SCP-049, known as the Plague Doctor, comes from the SCP Foundation, a long-running collaborative horror fiction project where writers document fictional anomalous entities. The character became widely known through SCP – Containment Breach, the 2012 indie survival horror game, where he stalks the player while calmly insisting he is the cure. Short voice clips of the character spread through SCP lore videos and horror edits on YouTube and TikTok, and this line is now used the way fans use other horror game jumpscares from indie horror games.
