In fanfiction where Percy Jackson is alone in Tartarus, how would his powers develop?

His water - based powers might become corrupted. Instead of just controlling clean, life - giving water, he could now also manipulate dark, poisonous waters from the depths of Tartarus. This would make his powers more dangerous but also more unpredictable.

His powers would likely be much darker. He might have the ability to manipulate shadows like Nyx, using them to hide or even attack. And from Tartarus, he could have the power to cause earthquakes or open up chasms in the earth. He could also have a natural resistance to the harmful effects of the Underworld, such as the poisonous gases and the draining of energy that normal demigods experience.

He uses his wits. Percy has always been clever, and in Tartarus, he'd use that to his advantage. He'd find ways to outsmart the monsters, like using the environment against them.

His powers might develop in a way that combines the aspects of his parents. He could start with basic skills like enhanced speed and agility from Artemis, which are useful for hunting and evading enemies. As he grows older and more in tune with his Anubis side, he might develop the ability to sense death or the presence of the undead. Maybe he can also start to manipulate shadows, a power often associated with Anubis in Egyptian mythology.

If Percy was the son of Gaia and Tartarus in fanfiction, his power set would be a fascinating blend. From Gaia, he could potentially have the power of terraforming, reshaping the earth on a large scale. He might also be able to communicate with all forms of earth - bound life. From Tartarus, he could gain the ability to traverse the darkest depths of the underworld with ease, and perhaps even draw power from the primordial chaos there. This would make him a very different and much more complex character compared to his original form in the official series.

Percy's character would likely become more hardened. Living in Tartarus, he'd face constant danger and that would make him more cautious and strategic. His sense of survival would be enhanced.

Percy's development would be centered around survival and power. In Tartarus, it's all about being strong enough to endure. So he would be more focused on getting stronger. He might also be more isolated, as not many would understand his Tartarus - born nature. His relationships would be more difficult to form and maintain. He would have to learn to control his powers, which might be more closely related to the dark forces of Tartarus, without being consumed by them.

Percy's character would be very different. Growing up alone, he would lack the social skills he has in the original series. He'd be more introverted. His view of the gods would be more cynical as he has no one to tell him the 'glorified' stories. He'd have to learn about his powers through trial and error, which would make him more cautious. He may also develop a stronger survival instinct. His relationships would be different too. He might be more hesitant to open up to others when he finally does meet people. Overall, his character would be a loner with a unique perspective on the demigod world.

He might face numerous terrifying monsters. Tartarus is full of dangerous creatures, and without his friends, Percy would have to rely solely on his own skills and the power of his demigod abilities to fight them off.

His water - related powers could become more refined. Shiva has a connection to water in some Hindu myths, like his role in the Ganges river story. So, Percy might be able to control water in more complex ways, such as creating intricate water sculptures that can also be used as weapons. His ability to manipulate water temperature could also improve, allowing him to freeze water instantly or make it boil on a large scale.
