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


Humungousaur is approximately 12 feet tall. His body is somewhat humanoid and muscular with two arms and two legs. His legs are shorter than his arms. He has elephant-like feet and a lengthly lizard-like tail. His armored hide is light brown, with minor plating on his shoulders, tail, back, arms, and upper legs. He has a beige chest, abs, inner arms, and lower jaw. Dark grey, stone-like spikes, each shaped like the dorsal fin of a shark, run down his spine from the top of his neck to a black mace on the end of his tail. The mace has three spikes shaped like stalagmites, being one large spike on the middle and two smaller spikes on the sides. He has three fingers and a thumb on each hand and three black, elephant-like toes on each foot. His knee caps and finger joints also bulge out.

His square-like head is mostly hunched forward and the beige area of his neck is wrinkled. Both his lower jaw and brows are protruding while his almost human-like nose appears to be squished inward. His lips are black and have wrinkles. His teeth are yellowed and minorly fanged. He also has two green eyes with thick black outlines.

Humungousaur wears the Omnitrix symbol on his chest.

Powers and AbilitiesModifica

Humungousaur possesses incredible strength.

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

Humungousaur's tail is powerful enough to create shockwaves when he slams it against the ground.


Humungousaur's tail can cause unintentional damage if he doesn't watch what it hits. His large size also means he's slow, is an easy target and can't fit in tight spaces.
