Arctiguana

Articguana is a blue iguana-like alien, of the species Polar Manzardill from the polar planet X'Nelli. He can breathe freezing vapor and was used by Ben in Ben 10,000 to freeze down Vilgax. He was first called Absolute Zero by the adult Ben, but was changed by child Ben to its current name. Even then, it just breathes vapor cold enough to just freeze, not of actual absolute zero. It is likely that he won't be used often, since he already has access to Big Chill, who has a freezing powers, in addition to flying and turning intangible.

Appearance
His appearance somewhat resembles a cross of a fish and an iguana. He has the powerful ability to work with cool temperatures, and he can freeze his enemies before they can even lay a hand on him. He seemingly wears white pants and a black open-front shirt with white cuffs. He has three dorsal fins reaching down his back, and gills on the sides of his head. He also has small spikes around his face. Much of Articguana is still not known.

Abilities

 * Creates an icy blast from his mouth capable of freezing objects instantly, as shown when he freezes a large amount of water in only a few seconds.
 * Can live in very cold temperatures.

Weakness
If his breath is used too much, he needs to catch his breath before using it to freeze people again.
