Obviously, Harry Potter himself would be a main character. He'd be the one leading the way through the Vegas challenges, using his Gryffindor courage and his skills as a wizard.
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.
Well, it could be about Harry and his friends going to Vegas during a break. Maybe they get involved in a magical challenge there, like a wizarding duel tournament with a Vegas - style twist, with big magical prizes and flashy spells.
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 a powerful dark wizard who has escaped from Azkaban and has made Vegas his new lair. He's using the chaos and glamour of Vegas to hide his dark magic activities, like creating dark spells and recruiting followers. Harry would have to face this wizard to protect both the wizarding and Muggle worlds.
Obviously, Harry Potter himself would be the central character. Hermione could be part of the harem, as she has always been close to Harry. Luna Lovegood might also be there, with her unique and dreamy personality. Additionally, some new original characters could be introduced, like a powerful witch from a Vegas - based wizarding family.
He could marry a Muggle he meets by chance in Vegas. Maybe a singer or a waitress who has a big heart and an open mind towards the strange things Harry might do or say because of his wizarding background.
He could marry Ginny. They already have a strong connection in the original series. In a Vegas - themed story, they might decide to run off to Vegas for a fun and exciting wedding. It would be a way to break free from the traditional wizarding wedding norms.
Harry Potter himself is often a main character. After all, he's the central figure in the original series, so it's natural for him to be involved in these fan - created challenges. Hermione and Ron are also common main characters as they are Harry's closest friends and are often by his side in adventures.
Obviously, Harry, Hermione, and Ron would be the main characters. Hagrid could also be there, being his large and friendly self, perhaps a bit out of place in the glitzy Vegas environment. Dumbledore might make a cameo appearance, guiding them from afar or sending them some mysterious messages. Neville could tag along too, excited to explore a new place.
Neville Longbottom could be a main character. He has always had the potential for great things and in a world without Harry, he would be likely to step into the spotlight. He has the courage and the connection to Hogwarts that could make him a central figure in the fight against evil.
