|Voice Actor||Dee Bradley Baker|
|First Appearance||Too Hot To Handle|
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 port holes, which he uses to shoot water. Water Hazard has 4 fingers with claws on them and on each one of his feet, there is a grey spike. His lower torso is grey, with 2 spikes on the side of them. When Water Hazard first appeared, his voice sounded exactly like Bivalvan. However, in his second appearance, his voice is deeper, according to Dwayne McDuffie the reason for this is that at first Water Hazard was suppose to be a clone of Bivalvan, but later changed to help differ him from Bivalvan.
In Omniverse, Water Hazard now has 4 slitted eyes, as well as eyes on his chest and crab-like legs on his torso. His hood is rougher and not as smooth and he has what appears to be barnacles on his shoulders and legs. His hood also has a retractable visor.
Powers and Abilities
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 and has retractable visor hidden within his hood. In Too Hot To Handle, Water Hazard's water is aqua green in color, but later in Hero Time, it is blue.
Water Hazard can absorb moisture, including from the air, through the portholes in his hands. He can also launch pressurized water blasts from these same holes.
Alien of the Month claims that Water Hazard blasts hot water.
According to Dwayne, Water Hazard is able to manipulate water and even mold it into a wide variety of shapes.
In Cosmic Destruction, Water Hazard could generate a water tornado, briefly levitating while launching water blasts, and he wielded a water-whip to destroy enemies.
In the online game Ben 10: Game Creator, he was able to create a bubble shield to protect himself from lasers.
In the online Cartoon Network game, Omniverse Collection, Water Hazard shoots blobs of water in an upward tilted angle, instead of just spraying it.
Although Water Hazard's armored exoskeleton allows him to feel little to no physical pain, he seems to be vulnerable to energy attacks.
