Overlord

Overlord is a fantasy action series that premiered in summer 2015, spanning thirteen episodes across a single season. The anime follows Momonga, a player who finds himself trapped in the virtual reality game Yggdrasil after its shutdown, transformed into a powerful skeletal wizard. What sets this series apart is its exploration of a protagonist who embraces villainy rather than heroism, seeking to establish dominance in a world where game mechanics have become reality and non-player characters have mysteriously gained sentience and emotion.

The show appeals to viewers interested in dark fantasy narratives with strategic gameplay elements and world-building centered on an unconventional protagonist. Overlord completed its initial run and has since expanded into multiple seasons, making it an established franchise for those discovering it now. The premise combines isekai elements with a morally ambiguous lead character navigating a transformed digital realm, offering something distinct from typical hero-centered adventure stories. This opening season establishes the foundation for Momonga's rise to power and his relationships with the surprisingly autonomous NPCs around him.
