Annabeth might find him. She's always been close to Percy and they often go on adventures together. So it's likely that she'd be the one to come across him when he faints.
It could also be a new character introduced in the fanfic. Maybe a young demigod who was lost in the same area where Percy fainted and stumbles upon him. This new character could then play an important role in the story from that point on, either by helping Percy recover or by getting involved in some sort of adventure that Percy was about to embark on before he fainted.
It could be due to some sort of poison or magical spell. In the Percy Jackson universe, there are all kinds of creatures and magic that could cause such a reaction. For example, if he was exposed to a slow - acting venom from a mythical beast, it might gradually make him faint.
To add drama. When Percy faints, it creates a moment of high tension. His friends or allies are then left to deal with the situation, which can lead to all sorts of interesting plot developments.
In a particular 'Percy Jackson faints' fanfiction, Percy faints after being poisoned by a strange and rare plant in the Underworld. His friends then have to race against time to find an antidote. This creates a lot of tension and drama as they search through different realms and face various challenges to save Percy.
In some fanfiction, Dumbledore could be near when Harry faints. He has a sort of sixth sense about Harry and often shows up at crucial moments. Luna Lovegood might also be in the vicinity. She has a unique perspective on magic and could offer some off - the - wall but potentially useful ideas for helping Harry after he faints.
In some fanfics, Nico di Angelo could be the one to help Percy. Since Nico has a connection to the Underworld and has some dark powers, he might be able to enter Tartarus more easily than others. He could use his powers to fend off the monsters and guide Percy to safety.
He might meet other inter - galactic beings. For example, some sort of space - faring demigods from a far - off galaxy. Or he could encounter powerful entities that are the rulers of other planets.

His friends like Pikachu would be very worried. Pikachu would probably stay by Ash's side, trying to use its electric shocks gently to revive him. Misty might scold Ash for being so reckless but also show concern by getting water to cool him down. Brock would immediately start checking Ash's vital signs and try to figure out what went wrong.
He could meet other demigods from different pantheons. Since it's a different world, there might be demigods associated with gods that Percy has never heard of before.
