Another reasons:

1. They said in the wiki that Palorfang overpowered Humungousaur and Kevin which means that he is stronger that Four Arms and Humungousaur and others. Also he is bigger than Humungousaur and he is nealry as big as Gravattack and Tiny's species(mature). And I think Gravattack, Palorfang and Tiny's species(mature) are as strong as each other.
