Ultimate Humungousaur is the Ultimatrix's evolved form of Humungousaur. He is an evolved Vaxasaurian from the planet Terradino in Earth-1010.


Ultimate Humungousaur is a massive bipedal Ankylosaurus-like creature. He is considerably larger than his unevolved counterpart. He has a dark black shell over his back lined with grey spikes. His chest and stomach is also covered in black plates. His head is armoured with plates, similar in shape to a helmet. His skin is now a deep mucky green. His knuckles have silver barrels on them, and his tail has a mace-like weapon on the end.

Powers and Abilities

Ultimate Humungousaur is stronger than even full-grown unevolved Humungousaur.

His shell is incredibly durable, able to shake off explosions with ease.

His hands can morph into biological gatling guns, dispensing explosive bone fragments with a high rate of fire.

His tail packs one hell of a punch when used as a flail.


He lacks his unevolved form's ability to change size.

The shell on his back is inflexible, making it difficult for Ultimate Humungousaur to manoeuvre, particularly through smaller spaces.


Death of Ben 10

Ultimate Ben 10

Ultimate Ben 10 used Ultimate Humungousaur in Chapter 11 to battle Apollo, but ended up destroying the control console for the warship sending it on a collision course with the Earth before it was stopped. This scene was shown again in Chapter 13 in the form of one of Ultimate Clockwork's Holograms.

Ultimate Ben 10'000

Ultimate Ben 10'000 used Ultimate Humungousaur as an Aspect Transformation of Ultimate Ben to battle and defeat some of Apollo's workers in San Diego Ironworks.
