This giant serpent kaiju attacks by inmobilizing his enemies using his body and crushing them with his three jaws. The first jaw looks like a external membrane that catch his enemies and place them on his other two jaws, that are in his mouth.
He never eats his enemies. He spits them with enough power to destroy some buildings.
Niburum only attacks for fun. Though he rarely attacks, is known to be very unpredictable and intelligent. Even if he has to move out of the water, he will find the way to do it properly.
