"I'll Show You" is a collaboration between four TWICE members — Nayeon, Sana, Jihyo, and Chaeyoung — and K/DA, Riot Games' virtual K-pop group built around League of Legends champions. The track also features Bekuh BOOM and Annika Wells, and serves as the closing track on K/DA's debut EP ALL OUT, released November 6, 2020. It marked the first time any TWICE members participated in a K/DA release. Only four of the nine members were involved, as confirmed by Riot Games ahead of release. The song serves as Ahri's character theme within the EP's narrative, and received an official concept video alongside a 1MILLION dance performance video. There is no physical release — this is a digital-only track with no standalone physical edition, making it a streaming/digital-only entry in TWICE's discography. For oncecollector.com purposes, it's worth noting this release has no physical collectibles; it appears here as a discography reference item only.
