In this fanfic, Percy, Thalia, and Nico find themselves on a quest together. Along the way, they start to bond like a family. Percy shares his stories of the sea, making Nico laugh with his tales of sea monsters. Thalia shows them her skills in archery, and they all learn from each other. At night, they sit around the campfire, sharing their hopes and fears. Nico reveals his insecurities about his powers, and Percy and Thalia offer their support, telling him he's an important part of their 'family' of demigods.
They could be trapped in a maze. Percy uses his water powers to find a way out, Thalia uses her lightning - infused senses to detect any hidden paths, and Nico uses his connection to the Underworld to sense any danger. As they struggle through the maze, they rely on each other's strengths and form a closer bond.
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.
A fanfic that stands out is 'The Trio's Trials'. This one is interesting because it not only focuses on their physical adventures but also their emotional growth. We see Percy dealing with his leadership role, Thalia coming to terms with her past, and Nico learning to open up more. The character development throughout the story is quite engaging.
Well, in the 'Percy, Thalia and Nico are family' fanfiction, they could form a very unconventional family. Percy, with his heroic nature, would be like the big brother figure. He'd be the one to inspire the others. Thalia, as a daughter of Zeus, would bring her own kind of strength and pride to the family. And Nico, with his dark and mysterious powers, might seem a bit of an outcast at first but would be deeply loved and accepted by the others. Their family might be centered around their shared experiences in the world of demigods, facing monsters and gods alike, and through those experiences, their bond would grow stronger.
Often, their family dynamics are complex. Percy is known for his loyalty and can be like the glue that holds them together. Thalia, being the older and more headstrong one, might act as a protector. Nico, with his dark past and powers, could be the one who adds an element of mystery to the family. They might have moments of bickering, like any normal family, but also show deep love and support for each other when facing big challenges.
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 fight due to a prophecy. If there's a prophecy that involves one of them being the 'chosen one' and the others think they should be, it would create a lot of tension. For instance, if the prophecy says that only one of them can save the world from a certain doom. Percy, being the main character in many stories, might be assumed by the others to be the one, but Thalia and Nico may believe they have just as much right. Their struggle for that role could lead to a fight. And during the fight, they would use their unique abilities. Percy would call upon the water, Thalia would summon her lightning bolts, and Nico would raise the dead to fight on his behalf.
You can start by looking on fanfiction.net. It has a large collection of fanfics related to Percy Jackson and his friends. Just search for 'Percy Thalia Nico' in the search bar and you'll get a bunch of results.
Perhaps it starts as a misunderstanding. Percy might misinterpret something Nico does as a threat to his friends. Thalia, being Percy's friend, jumps in to defend him. Nico, feeling attacked unjustly, then retaliates. It could turn into a full - on fight with them using their powers. Percy with his water - based powers, Thalia with her lightning, and Nico with his control over the dead. The fight could be a very intense and action - packed scene in the fanfic.
