In a Harry Potter fanfiction, when Harry is in a portkey without his glasses, the plot would be full of twists. His lack of glasses would mean that his perception of the world around him is altered. This could result in him misinterpreting the intentions of other characters he meets at the destination. Maybe he mistakes a friendly character for an enemy because he can't see their facial expressions clearly. This misunderstanding could lead to conflicts that wouldn't have occurred otherwise. Additionally, his inability to see well might make it difficult for him to perform certain magical tasks that require precision, such as unlocking a magically locked door with a complex spell. As a result, he may have to find alternative ways to progress in the story, which could involve seeking help from unexpected sources or developing new skills. This would greatly change the overall plot dynamics, adding more depth and complexity to the fanfiction.
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.
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.
In a 'Harry Potter without glasses brawl' fanfiction, it could start during a Quidditch match. Without his glasses, Harry can't see clearly. He thinks an opposing team's player is trying to cheat in a really aggressive way and he jumps into a fight mid - air. This could lead to a huge brawl between the two teams. And the Ministry of Magic might get involved later to sort out the mess.
Well, perhaps in this fanfiction, Harry could be imprisoned by some dark wizards. Without his glasses, he'd be at a great disadvantage, relying more on his other senses and magical instincts. Maybe he uses his Parseltongue ability to communicate with a snake in the cell to help him escape.
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.
Perhaps a fanfiction where Sasuke discovers a Portkey in his world that leads him to Hogwarts. He has to adapt to the new magical environment and forms an unlikely friendship with Harry Potter. Together, they explore the secrets of both their worlds and use their combined skills to face challenges.
His relationships might change. Some of his friends might not recognize him at first without his glasses. This could lead to some initial awkwardness but also force him to re - establish his connections in a new way. He might also attract new attention from characters who were not interested in him before, either romantically or as potential allies or enemies. This new social dynamic could cause him to grow as a character and develop different aspects of his personality.
I'm not aware of any extremely famous fanfiction with that exact plot. There are thousands of Harry Potter fanfictions out there, but this seems like a rather specific and somewhat dark concept that may not be as widespread in well - known fanfictions. However, it's possible that there are some niche or more adult - themed fanfictions with this idea, but I can't recommend those as they might not be appropriate.
The plot could involve Harry using his magic in a different way. Since he can't see clearly, he might have to focus more on wandless magic or non - visual spells. For example, he could be trying to sense the magical energy in the cell to find weak points in the walls or barriers. And perhaps there are other prisoners in the cell with him who he has to interact with, and without his glasses, misidentifying them at first could lead to some interesting plot twists.
One possible plot could be that Harry, without his glasses and drunk, stumbles around Hogwarts in a daze. He might accidentally end up in a restricted area, like the Forbidden Forest. Maybe he has some misadventures with the magical creatures there, all while being in a drunken state and unable to see clearly. His friends would then have to go and find him.
In this fanfiction, Harry without his glasses could be in a situation where he is forced to rely on his friends more when dealing with Horcruxes. His vision impairment without glasses makes it difficult for him to be as independent as he used to be. So, Hermione and Ron play a more crucial role. For example, when they are searching for a Horcrux in a dark and dangerous place, Harry has to trust their descriptions completely. And as they progress, Harry discovers that the Horcruxes are affecting his vision in a magical way, and he has to find a way to break this spell while still trying to destroy the Horcruxes.
