Harry could also develop more complex relationships. His capture of Pettigrew might put him at odds with some in the wizarding world who have their own ideas about how to deal with Pettigrew. At the same time, it could bring him closer to those who support his actions, like his friends and some of the Order of the Phoenix members. This would add more depth to his character as he navigates these new social and political situations within the fanfiction.
His sense of justice could be further strengthened. Seeing Pettigrew, the man who caused so much pain and destruction, in his hands makes Harry more determined to fight against the dark forces. He realizes that he has the power to make a difference and that he should use it to protect the innocent.
Harry might become more confident. Capturing Pettigrew on his own or with his friends shows his growth as a wizard. He's no longer just the boy who survived Voldemort's attack but a capable hero who can bring a criminal to justice.
One possible consequence could be that he is immediately sent to Azkaban. Since he's a known traitor, the wizarding world would want to punish him severely for his crimes, which include betraying the Potters and framing Sirius Black.
In such a fanfiction, Harry would grow in his understanding of the dark side of magic. Being captured by Voldemort means being exposed to the darkest and most malevolent forms of magic. This would make him more cautious in his own use of magic, but also more knowledgeable about how to counter dark magic. His character would also become more patient. He can't rush into things as he is in a very dangerous situation. He has to bide his time, wait for the right moment to escape or fight back. This new - found patience would be a valuable asset in his future battles against Voldemort. Moreover, he would develop a stronger sense of self - identity. He would be constantly reminded of who he is and what he stands for in the face of Voldemort's attempts to break him.
Often, Harry catches Pettigrew by using his invisibility cloak. He sneaks up on Pettigrew and then uses a stunning spell. It's a simple yet effective method that is often used in fanfictions as it plays on Harry's resourcefulness.
Definitely Hermione and Ron. Hermione would use her intelligence to analyze the situation and come up with a plan. Ron would be the more impulsive one, ready to jump into action. Sirius Black could also be involved. Since he has a history with Pettigrew, he might have some insights into Pettigrew's actions and be able to help in the search for Harry. Also, the Weasley family in general might get involved as they are close to Harry.
The story could develop with Harry being held in a dark and enchanted prison. His friends would then start a search, following any clues they can find. Voldemort might taunt Harry during his captivity, trying to break his spirit.
Harry's character often becomes more shrewd and politically aware. In Slytherin, he has to be. He learns to use his wits in different ways than in Gryffindor. For instance, he might become better at reading people's motives and using that to his advantage.
His relationship with Draco could force him to be more empathetic. Instead of just seeing Draco as an enemy, he has to live with him daily. This could lead to Harry developing a more nuanced understanding of people, and his character could become more forgiving and less impulsive in his judgments.
In these fanfictions, Harry's development can be quite complex. At first, he might rely solely on his magic, but as he faces challenges in Westeros, he starts to develop his non - magical skills too. He could learn the art of swordsmanship from the likes of Brienne of Tarth. His moral compass might also be tested as he has to make difficult decisions in a world where there are no clear - cut good or bad sides. He may find himself having to choose between saving the common people or siding with a powerful house for his own survival.
Harry's character would likely become more humble. Without his magic, he'd have to rely on his other qualities like his intelligence and determination. He might become more empathetic towards Squibs who have always been on the fringes of the wizarding world.
His magical abilities could develop in new directions. Since different families have different focuses in magic, the Greengrass family might encourage Harry to explore areas he hadn't before. For instance, if the Greengrass family is known for their potions skills, Harry could become an even better potions - maker. His self - confidence may also grow as he is part of a new family structure that supports and encourages him in different ways compared to the Dursleys.
