I'm not entirely sure specifically what 'percy's slave fanfiction' is about without more context. It could be a fan - created story within a particular fandom that involves a character named Percy in some sort of slavery - themed plot, but this is just speculation.
I'm not sure specifically what that particular 'fanfiction' is about as it's not a common or positive theme in the official Percy Jackson universe. Fanfiction can vary widely, but this title seems rather inappropriate and not in line with the positive and heroic themes usually associated with Percy Jackson.
One adventure could be that Percy and Aphrodite have to enter the realm of a love - hating monster. Aphrodite, being a slave, has to follow Percy's lead. Percy would rely on his own combat skills and Aphrodite's knowledge of love - based magic to defeat the monster and free the realm from its curse. It would be a test of their combined abilities and a chance for them to grow as characters in the fanfiction.
One common theme is the struggle for freedom. Percy, being a slave, constantly tries to break free from his bonds, whether they are physical or metaphorical. This struggle often involves facing powerful oppressors.
It should be removed. Such offensive and unethical content has no right to exist in the fanfiction community.
Probably not. The concept of slavery is a very serious and often dark topic. Even in a fanfiction context, it could involve themes of oppression, abuse, and inequality which are not suitable for everyone. It depends on how the author has treated the topic, but generally, it's not going to be appropriate for all.
This is a rather disturbing concept for a plot. But hypothetically, Percy could be in a situation where he is Artemis' slave and is made to perform tasks that are against his will. He might meet other characters who either help or hinder his attempts to gain freedom. But again, this is not a very positive or common type of fanfiction plot, and most fanfiction writers would probably avoid such a dark and unethical concept.
In this fanfiction, the plot might revolve around Percy's struggle as a slave of the gods. He could be used as a tool by the gods in their power games. For example, the gods might send him to retrieve powerful artifacts from dangerous places, and all the while he is trying to resist this unjust treatment and regain his freedom.
In these fanfictions, a common theme is often the struggle against fate. Artemis being in the role of a slave goes against her nature, so she may fight against this imposed status. Also, themes of loyalty can come up. Characters might be torn between their loyalty to Artemis in her new situation and their loyalty to the existing order in the Percy Jackson world.
Percy would feel a deep sense of guilt as well. He might think that he should have been there to protect her. So, he would be determined not only to free her but also to make sure whoever is responsible pays for what they've done. He would use his powers over water to his advantage, like creating distractions or using water to weaken the enemy's defenses while he tries to reach Annabeth.
Fanfiction can cover a wide range of ideas, some of which can be quite extreme or different from the source material. But the idea of Naruto being Sakura's slave in a fanfiction seems rather unappealing. It doesn't fit with the positive and growth - oriented themes of the Naruto series. Naruto is a character who is striving for recognition, friendship, and to become Hokage, not to be in a subservient role to Sakura.
