True to his word, the Invader King, alongside most of the Invaders, is located deep underground. Reaching there is a large cavern full of organic and fleshy structures. The Invader King itself is situated inside of a cocoon producing new Invaders. With the help of the Rebel Army, the cocoon is destroyed, and the Invader King is presumed dead. That is until it beams its eyes up and starts the fight on its own.
