Luigi debuted alongside Mario in Nintendo's Mario Bros. in 1983 and became the taller, more timid younger brother in the Super Mario series. Clips of Luigi calling for Mario come from his voice acting across the games and animated adaptations, where searching for his brother is a recurring plot beat. Short voice lines like this spread on soundboards and in fan edits because they sum up Luigi's character in one call, and creators reuse them for any scene built around looking for a missing friend or teammate.
