Well, Percy's power over water from Poseidon and the wisdom and strategic thinking from Athena could lead to some amazing combinations. For instance, he could use water to create illusions, like mirages in a desert, but with a strategic twist. He could make the illusions in a way that confounds enemies and leads them into traps that he has planned out using Athena - like intelligence.
Maybe he could use water currents to carry messages or signals in a very strategic way. Since Athena is associated with knowledge and communication, Percy could manipulate water to form symbols or words that only those with the right knowledge (like the children of Athena) could decipher. This would be a very unique way of combining their powers for both communication and secrecy.
Well, Poseidon controls the seas and Athena is the goddess of wisdom. Their powers could be combined in a story where they need to outwit an enemy that is attacking from the sea. Athena could use her wisdom to strategize a defense, and Poseidon could use his sea - related powers to execute the plan, like creating powerful tidal waves to destroy enemy ships while Athena guides the waves to the right targets.
Percy's powers would be more complex. He could have the ability to communicate with sea deities in a different way. Maybe he could use Hera's diplomatic skills to make deals with them or resolve disputes. His control over water could also be extended to other substances that have a connection to water, like steam or ice, in a more efficient way than before. And his powers of persuasion, which could be influenced by Hera, might be used to calm angry sea storms or make sea monsters cooperate with him, which is an interesting combination of his Poseidon - given powers and Hera - influenced skills.
His character would likely be a blend of Athena's wisdom and Poseidon's boldness. He'd be more calculating in his actions, thinking several steps ahead like Athena, but also not afraid to take risks when necessary, similar to Poseidon. He might have a natural inclination towards both strategy and brute force, which could make him a very unpredictable and powerful character.
In a fanfiction where Percy is the son of Hades and Poseidon, his powers would be truly extraordinary. He could have the ability to create portals in water that lead to the Underworld. This would give him an advantage in both battle and travel. His hydrokinesis could be tainted with the essence of death, so when he attacks with water, it could cause a draining effect on his opponents, sapping their life force. Additionally, he might be able to sense the presence of the dead in any water source, which could be used for both reconnaissance and protection.
Well, if Percy was the son of Loki and Poseidon in fanfiction, his powers would be a really wild mix. He might have Poseidon's control over water, but with a Loki - like trickster twist. For example, he could create illusions in the water, making it seem like there are sea monsters when there are none to deceive his enemies. He could also use Loki's shape - shifting ability while in the water, perhaps turning into a mermaid - like form with a mischievous glint in his eyes. His power over water could also be used in more devious ways, like creating whirlpools that suck in his foes and then spit them out in a different location, all while laughing like Loki would.
Another plot could involve Percy discovering a hidden connection between Poseidon and Athena that was long forgotten. This could lead to a situation where he has to convince the other demigods that this connection is important for the future of the camp. Maybe there are ancient prophecies that only he can understand due to his unique parentage.
His powers would be a blend of two very different deities. While still having control over water like the original Percy, he might be able to use his Aphrodite - related powers in combat. For example, he could use his charm to disorient opponents or make them more vulnerable. Also, his connection to the sea might be different. Instead of just controlling the water, he could perhaps make the sea seem more alluring or beautiful, which could be a new form of defense or attack, luring enemies into a false sense of security.
His powers might include the ability to control the weather like Zeus. So he could summon thunderstorms or clear skies at will. From Leto, he could inherit a connection to the moon. This might give him enhanced senses during the night or the ability to draw power from moonlight. He could also have some form of protection or blessing related to his mother's association with motherhood and fertility in mythology.
His relationships with other demigods would be very complex. For example, the children of Poseidon might see him as an oddity at first. They are used to their own set of powers and Percy having Athena's influence could make them a bit wary. On the other hand, the children of Athena might be skeptical of his loyalty as he also has Poseidon as a father. However, some demigods might be in awe of his unique heritage and look up to him, hoping to learn from his dual nature.
His powers could develop in a very unique way. Since he has the blood of Chaos, his powers might start off as small, random bursts of energy. For example, he might accidentally create small pockets of chaotic space. As he learns to control his Poseidon powers, like controlling water, he could start to merge the two. He might be able to make the water act in chaotic ways, like creating whirlpools that have unpredictable movements.
