Overlord (Seasons 1–4)

Overlord is a dark fantasy isekai where the main character becomes the villain of the world but with a purpose.

The story follows Momonga, a gamer who gets trapped inside his favorite MMORPG, Yggdrasil, on its shutdown day.
Inside the game world, he awakens as Ainz Ooal Gown, an extremely powerful undead overlord with godlike abilities.

But instead of panicking, he decides to explore this new world, protect his guild’s legacy, and uncover whether other players like him are also trapped.

Across the four seasons, Ainz:

• builds an empire
  
  

• commands loyal guardians
  
  

• makes strategic alliances
  
  

• crushes nations
  
  

• and slowly becomes a legendary, feared figure
  
  

The anime mixes:

• dark world-building
  
  

• powerful magic battles
  
  

• politics and war
  
  

• intelligent strategy
  
  

• and the journey of a character balancing humanity and domination
  
  

It’s perfect for fans who love OP characters with deep, complex stories.
