Water Hazard is the Omnitrix's DNA sample of an Orishan from the planet Kiusana in Earth-1010.


Water Hazard is a humanoid alien with a tough red exoskeleton. He has four green eyes on his head with an additional two eyes on his chest. His grey shell mask also has four green eyes on it. His body is covered in grey barnacles with green insides.

Powers and Abilities

Water Hazard can absorb moisture, including from the air, through the portholes in his hands. He can also launch pressurised water blasts from these same holes. Although he rarely demonstrates this ability, Water Hazard is capable of increasing the temperature of his water past boiling point. This allows him to blast out water or steam at the temperature of a geyser, however anything above 100oC can hurt him inside.

Water Hazard has incredible durability thanks to his tough armoured exoskeleton. He also possesses a degree of enhanced strength.


Although he is incredibly durable, he is vulnerable to energy-based attacks.


Water Hazard was originally added into the Omnitrix and Ultimatrix in the Prime Dimension (including the Prime timeline and Ultimate Ben timeline) by scanning Bivalvan while he was on Earth fleeing from Aggregor.

Death of Ben 10

Omni Apollo used his version of Water Hazard, called Aquanaut, to counter Ben 23'000 as Charcoal Man but he was still beaten.
