protectiveness

One way their protectiveness shows is in the social aspect. Slytherins are known for their loyalty to their own. They would include Draco in all their activities and not let him feel left out. If there were rumors going around about Draco, they would quickly squash them. In dueling situations, they might form a protective circle around him, using their skills to keep any opponents at bay. And when it comes to academic competitions, they would support Draco wholeheartedly, even helping him study in secret if needed.

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. If he sees someone trying to take advantage of her knowledge or skills, he would step in. Another way is that he could offer her extra help or resources for her studies privately, which shows his protectiveness towards her academic growth as well as her well - being.

She often uses her physical abilities. For example, she uses her shield to block attacks aimed at Percy.

Often, Kyuubi's protectiveness is shown through its internal dialogue or actions. For example, it might mentally warn Naruto about a character who seems untrustworthy in a yaoi relationship. Or it could physically manifest some of its power to intimidate others who might harm Naruto.

They might use their humor. For example, if someone is making Hermione feel bad by teasing her about her studious nature, Fred and George will crack jokes at the teaser's expense, making Hermione laugh and feel better, which is a form of protection in a way.

Zoro often puts himself between Luffy and danger. For example, when facing strong opponents, he'll be the first to step forward and engage, making sure Luffy is safe behind him.

Fred often uses his humor to diffuse tense situations that Hermione might be in. For example, if she's being harassed by some bullies, he'll make a joke that makes the bullies look stupid and also makes Hermione feel better.

In some fanfictions, Naruto shows his protectiveness by getting extremely angry when someone badmouths Sakura. He won't tolerate any disrespect towards her and will quickly defend her honor. He might also use his influence in the village to make sure Sakura is always safe and well - cared for.

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.

Another way is that Harry will be secretive about Draco's problems or mistakes. He doesn't want Draco to get into more trouble, so he might cover up for him in certain situations. It's like he has this instinct to shield Draco from more harm, whether it's from the authorities at Hogwarts or from other wizards.
