Spirit Oswald is a fan-made antagonist in Abandoned: Discovery Island.
Spirit Oswald resembles a ghostly version of a normal Oswald suit. Spirit Oswald is completely grey, but with large empty eye sockets with piercing red pupils.
Spirit Oswald is only seen on the Storage Room camera. Spirit Oswald's appearance in this room is rare, but when found, he is seen standing in the middle of the room staring into the camera with his hands to his sides. If the player does not switch to a different camera within 3 seconds, the player will be met with a split-second killscreen that will disable the Storage Room camera for the rest of the night, or until the player dies.
- Spirit Oswald is supposed to represent the soul of the person who was killed inside of the Oswald suit.
- The mechanics are partially based off of Golden Flumpty from One Night at Flumpty's 3.
