Eyeless Jack is a prominent figure in the Creepypasta universe, first appearing in a short story posted on the Creepypasta Wiki in 2012. He is depicted as a mysterious entity wearing a blue mask with empty, black sockets that leak a strange liquid, known for surgically removing and eating the kidneys of his victims while they sleep. In internet culture, the character transitioned from a source of genuine horror to a meme favorite, often used in '3 AM' jokes or ironic posts about his specific diet. The image template is frequently used to represent creepy encounters, unexpected guests, or cravings that go a little too far.
