Rengar was released as a playable champion in League of Legends in 2012, designed as a trophy-hunting predator who stalks targets from brush and tall grass. His voice lines were written to emphasize hearing, scent and patience, which is why short commands like listen became memorable among players. Clips of his lines spread through gaming videos, stream soundboards and champion montages, where fans isolated the most threatening phrases for reuse outside matches. The listen line remains popular because it works without gameplay footage, instantly signaling focus and danger.
