I was going for Big Chill, but I still think I can cool you off. First, some nice cold water! Then, I'll absorb the moisture from the air!

– Water Hazard as he defeats Overlord.[1]

Water Hazard (alternatively spelled as Waterhazard)[2] 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 ribcage. He has much less black spots than normal. His mouth has a line running through it, his hood looks a lot rougher than before, is bigger, and more hexagonal than before, and he now has what appear to be barnacle-like portholes on his shoulders, arms, legs, and hands, from which he shoots the water. Rather than circular shoulders, he now has shoulders that end in shoulder pad-like armor above his arm, with much less black markings. He also has three spikes on the back of his legs and seems to have cracks on his arms and shoulders. The red sections near his face are now shorter and seemingly connect to his head with silver wire-like sections. His fingers are sharper and resemble dactyls, the "moveable finger" of a crab pincer. He is taller and thinner, as well as his legs becoming much thinner. His overall armor is a darker shade of red, seemingly maroon, and his grey parts are now more violet.

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

Powers and Abilities

Water Hazard can launch pressurized blasts of water[note 1] through the portholes in his hands. These blasts normally consist of hot water,[3] 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.[1]

Water Hazard is extremely durable, being able to withstand crashing into a wall seemingly painless.[4] He has an armored exoskeleton that protects his body from damage, including physical attacks, thereby making him completely invulnerable.[5][6]

Water Hazard has enhanced strength, enough to throw Buglizard into a nearby wall[7] and punch craters into a concrete floor.[8]

Similar to XLR8, Water Hazard has a retractable visor hidden under his hood.[9] His hood is also retractable.[DJW 1]

Water Hazard can produce sharp streams of water and use them as whips.[10]

Water Hazard can jump exceptionally high.[8]

Water Hazard can withstand radiation, such as that generated by a Prypiatosian-B.[11]

Water Hazard can breathe underwater.[DM 1]

Water Hazard can manipulate different sources of water, including normal Earth water,[ES 1][DM 2] into a variety of shapes.[8]


Being thrown can force Water Hazard to fire water blasts uncontrollably.[4]

Water Hazard is vulnerable to intense heat, such as that generated by a Prypiatosian-B.[12][11]

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]

  • 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:
  • Water Hazard was designed by Steven Choi.[DJW 2]
  • Before Water Hazard shoots water in Omniverse, the sound of a gun cocking can be heard.
  • Water Hazard was the Alien of the Month in January 2011.
  • In the Family Guy episode Quagmire and Meg, during the scene where the old man is reading to his child, you can see two toys that resemble Water Hazard and Ultimate Swampfire.
  • 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.
  • Orishan have been confirmed to be separate entities from the Cascans, another red hydrokinetic species from the Andromeda Galaxy that was introduced in the reboot. Duncan Rouleau likens the differences between these species to those between panthers and jaguars.[DR 1]
    • Duncan is a fan of both Water Hazard and Overflow for different reasons, yet prefers the latter for his simplicity.[DR 2]
    • Unlike Cascans,[DR 3] Water Hazard cannot turn water into either ice or steam.[DJW 3]
