Well, Percy's demigod powers are very much based on his connection to Poseidon. If he becomes Doctor Fate, he might be able to channel the power of the sea into Doctor Fate's artifacts. For example, he could make the Helm of Fate have a water - like essence, allowing for different types of magical manipulations. His speed and strength, which are enhanced as a demigod, could also be used to perform more powerful magical feats as Doctor Fate.
Percy could use his water - controlling powers to manipulate the magical energies associated with Doctor Fate. Maybe he could create water - based defenses or attacks within the magical constructs of Doctor Fate's powers.
Well, he'd probably bring his own heroic style to the role of Doctor Fate. Percy is used to fighting with a sword and his demigod powers. As Doctor Fate, he might combine his water - controlling abilities with the magic of Doctor Fate's artifacts. He could make some really unique spells using his Poseidon - given powers.
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.
His water - controlling powers are super useful. He can use them to speed up the building process. For example, he can manipulate water to move heavy logs or metal parts more easily, like a natural crane. Also, if there are any problems with the ships at sea, he can use his powers to patch up holes or stabilize the vessels in rough waters.
Another power that could make a demigod the most powerful is the ability to manipulate time. In some fanfictions, a demigod might gain this power, either through a special quest or some kind of divine gift. This would allow them to stop time, rewind it, or speed it up for themselves or others. It would give them an incredible advantage in battles, as they could freeze their opponents and strike at will.
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.

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.
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.
Percy's power over water could be used in potions class. He could manipulate water elements in the potions, perhaps making it easier to create certain water - based elixirs. Also, in Defense Against the Dark Arts, his combat skills as a demigod could be combined with defensive spells. For example, he could use his sword - fighting skills along with a Shield Charm to fend off attacks.
His water - controlling powers could turn the tides, literally. He could flood enemy trenches or create barriers of water to protect Allied troops. So, it could greatly affect the outcome by giving the Allies an edge in battles near water.
