His sense of responsibility would likely increase even more. Harry has always been responsible, but as a priest, he would feel accountable for the spiritual well - being of others. He would become more solemn and less impulsive perhaps. His Gryffindor impulsiveness might be toned down as he takes on a more serious religious role.
If Harry Potter becomes a priest in a fanfic, his personality would transform in multiple ways. He would be more patient. Considering all the times he was impatient with people like Snape, as a priest, he would need to practice patience. He would also be more forgiving. Harry has had a lot of grudges in the past, but as a priest, he would have to let go of those negative feelings. He would be a source of comfort and wisdom for those around him, which is different from his more action - oriented past self.
Well, Harry Potter's personality would change quite a bit if he became a priest in a fanfic. He would become more empathetic. Since he has a lot of experience with pain and loss, he could use that to truly understand others' suffering in a religious context. He would be more of an introvert in a way. His life would be more centered around prayer and meditation, which are not as social as his previous adventures. And his leadership style would change from a more battle - oriented one to a spiritual - guidance - based one.
He might become more brooding and less open. Harry has always been a bit of an open book, but Vader's influence could make him more withdrawn as he contemplates power and the dark side.
His relationships would be in shambles. Hermione and Ron would be horrified and try to stop him. They might not even believe it at first, thinking it's some sort of dark magic trick. But as Harry delved deeper into the Sith ways, they'd realize it's real.
He might become more authoritative. Since he has the power of an emperor, he would need to make tough decisions and be more assertive in his commands.
He might become more stealthy and reserved. Instead of being as open as he was in the wizarding world, he'd have to be more secretive as a ninja.
His positive and determined personality would turn into a cynical and cruel one. He might lose his sense of justice and become self - centered.
Harry's confidence would likely grow in a different way. Instead of the boy - who - lived bravado, he'd have a more quiet and self - assured confidence. He'd know that he has powers and knowledge that others don't, and this would show in his demeanor. He might be less impulsive and more calculating, which could both help and hinder his relationships and his ability to protect the wizarding world.
He might become more brooding. The need to control his bloodlust could make him withdrawn.
His story would change drastically. He'd no longer rely solely on magic spells. Instead, he'd use the Force. His training would shift from Hogwarts classes to Jedi training with a master. His adventures would likely take him to different planets as well as the magical world. His relationship with Dumbledore might change as he now has a new set of mentors in the Jedi Order.
If Harry Potter becomes a Pokemon fanfic, the whole dynamic of the story would shift. Instead of focusing on Voldemort and the dark arts, Harry would be more concerned with becoming a great Pokemon trainer. He would travel to different regions in the Pokemon world, like Kanto or Johto, instead of Hogwarts and its surrounding areas. His friends, like Ron and Hermione, might also get involved in the Pokemon adventure. Hermione would be reading books about Pokemon, trying to understand their biology and behavior, while Ron would be excited about the food in the Pokemon world. And the Hogwarts professors would be left wondering what has happened to their star pupil.
His personality would likely become more complex. He could be more withdrawn in some ways, as he might not fully trust others easily. Since Lucifer is associated with power and manipulation, Harry might also show tendencies to manipulate situations to his advantage. He would have a different view of loyalty, perhaps seeing it more as a tool for his own ends rather than an inherent virtue.
