Another theme is growth. After his mom's death, Percy often has to grow up faster and become more independent. Fanfics might show him taking on more responsibilities and maturing in ways he wouldn't have if his mom was still alive. For example, he may become more decisive in battles or in dealing with other challenges. In some fanfics, there's also the theme of legacy. Percy might discover things about his mom that she left behind for him, like a hidden power or a special message. This gives him something to hold on to and also adds to the idea that his mom's influence still lives on even though she's gone.
Isolation can also be a theme. Percy may feel alone without his mom, and the fanfic could explore how he either overcomes that feeling or succumbs to it. Sometimes, his friends may not fully understand what he's going through, and he has to find his own way to deal with the loss while still being part of the group. This creates a sense of both connection and disconnection in the story.
Rebuilding is also a theme. After Percy's death, the world around the characters might be in chaos. So, in many fanfictions, they have to work towards rebuilding what was lost, whether it's a physical place or the sense of hope that Percy once brought.
Percy might become more independent. Without his mom's presence, he has to rely more on himself. He could start to take on more leadership roles within the demigod community. He also may develop a darker side to his personality, as the pain of his mom's death lingers. However, through his experiences and the support of his friends, he gradually learns to balance this new, harsher side with his original kind - hearted nature.
A big theme is the re - imagining of Percy's powers. Instead of having Poseidon - like powers, he might have abilities more in line with Athena, such as enhanced mental abilities or the power to manipulate knowledge. There's also the theme of Percy's place within the Camp Half - Blood hierarchy. Since Athena is a major goddess, his status might be elevated or at least different, and this is often explored in these fanfictions.
One common theme is the exploration of Percy's new powers or abilities. Since Artemis has her own set of powers, Percy might gain some of those, like enhanced archery skills or a closer bond with nature. Another theme could be the change in Percy's relationships. His relationship with his friends and other gods would be different because of his new mom.
Grief is a very common theme. Since Catra dies, the other characters often have to deal with the pain and loss. They might go through stages of denial, anger, etc.
A common theme is grief. When Armin dies, the other characters have to deal with the intense pain of losing him. Another theme is the idea of sacrifice. His death might be seen as a sacrifice for a greater good.
Reflection is also a common theme. The characters may reflect on their time with Bones, their unsaid words, and the things they could have done differently. This often leads to character growth in the fanfic. Also, the theme of acceptance is there. The characters gradually accept Bones' death and move forward in their lives, though the memory of Bones always remains with them.
Love still remains a strong theme, but it might be a more complex and often tortured form of love compared to the original story. Another theme is survival. In 'Twilight Dies', characters are faced with new challenges and they have to fight to survive in a changed world.
The theme of legacy is also quite common. Percy's death leaves behind a legacy that the other characters have to uphold. They have to carry on his mission of protecting Olympus and also keep his memory alive. There's also often a theme of grief and how the characters deal with the loss of someone so important.
One 'percy's mom dies fanfic' that might be touching is 'A Mother's Legacy'. It delves deep into Percy's grief and how he copes with the loss, showing his journey of self - discovery after such a tragic event.
