Orochi Iori is the possessed form of Iori Yagami, the rival of Kyo Kusanagi in SNK's The King of Fighters fighting game series, which began in the mid-1990s. When the Orochi blood within Iori awakens, he becomes faster, wilder and far more violent, and his screams mark that transformation in battle. Clips of the form spread through fighting game communities, gameplay videos and fan edits, where the scream became shorthand for losing control or unleashing hidden power, and it remains popular for dramatic, high-energy edits.
