One-Punch Man Wiki
This article is about the bonus chapter. For the disaster level threats, see Mysterious Beings (Disaster Levels).

Disaster Level (災害レベル, Saigai Reberu) is an extra chapter included with Volume 15.


After Saitama saves a street food vendor from a monster, the vendor thanks Saitama and asks about the disaster levels. Saitama simply doesn't know and instead asks for a baked potato. Shortly after, an alert is announced about a Tiger-level monster by the name of Black Roast. However, the monster is quickly disposed of by Air and the alert is called off.

Meanwhile, the Surly Brothers defeat a Demon-level monster and receive a report of a Wolf-level threat. The brothers encounter Withered Sprout, a weak looking monster that begs for mercy. Angry Man tries to kill it, but gets frozen by the monster. Soon after Crying Man and Smile Man both get frozen as well when the monster is revealed to be a dragon-level threat. Saitama later passes by and the monster uses a sneak-attack and freezes Saitama. Saitama easily breaks his glaciers, and the monster attacks him again only to be killed by Saitama's punch, for freezing his potato.

Saitama later meets Genos, who was burning a pile of monster corpses and explains he got damaged by a Demon-level monster, but Saitama was simply trying to roast his potato.
