His character would likely become more hardened. The military life is tough and Percy would have to face a lot of difficult situations. He might become less trusting at first as he'd be in a new environment full of strangers. But over time, he could learn to rely on his new comrades. Also, his sense of responsibility would expand from just protecting his friends and family to protecting his entire unit and his country in the context of the fanfiction.
If Percy Jackson becomes a god in a crossover fanfiction, his character would experience a significant transformation. He has always been a hero who fought for the underdog. But as a god, he might have to make difficult decisions that could go against his old principles. His view of right and wrong could become more nuanced. He would also have to deal with the envy and fear of those around him. His mortality - which was a big part of his identity - would be gone, and he'd have to redefine himself in the context of immortality. His sense of time would change, and he might start seeing things from a much longer - term perspective. All these changes would make his character much more complex and different from the Percy we knew as a demigod.
Well, Percy's personality transformation would be complex if he becomes a wolf. He might become more in tune with the natural order. His sense of loyalty could intensify, much like how wolves are loyal to their pack. This could mean that he becomes even more protective of his friends, seeing them as part of his 'pack'. On the other hand, his communication style could change. Instead of relying on words, he might use more body language and growls to convey his feelings. And his relationship with authority might also shift. He could be more resistant to being ordered around, as wolves have their own hierarchy and he might see himself as an alpha in some situations. This new personality would add a whole new layer of depth to his character in the fanfiction.
If Percy becomes a werewolf in fanfiction, his social life would be turned upside down. His friends at Camp Half - Blood might be hesitant to be around him, fearing his new, more unpredictable nature. He might be drawn to other werewolves or creatures of the night, which could introduce him to a whole new set of allies and enemies. Also, his training as a demigod would need to be adjusted to account for his werewolf abilities, like learning to fight in his new form without losing control.
He might become more patient. Since he has control over time, he would understand the concept of waiting better. For example, he wouldn't be as impulsive as before when facing challenges.
He might become more war - like. Norse gods are often associated with battle, so Percy could lose some of his more laid - back Greek side.
His sense of humor might change. He could become more wry and god - like in his jokes. Also, he might be more decisive, as a god has to make big decisions quickly. However, his love for his friends and family would still be there, just expressed in a different way perhaps, more like a distant protector.
His sense of humor might change. While Percy had a very down - to - earth and sarcastic humor as a mortal, as a god, he might develop a more refined and sometimes cutting sense of humor. He could use it to put other gods in their place or to make a point during a council meeting. Also, he would likely become more confident, bordering on arrogance at times. His new powers and status would give him a boost in self - assurance, but his friends from his mortal days would probably be the ones to keep him in check and remind him not to get too full of himself.
His sense of humor might change. While he was always quick - witted as a demigod, as a god, his humor could become more refined or perhaps more sarcastic in a way that only the other gods would understand. He'd be around different company, and that would influence how he expresses himself. Also, he could become more confident, bordering on arrogant, as he has so much power at his disposal now. But at the same time, his core values of loyalty and protecting the weak might still remain, just expressed in different ways.
He might become more brooding. The Ghost Rider's power comes with a lot of darkness, and Percy, while used to challenges, would have to deal with this new, darker side. He'd still be brave, but it could be a more intense, almost reckless kind of bravery.
Her character would be different in several ways. Physically, she'd face different challenges. For example, if there are tasks that require a certain level of physical strength that were easier for male Percy, female Percy might have to find alternative ways to overcome them. Emotionally, she could be more empathetic. Since society often expects girls to be more nurturing, she might show more concern for the well - being of others. This could also change her leadership style. Instead of a more authoritative leadership, she might lead by example and through building consensus. And her sense of identity would be more complex. She'd have to balance being a girl with being a demigod, which could lead to some interesting internal conflicts.
