Who are the main antagonists that could be in a 'Percy and Jason best friends fanfiction'?

Even old enemies of the demigod world, who see Percy and Jason as threats, could be the antagonists. They might use deception and betrayal as a way to weaken the demigod forces, knowing that Percy and Jason are important figures among them.

One idea could be that Percy and Jason have to team up to save a group of demigods who are trapped in an ancient, cursed maze. They use their combined powers of water and lightning to break through the various obstacles. Another could be a story where they swap powers for a day and have to deal with the consequences. For example, Percy tries to control lightning but accidentally zaps some of their friends' hair into crazy styles, while Jason struggles to keep the water from going wild when he tries to use Percy's power.

It could be a group of mean girls in their school who are jealous of Bella and Leah's friendship. They try to spread rumors about them, like saying that Leah is only using Bella to get good grades or that Bella is trying to steal Leah's popularity. But Bella and Leah are smart enough to see through their lies and stand up to them together.

One common antagonist could be a power - hungry doctor in the hospital who sees Jason and Robin as threats to his own rise in the ranks. He might try to sabotage their work or spread false rumors about them. Another could be a business tycoon who wants to take over the General Hospital and will do anything to get rid of those who oppose him, like Jason and Robin. A third could be an ex - lover of either Jason or Robin who is jealous of their relationship and tries to break them up.

It could be an old enemy from Greek mythology that has been resurrected. For example, a powerful Titan who has a vendetta against the demigods, especially Percy and Annabeth.
