One reason could be his ambition clashing with his family values. Percy is often very career - driven in the original story. Maybe in the fanfiction, his pursuit of success at the Ministry of Magic leads him to make decisions that isolate him from his family, ultimately causing him to run away. For example, he might be given an important assignment that goes against the Weasley family's stance on certain magical politics.
Perhaps he discovers a dark secret within the Ministry or his family that he can't handle. It could be something related to a hidden agenda among the Ministry officials that he stumbles upon. Unable to face the truth or fearing for his safety, he decides to run away. Like if he found out that some high - ranking officials were involved in illegal magic experiments and he was afraid of being silenced.
One possible reason could be family pressure. In the Weasley family, there are high expectations and a lot of chaos. Percy might feel suffocated and decide to run away to find his own path. Maybe he's tired of always being in the shadow of his more popular siblings and wants to prove himself on his own terms.
Well, perhaps they ran away because they were tired of all the rules and restrictions at Hogwarts. Harry had always had a bit of a rebel streak, and Hermione might have finally agreed that they could achieve more on their own. Also, it could be related to a prophecy that they thought was best dealt with away from the prying eyes of their friends and teachers.
The existence of such 'percy weasley abused fanfiction' could also be due to the sheer freedom of the fanfiction realm. There are no strict editorial guidelines like in official publishing. Writers can let their imaginations run wild, and sometimes that results in extreme interpretations. Also, they may be influenced by other dark fanfictions they've read and want to create something similar but with Percy Weasley as the focus, whether it makes sense in the context of the original character or not.
Perhaps he was influenced by some new friends he met who had a different lifestyle or view of the world. They might have convinced him that running away from home was an exciting adventure and a way to break free from the restrictions at home.
One possible reason could be that Gon is on a quest for self - discovery. In the Hunter x Hunter world, there are so many mysteries and he might feel the need to explore on his own, away from his friends and mentors. He could be running away to find out more about his father, Ging. Maybe he thinks that by distancing himself from the normal Hunter path, he can uncover secrets that others are hiding from him.
Well, perhaps they run away because they discover some dark secrets about the wizarding world that others don't want them to know. They might fear for their lives if they stay, so they choose to flee. It could also be that they are simply seeking adventure. The daughter of Harry and Sirius might inherit their adventurous spirits, and they both decide to run away to explore the unknown parts of the wizarding world and beyond.
It would cause a great deal of sadness. Molly Weasley, being a very family - oriented mother, would be heartbroken. She might constantly worry about Percy's well - being and feel like she failed as a mother. The younger Weasley siblings would also be affected. Ron, for instance, might feel confused and a bit betrayed, as Percy has always been a role model to some extent.
Well, she might run away because she feels overshadowed by her father's fame. Everyone always talks about Tony Stark, Iron Man, and she may feel like she's just an afterthought. Maybe she wants to find her own identity away from the Stark name.
Perhaps she feels alone. If the father of the baby is not around or is not supportive, she might feel like she has no one to turn to in the village. So, she decides to run away to start anew somewhere else where she can raise the baby on her own terms. Also, she could be running away from her own responsibilities as a ninja. The pregnancy might make her question her role and future in the ninja world, and she chooses to escape from it all.
One possible reason could be that she feels overwhelmed by her responsibilities. In the world of Equestria, Twilight has a lot on her plate, like studying magic, taking care of Spike, and helping her friends. In fanfiction, the writer might explore the idea that she just needs a break from it all and runs away to find some peace.
