The Shy Guy is a humanoid organism that is unique due to its attributes. It is an extremely timid creature that dislikes others seeing its face. Whenever another being sees its face through direct or indirect means, it tracks the person to its location, and then eats them alive. Studies of the creature suggest that it possesses omniscience that stems from a form of global level telepathy.
Because of its omniscience, the Shy Guy is able to detect whenever somebody sees its face. This is regardless of the medium, it could be through a camera or even pixels on a photo. This person could be anywhere on the planet, including underwater, on a plane, or in a secluded mountain range.
What is strange is that, while this telepathy is world wide and powerful enough to reach all corners of the planet, it isn't able to detect anything other than when someone is looking at its picture. Its omniscience is unlimited in range, but limited in its abilities. This is counter to Cerebro, a machine that is able to detect where mutants are and what they are doing, as well as look into their minds.
How can this be the case?
