Sure. In it, Percy may have the power to manipulate water on a molecular level, allowing him to create complex shapes or even turn water into a solid weapon.
He might also gain the power of seeing the past of any water - related place or object. So he could uncover hidden secrets.
Perhaps he has a power to heal others using the energy from water. It could be a really useful power in the story.
Well, in some fanfictions, Percy might have the power of enhanced underwater communication. He could talk to not just regular sea creatures but also mythical ones that are usually hard to reach. For example, he might be able to have a full - fledged conversation with a kraken.
He could start by simple things like creating ice cubes at will. Then progress to making small ice sculptures, which could later grow into larger and more complex ones. Eventually, he could learn to create ice storms or even entire ice landscapes.
One possible new power for Percy Jackson in fanfiction might be the ability to communicate with all types of mythical creatures, not just those related to the sea. This would expand his network of allies and give him more knowledge about the mythical world.
Well, in fanfiction, Percy could have the power to control storms on a global scale. Imagine him summoning massive hurricanes to defeat his enemies or using gentle rain to heal the land. It would be a huge upgrade from his existing water - based powers.
In fanfiction, Percy Jackson's lightning powers often get enhanced or modified in interesting ways. Some authors might have him control lightning in more precise forms, like creating lightning cages to trap enemies. It adds a new level of coolness to his already amazing abilities.
In the fanfiction, the power of fire manipulation could be really interesting for Percy to absorb. Since he is mainly associated with water, having the power of fire would create an internal struggle between his original element and the new one. Also, the power of teleportation would be cool. He could instantly travel to different places, which would make the story's pacing much faster and more exciting. And the power of mind - reading would give him an edge in understanding his enemies' plans and his friends' true feelings.
Percy would initially be shocked and a bit scared. But then, his sense of responsibility would kick in. He would start to train himself to use the powers effectively. He might seek out the help of some of the more benevolent gods or goddesses who could give him advice. He would also have to deal with the envy or fear of others. However, Percy's loyalty and good heart would guide him to use the powers for the greater good, like protecting the demigods and the world from new threats.
Percy's powers would be a great addition to the Avengers in a fanfiction. His control over water could create a lot of strategic opportunities. He could flood an area to slow down enemies or create ice platforms for the Avengers to stand on during battles. Compared to Captain America's leadership and combat skills, Percy could offer a different kind of support. And when it comes to Thor, while Thor controls lightning, Percy could use water to conduct that lightning in different ways for more powerful attacks.
He could gain the power of super strength that far surpasses his demigod strength. This would allow him to lift extremely heavy objects or even mountains. Another power might be the ability to control the very essence of the ocean on a global scale, not just local waters like he could as a demigod.
Perhaps he gets the power of astral projection. He could send his spirit out of his body to explore areas that are otherwise inaccessible or to spy on his enemies. This would be a very useful power especially when dealing with secretive foes or trying to find hidden places in the mythological world.
