The Chaos Emeralds were introduced in the original Sonic the Hedgehog game released by Sega in 1991 as powerful gems that players collected through special stages. Over the following games and cartoons they became central to the story, linked to transformations like Super Sonic and to villains seeking their power. The short collect chime became familiar through repeated play and later through fan videos, remixes and meme edits online. It remains popular because it instantly signals a rare reward, even for viewers who have never played a Sonic game themselves.
