One common theme is identity. Since Percy has a different parentage than in the original stories, he often has to figure out who he really is. Another theme is power. Discovering his powers as the son of Pontus and Thalassa and learning to control them is often explored.
A prevalent theme is acceptance. Percy may face challenges in being accepted by the other demigods or the gods themselves because of his unique heritage. There's also the theme of family. How his new family ties to Pontus and Thalassa shape his relationships and his sense of self. For example, in some fanfictions, Percy might have to deal with the expectations that come with being the son of such powerful entities. And this can lead to all sorts of interesting storylines, like him trying to prove himself worthy or having to break away from the traditional paths set by his new family. It's really interesting to see how different authors handle these themes.
Well, I've heard about a fanfiction where Percy, as the son of Pontus and Thalassa, has to team up with some unlikely allies to face an ancient threat. It's really cool because it combines elements of Greek mythology with new and exciting twists. The author does a great job of creating a vivid world for Percy to navigate, and the action scenes are really well - written. It's a bit hard to find but if you search on some of the more niche fanfiction platforms, you might be able to locate it.
There's also a fanfic called 'The Sea's Heir: Percy'. In this story, Percy discovers his powers as the son of Thalassa are far more complex than he initially thought. It's full of action and adventure, with Percy teaming up with some unexpected allies to protect the underwater realm. The descriptions of the underwater world are really vivid and immersive.
You can try fanfiction websites like Archive of Our Own (AO3). It has a large collection of fanfictions, and you're likely to find many works related to Percy son of Thalassa there. Just use the search function and type in relevant keywords.
Well, it could be about Percy having to deal with the powers and heritage that come with being the adopted son of Pontus. Maybe he discovers new underwater abilities that are different from his Poseidon - given powers. He might also have to face enemies who are after the secrets Pontus has.
The plot could involve Percy's journey to discover the true meaning of being the son of Gaea and Pontus. He could be on a quest to find out more about his parents' realms and how they interact with the world of the demigods. Along the way, he may encounter mythical creatures that are related to Gaea and Pontus, and he has to either fight them or make peace with them. There could also be a sub - plot about Percy's relationships with his friends at Camp Half - Blood, as they struggle to accept this new side of him.
His fellow demigods could be potential allies. They might understand his struggles and be willing to fight alongside him. For example, a demigod with water - based powers could complement Percy's abilities. Also, some sea nymphs who have a connection to Pontus might offer their help. They could provide valuable information about the underwater world and its secrets.
A plot could involve Percy discovering a hidden power within him that is related to Pontus. Maybe he has the ability to control a special type of sea creature that was thought to be extinct. As he tries to master this power, he could face opposition from those who fear his new - found strength. He might also meet other demigods who are either helpful or hindering his journey of self - discovery.
One idea could be Percy discovering new powers related to being the son of Pontus. For example, he might be able to control underwater currents in ways he couldn't before. Another plot could involve him having to face a new type of sea monster that is specifically drawn to his Pontus heritage. He could also go on a quest to find an ancient artifact related to Pontus that has the power to either save or destroy the underwater world.
Perhaps an ancient sea god who was once an enemy of Pontus. This god could see Percy as a threat because of his heritage. He would use his own minions, like sea serpents and murlocs, to attack Percy and those he cares about. He might also try to corrupt Percy, tempting him with power to turn against his friends.
Perhaps Percy discovers a prophecy related to his birth. It could state that he is the key to either saving or destroying the world. This would create a lot of internal conflict for him. On one hand, he has his friends and the people he cares about in the mortal world. On the other hand, his powers and his role according to the prophecy could force him to make some very difficult choices.
