Humungousaur (Classic)

Humungousaur is the Codon Stream's DNA sample of a Vaxasaurian from the planet Terradino. Ben first transformed into Humungousaur during the episode Ben 10 Returns: Part 2 when fighting Highbreed and chasing DNAlien.

Appearance
Humungousaur is 10 feet tall, and can grow taller at will, up to 60 feet. When he grows his dinosaur features become more pronounced, growing Stegosaur-like plates on his back, a crest from his forehead, and spikes on his tail. Also on his elbows 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 large tail acquires big spikes. The symbol of the Omnitrix/Ultimatrix appears on his chest.

Powers and Abilities
Humungousaur possesses enormous 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. He can grow up to 60 ft (making him Ben's second largest alien after Way Big). His strength increases as he grows, and he can generate his dinosaur features without changing size.

Humungousaur has proven to be durable enough to survive in space for at least a few minutes. A speeding car crashing into him can't hurt him.

Humungousaur also proved that he is very strong by being able to lift a building at full strength and throwing it on Ultimate Aggregor, sending him flying in Map of Infinity.

Humungousaur is also quite agile for his size, as he could somersault onto one of the Forever Knight's battle horses in Eye of the Beholder.
