Gilgamesh originates as the legendary king of Uruk in the ancient Epic of Gilgamesh, and modern anime and video games have reimagined him as a supremely powerful and confident ruler. That arrogant persona made his laugh especially memorable, and short clips of it have circulated widely in anime edits, gaming videos and meme soundboards. Creators use it to signal dominance, mockery or a dramatic twist, which keeps it popular long after its original scenes, because the laugh instantly communicates superiority without needing any dialogue or context.
