Sure does. Harry Osborn takes on the role of the Green Goblin after a series of events and developments in the comic storyline. This transformation has a major impact on the narrative and the relationships between characters.
Yes, there are many 'Harry Osborn' fanfics. You can find them on various fanfic websites like Archive of Our Own. There are different genres and themes related to his character, from friendship stories within the Spider - Man universe to his own adventures.
One good theme is his transformation. Fanfics can explore how he changes, like when he becomes the Green Goblin in some storylines. It can be interesting to see the internal struggle and how it affects his relationships.
A fanfic that stands out is 'Harry and Peter: The Unbreakable Bond'. It focuses on how they support each other. There are many scenes where they have heart - to - heart conversations that give a deep insight into their characters. The author does a great job of staying true to the essence of Peter and Harry in the original stories.
One great fanfiction idea could be Harry Osborn's internal struggle with his new - found powers in 'The Amazing Spider - Man 2'. He might be torn between using them for good, like Spider - Man, or for his own self - interests. For example, he could be constantly fighting the urge to use his powers to gain more control over Oscorp, while also being aware that Spider - Man's way of using powers is more noble.
One idea could be a story where Peter tries to protect Harry from the darker aspects of their world. Since Peter has his Spider - Man powers, he could be constantly on guard to keep Harry safe, perhaps from the enemies he made as Spider - Man. For example, a villain might target Harry to get to Peter.
