Water Hazard

Water Hazard is a red, crustacean-humanoid alien from an unknown species from an unnamed planet in the Andromeda Galaxy. He premiered in Ben 10: Ultimate Alien.

Water Hazard's DNA sample was scanned from Bivalvan in the episode, Fame. He along with Armodrillo, Ampfibian, NRG, and Terraspin's species came from different planets in the Andromeda Galaxy, where they were kidnapped and separated from their families by Aggregor. Ben first uses this form in the episode Too Hot To Handle to poss as Bivalvan and convince P'andor to go home. Unfortunately, this attempt did not work, possibly do in part to P'andor having a vicious rivalry with Bivalvan when they were Aggregor's prisoners, and Ben had to use more violent methods and different aliens to send P'andor home. Water Hazard makes his video game debut on Ben 10: Alien Force Creator along with Terraspin.

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 Mc Duffie, he is also able to control water.

Trivia

 * Ben was able to trick P'andor into thinking he was Bivalvan, unfortunately, his plan to use it to get P'andor to leave Earth failed.
 * This is the first transformation in Ultimate Alien where Ben didn't obviously say the form's name, although he might have said it off-screen.
 * Each of Ben's new Andromeda alien forms control a basic element. As the name suggests, this form commands water.
 * Water Hazard is the opposite of Swampfire in many ways. Water Hazard can shoot and control water, whereas Swampfire shoots fire and controls plants. Water Hazard also has a strong and sturdy exoskeleton, while Swampfire is made of plant matter and can easily be broken, but can just as easily regenerate from such hits.
