For the best man, it could be Sirius Black if we imagine a scenario where he somehow survived. He was like a father figure to Harry. And for the maid of honor, maybe Fleur Delacour. She and Hermione have a mutual respect, and Fleur could bring some elegance and a touch of Beauxbatons charm to the wedding.
In a different take, Neville could be the best man. He has grown into a brave and reliable friend to Harry. As for the maid of honor, Luna would be a great choice. Her unique perspective and friendship with Hermione would make her perfect for the role. She could add some really interesting and whimsical elements to the wedding preparations.
Harry would be an obvious choice for the best man. He's Ron's best friend, they've been through so much together. As for the maid of honor, it could be Ginny. Ginny and Hermione are good friends, and Ginny is also Ron's sister, so it would be a very fitting choice.
It's possible that Draco could ask his father, Lucius, to be his best man, as a way of mending their relationship. Lucius, having changed his ways after the war, would be honored. For Hermione, she could choose Professor McGonagall as her maid of honor. McGonagall has been like a mentor to Hermione, and her presence would be very meaningful at the wedding.
Neville could also be considered as the best man. He has grown into a very brave and reliable wizard, and his friendship with Harry has deepened over the years. His presence would add a touch of stability. Regarding the maid of honor, Pansy Parkinson could be an interesting choice. If she has had a change of heart over the years, she could bring a different dynamic to the bridal party, with her strong Slytherin personality.
In some fanfictions, Nico could be the best man for Percy. Their relationship has evolved over time, and Nico has proven himself to be a loyal friend. For Annabeth, Thalia could be the maid of honor. Thalia is strong - willed and has known Annabeth for a long time, so she would be a great support during the wedding.
I think Harry might choose Hagrid as his best man in a really unique fanfiction scenario. Hagrid has been like a father figure to Harry in some ways. He would be so proud and happy to stand by Harry on his wedding day, even if he might be a bit clumsy. For Ginny, her older brother Bill could be the maid of honor in a gender - bending twist. Bill is protective of Ginny and they have a great relationship. He could bring a sense of family and tradition to the role.
Zuko could be the best man. He has a deep respect for Aang and has become a close friend. His presence would also symbolize the newfound unity between the Fire Nation and the rest of the world. As for the maid of honor, maybe Yue. Even though she's no longer alive in the physical sense, her spirit could be present in a way. She was an important figure in Katara's life, and it would be a very emotional and spiritual choice.
For the best man, it would likely be Shikamaru. He's Naruto's good friend and is smart and reliable. He could help Naruto with any last - minute jitters or problems. As for the maid of honor, Ino would be a great choice. She and Sakura have a long - standing friendship, and Ino would be very involved in making sure Sakura's day is perfect.
I think Lock, Shock, and Barrel could be an interesting choice for best man, in a sort of comical way. They could be trying their best to be proper and helpful during the wedding preparations, but of course, they'd get into some minor mischief along the way. For the maid of honor, the little girl from Christmas Town who once helped Jack understand the true meaning of Christmas could be a sweet choice. She could bring some of the warmth and innocence of Christmas to Sally's side on her wedding day.
Maybe Gary could be the best man. He has a long - standing relationship with Ash, and they've had their rivalries and also moments of mutual respect. Regarding the maid of honor, it could be Miette. She and Serena have had their interactions, and she could add a bit of fun and sass to the wedding party.
Lumière could be the best man. He is charming and has a great sense of humor. He could give a very entertaining speech at the wedding. For the maid of honor, it could be one of Belle's friends from her village. Someone who has known her for a long time and can share stories about her childhood and how she has grown into the woman she is today.
