The theme of unrequited love can also be present. In some fanfictions, Kakashi's protectiveness might stem from his hidden feelings for Sakura. He might be too afraid to admit his love but his actions of protection speak louder. This adds an interesting layer of complexity to their relationship in the fanfiction world.
Another theme is the idea of family. Sometimes, these fanfictions portray Kakashi as seeing Sakura as a younger sister or a family member he has to protect. This can lead to some really heart - warming moments where he goes above and beyond to keep her out of harm's way.
Often, there's a theme of redemption as well. The Slytherin character may have had a less - than - perfect past or be associated with some not - so - nice Slytherin traits. But by protecting Hermione, they are on a path of redemption, proving that they can be more than what others expect of them. For example, they might be trying to make up for past wrongs done by their house mates or their own previous actions.
One key element is the bond. Kakashi sees a lot of himself in Naruto, especially the loneliness and the need to prove oneself. So he's extra protective. For example, in many fanfictions, he'll stop anyone from badmouthing Naruto because he knows how it feels to be an outcast.
Another theme is growth. As Sasuke becomes more protective, he also grows as a person. He learns to open up more, to trust his instincts about protecting Naruto. This growth can be both in terms of his ninja skills, as he hones them to better protect her, and in his emotional intelligence, as he becomes more attuned to Naruto's needs.
One common theme is mentorship. Since Kakashi is a more experienced ninja, there's often a theme of him mentoring Sakura, which then can develop into something more. Another is the theme of unrequited love, where either Sakura has feelings for Kakashi that she has to hide or vice versa.
Emotional connection is another prevalent theme. Some fanfics show a deeper, more personal bond between them that might not be as obvious in the original series. This could be in the form of shared secrets, or just a special understanding they have for each other.
A frequent theme is the exploration of their relationship outside of the main Naruto storyline. For example, in some fanfics, they are the main characters in a post - war world where they have to rebuild the village together. Also, the theme of mentorship turning into something more, like a romantic relationship, is quite common. Kakashi starts as Sakura's teacher but as the story progresses, their relationship deepens in a different way.
One common theme is Clint getting injured during a mission and the Avengers rallying around him. For example, he might be seriously hurt in a fight against a powerful villain, and then the rest of the team goes all out to protect him while he recovers.
A theme that often comes up is his physical pain and how he endures it. This can be used to show his strength and tenacity. For example, in a battle - themed fanfiction, he endures great pain but still manages to fight for the sake of his village. Also, the theme of self - discovery through pain is common. As he experiences pain, he learns more about himself and his limits.
One common theme is the deepening of their relationship. When Derek is protective of a hurt Stiles, it often shows a level of care that goes beyond friendship, leading to a romantic or very close bond. Another theme is Derek's struggle with his werewolf instincts. He has to control his aggression towards the source of Stiles' harm while also being gentle with Stiles. For example, if a rival pack hurt Stiles, Derek might want to go on a full - scale revenge mission but has to hold back to take care of Stiles first.
One common theme is loyalty. Peter sees Tony as a mentor and a friend, so he is extremely loyal and will do anything to protect him. For example, in many fanfictions, Peter will put himself in harm's way without hesitation when Tony is threatened.
