The Baron of Hell is a large demon enemy from Doom, the first-person shooter released by id Software in 1993. Armed with green fireballs and a powerful melee attack, it became one of the game's most recognisable mid-level threats and later returned in sequels and remakes. Clips of its roar spread through gameplay videos, Doom memes and soundboards, where the short, aggressive sound worked as shorthand for a boss arriving. It remains popular because Doom's retro demon sounds still feel instantly threatening, even in short edits.
