The Green Hill Zone Boss is an object in Sonic the Hedgehog, serving as one of 6 boss fight objects in the game. This object is the ship, with the face, the exhaust flame, and the swinging ball being their own objects. Like all other bosses, this object is programmed to take 8 hits from Sonic before entering an exploding routine. The level ends as the boss flees, unlocking the screen and clearing the way for the Prison Capsule.
