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.
It could be that they run away to find someone. Maybe a missing demigod friend or a powerful being who can help them with a problem they're facing. Percy, Thalia, and Nico might have received a mysterious message or a vision that leads them on this journey. As they run away and start their search, they encounter various obstacles. They have to cross dangerous terrains, deal with unfriendly gods or demigods who don't want them to succeed, and also figure out how to work together effectively. Their friendship is tested, but in the end, they grow stronger together.
Well, Percy can control water, Thalia has control over lightning, and Nico can manipulate the dead. In a fight, Percy could create a wall of water to protect them from an enemy's attack, and Thalia could strike the water with her lightning, electrifying it and creating a powerful defense or offense. Nico could then raise skeletons from the ground, which the electrified water could also shock, making them more dangerous to the foes.
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.
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.
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.
In this fanfiction, Percy and Thalia could meet a powerful sorcerer who has been exiled from the magical community. The sorcerer could see potential in them and offer to teach them some ancient magic spells that could be useful against their enemies. Additionally, they may come across a group of forest spirits. These spirits could be initially hostile but after learning of Percy and Thalia's noble intentions, they could provide them with shelter and information about hidden paths that lead to safe places away from the threats they are running from.
In such a fanfiction, they might run away to avoid some great danger in the Camp. Maybe they discover a plot against demigods and feel they can't trust anyone there, so they set off on their own to find a way to stop it.
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.
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.
