Another theme is leadership. As an overlord, Percy has to lead. Fanfictions might show his decision - making processes, like how he deals with rebellions or manages resources. It's all about how he steps up to the leadership role.
One great 'Percy Jackson Overlord' fanfiction is 'The Demigod in Nazarick'. It combines the magic and adventure of Percy's world with the dark and complex setting of Overlord. Another one could be 'Percy and Ainz Ooal Gown's Alliance' which imagines an alliance between Percy and the powerful Ainz. There are also some that focus on how the demigods would react to the different races in the Overlord universe.
The theme of identity is quite prominent. When Percy enters the Overlord world, he has to re - evaluate who he is in this new context. Is he still just a demigod? Or does he become something else? And the theme of discovery is there too. Characters discover new powers, new places, and new ways of thinking as they cross over between the two universes.
Another one is 'The Overlord Percy's Allies'. This story focuses on Percy as an overlord forming alliances. It shows how he negotiates with different characters from the original Percy - related universe and how these alliances shape his rule and the story's overall direction.
One possible plot could be that Percy Jackson, with his demigod powers, somehow gets transported to the world of Overlord. He might initially be seen as a strange being by the denizens of that world. He could team up with some of the characters from Overlord to fight against a common enemy, like a new powerful dark force that threatens both his world and the Overlord world. His water - based powers would be quite unique there and could be used in creative ways during battles, for example, to put out fires in a burning city or to create barriers against enemy attacks.
Percy would likely be very curious about the characters in the Overlord world. He might approach them with his usual friendly and adventurous attitude. The Overlord characters, depending on their nature, could either be hostile or intrigued. For example, the more powerful and evil - inclined characters might see Percy as a threat and try to eliminate him. But the more neutral or good - hearted ones could be interested in learning about his powers and his world.
Maybe Percy and Albedo could embark on a journey to find a rare magical item that is said to have the power to change the balance of power in the Overlord world. Along the way, they learn about each other's cultures and powers, and their relationship deepens from mere acquaintances to close friends or even something more. For example, Percy could teach Albedo some of his combat tactics, while Albedo could introduce Percy to the complex magic system of the Overlord world.
Percy might have physical combat abilities and strategic thinking from his own background. Albedo, on the other hand, has powerful magic and knowledge of the Overlord world. Percy's combat skills can be useful in direct confrontations, while Albedo's magic can be used for long - range attacks or to create barriers. Their combined efforts can make them a formidable team.
