Water Hazard is the Omnitrix's DNA sample of an Orishan from the planet Kiusana[merch 1] in the Andromeda Galaxy.


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

In Omniverse, Water Hazard now has four slitted eyes, and also has eye-like patterns 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.

Water Hazard wears the Ultimatrix/Omnitrix symbol on his chest.

Powers and Abilities

  • Hydrokinesis/Enhanced Jumping
  • Water Manipulation
  • Hydrokinetic Flight
  • Moisture Absorption
  • Water Whips
  • Retractable Visor
  • Strong Exoskeleton
  • Gas Immunity
  • Enhanced Strength

Water Hazard can launch pressurized blasts of water through the portholes in his hands. These blasts normally consist of hot water,[1] though he can change the temperature of his water powers from hot to cold. Using these same portholes, he can absorb moisture, including from the air.[2]

Water Hazard is extremely durable, as he has an armored exoskeleton that protects his body from damage, including physical attacks, thereby making him completely invulnerable.[3][4]

Water Hazard has enhanced strength, as seen when he threw Buglizard into a nearby wall and punch craters into a concrete floor. He is also shown to be immune to gases, as he was unharmed by Buglizard's yellow spray.[5]

Similar to XLR8, Water Hazard has a retractable visor hidden under his hood.[6] His hood is also retractable.[DJW 1]

Water Hazard can produce sharp streams of water and use them as whips.[7]

Water Hazard can jump exceptionally high.[8]

Water Hazard can breathe underwater;[DM 1] this feat was first demonstrated by Ultimate Aggregor during his visit to Piscciss.[9]

Water Hazard can manipulate different sources of water, including normal Earth water,[ES 1] into a variety of shapes.[8]


  • Slippery Surfaces
  • Vulnerability to Energy Attacks
  • Immobilized by Ice

Water Hazard can slip on certain surfaces, such as a Polymorph's goo.[10]

Although Water Hazard's armored exoskeleton allows him to feel little to no physical pain, he seems to instead be vulnerable to energy attacks and intense heat, such as that generated by a Prypiatosian-B.[11][12]

Water Hazard can be frozen by a Necrofriggian's ice breath.[13] Similarly, he can be ensnared by an Evolved Arachnichimp's webs, as demonstrated with Bivalvan.[14]

Water Hazard's name comes from the term "fire hazard" which refers to an action which may cause a fire and water which refers to Water Hazard's water-based abilities. It is also due to the fact that fire is widely considered the opposite to water, which makes his name ironic.


  • Each of Ben's Andromeda alien forms control a basic element. As his name suggests, Water Hazard commands water.
  • Water Hazard is the first Andromeda alien Ben has scanned and used.
  • Water Hazard's voice has changed a few times over the course of his appearances:
    • When Water Hazard first appeared in Too Hot to Handle, his voice sounded exactly like Bivalvan's did in Escape from Aggregor and Ultimate Aggregor.
    • 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 2]
    • 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.
  • Water Hazard's visor in Omniverse was designed by Steven Choi.[DJW 2]
  • Water Hazard was the Alien of the Month in January 2011.
  • In the mobile game, Xenodrome, his name was misspelled as "Waterhazard". This is also the case in the story books.
  • In the online games, Game Creator and Omniverse Collection, Water Hazard shoots blobs of water in an upward tilted angle instead of just spraying it. He is also able to create a bubble shield to protect himself from lasers.
