According to the ultimate forms page the ultimates were put through a tremendous amount of stress or somthing like that that made them so advanced. So ultimate humugousaur would be way better than almost anything in the current ben 10 universe, unless there are many of one thing (example the boids in the episodes final battle part 1 and 2 they all fought ultimate humungousaur as normal humungousaur and ultimate humungousaur just got tired, so just one tyrannopede, or other nemitrix forms and kyber it is extremely unlikely that ultimate humungousaur wouldn't win).
