Humungousaur

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

Appearance
Humungousaur is twelve feet tall, and can grow taller and larger at will. His skin is hard, brown and white, he has a somewhat humanoid body, and he carries the symbol of the Omnitrix on his chest. When he grows, his large tail acquires big spikes.

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.
