Well, a major theme is the adaptation to new environments. When characters from Percy Jackson enter the True Blood world or vice versa, they have to adapt to the new rules, cultures and threats. There's also the theme of loyalty. Characters may have to choose between their loyalty to their original group (like the demigods in Percy Jackson) and their newfound allies in the True Blood world. This creates a lot of internal conflict and interesting storylines as they struggle to make the right decisions.
Another theme is the breakdown of relationships. Insanity can cause rifts between friends and family. In many 'Percy Jackson' True Insanity fanfictions, we see Percy's relationships with Annabeth, Grover, and others being strained. They have to deal with his unpredictable behavior and figure out how to help him without getting hurt themselves.
A common theme in Percy Jackson fanfiction is the introduction of new mythological creatures or entities. Since the original series has a rich tapestry of Greek mythology, fanfic authors often bring in more obscure or newly - imagined creatures. Also, the theme of character redemption is quite popular. This could involve a character who made mistakes in the original series getting a chance to make amends or change their ways in the fanfiction.
Love and relationships are quite prevalent in Percy Jackson fanfiction as well. This can range from Percy's romantic relationships, like his relationship with Annabeth, to more platonic relationships with his friends. There's also the theme of discovery, both self - discovery and discovery of new places or secrets in the mythological realm. Some fanfictions focus on Percy learning more about his own abilities or finding out hidden aspects of the gods' powers. Another common theme is the struggle between good and evil. Authors often create new villains or expand on existing ones, and show how Percy and his friends fight against the forces of evil.
One common theme is adventure. Just like in the original books, the fanfictions often send the characters on new quests. Another theme is friendship, as Percy and his friends' relationships are further explored. For instance, how they support each other during tough times.
Another theme is the mystery of Sally's past. Since she has some connection to the demigod world, fanfictions often explore what she might have been through before Percy was born. This could include her own encounters with gods or other demigods, which adds depth to her character.
One common theme is friendship. Despite the harem aspect, the relationships often start as friendships. Another theme is adventure. Just like in the original Percy Jackson series, the fanfictions usually involve quests and battles.
Well, in some fanfictions, it might be related to his demigod powers. Since he has a connection to the water element, blood being a liquid could potentially be manipulated in a way similar to how he controls water. Maybe he can sense the water content in blood and use his will to move or influence it.
One common theme is the exploration of Hades' character. Many fanfictions try to humanize him, showing that he's not just the 'bad guy' as he's often portrayed in the original stories. For example, they might show his love for his family in a different way.
One common theme is the exploration of wisdom. Since Athena is the goddess of wisdom, many fanfictions show Percy learning from her, like how to think more strategically in battles. For example, in some stories, Percy starts to analyze his opponents' weaknesses before attacking, which is a very Athena - like approach.
A common theme is the clash between the magical world of Percy Jackson and the spiritual/demonic world of exorcism. For example, how the demigod powers interact with the powers needed to exorcise spirits.
