There might also be a theme of self - discovery within the context of being an overlord. The character may start to question their values and motives as they gain more power and influence in the world of the novel.
The titular worldly overlord is of course a central character. This is usually a strong - willed individual with great ambition.
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.
Power is a common theme. Many fanfictions explore how the characters gain and use power, like in 'Ainz's Ascent' where it shows his journey to greater power.
One common theme is power struggle. Clementine often finds herself in situations where she has to either gain power or fight against those with more power in the Overlord universe.
Survival is also a big theme. The characters in both Naruto and Overlord often find themselves in dangerous situations. In fanfiction, this can be intensified as the characters from one series are thrown into the other's world and have to adapt and survive in a completely new and often hostile environment.
One common theme is the power struggle. The protagonist tries to tame the evil overlord, which means there's a constant push and pull regarding who has the upper hand in terms of power and control. Another theme could be redemption. Maybe the evil overlord has a past that can be redeemed through the taming process. Also, the theme of moral ambiguity often shows up. As the protagonist gets closer to the overlord, they might start to question their own morals and whether the methods they use to tame are truly right.
The theme of discovery is quite common. The OC discovers new aspects of the Overlord world as he builds his harem. For example, he might find hidden powers or secrets. And of course, the theme of romance is always there. The relationships between the OC and the harem members are at the heart of these fanfictions, with different levels of love, affection, and sometimes jealousy playing out.
Common themes in Overlord OC Guild fanfiction include survival. The OC guild has to find ways to survive in a world full of powerful foes. Another is the theme of growth, both in terms of power level and as a group. They start from being relatively weak and grow in strength and influence. Additionally, the theme of mystery is often present, as there are always secrets to uncover in the Overlord world, and the OC guild is often at the center of these mysteries.
One common theme is power. Since Ainz is already extremely powerful as an Overlord, making him a vampire in fanfiction often amplifies that power. He might gain new abilities like enhanced strength, speed, and the power to control blood. Another theme could be the struggle with his new vampiric nature. For example, he may have to deal with the urge to drink blood while still maintaining his sense of self. Also, relationships can be a theme. His interactions with his followers might change as they react to his new form, and there could be new dynamics with other characters in the Overlord universe who either fear or try to use his vampiric powers.
Often, there are themes related to loyalty and betrayal. In a Yuri relationship in 'Overlord' fanfics, the loyalty between the two female characters can be tested. This could be due to external factors like the politics or battles in the 'Overlord' world. And when one character feels betrayed by the other, it can lead to a lot of drama and emotional turmoil, which makes for an interesting read.
