Arctiguana

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

Appearance
Articguana's appearance somewhat resembles a cross of a fish and an iguana. 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. Articguana wears 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 is now on his chest, his eyes are green and his sleeves are fully black.

In Omniverse, 16 year old Articguana's clothing covers more 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 clothing goes all the way up to his head and his pant legs are all black. The black lines on his face do not go through his mouth anymore.

Powers and Abilities
Similar to Big Chill, Articguana can create a blast made of pure ice from his mouth capable of freezing objects instantly. He is capable of surviving in freezing temperatures.

Articguana has enhanced strength, durability and agility.

He can breathe underwater.

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