Arctiguana is the Omnitrix's DNA sample of a Polar Manzardill from the planet X'Nelli.
As his name suggests, Arctiguana's appearance somewhat resembles an iguana. He resembles his Omniverse design, but with broader fins, and his eyes are again connected from the top of his head to the bottom of his mouth. His suit is green on the back and black on the belly, where icy fissures can be found. The Omnitrix is in the dorso of his left hand.
Powers and Abilities
Arctiguana is capable of breathing ice and firing a long-range freeze ray that isolates targets in ice. This ice breath is cold enough to freeze large bodies of water and molten lava. Arctiguana possesses enhanced agility, as seen when skating across an icy path in a snowboard-like fashion. In the same scenario, he can use his ice breath to create constructs made of ice. He also possesses enhanced strength and durability, and can make an Arachnichimp's webbing brittle enough for him to break free of.
Arctiguana can use his breath as a means of quickly hovering himself (along with anyone holding on to him) across the ground. Arctiguana possesses enhanced dexterity, thanks to his three-fingered hands. As such, he can crawl up walls without struggling. Although he has never trained himself to do so, Arctiguana can survive in environments with sub-freezing temperatures and breathe underwater.
If Arctiguana uses his ice breath too much, he will need to catch his breath before using it again.
Arctiguana's durability has a clear limit, as he was harmed to the point of uncontrollably flying across an open area when being stabbed by Unitaur's horn and was knocked out from the impact of landing against a wall.
