Thragg is the leader of the Viltrumites in Invincible, the superhero story that began as a comic and became a popular animated series. His introduction is memorable because he does not need to raise his voice to sound like a threat, and that contrast has made the short line a favourite for fan edits and power-scaling videos. As clips of the series spread across social platforms, creators began using the name drop as shorthand for an unstoppable villain arriving, and it remains useful because it is instantly recognisable to fans without needing extra context.
