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.
A fanfiction could focus on Harry Osborn's life at school. He's rich and popular, but in this version, he's also secretly dealing with family issues related to his father's business. He could cross paths with Peter more often at school, and their interactions could be a mix of rivalry and a budding friendship.
I like the storylines where Harry tries to break free from the Goblin curse. It shows his internal struggle and his will to be a better person. It's a powerful concept that adds depth to his character.
One possible scenario is that Spider - Man, now as Venom, has to face new and different villains. His powers have changed, so the way he battles foes would be different too. He might have an advantage against some villains who were previously difficult to defeat, but at the same time, he could also attract the attention of more powerful enemies who see the Venom - powered Spider - Man as a greater threat.
Well, perhaps in the fanfiction, Spider - Man is tricked into becoming Venom. A villain could manipulate the situation so that the Venom symbiote attaches to Spider - Man. As Venom, he starts to see the world from a different perspective. His relationships with his friends and family become strained as they don't recognize the changed Spider - Man. He has to find a way to break free from the symbiote's control while still using its power for good.
There's a fanfiction where Harry Osborn teams up with Spider - Man to fight a new threat in the city. It's an action - packed story that really delves into Harry's character. He's not just the villain, but a complex person with his own motives and desires. It gives a fresh perspective on his role in the Amazing Spider - Man 2 universe.
The fanfiction could revolve around Harry Osborn trying to take over Oscorp in a different way. Instead of following his father's footsteps directly, he could use his powers to try and reform the company from within. He might face opposition from the board members and other villains who have their own plans for Oscorp. This would put Harry in a difficult position where he has to use his wits and powers to achieve his goals.
His appearance would change drastically. As Venom, he would be taller, more muscular, and have a menacing look. His costume would be black with the big white spider logo. Also, his relationships would be affected. His friends might be scared of him, and he might have to prove that he is still the same person inside, despite the exterior and some personality changes.
