Ultimate Humungousaur is the evolved form of Humungousaur.
Ben as Ultimate Humungousaur
Ultimate Humungousaur is an ankylosaurus-like creature, being about 20 feet tall. Ultimate Humungousaur is green and he has spikes on his head, which are silver.
On the sides of his face, there are black spikes, pointing down. Ultimate Humungousaur possesses a dark blue, spiked shell. His chest and torso is dark blue with spikes on them. Ultimate Humungousaur's tail has a blue mace on the end of it, with silver spikes.
Ultimate Humungousaur's knuckles have barrels on them, which he can transform into four-barreled missile launchers at will.
Albedo as Negative Ultimate Humungousaur
In Omniverse, Negative Ultimate Humungousaur has grey/tan skin instead of green. He has blue shells on his shoulders and his spikes are brown. Also, the spikes on his evolved Ultimatrix symbol are now vein-like and longer, similar veins appear on his arms. His helmet is blue with 3 spikes on the top, and 2 on the bottom and resembles a triceratops more than an ankylosaurus. When using the cannons, he now has red muscles.
Powers and AbilitiesUltimate Humungousaur is exponentially stronger than full-sized Humungousaur and is strong enough to lift and throw Way Big with ease. He has also proven to be strong enough to flatten a Red Robot's head with a few punches.
Ultimate Humungousaur has a very durable shell.
In Cosmic Destruction, Ultimate Humungousaur can do a stronger version of Humungousaur's shoulder charge and punch the ground to create large shockwaves.
As a result of millions of simulated battles over the millennia, Ultimate Humungousaur's genetic evolution allows him to transform his hands into bio-gatling guns that shoot kinetically unstable bone fragments as missiles at opponents which deal major damage. In Omniverse, his hands now spin like real gatling guns when launching the missiles and the colour of the bone fragments is now golden.
Ultimate Humungousaur's tail has a mace-like structure which can be used as a flail, as shown in his fight with Sir George.
Ultimate Humungosaur lacks his devolved counterpart's ability to change his size, due to the Ultimate aliens being combat-based. His missiles can also be absorbed as seen in A Fistful of Brains.
Ultimate Humungousaur is also vulnerable to electricity, as seen in A Fistful of Brains.
