Ultimate Arctiguana is the Ultimatrix's artificially evolved DNA sample of a Polar Manzardill.


Ultimate Arctiguana has greatly increased in size and his body gained more bulk, and he has what appears to be red armor. He has three growths dangling from his chin, and his teeth are now sticking out of the bottom jaw. He has a "mustache" of sorts, pointing downward and curving inward at the bottom, from either side of his upper lip. He has ice covering sections of his back and shoulders, with large red cannons sticking out. There are also small ice growths on his arms. The black markings on his face have changed, no longer connecting to his eyes and instead move upward between the eyes and end in small hook-like curves facing inwards.

Ultimate Arctiguana wears the Ultimatrix symbol on the ice spikes on his back.

Powers and Abilities

Ultimate Arctiguana is capable of firing a long-range freeze ray that isolates targets in ice on contact.

Ultimate Arctiguana can shoot large columns of ice from his cannons, and propel himself across the ground with their force.
