They might meet a group of friendly yeti - like creatures that only come out during the Christmas season and help them on their ride.
There could be a magic sleigh pulled by Thestrals, which are invisible to those who haven't seen death. Only Harry and a few of his friends can see them, and they use this sleigh to travel to a hidden part of the Forbidden Forest where there's a magical Christmas tree that grants wishes.
In this fanfic story, perhaps it's a group of friends who decide to go on a motorcycle ride on Christmas day. They ride through different neighborhoods to spread Christmas cheer. They could stop at orphanages or old - age homes to give out gifts and sing carols.
Santa Claus himself could be a character. He could be taking a test ride of his new sleigh, making sure it can handle all the presents for the children around the world.
A 'Seamus Harry Potter Flick Christmas Story' might be centered around Seamus's family traditions during Christmas. Seamus could bring a 'flick' (which could be a family heirloom or a new magical discovery) to Hogwarts for Christmas. This 'flick' could have some special powers that get activated during the Christmas season. For instance, it could create beautiful light displays around the Gryffindor common room or help Seamus communicate with his family in a more magical way during the holidays. And of course, there would be all the usual Hogwarts Christmas fun like the feast and gift - giving involved in the story.
It could be about how the wizarding world responds to the muggle tragedy. Maybe they send help secretly or use magic to prevent similar disasters in the future.
A 'Harry Potter in Fallout' fanfic could center around Hogwarts being in the Fallout world. The Sorting Hat could take on a new role, perhaps sorting students based on their ability to survive in the wasteland. Spells could be adapted for combat against the new enemies like raiders and super mutants.

It could be a really unique crossover. Maybe it's about Gohan finding himself in the world of Harry Potter and using his Saiyan powers to help in the wizarding battles.

It might also be a story where the characters from both universes learn from each other, like Harry learning about Gohan's training and discipline.
Well, perhaps in this fanfic, the Undertaker's skills and personality are merged with Harry Potter. The Undertaker is known for his intimidating presence and unique fighting style. Harry Potter could incorporate these traits into his own character. It could also be set in a world where the magical elements of Harry Potter co - exist with the more macabre world of the Undertaker. There could be a plot where Harry has to use the Undertaker's methods to solve a mystery in the wizarding world, like finding out who is behind a series of disappearances that seem to have a connection to dark magic and the underworld.
In a 'Harry Potter is Undertaker fanfic', perhaps Harry Potter discovers a hidden connection between the wizarding world and the world of the Undertaker.

Well, it could be about Harry Potter somehow being a version of Loki in the wizarding world. Maybe he has Loki's mischievous nature and ability to deceive. He could use his magic in ways that are more like Loki's tricks, like creating illusions to fool his enemies or classmates at Hogwarts.
