Harry might develop a more solitary nature. Since spiders are often seen as solitary creatures, he could be less inclined to form large groups of friends at first. But he would also be very self - reliant.
His character may become more reserved. Growing up with the Unspeakables, who deal with secret and often dangerous magic, he would learn to keep his thoughts and actions guarded. He might not be as quick to trust others as he was in the original series.
In this fanfiction, Harry's character development could be quite complex. Growing up with Firenze, he would be exposed to centaur wisdom from a young age. This could make him more philosophical and introspective. He may question the norms of the wizarding world more often. His view on power and authority would also change. Instead of blindly following the rules set by the Ministry of Magic or Hogwarts, he would evaluate them based on his centaur - influenced values. Additionally, his relationships with other characters, like Hermione and Ron, would be different. He might not have the same initial connection with them as in the original story, but instead form new and unique bonds based on his centaur - raised experiences.
His character might develop a sense of independence earlier. Since Arachne is not a human guardian in the traditional sense, Harry has to rely on himself more. He may become more self - sufficient and resourceful.
His character might develop a more aloof side. Because he's raised by a snake, he may not be as open and friendly as in the original story. He could be more cautious and calculating in his actions.
Harry could also develop a more self - reliant and perhaps a bit of a loner personality. Since Grindelwald is not as nurturing as some other potential guardians, Harry would have to fend for himself more often. This would make him stronger in some ways but also more aloof from others, as he would be used to relying on his own skills and judgment rather than on a community or friends.
In this fanfiction, Harry's development could be centered around his understanding of family. Growing up with a scorpion, he has a very different concept of what a family is. This could lead to him having a complex relationship with the Weasleys or other surrogate families in the wizarding world. He might be hesitant to accept their love and care at first, but gradually come to realize the value of a real family. Also, his magical development could be more instinctive, like how a scorpion reacts instinctively to threats, Harry might use magic in a more impulsive yet effective way when in danger.
Harry would likely develop a very different personality. He may be more solemn and less prone to the typical teenage angst that the original Harry had. Since he is raised by Death, he might be more in tune with the darker aspects of life and magic from a young age.
Harry might be more self - assured. Charlus, being from an older time, could have a more no - nonsense approach to teaching Harry magic. This would make Harry more confident in his abilities. For example, he might not second - guess himself as much as he does in the original story.
Harry could be more independent and self - reliant. Growing up with a Pegasus rather than in a human family means he has to rely on himself and his Pegasus friend more. He would learn to fend for himself at a younger age, which would make him bolder in the face of danger.
In this fanfiction, Harry's development would deviate a lot from the original. His sense of right and wrong would be blurred. Since he's raised by devils, he may not have the same values as the normal Harry. He could be more self - centered, focused on his own survival and power gain rather than the well - being of others. His magical abilities might also develop in a more unorthodox way. Instead of learning the traditional spells for good, he might learn spells that are more harmful or controlling.
