Kong roar

Only then did the few human witnesses, too terrified or dumbstruck to flee, grasp the true size and might of the creature who would come to be called King Kong. Powerful beyond description, he stood taller than many trees and was bulkier than any Kong who had ever lived. His roar became so deep and booming that human ears could not endure it; all who heard it fell to their knees, their hands pressed against the sides of their heads.
