One common scenario could be in the face of other students' bullying. Snape might subtly step in and stop the bullies without making it too obvious. For example, he could give the bullies extra assignments or detention, which would indirectly protect Hermione from their taunts.
In some fanfictions, when Hermione is in danger during a dangerous magical experiment or a dark magic - related incident in the school. Snape, despite his usual gruff exterior, uses his vast knowledge of magic to shield Hermione. He might quickly perform a protective spell or guide her on how to protect herself.
Another scenario could be when Hermione is being wrongly accused of something. Snape, who is very perceptive, might see through the false accusations. He would then use his authority as a teacher to put an end to the accusations. Maybe he would question the accusers thoroughly and expose their false motives, all while keeping Hermione out of harm's way.
Perhaps Snape realizes that Hermione is often a target because of her Muggle - born status. In the wizarding world, there's a lot of prejudice against Muggle - borns. Snape, having experienced his own share of hardships and being an outcast in some ways, might empathize with her situation and thus be protective. Also, her friendship with Harry Potter might make Snape more watchful over her, as Harry is always in the center of many dangerous situations and Hermione is closely associated with him.
In the fanfiction, it might be shown through Snape secretly watching over Hermione during dangerous situations. For example, in a battle or when she's being harassed by other students who are prejudiced against Muggle - borns.
In some fanfictions, Snape might keep an eye on Hermione from afar. He would watch her interactions with other students or teachers to make sure she's not being bullied or manipulated.

One common scenario is when Percy is in danger during a battle with a powerful monster. Poseidon might send some kind of sea - based assistance, like a helpful sea creature to fight alongside Percy or create a protective barrier of water around him.

Often, during the Triwizard Tournament, Viktor will keep a close eye on Hermione. If there are any tasks that seem overly dangerous or if other competitors try to play dirty around Hermione, he'll step in. He might offer her advice on how to deal with the challenges based on his own experiences in the tournament. He's not just physically protective but also looks out for her emotional well - being. If she's stressed or worried about the tournament, he'll be there to comfort her.
At first, Hermione might be suspicious of Snape's new - found protectiveness. But as time goes on, she starts to see that he has good intentions. Snape, on the other hand, gradually warms up to Hermione more and more, sharing his knowledge and advice with her.
Well, one reason could be that he sees her intelligence and thirst for knowledge, which he respects. He might feel a sort of kinship as he was also a very intelligent student himself when he was younger.
In the fanfiction, Snape may protect Hermione by shielding her from the Dark Lord's influence. Given his double - agent status, he would be in a position to know if Voldemort has any plans involving Hermione. He could then take steps to keep her out of Voldemort's sight, perhaps by misdirecting Death Eaters or using his own magic to create a protective barrier around her when she's in danger.
Often, in such fanfiction, Itachi protects Naruto from the Akatsuki. Since Naruto is the jinchuriki of the Nine - Tails, the Akatsuki might target him. Itachi, being part of the Akatsuki but having his own motives, would ensure Naruto's safety from his comrades. He could mislead them about Naruto's whereabouts or lie about Naruto's power level to keep them from making a hasty move against him. Itachi might also protect Naruto from the villagers' negative attitudes. Naruto was often ostracized in the village, and Itachi could use his influence or just his presence to make the villagers think twice before treating Naruto badly.
