Humungousaur (Earth-68)

This is the version of Humungousaur that appears on Earth-68, the universe owned by Dioga beta. Humungousaur is the Omnitrix's DNA sample of a Vaxasaurian from the planet Terradino. His Ultimate form is Ultimate Humungousaur.

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/Ultimatrixsymbol on his chest.

In John Smith 10, he has his UAF appearance until Omniverse, where he gains his Omniverse appearance.

Weaknesses
