In a fanfiction, Percy could discover a new aspect of his powers that is related to Poseidon's domain but in a way that no one has ever seen before. For instance, he might be able to control not just water but also the weather patterns over the ocean. When Poseidon witnesses this, he is proud of Percy's growth and evolution as a demigod. He then takes Percy on a special journey to an underwater realm that is only accessible to a select few, to further train him.
Well, it could be about Percy seeking advice from Poseidon on how to deal with a new and powerful enemy. Maybe he's facing a threat that only Poseidon's wisdom can help him overcome.
Annabeth would definitely be involved. As Percy's girlfriend, she is often by his side during his adventures. She could be the one who witnesses Poseidon's pride towards Percy and helps Percy understand the significance of it. Grover, Percy's best friend, is also likely to be there. He might provide some comical relief during the serious moments when Poseidon is showing his pride. Also, other demigods from Camp Half - Blood like Jason, Piper, and Leo could be involved. They could be in awe of Percy's new - found status with Poseidon and might interact with him differently because of it.
One possible plot could be Percy discovering his true parentage as the son of Amphitrite. He might struggle with his identity, as he has always known Poseidon as his father. This could lead to a journey of self - discovery where he has to learn about Amphitrite's powers and how they are now a part of him.
One possible plot could be Percy's struggle with his dual heritage. He might be conflicted between the gentle, love - associated nature of Aphrodite and the powerful, tempestuous nature of Poseidon. He could be an outcast among both the children of Aphrodite, who are often more focused on beauty and charm, and the children of Poseidon, who are known for their strength and connection to the sea. This internal struggle could form the basis of a great adventure as he tries to find his place in the world of demigods.
A great plot could revolve around Percy's role in the power dynamics among the gods. As the son of Hera and Poseidon, he has the potential to shift the balance. Some gods might try to use him as a pawn, while others see him as a threat. Percy would then have to navigate this complex political situation among the gods while also dealing with his own personal growth and the challenges that come with being a demigod.
In the fanfiction, Poseidon's visit to baby Percy could be a very solemn occasion. Poseidon, being a god, has to be careful as his relationship with Percy's mother is against the rules of the gods. He might come to bestow some of his godly essence on Percy, which would explain Percy's natural affinity for water. He could also be there to make sure Percy has a chance at a normal life for as long as possible, so he might use his powers to hide Percy's demigod scent from other monsters for a while.
Well, it could be about Percy learning all kinds of sea - related powers from Poseidon. Maybe Poseidon teaches him how to control the tides or communicate with sea creatures. For example, Percy might start off as a young boy who is a bit clumsy with his powers but as he grows up with Poseidon's guidance, he becomes really proficient.
Well, perhaps the plot could involve Percy being given the tail as a sign of special favor from Poseidon. He might then have to learn how to use the tail in underwater adventures, like swimming faster or having better control in the ocean currents. It could also lead to him being able to communicate more effectively with sea creatures, since he now has a more 'aquatic' form.
Well, it could be about Percy and Poseidon having some sort of adventure together. Maybe they team up to face a new threat in the mythological world. Since it's a fanfic, the author might also explore their relationship in ways not shown in the original stories, like Poseidon teaching Percy some unique powers or skills.
In this fanfiction, the plot could start with Zoe being cast out by Poseidon. Percy, being the hero he is, steps in. He first has to find Zoe as she might be in hiding or on the run. Then, he would have to fight off any pursuers. Along the way, they might develop a deeper bond as Percy helps Zoe come to terms with her new situation. Maybe they even team up to prove to Poseidon that Zoe is worthy.
