Colossus of Akros

Source: Mythic Odysseys of Theros p. 218

An enormous golem of bronze and iron overlooks the path leading to the polis of Akros. Though it is rarely called on to defend the polis, the sight of its towering form is enough to ease the minds of the populace. In truly desperate times, priests of Purphoros work their magic to call the colossus to life, whereupon the earth rumbles as it steps down from its twin plinths to place itself before the threat.
