Cupid's powers could be portrayed as more limited in a fanfiction. For example, instead of his arrows working on everyone, they only work on certain types of demigods. Or his powers could be tied to specific emotions other than just love, like a sense of loyalty or friendship. This would change how he interacts with Percy and the other characters in the story.
Cupid's powers could be shown as being able to transfer emotions between characters. In a Percy Jackson fanfiction, he could transfer Percy's courage to another character and in return, that character's love for someone else is transferred to Percy. This would be a really unique way to play with his powers and create a whole new set of storylines. Also, his powers could be made more physical, like instead of just an arrow of love, it could be a blast of energy that changes the emotional state of those it hits, which would add a more action - oriented aspect to the fanfiction.
One way to portray Cupid's powers differently is to make them more unpredictable. So, instead of his arrows having a straightforward effect of making someone fall in love, they could cause a range of emotions related to love, such as jealousy or obsession. In the context of Percy Jackson, this could lead to all sorts of interesting situations. For instance, if Percy is hit by one of these 'unpredictable' arrows, he might become overly jealous of Annabeth's friendships with other demigods, creating conflict in their relationship.
One way to portray Percy's family differently in fanfiction is to give them more power. For example, Sally could be a powerful seer like Rachel. This would change how Percy interacts with his mom as she could foresee some of his future battles and give him advice based on her visions. Another way is to make Paul more of a fighter. He could have some hidden combat skills and help Percy in his battles against monsters.
The children of Ares might see Percy as a threat. Since Cupid represents love and Ares represents war, their natures are quite opposite. The Ares kids could be jealous of Percy's powers or simply not trust him because of his different lineage.
They are often portrayed as more powerful. Writers like to make Percy's lightning powers stronger to create more intense battle scenes. For example, he can send bolts of lightning that can split mountains.
Well, in some fanfictions, Percy's fire powers are a secret at first. He has to hide them from his friends and enemies alike. This secrecy can create a lot of tension in the story. As he tries to figure out where these powers came from and how to use them properly, he might face challenges from other demigods who sense this new and strange power within him.
In many fanfictions, Percy's powers might be explored in new ways in relation to Luke. For example, how his control over water could be used to counter Luke's actions. Luke may be given different abilities or backstories that make him more of a three - dimensional character. He could be shown as having been influenced by external forces that made him turn bad, rather than just being a 'born villain' as some might view him in the original. This changes how the two characters interact and how the story unfolds.
Percy is often shown as a more free - spirited character in fanfic. His actions are driven by his emotions and his loyalty to his friends. Jason, in contrast, is usually depicted as more duty - bound. He follows the rules and traditions of the Roman camp more strictly. So in fanfictions, Percy might break a few rules to do what he thinks is right, while Jason would think twice before going against the established order.
They are often portrayed as more versatile. For instance, a character might be able to turn water into ice sculptures that can come to life and fight for them. This is a step beyond what we see in the original books in most cases.
Some fanfictions may emphasize Percy's heroism in terms of his strategic thinking. He could be devising elaborate plans to outwit the villains, using his knowledge of the mythological world. Other stories might show his heroism as a result of his empathy. He understands the pain of other characters, whether they are mortals or demigods, and tries to help them. For instance, he might help a mortal town that is being haunted by a minor god. There are also fanfictions where his heroism is about his ability to bridge the gap between different groups, like the gods and the demigods, which is quite unique.
One idea could be Percy discovering new powers related to his heritage as Cupid's son. For example, he might have the ability to manipulate emotions on a grander scale, not just in terms of love. Another could be Percy getting involved in a conflict between the children of Cupid and other demigods who are suspicious of his newfound abilities.
A really interesting plot could be that Cupid, for some reason, decides to make Percy the ultimate symbol of love in the demigod world. Percy is then thrust into a role he doesn't understand, having to deal with love - sick demigods coming to him for advice. Meanwhile, he has his own relationship problems, like his feelings for Annabeth being complicated by this new status. He has to figure out how to handle Cupid's meddling and restore some normalcy to the love lives of those around him.
