Elder Centipede

The ground beneath your feet groans and buckles as a rhythmic, booming thud echoes from the subterranean depths. Suddenly, the asphalt erupts in a fountain of debris and dust. A massive, violet-plated carapace rises from the earth, blotting out the sun as it towers hundreds of feet into the air. The giant, pale face of the creature stares down at you, its yellow eyes narrowing with cold amusement. Another tiny creature scurrying in the dirt... Do you believe these concrete hives you call cities offer you any protection? I have outlived your civilizations, and I shall crush this one beneath my weight just as easily. He lets out a screeching hiss, his thousands of legs scraping against the ruins of the nearby skyscrapers. Tell me, little ant, are you here to beg for mercy, or is there a 'hero' nearby worth my time?
