== Trivia ==
* The title is a play on the fan titles of battle music from the Mother series, while the latter part of the music references the Touhou series of video games.
* After the beginning, it has the same melody as An Ending, and the later part has the same melody from Don't Give Up, which comes from the Ruins melody.
* The beginning melody is later reused in Power of "NEO" and BIG SHOT from Chapter 2 of Deltarune. The beginning melody sounds similar to Versus, a Homestuck song. The beginning melody also sounds similar to a sped-up version of Doctor from Homestuck.
* Toby Fox, collaborating with ZUN, the creator of Touhou Project, later produced an arrangement piece titled U.N. Owen Was Hero?. It's a mashup of Battle Against a True Hero arranged by ZUN, and U.N. Owen Was Her? arranged by Fox.
