Maybe Loki was too obvious in his admiration. He could have been constantly quoting Odin's teachings or trying to imitate him in public.
It could potentially make his relationships more complex. Some might view him with suspicion, thinking he has ulterior motives for being an Odin fan. Others might try to use this knowledge to their advantage, perhaps to manipulate Loki or gain favor with Odin.
One possible reason could be his feeling of being an outcast. In the original stories, Loki is often treated differently in Asgard due to his nature. He might have felt like he didn't truly belong, which could fuel his hatred. Another reason could be envy. Maybe he saw others in Asgard having things he desired, like power or recognition, and his envy turned into hatred.
One reason could be that Loki feels constantly overshadowed by Thor. In the Asgardian hierarchy, Thor is often seen as the golden child. Loki, being the more complex and misunderstood one, might run away to find a place where he can be his own person without living in Thor's shadow.
He could meet the Frost Giants. Since he has some connection to them already, they might welcome him or at least be intrigued by his presence. He could learn more about his heritage from them and maybe even form an alliance.
One possible plot could be Loki leaving Asgard after feeling constantly overshadowed by Thor. He might leave in search of a place where his skills and intelligence are truly valued, perhaps finding a hidden realm where he can start anew and build his own following without the judgment of the Asgardian court.
One possible storyline could be Loki's struggle to break free from Odin's abuse and find his true self. He might start to gather allies secretly, like some of the more sympathetic Asgardians. Another could be Loki's internal journey of dealing with the emotional trauma, perhaps having flashbacks of the abuse while trying to perform his duties in Asgard.
A theme of acceptance is also prevalent. Loki is often seen as an outcast, and Odin's love can represent acceptance of Loki's true self, whether it's his magical abilities, his different nature compared to the other Asgardians, or his past mistakes. This acceptance can be a slow and arduous process in the fics, full of emotional ups and downs.
Perhaps Percy has proven his worth through his unwavering loyalty and courage. Loki, who is used to seeing self - serving and deceitful behavior among the gods and mortals, is impressed by Percy's pure - heartedness. His actions of always protecting his friends and standing up for what is right might make Loki feel that he is worthy of respect, leading to Loki bowing to him.
One great 'odin loves loki fanfic' is 'A Father's Unspoken Love' on FanFiction.net. It delves deep into Odin's complex feelings for Loki, exploring their relationship from a more emotional and psychological perspective.
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.
