One horror story is about a person who started using ice and quickly lost their job.

A Danny Phantom ice powers fanfiction could explore how his friends react to his new power. Sam and Tucker might be both amazed and a bit worried.

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.
In Miraculous Ladybug fanfiction, ice powers can add a whole new dimension. They might be given to a new character, perhaps a villain.

They can be portrayed as a destructive force. For instance, an Akuma - controlled character with ice powers could be freezing everything in sight, causing chaos in Paris. This makes it a huge threat for Ladybug and Chat Noir to handle.
