Super Smash Bros Ultimate was released for Nintendo Switch in December 2018, directed by Masahiro Sakurai. Its main theme, Lifelight, was composed by Hideki Sakamoto and first heard in trailers before the full vocal version appeared in World of Light. The melody became linked to reveal trailers and the game's huge crossover roster. Fans later reused short excerpts as a hype cue far beyond Smash, placing the rise under entrances, edits and announcements whenever something was meant to feel like a major crossover event.
