Humungousaur (Classic)

Humongousaur is a Vaxasaurian alien from the planet Terradino ('dino' as in dinosaur). Humongousaur is voiced by Dee Bradley Baker

Appearance
Humongousaur is 12 feet tall, and can grow taller and larger at force. His skin is hard, brown and a sort of beige color, and he has a somewhat humanoid body. He carries the symbol of the Omnitrix on his chest(when it's really Ben and not a real species of alien from the planet Terradino). When he grows, his large tail acquires big spikes. He can also evolve into one of the ultimate aliens(Ultimate Humongousaur).

Abilities
He has great strength and a thick layer of skin which provides vast resistance to injury. Humongousaur also has the power to increase his own body size and mass, using dimensional displacement. He can grow up to 60 feet in height(making him Ben's third largest alien right after Way Big 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. Also, on his elbows(and possibly his shins) three plates seperate and grow, giving him a more ferocious look. Recently Humongousaur has proven to be durable enough to survive in space for at least a few minutes.

Trivia

 * As well as being the first alien transformed in Ultimate Alien, he was the first evolved alien seen, although this form was first used by Albedo.
 * He is one of the three aliens to appear in Alien Swarm, the other two are Big Chill and Nanomech. Also, when he appeared, he didn't speak; he only snarled and roared and growled.
 * He can be considered the replacement for Fourarms, due to his big size and tremendous strength. However, it is unknown if he is stronger than Fourarms at normal size, but most certainly is stronger at full size.
 * Humongousaur is the most used alien in Alien Force and also the most used alien in the new series Ultimate Alien.
 * Humongousaur is the first Omnitrix alien used by Albedo, and his Ultimate Form is the last Ultimatrix alien he used.
