Water Hazard is a red armored alien from the Orishan species and from an unknown planet in the Andromeda Galaxy. He first appeared in Ben 10: Ultimate Alien.

Water Hazard's DNA sample was scanned from Bivalvan in the episode, Fame. Ben first uses this form in the episode To Hot To Handle when Ben tries to convince P'andor(NRG's Genetic Copy) to leave planet earth.

Powers and Abilities

Water Hazard has an armored exoskeleton which protects his body from most types of damage, including moderate amounts of radiation. He possesses limited superhuman strength and can shoot pressurized water from openings within holes in his hands. He also appears to be at least partially amphibious. According to Dwayne McDuffie, he is also able to control and manipulate water at will and even mold it into wide variety of shapes. He can absorb
moisture from the air, as seen in Hero Time through the holes in his hands, effectively pulling a reversal on his powers. although Captain Nemesis's armor was made brittle by heat before Water Hazard broke it. Water Hazard's species can take severe damage and not feel a thing (revealed in Ultimate Aggregor as Aggregor didn't feel a thing even if a house was thrown at him.) In the Cartoon Network game Ben 10 Game Creator, it is revealed he can create a bubble shield to protect himself, even resisting laser attacks. Agreggor used this power in Perplexahedron.

He first appears in the episode Too Hot To Handle to pose as Bivalvan and convince P'andor to go home. Unfortunately, this attempt did not work, so he started trying to fight him which did not work either so he had to change aliens. He appeared again in Hero Time (first time he is named) where he powers down Overlord. He first got him wet then he absorbed the moisture from the air to make his suit shatter and then he was defeated.
