Humungousaur (Classic)

Humungousaur is the Omnitrix's DNA sample of a Vaxasaurian from the planet Terradino.

Ben as Humungousaur
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 arms do something similar. His skin is hard, brown, and a sort of beige color and he has a somewhat humanoid body.. Humungousaur wears the Omnitrix/Ultimatrix symbol on his chest.

In Omniverse, Humungousaur wears black briefs with a white waistband and a green sash across his chest containing the Omnitrix symbol. Humungousaur's fingernails are now grey instead of brown. His chin is also slightly bigger. His nose has shifted to his forehead.

Albedo as Negative Humungousaur
In Omniverse, Negative Humungousaur has a darker skin color and a red sash across his chest in the opposite direction as Ben's Humungousaur.

Powers and Abilities
Humungousaur possesses incredible strength. According to Eugene, Humungousaur is strong enough to lift Way Big. He is able to throw an object to up to a high altitude, even into near-earth orbit.

He possesses a thick, armored hide, which has proven to be durable enough to withstand blaster fire and heavy impacts.



In Vilgax Attacks and Cosmic Destruction, Humungousaur can do a shoulder charge and make shockwaves by slamming the ground.

Humungousaur has the power to increase his own body size and mass. He can grow up to 60 feet. His strength increases as he grows.

Humungousaur can generate his stegosauride features (plates and spikes on spine) without changing size.

In the video game Ben 10: Alien Force, Humungousaur was shown to be immune to freezing.

Humungousaur is durable enough to survive in space for a few minutes.

Humungousaur's tail is powerful enough to knock away Malware's third form easily, as shown in Showdown: Part 2.

Humungousaur is quite agile for his size, as he could somersault onto one of the Forever Knight's battle horses in Eye of the Beholder, perform a slide tackle in Special Delivery and be able to evade while jumping in Showdown: Part 2.

Humungousaur has a powerful roar, which he used to scare away some reporters as seen in Fame.

Weaknesses
Humungousaur's strength is useless against Tyrannopede's sheer weight. He is also very slow and can't fit into small spaces. He is also vulnerable to electricity.
