Top 20 Most Powerful Villains in One Punch Man (Ranked)

The popular web-comic turned manga series; One Punch Man, is nothing without its villains presented throughout the series. Many of them can be defeated in brief combat against the heroes, and some of them even bring comedic relief during a grave situation of the fights, which sometimes makes us forget how extremely dangerous and cunning in nature they are.

One-Punch Man is a Superhero series created by the artist named ONE; later, it was adapted as a manga in the same name, illustrated by Yusuke Murata, and serialized on Shueisha’s Weekly Shonen Jump. Its chapters are periodically compiled and published into individual tankōbon volumes. The series also has its own anime and currently has two seasons.

The villains in the One Punch Man universe have been assigned threat levels by the Hero Association, Wolf, Tiger, Demon, Dragon, and God, based on their destructive capabilities. Although often overshadowed by the Dragon-level threats, Demon-level threats are also more than qualified to hurt and even defeat the Hero Association’s highest-ranking members; some are even capable of destroying an entire city and wreak havoc.
