What was K/DA's debut single at the 2018 Worlds opening ceremony?

K/DA’s debut single at the 2018 Worlds opening ceremony was “Pop/Stars.”

Riot Games unveiled K/DA during the League of Legends World Championship finals in Incheon, South Korea, on November 3, 2018. The performance combined live singers with augmented-reality versions of four League champions: Ahri, Akali, Evelynn, and Kai’Sa.

The recording featured Madison Beer, Jaira Burns, and (G)I-DLE members Soyeon and Miyeon. The song blended English and Korean vocals with K-pop, pop, and trap influences, helping K/DA function as both a fictional game-world group and a real-world music project.

A common mix-up is confusing “Pop/Stars” with later K/DA releases. “The Baddest” arrived in 2020, while “More” was released later that year as part of the group’s All Out era. “Villain” is another K/DA song, but not the debut single.
