Another possibility is Heimdall. As the all - seeing guardian of the Bifrost, he would be aware of Odin's situation from the start. He could be the one trying to piece together what happened to Odin and prevent any disasters that might occur as a result of Odin's wipe. His unique abilities and loyalty to Asgard would make him a strong candidate for the main character.
In the 'odin gets wiped fanfiction', it might be that Odin has his powers wiped instead. This would change the power dynamics in the story. He would no longer be the all - powerful figure. His allies may have to step up and protect him, and his enemies might see this as an opportunity to attack. It could also be a chance for Odin to grow in a different way, learning to rely on other skills or relationships rather than just his godly powers.
In a Naruto Gets Odin's Eye fanfiction, there could be a plot where Naruto's world is somehow merged with the world of Norse mythology. The acquisition of Odin's eye could be a key factor in this merge. Naruto could use the eye to communicate with the Norse gods and gain their support in battles against his foes. This could also introduce new villains from Norse mythology. His friends in Konoha would be both amazed and a bit intimidated by his new power. Naruto would have to learn to control the power of Odin's eye quickly to prevent it from causing chaos in his village.
Well, it could be that Naruto somehow gets transported to the world where Odin exists and is mistaken for a powerful being like Odin. Maybe he has to take on Odin - like responsibilities and use his Naruto - skills in a new and strange setting.
The plot might involve Naruto being a son of Odin and having to deal with the expectations and responsibilities that come with such a heritage. He could be caught between the ninja world he grew up in and the world of Norse mythology. For example, he may need to reconcile the values of the shinobi with the values of Asgard. There could also be a conflict where he has to face off against enemies who are after the power he inherited from Odin. This could lead to him going on a journey to learn more about his true father and the powers he possesses, all while still trying to keep his identity as a ninja intact.
Well, there are quite a few main characters. Thor is a major one, with his hammer Mjolnir and his role as a protector. Loki, who is a complex character, often getting into trouble and causing problems for the other gods. And then there's Baldr, who was loved by all but met a tragic end. Also, Odin himself is an important figure in the story of his children, as he is their father and has a great influence on them.
Odin is, of course, a main character. In addition, characters from the DxD series like Issei Hyoudou often play important roles. They interact with Odin in various ways, sometimes as allies and other times as opponents, depending on the plot of the fanfiction.
Maybe it implies that the magic in Harry Potter has some connection to Odin's power in Norse mythology. So the spells cast by wizards could be related to the magic Odin wields in his own realm. For example, the Patronus charm could be seen as a form of magic similar to Odin's ability to send out his ravens to gather information.
Well, it could be that the two come from very different fictional universes with distinct magic systems and cultures. Harry Potter's world is based on a more European wizarding society, while Odin is from Norse mythology. Their values and the way magic works might clash in the mind of the fanfiction writer, leading to this 'hate' concept.
Well, without knowing the exact 'odin christmas story', generally it might include Odin as the main character. There could be elements related to the Christmas setting like a decorated tree, presents, and a festive atmosphere. Also, it might involve some sort of interaction between Odin and the Christmas traditions, like Odin being intrigued by the act of gift - giving.
