About Champion

"Champion" is a song by American rock band Fall Out Boy, released on June 22, 2017 in the US and on June 23 worldwide through Island Records and DCD2. It was released as the second single from their seventh studio album, Mania. A visualizer was released with the song, and a music video followed on July 28. While Fall Out Boy's previous single, "Young and Menace", was considered to be a major departure from their usual sound, "Champion" brought back some familiar elements from their more recent albums while still experimenting with new ideas. It was co-written with pop singer-songwriter Sia.

The band first performed the song live on Late Night with Seth Meyers on July 26, 2017 to promote the album. A remix of the song featuring South Korean rapper RM was released as a single on December 15, 2017. The song is featured in the soundtrack of WWE 2K19. It was selected by Alexa Bliss to appear in the game's soundtrack.
