One way it could work is that the spider powers could enhance his already existing skills. His reflexes, which are good from his demigod training, could be super - boosted by the spider - sense. And he could use his spider - like climbing ability to scale the walls of Mount Olympus or other mythical places that are otherwise hard to reach. This would give him an edge in battles against both mythical creatures and other demigods.
In a fanfiction scenario where Percy has spider powers, it could also change his relationships. His friends might be both amazed and a bit worried at first. Annabeth could be intrigued by how these new powers fit into their quests. And Percy himself would have to learn to control these powers, which could be a whole new adventure. He might start to see the world in a different way, noticing things that he didn't before, like a spider does with its multiple eyes. He could use this new perception to find hidden clues or threats during their adventures.
In fanfiction, the powers of the Percy Jackson characters can sometimes be combined with Assassin's Creed technology. For example, a demigod with the power of invisibility could use it in conjunction with an Assassin's stealth cloak to become almost undetectable. The healing powers of some demigods could be used to quickly heal injured Assassins after a battle. This creates a really interesting dynamic where the two different power systems complement each other and create new possibilities for the story.
His power over water could be used in various ways. For example, he could put out magical fires in the castle easily. And if there was a flood in Hogwarts, he could control it and save the day.
In the context of Jurassic fanfiction, Percy's water - based powers could be both a defense and a tool for exploration. He could use water currents to quickly move around the park, avoiding the dinosaurs. His power to heal himself with water could also come in handy if he got injured during an encounter. Additionally, he could manipulate water to create distractions for the dinosaurs. For example, he could make a large water splash to startle a group of Velociraptors, giving him time to escape. His powers would give him an edge in this prehistoric and dangerous environment.
Well, Percy's powers in Siberia would be both a strength and a liability. His ability to control water gives him an edge as there is water in different forms in Siberia, like snow and ice. However, the cold could potentially freeze his powers if he's not careful. But he could also learn to use the cold to his advantage. For instance, he could freeze his enemies in place by quickly freezing the water around them. And if he's near a large body of water like a frozen lake, he could break the ice and cause chaos among his foes by creating waves and whirlpools even in the icy water.
If Percy had ice powers in fanfiction, it might also affect his relationships. His friends would see him in a new light, perhaps with a bit of awe or even some jealousy. He could use his ice powers for fun, like creating ice sculptures during downtime at Camp Half - Blood. This would add a new dimension to his character and the overall atmosphere of the story.
One way it could work is if Naruto's immortality was a result of some powerful magic in the Percy Jackson universe. Maybe he was blessed by a god or came into contact with a magical artifact that made him immortal. His ninja skills would be quite unique in that world and could make for some interesting storylines, like teaching demigods his stealth techniques.
Well, in fanfiction, anything can be made to work. If Percy were Aphrodite's husband, it could lead to some really interesting power dynamics. Percy is a powerful demigod with his own set of skills and Aphrodite is the goddess of love. Maybe their union could bring a new kind of peace in the world of the gods and demigods. His skills in combat and her ability to manipulate emotions could combine in unexpected ways.
The storyline could involve Percy discovering these new spider powers in a strange way. Maybe he gets bitten by a mythical spider during one of his quests. Then he has to figure out how to use them without losing control. For example, he might accidentally shoot webs all over his room at Camp Half - Blood.
Their combined powers could work in various ways. Since Percy has a connection to the gods and can communicate with sea creatures, he could call upon them for help. Harry, with his magic, could then enhance the abilities of those creatures. For example, he could use a spell to make a hippocampus (a sea - horse - like creature in Percy's world) fly faster or have stronger attacks. This way, they are using both their demigod and wizard powers in harmony.
They are often portrayed as more versatile. For instance, a character might be able to turn water into ice sculptures that can come to life and fight for them. This is a step beyond what we see in the original books in most cases.
