SCP-173 is the original entry of the SCP Foundation, a collaborative horror-fiction project that began on 4chan's /x/ board in 2007: a concrete statue that moves only when unobserved and kills anything it reaches. The concept exploded through the indie game SCP – Containment Breach in 2012 and years of YouTube narrations, becoming the mascot of internet horror. Short ominous drones like this one now circulate as meme audio, dropped into edits to signal that something awful is about to happen, often right before a scream meme payoff.
