How does Percy Jackson's personality change after returning from Tartarus in fanfic?

He could be more cautious. The perils of Tartarus might have made him less reckless. For example, he might think twice before getting into a fight or taking risks that he used to take without hesitation.

Percy could become more self - reliant. In Tartarus, he can't always count on his friends or his powers in the same way as on the surface. So he'll have to dig deep within himself to find new strengths. He may also become more strategic in his thinking, as one wrong move in Tartarus could mean death.

It makes him more hardened. The harsh conditions force him to become tougher both physically and mentally. He has to constantly be on guard and ready to fight, which sharpens his reflexes and his ability to think quickly in dangerous situations.

Nyx could be a great main antagonist. She's a primordial goddess of the night and Tartarus is her domain in a way. She might see Percy and his friends as intruders and try to stop them from leaving or achieving their goals. She could use her power over darkness and the unknown to create all sorts of obstacles for them.

His confidence would likely soar. As a god, he'd know he has more power and capabilities. So he might be more assertive in his actions and decisions.

Perhaps he could make an alliance with some of the less hostile creatures in Tartarus. There might be beings who are also tired of the chaos and want to help Percy in exchange for something, like a promise to free them from Tartarus if he ever gets the chance. Percy is known for his charisma and ability to make friends, even in the most unlikely situations.

Grover could also be an ally. His connection to nature might give Percy some unique advantages in Tartarus. Additionally, some of the less hostile creatures in Tartarus, like the friendly Cyclopes, could side with Percy. They might see him as a more just ruler compared to the chaos that usually reigns in Tartarus. Also, Chiron, with his vast knowledge and experience, could offer guidance from afar, which could be considered a form of alliance.

His relationship with Annabeth would be severely strained. Annabeth, who has always known Percy as Poseidon's son, would be confused and a bit distrustful. She might think Percy has been lying to her all this time. His friends at Camp Half - Blood would also be divided. Some would be scared of his new powers and his connection to Tartarus, thinking he could be a danger. However, some might be more understanding, especially those who have faced their own identity crises. His relationship with the gods would also change. The gods who were once somewhat friendly or at least neutral towards him might now see him as a threat. Zeus, for example, would be extremely wary of Percy's Tartarus - related abilities.

He might become more fierce. As a dragon, he has the physical power to match his temper at times. He could be less patient with those who oppose him.

His confidence might increase. Aphrodite is all about charm and allure, and being around her could rub off on Percy. He might become more self - assured in social situations, which is quite different from his sometimes - awkward self in the original stories.
