Waterhazard is the Omnitrix's DNA sample of an Orishan from the planet Kiusana in the Andromeda Galaxy, first appearing in Ben 10: Ultimate Alien.
Waterhazard 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 are portholes, which he uses to shoot water. Waterhazard also has four fingers with claws on them and a grey spike on each of his feet. His lower torso is grey with two spikes on the side of it.
