Pacific Rim is a 2013 science fiction film directed by Guillermo del Toro, about human pilots controlling giant mechs called Jaegers to fight Kaiju monsters emerging from the Pacific Ocean. Its score by Ramin Djawadi became known for heavy guitar, brass and percussion that match the film's enormous scale. Short epic excerpts like this one spread online as trailer style music for edits and memes, where the Pacific Rim name signals a heroic last stand against an overwhelming enemy and a battle too big for normal stakes.
