Who could be the main antagonists in 'percy is thrown into tartarus fanfiction'?

The Titans or Giants that were banished to Tartarus could be the main antagonists. They might see Percy as a threat or an opportunity to escape and seek revenge on the Olympians.

There could also be a group of demigods who are jealous of Percy's power due to his unique parentage. They might form an alliance against him, trying to steal his powers or at least make his life difficult. They could be led by a demigod who has a grudge against Percy or is power - hungry.

His friends like Annabeth or Grover could be the ones to rescue him. They might discover a way into Tartarus and brave all the dangers to get to Percy.

The monsters native to Tartarus could also be antagonists. These could be huge, grotesque creatures that have never seen the outside world. They might attack Percy on sight, seeing him as prey. Some of them could be powerful enough to even give Percy a hard time, especially if his powers are weakened in Tartarus.

Some of the more powerful and vengeful spirits in Tartarus could be the main antagonists. These spirits could possess demigods or mortals close to Percy to get to him. They might be angry that he escaped their domain and want to drag him back. Additionally, there could be a group of rogue demigods who believe that Percy has been corrupted by Tartarus and they see it as their duty to stop him, even if it means becoming his enemies.

Perhaps there's a new villain, a powerful sorcerer who has a vendetta against Percy. The sorcerer discovers that Percy is now at high school and decides to target the school. He uses his magic to create illusions and manipulate the minds of the students and faculty, turning them against Percy. The sorcerer might also be after the secrets Percy learned in Tartarus, thinking it can give him more power.

In the fanfiction, the environment of Tartarus itself could be considered an antagonist. The extreme heat, the toxic gases, and the ever - present danger of falling into bottomless pits. And on top of that, there could be some sort of demon - like creatures that are specifically created or summoned to hunt down Percy and Zoe and prevent them from achieving their goals.

It's also possible that there could be a new, unknown force in Tartarus that has been awakened by Percy's presence. This new entity could be extremely powerful and oppose Percy at every turn. It might be some sort of ancient, primordial being that has its own motives for not wanting Percy to succeed in whatever his mission in Tartarus is.

One possible plot could be Percy's struggle to survive in Tartarus. He might have to face the various terrifying monsters there, like the giants or the powerful demons. Maybe he'd find some unexpected allies among the damned souls, and together they'd try to find a way out.

Survival is a big one. Tartarus is a very hostile place, so Percy has to fight to stay alive. Another theme is redemption in some cases, like if he feels responsible for getting thrown in there.
