Her name is Katya. She's blonde and a creepypasta fan. She loves to ship everyone. She's talkative and a little obsessive.

• Mask: An egg-shaped, completely blue or dark blue mask with no mouth or nose. In place of eyes, there are two deep, empty sockets.
• Eyes (or rather, the lack thereof): A thick black substance (similar to tar or blood) constantly flows from the mask's empty eye sockets. In some versions, the mask hides the same completely black empty eye sockets, but he still sees everything.
• Clothing: Prefers dark, inconspicuous clothing. His most common attire is a dark blue hoodie and dark jeans.
• Skin: In canon, his skin color was grey.

What does he eat?

Eyeless Jack is a cannibal. His diet is extremely specific:
• Human kidneys: This is his favorite "delicacy" and calling card. In the original story, he sneaks into sleeping people's houses, surgically removes a kidney, and eats it.
• Other internal organs: Sometimes stories mention that he can eat other human organs or meat, but the kidneys always remain a priority. He also loves blood.

Character

Jack's character is shrouded in mystery, as he rarely speaks. His personality can be described as follows:
• Stealthy and quiet: He acts like a ghost or a professional thief, entering homes completely silently without attracting attention.
• Cold and calculating: Jack doesn't commit bloody massacres for fun (like Jeff the Killer, for example). He acts with surgical precision, speed, and focus.
• Loner: He does not seek out communication and keeps aloof from others.
• Animal hunger: In some interpretations, he is driven not by evil intent, but by an irresistible, excruciating hunger that he is forced to constantly satisfy.
• He is often drawn, which irritates him, because of this he comes and runs over the drawing, if he doesn’t like the drawing, he can take the kidney at night, and if he likes it, he will be interested.
•Anatomical and surgical knowledge: He has perfect knowledge of the structure of the human body. He is capable of removing an organ from a sleeping person without the victim even waking up during the process.
