In the fanfiction, an epic battle could be against a group of rogue demigods. Percy uses his lightning control not only to fight but also to show his dominance. He strikes the ground around them with lightning, creating a perimeter that they can't cross. Then there could be a battle against an ancient deity who has awakened. Percy's lightning control is the only thing that can hold the deity at bay for a while as he figures out a way to defeat it completely.
Well, in some fanfictions, it might be related to his demigod powers. Since he has a connection to the water element, blood being a liquid could potentially be manipulated in a way similar to how he controls water. Maybe he can sense the water content in blood and use his will to move or influence it.
Well, in some fanfictions, Percy might control ice through a new power bestowed upon him by some mysterious god or entity. Maybe he discovers he has the ability during a quest when he's in a really cold and magical place.
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.
One great Percy Jackson Lightning Thief fanfiction is 'The Lost Quest'. It continues the adventures of Percy and his friends in a really engaging way, with new monsters and challenges that fit well with the original story's tone.
In this fanfiction, the control of fate might be shown in various ways. For example, Percy could be facing challenges where his pre - determined fate by the gods is being questioned. Maybe he starts to make his own choices that go against what was 'fated' for him, which is a common theme in Percy Jackson stories. This shows his growth as a character and his struggle against the powerful forces that seem to control his destiny.
Well, in some fanfictions, Percy might use his water - controlling abilities. Since poison can be in liquid form, he could manipulate the water within the poison, perhaps separating out the harmful components. Another way could be through his demigod powers, which might give him an innate resistance or control over harmful substances like poison.
Annabeth Chase would likely be one of his main allies. She's smart and resourceful, and she could help Percy figure out how to use his space - controlling powers in the best way, like strategizing how to navigate through a dangerous part of space.
Some fanfictions might suggest that Percy's control over blood is a new power he discovers while on a special quest. He might find out that his powers are not just limited to water bodies but can also extend to the fluids within living beings. He could start to experiment with this new - found ability, and at first, it might be a bit clumsy. But as he gets more practice, he could use it for various things, like healing (by manipulating the blood's flow to injured areas) or even in combat (by making an opponent's blood act in a way that disables them, like making it rush to their head and cause dizziness).
I'm a big fan of Percy in fanfictions. He's always so brave and resourceful. In many fanfictions, he gets to show even more of his humorous side, which makes him really likable.
