The theme comes from professional wrestler Daniel Bryan, now competing as Bryan Danielson, whose WWE entrance music reworked Richard Wagner's Ride of the Valkyries from the 1870 opera Die Walküre. Renamed Flight of the Valkyries for his entrance, the track became closely linked with Bryan's underdog rise and the Yes Movement in the early 2010s, culminating in his world title win at WrestleMania 30 in 2014. Fans kept sharing the short cue online as a shorthand for heroic entrances, underdog wins and over the top introductions long after the match ended.
