Acephalous Prop is a fan-made prop in Abandoned: Discovery Island
Ace's body isn't withered but does have a hole in his chest, with a large spike protruding through him. A smaller spike is attached to the larger one, which holds the head of Acephalous. The head has a glowing orange eye indicating his soul is still trapped inside his suit.
He wants to be free, but his ghost is cursed to loom around the halls of Discovery Island looking for freedom.
