Gabriel is a recurring angelic boss in ULTRAKILL, the fast-paced first-person shooter developed by Hakita and published by New Blood Interactive. He confronts V1, the game's machine protagonist, across the campaign, and his formal, scripture-tinged dialogue has become one of the game's most quoted features among players. Clips of his warnings spread through gameplay videos, TikTok edits and soundboards, where fans reuse them to stage mock confrontations or signal that something dangerous is about to happen. The line endures because it distills Gabriel's role in a few seconds: a proud judge warning an intruder to leave.
