At first, it could be quite rocky if they find out later in the story. Percy might be angry that Luke has been keeping secrets or has done bad things in the past. But eventually, they would likely grow closer as they realize they are family and start to support each other.
Luke in Percy Jackson fanfiction can play various roles. He could be a reformed villain, seeking to make amends for his past actions. This gives a new arc to his character that wasn't fully explored in the original books.
Yes, there might be such fanfictions in the vast world of fan-created content. However, it would be a rather dark and non - canonical take on the relationship between the characters, as it goes against the general narrative where they are more often allies or rivals in a less fatal way.
Well, in some fanfictions, Luke might be possessive of Percy because he sees Percy as a symbol of power or potential. He may want to control Percy to use his abilities for his own goals, like in the original story where Luke has his own dark motives. Also, it could be out of envy. Percy has things that Luke might feel he lacks, so his possessiveness could be a way to try and take what Percy has for himself.
Luke might become more enraged. Since Percy has thwarted his plan to do something to Annabeth, he could seek revenge. He might start plotting more devious schemes against Percy and Annabeth, or even their friends.
In Percabeth fanfiction, Luke's jealousy of Percy can be quite complex. Firstly, Percy has a certain 'it' factor. He's brave, but also has a sense of humor and is able to make friends easily. This makes him popular among the demigods. Luke, who has his own insecurities and a different path in life, sees Percy as someone who has it all. Percy's relationship with Annabeth is a big part of it too. Annabeth is smart, strong, and beautiful. Luke may have desired her for himself at some point. And seeing Percy with her, having her love and support, could really fuel his jealousy. Additionally, Percy seems to have a better relationship with the gods, which gives him more opportunities and power, and this is something Luke may deeply envy.
I really liked 'Luke and Percy: A New Beginning'. In this fanfic, the author imagines a scenario where Luke gets a second chance. Percy is initially skeptical but as the story progresses, they form a bond that is both unexpected and heartwarming. It's a great read for those who want to see a different side of their relationship.
I'm not sure specifically as there could be many different interpretations in different fanfictions. But generally, it might involve Luke taking actions to rescue Percy from some sort of danger, like a monster attack or a dangerous situation in the world of their story.
The theme of power is also common. Both Percy and Luke are powerful in their own ways. Fanfictions may explore how they use or misuse their power, how they compare to each other in terms of strength, and how they learn from each other's approach to power.
Sure, there are some. Fanfiction is all about exploring different relationships and scenarios that might not be in the original works. For Percy and Luke, a kiss could be a part of a story that delves into their complex relationship, perhaps a moment of unexpected connection or a turning point in a story where they see each other in a new light. Writers often use this to create unique and engaging stories.
