Bad Arctiguana is the Omnitrix's DNA sample of a Polar Manzardill from the planet X'Nelli.
As his name suggests, Bad Arctiguana's appearance somewhat resembles an iguana. He has mint pants and a black open-front shirt with mint cuffs. He has four pointed fins instead of three and the black stripes on his face go around his mouth. The spikes on his face are on his chin and his gills aren't visible. The claws on his front feet are pointy and not very dexterous, and he has three claws on each of his back feet. He wears the Omnitrix symbol on his chest.
Powers and Abilities
Bad 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. Bad 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.
Bad Arctiguana can use his breath as a means of quickly hovering himself (along with anyone holding on to him) across the ground. Bad 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, Bad Arctiguana can survive in environments with sub-freezing temperatures and breathe underwater.
If Bad Arctiguana uses his ice breath too much, he will need to catch his breath before using it again.
Bad 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.
