The clip circulates on soundboards as a standalone reaction line, detached from any longer scene, with the Sentinel name giving it a robotic guard or mutant-hunting machine flavor. Its appeal is how little context it needs: three words instantly frame whoever is on screen as unknown and possibly a threat. Short question clips like this spread easily in gaming, comic and meme edits because they can be reused for entrances, raids, surprise guests and villain reveals without explaining the original reference to the viewer at all.
O tym dźwięku
A 1-second robotic voice clip of a Sentinel asking 'Who are they?', used as a reaction sound for spotting strangers, enemies or unexpected arrivals in edits.
This is a very short voice clip of a Sentinel delivering the line 'Who are they?' in a flat, robotic tone. The delivery is clipped and suspicious, like a guard or machine suddenly noticing intruders it does not recognise. Because the question lands in just over a second, it works as instant punctuation rather than dialogue. Viewers hear it as an alarm being raised, turning an ordinary entrance, reveal or group shot into a moment of tension, curiosity or mock danger before anything else happens in the scene.
