Arctiguana

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

Appearance
Articguana's appearance somewhat resembled an iguana. He 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 with white cuffs. He wore the Omnitrix symbol on his left hand.

In Ultimate Alien, the Ultimatrix symbol was on his chest, his eyes were green and his sleeves were fully black.

In Omniverse, Articguana has clothing which covers most of his body. His chest is covered by a white shell. His sleeves are still fully black, and he has four fins instead of three.The fins seem to be more pointed. 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 Omnitrix symbol is on his chest. The spikes on his face are now on his chin. His gills are no longer visible.

11-year-old Articguana in Omniverse has sleeves ending in white when it reaches his hand 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 can create a blast of vapor from his mouth capable of freezing objects instantly. The blast of vapour has a very high range.

He is capable of surviving in freezing temperatures.

Articguana has enhanced strength, durability and agility.

Articguana also has the ability to breathe underwater.

He can climb up walls.

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