Put it near the end of a Viltrumite edit, after a slow build and before the fight resumes. Open with the Dun Dun Dun sting, let this line answer it, then follow with a heavy punch impact as the next clash begins.
About this sound
This short 2.5-second clip is Thragg delivering the line 'Viltrum is not a tomb' in a firm, commanding voice. It feels defiant and tense, like a villain refusing to accept defeat and rallying what remains of his cause. The line comes from Invincible, where Thragg speaks it as a Viltrumite leader determined to preserve his empire.
