Water Hazard is the Omnitrix's DNA sample of an Orishan from the planet Kiusana in the Andromeda Galaxy.


Water Hazard appears as a red, mollusk-like alien. His eyes are green, and his mouth does not move when he speaks. Behind his legs and on the top of his arms are small spikes that are grey. On his shoulders and legs, there are black spots. On his hands, there are portholes, which he uses to shoot water. Water Hazard has four fingers with claws on them and on each one of his feet, there is a grey spike. His lower torso is grey, with two spikes on the side of them.

In Omniverse, Water Hazard now has four slitted eyes, and also has eyes on his chest, with crab-like features on his stomach which appear to be crab legs forming a rib cage. His hood looks a lot rougher than before, and he now has what appear to be barnacles on his shoulders, arms, legs, and hands (where he shoots the water). He also has three spikes on the back of his legs and seems to have cracks on his arms and shoulders. His fingers are sharper and represent dactyls (the "moveable finger" of a crab claw). His overall armor is a darker shade of red and his grey parts are now a violet shade of grey.

He wears the Ultimatrix/Omnitrix symbol on his chest.

Powers and Abilities

  • Water Blasts
  • Retractable Visor
  • Flight via Propulsion
  • Moisture Absorption
  • Water Whips

Water Hazard has an armored exoskeleton which protects his body from damage, including radiation. Ultimate Aggregor once commented that this exoskeleton makes Water Hazard completely invulnerable, although this has been confirmed to be not true. He also has enhanced strength,[2] seen when he threw Buglizard into a nearby wall. He also has a retractable visor hidden under his hood.[3]

Water Hazard can absorb moisture, including from the air, through the portholes in his hands.[4] He can also launch pressurized water blasts from these same holes. Water Hazard is also capable of manipulating other sources of water, such as normal water.[DM 1] He can also change the temperature of his water powers, from hot to cold, and can produce sharp streams of water and use them as whips.

Water Hazard can breathe underwater.[DM 2]

Water Hazard normally blasts hot water.[5]

Water Hazard can jump exceptionally high.[6]


Although Water Hazard's armored exoskeleton allows him to feel little to no physical pain, he seems to be vulnerable to energy attacks as well as intense heat.


  • In Fame, Water Hazard's DNA was sampled and put in the Codon Stream by sampling Bivalvan's DNA.
  • Water Hazard first appeared in Too Hot to Handle. Water Hazard pretended to be Bivalvan to convince P'andor to go home, but failed and was defeated by P'andor.
  • In Hero Time, Water Hazard defeated Overlord by blasting his super-heated armor with water making it brittle and absorbing the water back into himself sucking away the energy.
  • In Revenge of the Swarm, Water Hazard confronted some Victor clones, but they escaped.
  • In Double or Nothing, Water Hazard defeated the Methanosian actor, Swamps.

Water Hazard in Cosmic Destruction

Ben 10 Ultimate Alien: Cosmic Destruction

Water Hazard is one of the Andromeda Galaxy aliens playable in the game.

Water Hazard could generate a water tornado, briefly levitating while launching water blasts, and he wielded a water-whip to destroy enemies.

It can be seen that his mouth can open, as he opens it while firing his water cannon, and it opens and shuts when he is idle.

  • Water Hazard is the first Andromeda alien form Ben scanned and used.

    • When Water Hazard first appeared in Too Hot to Handle, his voice sounded exactly like Bivalvan's.
    • Starting in Hero Time, his voice became deeper. The reason for this is that at first Water Hazard was supposed to be a clone of Bivalvan, but later changed to help differ him from Bivalvan.[DM 1]
    • In Omniverse, his voice is slightly modified to sound like that of an underwater human.
  • In Too Hot to Handle, Water Hazard's water was colored aqua green. In the rest of his appearances, it is colored blue like normal earth water.
