Humungousaur

Humungousaur, or "humongous dinosaur," is a Vaxasaurian from the planet Terradino.

Appearance :
Humungousaur is about 12 feet tall and can grow bigger at will, up to about 60 feet. When he grows, his dinosaur features become more pronounced, growing Stegosaur -like plates on his back, a crest on his forehead and spikes on his tail. Also, on his shoulders three plates separate and grow, giving him a more ferocious look. His skin is hard, brown and a sort of beige color and he has a somewhat humanoid body. When he grows, his tail gains big spikes. Humungousaur wears the Omnitrix / Ultimatrix symbol on his chest.

Appearences :

 * The Elemental Lords
 * Attack of Eunice

Abilities :
He has great strength and a thick layer of skin which provides vast resistance to injury. Humungousaur also has the power to increase his own body size and mass, using dimensional displacement (according to Dwayne McDuffie) growing up to sixty-one feet in height (making him Ben's third largest alien right after Waybig and Ultimate Humongousaur). His strength increases as he grows, and his dinosaur features become more pronounced, growing stegosaur-like plates on his back, a crest from his forehead, and spikes on his tail. Recently Humongousaur has proven to be durable enough to survive in space for at least a few minutes.

Super Form :
Super Humungousaur has metal plates covering his body, and he can create a loud screeching sound from his mouth. He is much larger. His metal scales protect him form weaponry, lasers, and some missiles.
