“ Do you wanna see my head come off? ”
Photo-Negative Mickey is the main antagonist in the main story of Treasure Island.

Appearance
Gen 1
In his Gen 1 design, Photo-Negative Mickey, as his name suggests, is a photo-negative Mickey Mouse toon with most features of his Disney counterpart. However, he has some substantial changes. He is considerably melted and distorted, and has missing eyes. He has a white body and nose with a dark blue face, and wears cyan shorts with black buttons, black gloves, and blue shoes. He also is missing his tail. When Photo-Negative Mickey is seen in one of his rare screens of himself taking his head off, both the body and head are a separate part as such, taking his head off will cause his body to bleed thick black ink.

Gen 2
In his Gen 2 design, he retains his photo-negative aspect with a complete overhaul into his appearance. While not as melted and distorted aside to his ears, he does have visible dents in his body with a more lighter tone of white and blues, though slightly covered with yellow stains from aging. This version of his design also retains his tail for the first time.

Behavior
Photo-Negative Mickey becomes active on Night 1. He starts in the Mascot Prep and will walk around the building towards the player, taking a path through the Freezer or the Lounge, appearing at both left and right sides of the Office depending on the path he takes. When he appears in the Office, the player must shut off a camera. Turning off the lights also has a 50/50 chance to deter him. If the player takes too long, then Photo-Negative Mickey will kill the player.
