One fanfiction has a Slytherin who discovers a plot against Hermione. He then uses his Slytherin cunning to foil the plot and protect her. In another, during a wizarding tournament - like event where Hermione is in danger, a group of Slytherins work together to keep her safe. They might not admit it openly, but they see her as someone important to the overall well - being of Hogwarts and the wizarding world, so they are protective of her.
There are fanfictions where a Slytherin forms a study group with Hermione. And when other students try to disrupt her studies or cause her trouble, the Slytherin stands up for her. Also, in some stories, a Slytherin who has a secret crush on Hermione will protect her from any sort of harm, whether it's from a jealous rival or a dangerous magical creature that gets loose on the school grounds.
One reason could be that they see her intelligence as an asset. Hermione is known for her brilliant mind, and Slytherins, who value cunning and resourcefulness, might respect that. They could also recognize her strength in the face of adversity and be drawn to protect her as a way to show their own growth beyond the typical Slytherin - Gryffindor rivalry. In some fanfictions, a Slytherin might have a personal connection or debt to Hermione, which leads to their protective nature towards her.
One example could be a fanfiction where Hermione is in a dangerous situation in the Forbidden Forest. Sirius, being protective, immediately apparates there to save her from a group of dark creatures. He uses his advanced magic skills to fend them off and then takes Hermione back to safety at Hogwarts.
There's also 'The Slytherin Guard for Hermione'. This fanfic shows how some Slytherins, who have grown tired of the house's bad reputation, choose Hermione as the symbol of their change. They protect her from dark wizards who target her for her Muggle - born status. It's an interesting take on how Slytherins can be allies.
One example could be in a story where Hermione is in danger during a wizarding battle. Charlie, being protective, might swoop in on his dragon and shield her from the incoming spells. He could then take her to a safe location, away from the chaos of the battle, while constantly keeping an eye out for any potential threats.
Another theme is the idea of hidden alliances. In many of these fanfics, the Slytherins form a secret group to protect Hermione. This adds an element of mystery and intrigue as they work behind the scenes to keep her safe from threats, both inside and outside Hogwarts.
Well, in some versions, they might use their knowledge of the castle's secret passages to lead the troll away from Hermione. They could also work together as a team, using their Slytherin cunning to outwit the troll.
One reason could be that they see Harry as a powerful ally. They know his skills and abilities, and they want to be on his side.
One example could be a story where a group of Slytherins see Hermione being bullied by some other students for her intelligence and Muggle - born status. A Slytherin who has a secret admiration for her courage steps in and offers her a place to hide and calm down. He might share some of his own experiences of being misunderstood in Slytherin house, making Hermione realize that not all Slytherins are bad.
One great example could be 'The Slytherin Connection'. In this fanfic, Hermione starts to bond with Slytherins over a shared love for ancient magic research. Another is 'Green and Brave' where she befriends a Slytherin who is also an outcast in his own house because he doesn't believe in the pure - blood supremacy. There's also 'Snakes and Badgers' which shows how Hermione forms a study group with Slytherins and they gradually become friends as they help each other with their studies.
In a certain fanfiction, there was a village-wide competition. During one of the events, another competitor was being too rough with Hinata. Naruto stepped in, warning the competitor to be more careful around Hinata. He then stayed close to Hinata for the rest of the event to make sure she was okay.
