Labelled on soundboards as the Nullscape Voidbound guardian beam, this short clip is also shortened by users to Vb guardian, which helps explain why it is easy to find but hard to trace to one exact moment. In practice it circulates as a compact game sound effect for edits, streams and short videos, where a brief beam blast is more useful than a long musical cue. Its short length, clear charge and punchy finish keep it reusable across boss fights, reveals and exaggerated power moments.
