Love and friendship are major themes. Their romantic relationship is a central part of the percabeth short stories. It's shown through their small gestures, like when Percy gives Annabeth his jacket when she's cold. Also, friendship with their fellow demigods is important. They often work together with their friends from Camp Half - Blood in the stories, which shows loyalty and camaraderie. And of course, the theme of heroism is there as they fight against monsters and save the day.
One common theme is the test of their relationship. When kidnapped, Percy and Annabeth have to rely on each other more than ever, which shows the strength of their bond.
One common theme is adventure. Since Percy and Annabeth are from a world full of quests and battles, many fanfics have them going on new adventures together, which deepens their relationship. For example, they might face a new mythological monster and have to rely on each other.
Adventure is another one. Since Percy and Annabeth are known for their adventures in the original series, in these fanfictions, they might embark on quests underwater or on land to save their friends or their relationship. For example, they could be trying to stop an evil sea witch who is threatening their love or their families in this new mermaid - like world.
Another theme is the exploration of their individual identities. Thalia as a daughter of Zeus, Percy as a son of Poseidon, and Annabeth as a daughter of Athena all have their own strengths and insecurities. When they meet, they start to see themselves in new ways through their interactions with each other. This can be really well - developed in some of the better 'Thalia meets Percabeth' fanfictions.
Another theme is friendship development. The friends may start out as strangers to Percabeth but through their meeting, they form strong bonds. This can involve things like learning to trust each other and relying on one another in difficult situations.
One common theme is the growth of their relationship. In college, they face new challenges and experiences that either strengthen or test their bond.
One common theme is the deep emotional connection between Percy and Annabeth. Their relationship has been through so much in the original series, and in fanfics, this connection is often explored further when it comes to their more intimate moments.
A frequent theme is self - discovery. When Percy and Annabeth travel through time, they often learn more about themselves. Also, the theme of facing different versions of known enemies or challenges is common. In some fanfics, they encounter old foes in new time - based forms. There's also the theme of trying to preserve the timeline while being in it. They don't want to accidentally change things too much.
Another theme is loyalty. Their loyalty to each other is always emphasized. In many fanfics, they have to prove their loyalty in the face of various temptations or misunderstandings, which strengthens their love.
Well, jealousy is often a big theme. If Percy loves Annabeth but she doesn't love him back, he might be jealous of the people she does care about. Also, sacrifice. The character in unrequited love may sacrifice their own feelings for the sake of the other. For instance, Percy might hide his feelings to keep their friendship intact. And longing, just that constant yearning for the other person that runs through the whole story.
