Ultimate Humungousaur is the Ultimatrix's artificially evolved DNA sample of a Vaxasaurian.


Albedo as Negative Ultimate Humungousaur[]

Negative Ultimate Humungousaur is a humanoid dinosaur-like creature, with dark blue armor similar to that of an Ankylosaurus. He is more burly and muscular than his pre-evolved form.

He has camo green skin and his helmet[DJW 1] has three silver spikes running down the top, and two downward pointing black horns on the sides. His back armor has long spikes running down each side, his plated chest and torso are dark blue with five spikes on each end and his tail has a blue mace on the end of it, with silver spikes.

Ultimate Humungousaur's knuckles have silver barrels on them, which he can transform into four-barreled missile launchers. He has black claws.

Ultimate Humungousaur wears the evolved Ultimatrix symbol on his chest.

In Omniverse, Negative Ultimate Humungousaur has greyish-tan skin, his spikes are yellowish-brown, and his shoulders sport armor plating. His overall appearance is more techno-organic, almost like a cyborg. He has exposed metallic tubes on his skin and black "veins" on his skin. He wears the Ultimatrix symbol on his chest.

Ben as Ultimate Humungousaur[]

In Ultimate Alien, Ben's Ultimate Humungousaur looks exactly like Negative Ultimate Humungousaur in Alien Force, except his eyes and Ultimatrix symbol are green.

Powers and Abilities[]

Ultimate Humungousaur can transform his hands into bio-gatling guns that shoot missiles[note 1] which deal major damage, and can even damage and knock out a Petrosapien.[1] Ultimate Humungousaur can also shoot out bullets.[2]

Ultimate Humungousaur is exponentially stronger than Humungousaur, even being able to fight off Vilgax's army of Bioids transformed as Humungousaur.[3] He is also strong enough to lift and throw a To'kustar,[4] and rupture the ground by just punching it.[3]

Ultimate Humungousaur has impeccable durability, thanks to his hard-armored body and muscular bulk. This is best seen in his fight against Atomix, where he was able to withstand his Nuclear Punch and an atomic blast.[5]

Ultimate Humungousaur has both great agility and great reflexes, as he was able to easily dodge attacks from Antonio.[6]

Ultimate Humungousaur's tail is powerful enough to knock away his opponents, such as Carl Nesmith, with ease.[7] He also has a mace on his tail for some extra damage.


Ultimate Humungousaur lacks his devolved counterpart's ability to change his size.[DM 2][DM 3][DM 4]

Ultimate Humungousaur's size can make moving through areas designed for smaller species difficult.[8]

Like Humungousaur, Ultimate Humungousaur is vulnerable to electricity, such as that generated by a Conductoid.[1]
