Naturon's personality changes based on absorption. In his mole form, he appears very dim-witted, irritable, and mainly focused on digging which causes earthquakes. However, after absorbing a person, he becomes very arrogant and bloodthirsty. He is even willing to slaughter presumably hundreds (if not thousands) of innocent people, just for his own pleasure. Upon losing his absorptions and reverting back to his original state, he's very weak, insecure, and cowardly.
