Well, it could be about Percy facing some new and unique challenges while training in isolation. Maybe he discovers a new power within himself during this alone time. He could be training to master a new weapon or combat style, like learning to fight with a double - edged sword that has some special powers. And he might encounter some mythical creatures that are drawn to his solitary training, which he has to fight off while still trying to improve his skills.
The plot might involve Percy training alone because he feels he needs to become stronger to protect his friends. He could be in a secret location, like an abandoned temple dedicated to an ancient god. During his training, he starts having visions of the future, which show him the great threats that are coming. So he intensifies his training, trying to figure out how to use his powers in new ways, such as combining his water - based powers with his demigod strength to create a more powerful attack.
There could be some minor gods or spirits as supporting characters. For instance, a nymph that lives near Percy's training area could provide him with fresh water or food when he needs it. A small god of the forest could give Percy advice on how to use the natural elements around him for his training. And there could be an old demigod who has retired from battles and now lives near Percy's training place. He shares his old war stories with Percy, which gives Percy new ideas and motivation for his training.
Well, perhaps Percy could be learning some new and powerful combat skills from Chaos. Maybe Chaos teaches him to manipulate chaos energy in unique ways for battle.
One possible plot could be Percy learning unique survival skills while training in Alaska. Maybe he has to deal with extreme cold, wild animals like bears or wolves. He could also meet local Alaskan characters who teach him their traditional ways of living and hunting, which in turn enhance his own training.
Perhaps the fanfiction could be about Naruto training Percy in stealth. Percy, being a demigod, often charges into battle head - on. Naruto, on the other hand, is a master of stealth. He could teach Percy how to move quietly and undetected. This would be a great advantage for Percy when he has to infiltrate a monster's lair or spy on the enemy. The story could show Percy struggling at first but gradually getting better with Naruto's guidance.
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.
Percy living alone might also lead to him having a different relationship with the gods. He may become more independent from them, not relying on their occasional help. This could make the gods view him in a new light, either as a threat or as a more self - reliant and respected figure. He could start to question the gods' motives and actions more deeply, leading to some interesting confrontations or discussions.
Well, in such a fanfic, Naruto might focus on mastering a new jutsu. He could be in a secluded area, like the forest near the village. He would practice over and over, facing challenges like controlling his chakra better. Maybe he'd also be thinking about how to become stronger to protect his friends and the village.
One possibility is that Percy trains his powers with the help of his friends. They could create special scenarios or obstacles for him to overcome, which in turn helps him to develop his powers further. His powers could also start to evolve in unexpected ways during this training process.
Well, for this type of fanfiction, the plot might start with Percy being separated from his usual allies very early on. He'd be forced to navigate the mortal world by himself. Since he's growing up alone, he may not have the same understanding of his Greek heritage as he does in the original series. This could lead to him making different choices when it comes to using his powers. For example, instead of using them to protect Camp Half - Blood, he might use them to simply survive in a world that seems to be constantly against him.
Well, one possibility could be Percy facing his inner demons. In Tartarus alone, he might have to deal with the memories of his past failures and the fear that comes with being in such a desolate place. He could encounter strange and terrifying creatures that test his combat skills and his will to survive.
