Ultimate Humungousaur

Ultimate Humungousaur is the evolved form of Humungousaur. He first appears in Ben 10 Alien Force in The Final Battle: Part 1 where it is first used by Albedo to fight Ben. Ben first used him in the Ben 10: Ultimate Alien episode, Too Hot To Handle.

Abilities
Like Humungousaur, Ultimate Humungousaur is an enormous ankylosaurus-like creature. But Ultimate Humungousaur has much tougher, green skin and nearly impenetrable armor plating similar to an exoskeleton, and is 12 feet tall. His muscle fiber has increased greatly, making him exponentially stronger than before. He is strong enough to easily overpower the normal Humongousaur. As a result of millions of simulated battles over millennia, his genetic make-up now allows him to form his hands into bio-gatling guns that shoot kinetically unstable bone fragments as missiles.

Ultimate Alien
He first apears in Too Hot To Handle, while fighting P'andor and his helpers. He later apeared in Hero Time Whee he was furious at Overlord for taking Julie. Overlord was no match for him but he has to change into goop to save julie.
