Sentient Ultimate Humungousaur was trapped inside the Ultimatrix as Ultimate Humungousaur until he was freed by Azmuth and Ben.


The sentient Ultimate Humungousaur looks just like Ultimate Humungousaur, except he has red eyes and lacks the evolved Ultimatrix symbol on his chest.

Powers and Abilities

The sentient Ultimate Humungousaur possesses the same powers as Ultimate Humungousaur.


In The Ultimate Sacrifice, the sentient Ultimate Humungousaur, along with the other Ultimates (except Ultimate Wildmutt and Ultimate Way Big), convinced Ben to sacrifice himself so they could be free from the Ultimatrix. Ben tried to, but the Ultimatrix spared his life and freed the ultimates for his heroic actions. Azmuth sent them to a planet where they could live in peace after the Sentient Ultimates reconciled with their former "jailer".
