Percy could develop a more god - like sense of responsibility. Growing up on Olympus, he would be constantly exposed to the grandeur and the weight of the gods' duties. Thalia might become more confident in her leadership abilities as she is among the most powerful beings from the start. Nico could overcome his shyness faster as he is used to the presence of the gods. He would be more assertive in using his powers.
The fanfiction could explore their relationships with the gods. Since they are born on Olympus, the gods might take a special interest in them. For example, Poseidon could be even more protective of Percy, Zeus might keep a closer eye on Thalia, and Hades could have different plans for Nico. Their story could be about how they navigate these complex relationships while also trying to find their own identities. They might face jealousy from other demigods who are not born on Olympus, and have to prove themselves worthy not just because of their birthplace but also through their own deeds.
The fanfiction could also focus on their relationships. Percy, Thalia, and Nico might form a very tight - knit group, almost like a family. They would have to rely on each other in the often - cutthroat environment of Olympus. Their friendships could be tested as they grow older and face different challenges. For instance, Percy might be offered a high position in Poseidon's court that would take him away from his friends. Thalia could be given responsibilities that conflict with her loyalty to her friends. Nico might struggle with his identity as he tries to fit in on Olympus while still maintaining his connection to the Underworld.
Well, one possibility could be that they are given special status on Olympus. Maybe they are tasked with keeping the peace among the gods, which would lead to a lot of interesting interactions with the deities. They might also use their unique powers to improve the living conditions on Olympus, like Percy controlling water to create beautiful fountains or something.
It could be some of the jealous gods. Since Percy, Thalia, and Nico are living on Olympus, which is quite an unusual thing for demigods, some gods might not like their presence and try to get rid of them. For example, a god who feels that their power is being threatened by these demigods.
A possible plot twist could be that one of them is actually a secret weapon of an enemy god. For example, Nico could be unknowingly influenced by a dark force that wants to use his powers to bring chaos to Olympus.
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.
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.
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.
