Arctiguana is the Ultimatrix MK10's DNA sample of a Polar Manzardill from the planet X'Nelli.
Arctiguana has clothing which covers most of his body. His chest is covered by a green shell. He has four pointed fins instead of three. 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 spikes on his face are now on his chin. His gills are no longer visible. The Ultimatrix symbol is on his chest. When 11-year old Ben was in 16-year old Ben's body, his voice was slightly higher.
Similar to Big Chill, Arctiguana is capable of firing a long-range freeze ray that isolates targets in ice on contact, cold enough to freeze molten lava. The ray can create an icy path that he can skate across in a snowboard-like fashion.
Arctiguana can survive in any sub-freezing temperatures.
Arctiguana also has the ability to breath underwater.
Arctiguana can use his breath as a means of quickly hovering himself (along with anyone holding on to him) across the ground.
If Arctiguana uses his ice breath too much, he'll need to catch his breath before using it to freeze things again.
- Articguana was named by 10-year-old Ben Tennyson for Ben 10,000.
