Arctiguana

Articguana is a blue lizard-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 vapour cold enough to just freeze, not of actual absolute zero.

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 semingly 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
His powers are very similar to Big Chill's
 * 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 firing his freezing breath again.

Ultimate Alien
In Ben 10: Ultimate Alien opening, Articguana now has green eyes and the symbol is moved from his wrist to his chest. He no longer has the cuffs of white on his wrists. If he will appear in this series, this will mark Ben's first time to use use Articguana.
