Susie is a central character in Toby Fox's Deltarune, a role-playing game that began with its first chapter in 2018. As the party's tough, impulsive fighter, she became a fan favourite, and music tied to her confrontations is widely shared in gameplay clips, edits and memes. The track is often used online to signal a showdown, a bold entrance or a moment when a character refuses to back down, which is why it keeps appearing in versus videos and gaming compilations long after players first met her.
