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 being the 'God of Ice' is a creative and non - canonical interpretation. It could be a writer's unique take on the character, perhaps giving him ice - related powers and a new role within the fan - created narrative. It might involve him having control over ice, snow, and cold elements, different from his original abilities in the official Percy Jackson series.
There could be a fanfiction where a character with ice powers is actually an enemy in the Percy Jackson world. They are trying to freeze over all the water sources, which would be a huge threat to the demigods. Percy and his friends have to figure out how to stop this ice - powered foe. They might discover that the only way is to find a way to combine fire and water powers in a unique way, like using the heat from Hephaestus - forged weapons along with Percy's water control to melt the ice and defeat the enemy.
Well, in some Percy Jackson fanfiction, there might be other characters who are made to be the master of water. Maybe a new character is introduced who has some unique ability related to water that surpasses Percy's. However, usually, Percy is the main character associated with water powers because of his heritage. He can summon water, control its currents, and even communicate with water - based creatures. So, in most cases, when we think of the master of water in Percy Jackson fanfiction, Percy comes to mind first.
There's also 'Ice Skating in Camp Half - Blood'. This one is set in the Camp Half - Blood and features the characters trying to incorporate ice skating into their training. It's a fun read as it shows how the demigods with their different powers and personalities adapt to this new form of activity.
A powerful ice giant could be the antagonist. This ice giant could have a grudge against Percy for some past encounter and uses its ice - magic to freeze him. It wants to keep Percy out of the way while it tries to invade Camp Half - Blood or other places important to the demigods.

The tagging system on AO3 makes it easy to filter out the stories you're interested in. You can look for tags like 'ice', 'Percy Jackson', and related keywords to find the fanfictions you want.
One great Percy Jackson ice fanfiction could be one where Percy uses his water powers in an icy environment in a really unique way. For example, he might create ice sculptures that come to life to help him in a battle.
He could have the power to freeze water instantly. Since he has a connection to water already as a son of Poseidon, this would be an extension of that. He might also be able to create ice storms and blizzards at will.
Another important character could be Chiron. He, as the centaur mentor, plays a crucial role in guiding Percy. He might be the one to first discover Percy's ice powers and then help him understand the implications of being the Son of Ice. There could also be villains, such as a dark wizard who wants to steal Percy's ice powers for his own evil purposes.
