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 has white pants and a black open-front shirt with green cuffs. He has four pointed fins instead of three and the black stripes on his face do not go through his mouth anymore, as they now go around his mouth. The spikes on his face are now on his chin and his gills are no longer visible. The claws on his front feet are pointier and less dexterous, and he now has three claws on each of his back feet. He wears the Omnitrix symbol on his chest.
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.
