Frostsaurus is the Proto-Ultimatrix's DNA sample of a Polar Manzardill from the planet X'Nelli. Frostsaurus' design was created by Marcus Vms.
Frostsaurus' appearance somewhat resembles a mutated iguana. He has black marks coming from the top of his head down to his mouth, a pocket of ice below his mandible, ice spikes on his back and tail, as well as stubby legs, that can't walk properly, leaving him to pull himself with his arms in order to move. He has three claws on his arms and feet, and the Proto-Ultimatrix symbol is located on his chest. He also has ice teeth.
Powers and Abilities
Frostsaurus 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. 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.
Frostsaurus can use his breath as a means of quickly hovering himself (along with anyone holding on to him) across the ground. Frostsaurus possesses enhanced dexterity, thanks to his three-fingered hands. As such, he can crawl up walls without struggling. Frostsaurus can survive in environments with sub-freezing temperatures and breathe underwater.
If Frostsaurus uses his ice breath too much, he will need to catch his breath before using it again.
Frostsaurus's durability has a clear limit, as he can be knocked out from the impact of landing against a wall.
Due to his body shape, Frostsaurus doens't have enhanced agility like his "normal" counterpart.
