There's also 'The Vampire Lord Momonga'. This fanfic focuses on Momonga's transformation into a vampire and how it affects his relationships with the other denizens of Nazarick. It has some really cool battle scenes where his vampiric powers are on full display.
The combination of the powerful Momonga and the allure of vampirism. Vampires are often associated with power, immortality, and a certain mystery. When you add Momonga's existing character traits from Overlord, it creates a really interesting blend. His strategic mind as an overlord combined with the new abilities and weaknesses of a vampire can lead to some very exciting storylines.
It could lead to all kinds of interesting adventures and plot twists. Maybe they help Momonga conquer new lands or face unexpected challenges together.
One interesting fanfiction could be about Momonga in a modern human world, facing the challenges of adapting to a completely different society. He might use his unique skills and knowledge from the game world to solve modern problems, like dealing with technology that is both fascinating and confusing to him.
To write an engaging Momonga x OC Overlord fanfiction, first, understand the characters well. Momonga is complex, so study his traits from the original work. For the OC, create a detailed backstory that can interact meaningfully with Momonga's world. For example, if the OC is a mage, think about how their magic system will fit into the Overlord universe. Also, focus on the relationship between Momonga and the OC. It could start as a wary alliance and develop into something deeper. Use vivid descriptions to bring the story to life, like describing the dark and mysterious settings of the Overlord world.
Well, the 'teacher - student' trope can be seen in some Momonga x OC fanfictions. Momonga imparts his knowledge of the Overlord world and magic to the OC. The 'opposites attract' trope is also there. For example, if Momonga is all about order and the OC is more of a free spirit. And don't forget the 'betrayal' trope. Maybe the OC is forced to betray Momonga due to some external influence, but then they try to make amends later. These tropes can add depth and interest to the fanfiction.
A particular fanfiction has a plot twist where Momonga finds out that a group of humans are actually descendants of the original creators of the game world. This revelation changes his perspective on humans and his place in the world, leading to a whole new set of adventures and challenges as he tries to figure out what this means for his future.
Typically, in Overlord vampire fanfiction, there are often elements of the vampire's immortality and thirst for blood combined with the power - hungry and hierarchical world of Overlord. The vampires usually have enhanced physical abilities like super strength and speed.
One possible main character could be a vampire hunter. This hunter might initially be after the forgotten overlord but then realizes that there are greater threats in the vampire world and teams up with the overlord. Another character could be a witch who has knowledge about the spell that made the overlord forgotten and helps him to break it.
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.
