
Harry and Luna could get married in Vegas. Luna, with her unique and dreamy personality, might be drawn to the eccentric and fun - filled atmosphere of Vegas. They could have a wedding ceremony under the neon lights, with magical creatures as their witnesses.
Since it's in Vegas, there might be some unexpected guests. Maybe some of the Vegas magicians mistake Harry for one of their own and try to include him in their act during the wedding. The wedding cake could be a multi - tiered monstrosity, with each tier having a different magical or Muggle - inspired decoration. For example, one tier could have Hogwarts castle made out of icing, and another could have the Vegas skyline. It would be a wedding that combines the best (and maybe the silliest) of both the wizarding and Muggle worlds.
Another possibility is that Harry ends up married to a Muggle he meets in Vegas. This would be really interesting as he has to navigate the differences between the wizarding world and the Muggle world while being married to someone who has no idea about magic at first. It would be a story of discovery and adjustment for both Harry and his new spouse.
Harry Potter himself could be the main character. He might be looking for a break from his usual heroic duties and end up in Vegas, where he meets someone unexpected and gets involved in a wedding challenge. It could be a new character or even an old acquaintance from Hogwarts, like Cho Chang, and they decide to go through with the challenge together.
It could be a story where Harry and Hermione decide to elope to Vegas and have a magical wedding. They might find a wizard - friendly chapel that has spells for eternal love and protection. The Weasleys could show up in a flying car to surprise them, and there would be a lot of magical chaos and celebration.
She might meet a powerful and mysterious wizard who has been hiding in Vegas for a long time. This wizard could be either a potential ally or an enemy. There could also be a group of young witches and wizards who are having their own adventures in Vegas and they all team up with fem Harry Potter for a wild ride full of magic, mystery, and fun.
Perhaps it's about Ron and Hermione. They could be on a trip to Vegas for a wizarding convention. Then they get caught up in a crazy bet that leads to a fake wedding as part of the challenge. But as they go through the motions of the Vegas - style wedding, they start to realize their true feelings for each other and consider making it a real marriage in the wizarding world.
It could be really crazy. Imagine Harry Potter and his friends in Vegas, with the Avengers around too. Maybe Iron Man could be the one to officiate the wedding. And the magic from the Harry Potter world could add some really cool special effects to the ceremony.
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.
One possible fanfiction could be that Sam and Jack decide to elope to Vegas on a whim. Maybe they've been secretly in love for a long time but couldn't act on it because of military regulations. In Vegas, they find a small chapel and get married in a simple yet heartfelt ceremony. Their friends back at the SGC are shocked but also happy for them when they find out.
Maybe Quinn and Logan could get married. They had an interesting dynamic on the show. Quinn's scientific mind and Logan's more laid - back attitude could create some really funny and heartwarming moments during the wedding planning. Their friends would be surprised but also very supportive.
