Ultimate Humungousaur

Ultimate Humungousaur is the evolved form of Humungousaur.

Ben as Ultimate Humungousaur
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. His helmet has three silver spikes running down the top, and two downward pointing black horns on the sides. His back armour has long spikes running down each side. His plated chest and torso are dark blue with five spikes on each end. 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.

Albedo as Negative Ultimate Humungousaur
In Alien Force, Negative Ultimate Humungousaur looked exactly like Ben's Ultimate Humungousaur, but he had red eyes and his Ultimatrix symbol was also red.

In Omniverse, Negative Ultimate Humungousaur has greyish-tan skin instead of green and his spikes are yellowish brown instead of silver. His overall appearance is more techno-organic. On his limbs, there are exposed metallic tubes. Some metallic "veins" can also be seen on his skin. The shell on his back is larger and instead has a single row of spikes running down its center instead of two rows on the side. He now has shoulder pads, also with spikes. The spikes on his chest have been replaced with holes. When using the cannons, he now has exposed pale red tissue. There is also a fifth barrel that replaces the black circle at the center. The holes of the barrels are now red. The mace on his tail has stubbier spikes. The spikes on his evolved Ultimatrix symbol are now vein-like and longer. The hourglass symbol is tilted clockwise.

His helmet is silver with three spikes on the top, and two on the bottom and resembles a Styracosaurus more than an Ankylosaurus. The front of his helmet has a dark blue mask, which has a rhino-like horn on top of the nostrils. There are two smaller horns that run down the silver part of his helmet. His ram horns are replaced with tusk-like structures on his mask that point down, while also having a pair of tiny horns above his eye sockets. His eyes are outlined in black and are indented further into his head, being surrounded by pale red skin. His mouth consist of the beak on his mask and a more pronounced lower jaw, with has a large yellow fang on each end and four small skin-colored teeth in between. He also no longer has black lips. There are now three gill-like structures on each side of the silver part of his helmet.

Powers and Abilities
Ultimate Humungousaur is exponentially stronger than full-sized Humungousaur, who himself is strong enough to lift and throw Way Big with ease.

He can make a giant crater in the ground by punching it.

Ultimate Humungousaur has a very durable armor.

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, which deal major damage.

In Omniverse, his hands now spin like real gatling guns when launching the missiles and the color of the bone fragments is now golden.

Ultimate Humungousaur's tail has a mace-like structure which can be used as a flail.

Weaknesses
Ultimate Humungousaur lacks his devolved counterpart's ability to change his size.

His missiles can be absorbed.

Ultimate Humungousaur is also vulnerable to electricity.
