The Devil's Machine is a massive device that appears in EarthBound, and serves to contain Giygas and his tremendous power and stabilize his mind. During the end of the game, Ness and company enter a hole in the Cave of the Past, which leads to a room composed of several pulsing "flesh" tubes; the tubes converge at the end of the "room" where the machine's 'core' (and Giygas) reside. Approaching him causes Ness's face to appear on the machine, and Pokey Minch appears in his spider mech, taunting the party before beginning the final boss battle.
