Dudley often shows his jealousy through mean actions. He might bully Harry more in fanfiction, like taking his things or pushing him around. It's his way of trying to assert dominance since he feels inferior to Harry in other aspects, especially when it comes to Harry's magical world.
In fanfiction, Inuyasha might show his jealousy of Koga by getting overly protective of Kagome.

He may also try to physically insert himself between Koga and Kagome, as if marking his territory.
Well, Sasuke could show his jealousy in a more subtle way too. He might start training harder or trying to outdo Naruto in certain skills when he feels threatened by someone else's relationship with Naruto. Sometimes, he might give Naruto the cold shoulder but then secretly keep an eye on him to see who he's with. It's all about that complex dynamic between them in the fanfiction world.
Well, perhaps Dudley uses his street - smart knowledge. He might teach Harry some rough - and - tumble moves he's learned from his own scuffles in the neighborhood. For example, showing Harry how to dodge a punch quickly.
Well, often in fanfiction, Carmelita's jealousy can be seen through her actions. She may become overly protective of Sly. If there's a new female character around Sly, Carmelita might start hovering around him more, trying to insert herself into every situation he's in with that other character. It's like she's staking her claim in a very obvious way. And she could also be a bit more snappy or short - tempered with Sly, which is out of character for her usually calm self when she's not jealous.
In some Dudley Protects Harry fanfictions, Dudley's character development often starts with a significant event. For example, he might witness the true danger Harry is in from the wizarding world. This makes him realize that his previous bullying was petty. He then begins to feel a sense of responsibility towards Harry. He may start to learn about the wizarding world to better protect Harry, gradually changing from a bully to a protector. This transformation can also be influenced by his own growth in understanding family and loyalty, as he finally sees Harry as more than just the 'freak' he once thought him to be.
Perhaps Dudley finally stands up to his father's cruel treatment of Harry. Maybe he realizes that Vernon's behavior towards Harry is wrong and uses his own physical strength or some clever ruse to get Harry out of a difficult situation Vernon has put him in.

In some fanfictions, Harry Potter shows his strategic genius by outmaneuvering his enemies in battles. For example, he might use his knowledge of magic in unexpected ways to gain an advantage.
