Khoruan

The Khoruans are a race of cryokinetic, polar bear-like people. They are very well known for their creation of very famous structures made entirely of a very durable form of ice they've dubbed Khoruan Ice (sometimes Ice K). They have been around for a great deal of time and are the elemental enemies of the Pyronites; ergo, the two species are constantly at war on barren planets between each other. Neither species can endure life on the other's home world, though, which is why the wars take place on other planets.

Notable Khoruans

 * Iceburrgh, the Codon Stream's DNA sample of a Khoruan
 * Unknown Khoruan Friend, a Khoruan who will eventually be met in the first season of Ben 10: Ultimate Protectors

Trivia

 * Khoruan (and their homeworld Khoru) plays on "karhu," a Finnish word for "bear." Finnish was used as Finland is a cold place, and Khoruans are a very cold people.
