In fanfiction, if Harry Potter were without glasses, it would likely have a significant impact on his character arc. His glasses are not just a visual accessory but also a symbol of his 'nerdy' or 'outsider' status at the start. Without them, he could be more integrated into the 'cool' crowd at Hogwarts. He might also be more daring in his adventures as he wouldn't have to worry about his glasses getting broken or lost during battles or dangerous situations. This could lead to a more confident and perhaps even a more flamboyant Harry Potter in the fan - created stories.
In fanfiction, without his glasses, Harry Potter might be seen as more vulnerable. His glasses are like a part of his identity, and without them, he may struggle more with seeing clearly, which could add an interesting layer to his character, like when he's in a dangerous situation and his blurry vision could lead to some unexpected plot twists.
He would probably be very disoriented. Without his glasses, Harry's vision is extremely poor. In the dungeon, which is likely to be dark and full of various obstacles, he might stumble around, bump into things, and have a hard time finding his way out. This could lead to some dangerous situations as he may accidentally trigger traps or run into unfriendly creatures.
It could be really interesting. Maybe without his glasses, Harry would seem more vulnerable, and Malfoy might take advantage of that in a different way than in the original story. They could have more intense eye - to - eye confrontations that are different from the ones where Harry is hidden behind his glasses.
It could be a really interesting take. Maybe without his glasses, Harry has to rely more on his other senses like magic - enhanced hearing or something. And Nagini being there adds a whole new level of danger. It could be that Nagini is used by Voldemort to target Harry in a new way, since Harry can't see clearly. It might also show a side of Harry that is more vulnerable, and his relationship with Nagini could be explored in a very different way than in the original books, like she could be a sort of shadowy figure that he senses but can't quite make out without his glasses.
In fanfiction, if Harry Potter is in a portkey situation without his glasses, it could lead to a whole new set of adventures. His lack of clear vision could make him more reliant on his other senses, like his sense of hearing or magic - sensing abilities. Maybe he stumbles upon a magical object or creature that he wouldn't have noticed if he had his glasses on because he's forced to explore his surroundings in a different way. It could also create an opportunity for character development as he has to overcome the obstacle of his poor vision in this new and often unpredictable situation.
A fanfiction like this could explore Harry's character in a new light. Usually, his glasses are a part of his iconic look. Without them, he's not only physically different but also psychologically. He might feel more exposed and less confident. This could change how he approaches situations with the Snatchers. For instance, he might be more hesitant in making decisions or using magic, which could have a big impact on the outcome of any encounters.
The plot could change significantly. For starters, his initial reaction to the portkey journey and arrival would be different. Instead of quickly taking in the scene, he'd be fumbling around. This could lead to him being left behind by his companions if they're in a hurry. Also, if there's a mystery to solve at the destination, his impaired vision might make him overlook crucial clues that are visible only to those with good eyesight.
His character could become more self - reliant. Without his glasses, he has to find new ways to navigate the world, which might make him more independent. He would learn to trust his other senses more.
One possible plot for a 'Harry Potter in prison without glasses' fanfiction could be that Voldemort or his followers have managed to frame Harry for a serious crime. In prison, without his glasses, Harry is constantly disoriented. He has to learn to adapt quickly. There could be a new character, perhaps a sympathetic prison guard or a fellow inmate who helps him get by. Harry could also discover some hidden magic within the prison walls that he can only access because he is in this vulnerable state without his glasses. This new magic could be the key to his escape and also to defeating Voldemort's plans in the long run.
It could be part of a magical curse. The curse made him lose his glasses and trapped him in a cage. Maybe it was cast by a jealous student at Hogwarts who wanted to get back at Harry for always being in the spotlight. In the cage, Harry has to figure out how to break the curse and get his glasses back, all while dealing with the limitations of his impaired vision.
