Shao Kahn is the emperor of Outworld and the final boss of the Mortal Kombat series, appearing in Ultimate Mortal Kombat 3, the expanded arcade update to Mortal Kombat 3 released in 1995. His taunting laugh became one of his signature sounds in the game, heard after victories and during boss encounters. As retro fighting games stayed popular on streams, emulators and soundboards, the clip spread beyond gameplay into edits and memes, where it now signals arrogant victory, mockery and over-the-top villain energy for a new generation of viewers.
