Well, one possibility is that it could be about Harry's struggle to adapt to his new disability. Maybe he has to learn new magic or spells to help him move around. For example, he might discover a spell that creates a temporary prosthetic leg. Another idea could be that his friends rally around him, with Hermione researching ways to heal his leg completely and Ron being his emotional support. It could also show how he overcomes the challenges in his daily life at Hogwarts, like climbing the stairs or participating in Quidditch in a different way.
When Hiccup loses his leg in the fanfiction, it often creates a turning point. He might struggle with self-confidence at first but eventually overcome it. This event might also bring the community closer together as they rally around him.
It could be a new dark wizard who has a vendetta against Harry. This wizard might have specifically targeted Harry's leg as a way to cripple him both physically and mentally. Maybe this antagonist has some sort of connection to Voldemort's old followers, seeking to finish what Voldemort started.
It could be Voldemort. Voldemort might use Harry's love as a weapon against him. He could either kill her or turn her against Harry. Another possibility is Draco Malfoy. Maybe Draco tricks Harry's love into thinking he's a better choice. Or it could be a new, unknown dark wizard who targets Harry through his love.
Well, it could have completely changed the course of the story. Maybe he would have used his powers more strategically or made different choices that affected the outcome.
Hawkeye did not lose his leg in the comics. This kind of major physical change didn't occur for him. The comic writers chose to keep his physical condition consistent without introducing such a significant alteration.
Often in such fanfictions, the plot may involve a betrayal that pushes Harry over the edge. It could be a friend or a mentor who turns on him. This sudden shift in loyalty would shatter his world view. He has always relied on the support of those around him, and when that is taken away, it becomes difficult for him to stay sane. His actions would then become erratic as he struggles to come to terms with this new and cruel reality.
