Webcomic notice The following section contains Webcomic spoilers. You have been warned, manga-only readers.

Evil Natural Water (エビル天然水, Ebiru Tennensui) is a Dragon-level Mysterious Being and a member of the Monster Association.


Evil Natural Water is a huge mass of water with a pair of eyes floating inside. It can also freely change its shape.


It doesn't seem to have a brain and acts completely on instinct. It also reacts to the emotions of the people around it.


He is one of the heads of the Monster Association. He attacks Saitama but is defeated and scattered into droplets. It later reappears in a smaller form stabbing Air in the throat and being swallowed and digested by Pig God.

Abilities and PowersEdit

As a high-ranked member and a Dragon-level Mysterious Being of the Monster Association, Evil Natural Water is an extremely powerful being. As mentioned by Black Sperm (who heard it by rumour), Evil Natural Water is able to respond to other people's emotions and attack.

Physical AbilitiesEdit

Intangibility: Evil Natural Water's body is made up of water and therefore cannot be harmed by normal means, although Saitama's punches were an exception. It, however, can be scattered to many droplets, if the force used against it is powerful enough. It was only killed because of Pig God's powerful stomach acids.

High-Speed Jet Streams: Evil Natural Water is capable of firing devastating high-speed jets of water in an instant. The jets of water are about as fast as bullets, fast enough to be almost impossible to track and predict, and have a higher penetrating power.


  • "Blub Blub"

Trivia Edit

  • He is the third monster to survive one of Saitama's punches.
