What are some possible adventures that Percy and Steve could have in a fanfiction about their friendship?

He could encounter rare mythical creatures that are only found in the deepest parts of the wild. For example, he might come across a group of centaurs who have a different culture compared to those he met before. These centaurs could teach him new survival skills and ancient lore.

They could have an adventure in an ancient, forgotten temple. Maybe they are on a quest to find a lost artifact that could save their world. Along the way, they use Percy's water powers and Annabeth's strategic mind to overcome various traps and monsters.

They could explore ancient ruins. Maybe they find a hidden cave filled with rare Pokémon. Ash's battle skills and Lillie's knowledge of Pokémon lore would come in handy.

In some fanfictions, Percy might use his friendship with Apollo to get some unique items. For instance, Apollo could give him a special arrow that can travel through water without getting wet, which Percy could use in his future battles or quests.

One possibility is that he discovers an ancient, hidden grove that has a powerful magical spring. This spring could have the ability to heal any wound or grant temporary superhuman strength. Percy would then have to protect this grove from other forces that might want to use it for evil purposes.

One possible adventure could be in the Underworld. Percy had some experience there already, and Artemis, with her fearless nature, accompanied him. They went to rescue a lost soul that was important to both of them. Along the way, they had to face the challenges of the Underworld, like getting past Cerberus and dealing with the tricky spirits that tried to deceive them. Their friendship was tested as they made their way through the dark and dangerous realm.

One possibility is that Naruto stumbles upon a hidden village in the wild that has been cut off from the rest of the ninja world for centuries. He has to learn their unique culture and way of life. This experience could shape his view of the ninja world in a new way. He might also find a powerful and mysterious mentor in the wild who teaches him skills that are different from what he would learn in Konoha, such as how to use natural elements in a more primal and instinctive way.

One possible adventure could be them getting involved in a local Pokémon festival. They might participate in contests or help organize events. Ash could show off his battle skills in friendly exhibitions, while Lillie could share her knowledge about Pokémon care with the festival - goers.

In the fanfiction, they could also be on a quest to retrieve a powerful ancient Greek artifact. This artifact could be something like the Helm of Darkness that has been lost for centuries. Along the way, they would face many challenges. They would have to interact with the gods and goddesses of Ancient Greece, who might not all be friendly. Percy and Annabeth would rely on their friendship and unique skills to overcome all the obstacles in their path.

Well, he might face new monsters. For example, some ancient and more powerful versions of the ones he's already fought. Maybe there are new quests waiting for him at the camp, like finding a lost artifact that has the power to either save or destroy the camp.
