SCP-096

 - The Shy Guy is a Euclid-class SCP from Series I, originally created by the author Dr. Dan in 2012.

The titular subject of SCP-096 (also known by its nickname "The Shy Guy") is a tall, thin, pale humanoid monster that remains docile and passive until someone has seen its face (either in person or indirectly, via photo or video). SCP-096 then becomes enraged and will instinctively hunt down whoever had the misfortune of seeing its face, relentlessly pursuing the target before mauling them to death. 096 is virtually invincible and unstoppable, being capable of easily overcoming all obstacles in its path, along with shrugging off extreme injuries which would kill any normal creature; and it will not rest until after all its targeted victim(s) have been killed, [DATA EXPUNGED], and leaving no traces of their bodies behind.
