For me, the arc where Ainz tries to blend in with the human society while secretly being an undead overlord is really interesting. It creates a lot of comical and tense situations. Another interesting one is when he has to face off against powerful magic - using enemies and uses his own unique abilities to overcome them.
I think the arc about the exploration of an ancient tomb is really good. There are many traps and secrets in it, and Ainz has to use his wits and power to overcome them. Also, the arc where he tries to recruit new powerful allies among the different races is memorable. It involves a lot of negotiations and power plays.
One interesting arc could be the one where the main character faces a powerful new adversary. It really tests his strategic skills and leadership.
For me, the battle against Shalltear Bloodfallen is quite interesting. It shows the power of Ainz and the complex nature of the relationships within the world of Overlord. It's full of twists and turns.
The story arc about the Orochi Saga is really interesting. It involves many characters like Kyo and Iori coming together to face the great Orochi threat. Their rivalries have to be put aside as they fight for the greater good. Another interesting one is Terry's journey for revenge against Geese Howard which spans across multiple tournaments.
The storylines involving the different kingdoms in the new world are great too. How they respond to the sudden appearance of Ainz and his forces, like the Kingdom of Re - Estize's struggles and political intrigues, really draw the reader in.
Ainz is definitely one of the most interesting. His unique position as an undead overlord and his attempts to understand and rule the new world make him a complex character.
Well, the Dark Matter Thieves arc is quite fascinating. It introduces some really tough opponents for Saitama and the other heroes. Also, the arc where King is more in the spotlight is cool. King, despite being a normal human in terms of combat ability, manages to be a key figure in the hero world through his reputation and wits.
In the Overlord of the Universe novel, there is a plot twist where the entire universe's power structure is turned upside down. The main character, who was thought to be just a regular powerful being, is revealed to be the key to a much larger and more complex plan that spans across different dimensions. This revelation not only changes the way the other characters view him but also sets off a series of events that are full of suspense and action. It shows that the story is much more than just about a powerful individual but about the fate of the entire universe.
In the Overlord light novel, the plot point about Momonga's strategic planning to expand his territory is really interesting. He has to use his knowledge of the game mechanics and his intelligence to outwit his enemies. And the way he gradually builds his own empire, facing both internal and external threats, is full of twists and turns.
One interesting plot twist is the true nature of the NPCs in Nazarick. At first, they seem like simple game characters, but as the story unfolds, they show complex personalities and loyalties. Another is the way Ainz's actions in the new world are misinterpreted by the different races and factions. It leads to unexpected alliances and conflicts.
