'One Way Ticket' is a track from Alan Silvestri's score for Avengers: Infinity War, the 2018 Marvel Studios film, and it underscores the moment Thor, Rocket and Groot arrive in Wakanda to turn the battle. The upload's Spanish title means 'You are an Avenger', a nod to the scene's hero-welcome energy. The cue spread online as edit audio on TikTok and YouTube, where creators use its swelling fanfare to soundtrack heroic entrances and victories, alongside other hero themes like Spider-Man 2099 or the Prowler score.
