Percy's time - controlling ability might add a lot of twists to the plot. If he can control time, he could potentially stop time to outwit his enemies. This would make battles much easier for him and his friends. Also, he could use it to relive certain moments to gain more information. For instance, if there was a mystery about an event in the past, he could go back and observe it closely, which would then drive the plot forward as he uses the new knowledge to solve current problems.
In the fanfiction, Percy's water - controlling ability might be the key to solving a mystery. Say there's a strange drought in the land, and Percy uses his power to figure out what's causing it. He might discover that there's an evil force sucking up all the water, and then he has to use his ability to fight against this force. This would not only involve his power but also his courage and intelligence, making the plot more complex and interesting.
One challenge could be the misuse of his power. If he accidentally goes too far back or forward in time, he might end up in a situation that is more dangerous than the one he was trying to avoid. For example, he could end up in a time when the monsters are even more powerful.
In this fanfiction, Naruto's time - control ability would be a game - changer for the plot. He could potentially travel to different points in time to gather knowledge and power. Maybe he'd go back to the time of the Sage of Six Paths to learn some ancient and powerful jutsu directly. This new - found knowledge and power would not only make him stronger but also shift the power balance in the Naruto universe. It could lead to new alliances and enmities as other characters react to his new abilities, and thus completely rewrite the plot in many unexpected ways.
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.
Well, it could change the plot in many ways. For example, if he absorbs the power of a powerful water deity, he might become even more dominant in water - related battles. This could make him a target for other powerful beings who see him as a threat. It could also lead to him having to learn how to control new and unexpected powers, which could cause some internal conflict as he tries to figure out his new abilities.
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).
One way could be that it's a gift from a minor god. Maybe a god associated with fire secretly blessed Percy, giving him this power.
Well, it could make the plot full of twists. For example, he might use his poison - controlling ability to defeat enemies in unexpected ways, like making the poison act as a sort of weapon that can target specific foes. This would create a lot of suspense as the other characters might not be aware of the full extent of his power.
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.
