Well, they might first struggle with the new powers. Percy, being used to his demigod powers, now has to deal with god - level abilities which could be overwhelming. He might accidentally cause floods or earthquakes until he gets a handle on it. Nico, who was already somewhat in touch with the darker aspects of the supernatural, may find that his new godly powers magnify this. He could have to learn to control his influence over the dead on a much larger scale. Thalia, with her experience as a hunter, might use her new godly status to protect nature in a more profound way, like being able to rejuvenate entire forests with a thought.
They adapt by learning from the existing gods. Percy could seek advice from Poseidon on how to manage his new powers without causing chaos. Nico might turn to Hades for guidance on handling the underworldly powers that come with his new status. Thalia could learn from Artemis about how to be a more effective protector. Also, they would adapt to the social structure among the gods. They have to get used to the politics and hierarchies, which is very different from their demigod lives.
I think they adapt gradually. At first, they are in awe of their new powers and status. Percy may start by testing his powers in small ways, like creating small water spouts. Nico might experiment with summoning minor spirits. Thalia could try to communicate with animals on a different level. As time passes, they become more confident and start to use their powers for bigger things. For example, Percy could use his power to stop a major tsunami, Nico to bring back a group of lost souls, and Thalia to save an entire endangered species.
One challenge is the jealousy of other gods. Since they are new gods, the older, more established gods might not like the attention they get or the new ideas they bring. Another challenge is controlling their powers. As mentioned before, going from demigod to god means a huge jump in power level, and it's not easy to get used to. For example, Percy might accidentally flood a city while trying to create a small puddle for fun.
Well, they might use their combat skills. Percy, with his control over water, could create barriers or use water attacks against threats. Thalia, with her lightning powers, can strike down enemies. They could also use their strategic thinking, like leading Nico to safe places and standing guard over him while he rests or recovers his strength.
They could be like siblings. Percy and Thalia might act as the older siblings, protecting and guiding Nico. Percy, with his leadership skills, and Thalia, with her combat abilities, would be great at looking out for the younger Nico. They could also be like cousins, with a close - knit bond but still having their own individual family heritages that sometimes create interesting dynamics.
Often, Percy is portrayed as the brave hero he is in the original works, but sometimes with added emotional depth or new challenges. Nico might be shown as more brooding and his powers more explored in detail. Thalia can be depicted as a fearless leader, especially in stories where she takes charge of a group. For example, in some fanfictions, Percy may face a moral dilemma that really tests his character, while Nico uses his powers in unique ways to help him out, and Thalia guides them through the situation with her strong leadership skills.
In fanfiction, if Percy and Thalia become gods, they might gain new powers. Percy could have even greater control over water, perhaps being able to create entire new oceans or manipulate water in ways that were previously unimaginable. Thalia, as a new goddess, might have enhanced control over lightning and the ability to protect the world from threats on a much larger scale. They could also face new challenges like dealing with the politics among the existing gods.
If they become gods, Percy could develop into a more authoritative figure. His character might become less impulsive as he has to consider the greater good of the divine world. Thalia, on the other hand, could become more empathetic. As a god, she'd have a broader perspective and might understand the struggles of mortals and other beings better.
Percy's powers might evolve in terms of his connection to the sea. Maybe he starts to communicate with sea creatures in a more profound way. He could ask for their help in escaping pursuers or finding food and shelter. Thalia's power over lightning could also be related to her emotions more closely. As she faces different challenges during their escape, her lightning bolts could become more powerful depending on her state of mind. Nico, on the other hand, might start to have more control over the undead. He could use them as scouts or to create distractions when they're in trouble. This evolution of their powers would be a result of the new and difficult situations they face while running away.
One interesting aspect of a Percy, Thalia and Nico bond fanfiction could be their adventures together. They could be on a quest to save the world from some new and powerful threat. Percy's leadership skills, Thalia's combat abilities, and Nico's connection to the underworld would make for a very dynamic trio.
In fanfiction, Nico, Thalia, and Percy are often used to explore different storylines. They are well - known characters from certain fictional universes. Fanfiction writers might use them to create alternative adventures, develop relationships between the characters in new ways, or even put them in different settings than in the original works. For example, a fanfiction could explore a romantic relationship between two of them that was only hinted at in the original. It gives fans the creative freedom to expand on the existing lore and personalities of these beloved characters.
Popularity of Percy, Nico and Thalia siblings fanfiction varies. There are those who adore the idea of reimagining their relationships in this way. It gives writers a chance to delve deeper into their backstories and how they would support or conflict with each other as siblings. For example, Percy's leadership and Nico's more brooding nature, along with Thalia's fierceness could create really interesting family - oriented story arcs. Plus, fans who love the characters are always eager to see new angles on them, which makes this type of fanfiction appealing to a segment of the fanbase.
