Sure. One example could be Percy taming a wild and magical beast that no one else could. Another might be him using his unique powers to save a group of people from a dangerous natural disaster within the fanfiction world.
In some fanfiction, Percy is able to break through powerful magical barriers. His strength, combined with his ability to manipulate water, allows him to find weak points in the barriers. He then uses a concentrated stream of water, supercharged with his own energy, to shatter the barriers. Also, he may be depicted as being able to revive a dying land. By using his powers to bring water to dry and barren areas, he restores life and fertility, which is a very powerful feat indeed.
Sure. In some fanfictions, Naruto can create entire new worlds just by a thought. He might be able to resurrect all the fallen characters without any cost or consequence.
In some cases, Percy might be protective in more emotional ways. If someone were to say something mean or critical about Annabeth in the fanfiction, Percy would be quick to defend her. He would stand up for her and not let anyone undermine her confidence or abilities.
There could be a moment where Percy stands up to an unjust authority figure in the fanfiction world. He defies them with such confidence and charisma that it makes him seem like a total badass. Or perhaps he dives into a dangerous, unknown realm to save someone, showing his fearless and selfless side which is very badass.
Sure. In some fanfictions, Percy can create water - based constructs like giant water golems to fight for him. He can also use water to heal himself and others at a much faster rate than in the original story.
In some fanfictions, Percy might list his feats such as slaying powerful monsters. For example, if there are new and terrifying creatures in the fan - made world, his success in defeating them would be a great feat. He could also list his feats in terms of relationships, like mending broken alliances or forging new ones that help in the overall plot of the fanfiction.
One example could be that Nico is being chased by some vengeful spirits from the Underworld. Percy uses his powers over water to create a barrier between Nico and the spirits, protecting him. Another could be when Nico is in a fight with some demigods who misunderstand him, and Percy jumps in to defend Nico and explain his situation to the others.
Perhaps in this hybrid fanfiction, Percy's character is a blend of different personalities. He could have the heroic and brave side that he is known for, but also have a more comical or clumsy side added in. In terms of plot, it could be a mixture of a coming - of - age story with a political intrigue plot. So Percy is not only growing up and finding himself, but also getting involved in power struggles and court politics within the fictional world. Also, it could have elements of different mythologies. For example, if Percy is from a Greek - mythology - based story, some Norse mythology elements could be added like Thor's hammer making an appearance in Percy's world.
Sure. There could be scenes where Percy is wearing a beautiful dress, which is a very obvious sign of femininity. Another example might be that Percy is shown to be more interested in typically female - dominated activities like embroidery or flower - arranging.
I'm not sure of specific examples off - hand. But it could be a story where Percy is constantly getting defeated in battles he used to win easily, thus showing his weakness. And his broken state could be shown through his self - doubt and lack of motivation.
