"Boss Fight" is a theme composed for Paper Mario: The Origami King. It is a rock track composed on drums and guitar, and plays during the battles against Boss Sumo Bro and Handaconda. The "Thinking" variant of the track removes the main melody, replacing it with a simple backbeat. In the Musée Champignon, "Boss Fight" and its thinking variation are found in the Green Streamer section of the Sound Gallery.

In the Tetris 99 crossover with Paper Mario: The Origami King, "Boss Fight" plays when there are ten or fewer players remaining in a match.
