Songfacts®:

• Evanescence frontwoman Amy Lee wrote "Fight Like a Girl" for the John Wick spinoff Ballerina after being approached by the John Wick franchise composer Tyler Bates. He asked her to write a song that captures the fire, elegance, and vengeance of a ballerina who also happens to be a deadly assassin.
  
  "It couldn't have come at a more perfect time," Lee said. "I know I'm not the only girl out there ready to dig my heels in and show the world what we're made of."
• Lee was inspired by a pivotal line in the film, "You have to fight like a girl," which helped shape the song's message of strength through subversion.
• Writing from the perspective of a character rather than herself gave Lee a welcome sense of freedom. She wasn't plumbing her own soul this time; she was writing with a mission, within the emotional framework of a woman bent on revenge.
• Evanescence teamed up with K.Flay for the explosive song. Lee personally recruited the alt-rock visionary for the track, hearing her voice in her head as the perfect fit for the bridge.
  
  "I was on tour at the time, and I wrote my verse backstage after a show, when my adrenaline was still super high," said K. Flay. "For me, the film and the song are both about how we channel our pain and how we choose to define ourselves. What separates the hero from the villain?"
• Lee and K.Flay co-wrote "Fight Like a Girl" with producer Dylan Eiland, and with Tyler Bates. Used as the end credit song in Ballerina, it follows "Hand That Feeds," Amy Lee's earlier contribution to the film's soundtrack with Halsey.
• Chad Stahelski, the director of the John Wick films, shot the music video. It marked his debut in music video direction. "We knew we wanted to end the film with a song that personified the tone and energy of John Wick, but with its own identity," he said. "Amy Lee and Evanescence delivered one of the best main-on-end songs ever."
