Percy might initially try to retaliate in a way that's typical of his character - with a bit of sass and bravado. However, as the bullying continues, he starts to doubt himself more. He wonders if there's something wrong with him that's causing Luke to be so cruel. So he goes through a range of emotions from defiance to self - pity. He also might look for ways to prove himself, not just to Luke but to everyone else at the camp who might be influenced by Luke's actions.
Percy often gets angry at first. He's not the type to just take it lying down. But he also feels a bit confused as to why Luke is being so mean. Sometimes he tries to stand up to Luke, but other times he just withdraws into himself, feeling sad and alone.
Percy might stand up for himself. He could use his own skills and strengths, like his control over water if that's part of the fanfiction's universe, to show Annabeth that he's not an easy target.
In the fanfiction, Percy could overcome bullying by finding true friends who support him. They can stand up to the bullies together. For example, if there are other kind-hearted characters, they might form a group to protect Percy and show the bullies that their actions are unacceptable.
Percy could stand up for himself. If he shows the bullies that he's not afraid, they might stop. For example, if they push him, he could push back (not in a violent way but in a firm 'I won't be pushed around' way).
He may also try to figure out what went wrong. Percy is a smart demigod, and he would likely not just accept the betrayal without trying to understand the cause. So, he might start investigating, talking to other characters who might have some insight, like the other demigods or even some minor gods who are friendly to him.
Percy would be completely devastated. He might go into a state of shock at first, unable to believe that Annabeth is really gone. Then he could become filled with rage, vowing to take revenge on whoever or whatever was responsible for her death.
Well, it depends on the specific fanfiction. Sometimes, Percy might get help from an unexpected source. He could befriend a magical creature that is also held captive by Luke and together they come up with an escape plan. He might also discover a hidden passage or weakness in Luke's lair that he can use to his advantage. Another possibility is that his friends from Camp Half - Blood somehow find out where he is and stage a rescue mission.
His dad might be initially shocked but quickly become accepting. After all, he is a god and has seen many strange things. He would probably use his power to make Percy's life easier during the transition, like providing resources or protection.
Well, in some fanfictions, a really tough scene is when Luke publicly humiliates Percy during a training session. He might mock Percy's skills or lack thereof, in front of everyone. It's so cruel because Percy is trying his best to learn and improve. And also, when Luke spreads false rumors about Percy being a coward or something similar. This causes others to look at Percy differently and makes it hard for Percy to make friends. It's just a horrible situation for Percy to be in.
Reacting to Percy Jackson fanfiction is quite an adventure. One aspect that can be really engaging is when the fanfiction delves deeper into the backstories of the minor characters. It gives them more depth and makes the whole universe feel more alive. Also, some fanfictions take a darker turn, exploring the consequences of the battles and the traumas the characters might have endured. It can be a bit different from the original series, but that's the beauty of fanfiction.
Percy could use his wits. For example, he could outsmart Luke by using his knowledge of the fanfiction world's rules or magic. He could also find allies. Maybe there are other characters who dislike Luke's bullying ways and would be willing to help Percy.
