Arctiguana

Articguana is the Omnitrix's DNA sample of a Polar Manzardill from the planet X'Nelli.

Appearance
Articguana's appearance somewhat resembles an iguana.

In Ultimate Alien, Articguana had three dorsal fins reaching down his back and gills on the sides of his head. He also had small spikes around his face. Articguana wore white pants and a black open-front shirt. He wore the Ultimatrix symbol was on his chest.

In Omniverse, Articguana has clothing which covers most of his body. His chest is covered by a white shell. He has four pointed fins instead of three. The clothing goes all the way up to his head and his pants are fully black. The black stripes on his face do not go through his mouth anymore, instead going around his mouth. The spikes on his face are now on his chin. His gills are no longer visible. The Omnitrix symbol is on his chest.

11-year-old Articguana has sleeves with white cuffs and his leg is white and ending in black when it reaches his foot. The Omnitrix symbol is on his left wrist.

Powers and Abilities
Similar to Big Chill, Articguana is capable of firing a long-range freeze ray that isolates targets in ice on contact. The ray can create a icy path that he can skate across in a snowboard-like fashion.

Articguana can survive in any sub-freezing temperatures.

Weaknesses
If Articguana uses his ice breath too much, he'll need to catch up his breath before using it to freeze things again.
