Cassie Cage first appeared as a playable fighter in Mortal Kombat X, released in 2015, as the daughter of series veterans Johnny Cage and Sonya Blade. Her in-game voice lines and combat reactions, including sharp screams when she takes damage, were later clipped and shared on soundboards by players who recognised the sound from matches. Because the clip is short, loud and instantly recognisable to fighting game fans, it has stayed useful for editors who need a quick female scream without recording one themselves, especially for Mortal Kombat edits, reaction content and gaming fails.
