One of A Kind

One of A Kind is the 2nd track of Disc 1 of the Bayonetta Original Soundtrack, and the 2nd track of Disc 5 of the Bayonetta 2 Original Soundtrack. It is a recurring theme throughout the Bayonetta series, primarily used for flashback cutscenes and levels that take place during the Witch Hunts.

Bayonetta
One of A Kind is the first theme heard in the original Bayonetta, during the Records of Time narration with Bayonetta and Jeanne fighting angels on the continuingly falling Umbra Clock Tower. It eventually also becomes one of the final themes heard throughout the game, shortly after Bayonetta utters the famous line "We're both one of a kind" to Jeanne while destroying the body of Jubileus. After doing so, the two Umbra Witches assume the original positions and recite the same lines they said at the beginning of the game as they descend towards the Earth.

An 8-bit "retro" version of the track is also heard during Bayonetta's introduction and is a bonus track in the Bayonetta Original Soundtrack, Track 29, Disc 5.

 * Epilogue: Requiem

Bayonetta 2
One of A Kind is replaced as the Records of Time theme in Bayonetta 2 by The Legend of Aesir; however it is later on heard in Chapter XV: Truth when the Umbra Clock Tower crumbles before Rosa and Bayonetta, initiating a sequence similar to that of the opening of the original game.

 * Chapter XV: Truth

Bayonetta: Bloody Fate
One of A Kind makes an appearance in Bayonetta: Bloody Fate most notably as the background fight music during the final showdown between Bayonetta, Jeanne, and Queen Sheba against Balder and Jubileus. A few of the instruments have slightly changed in this version as opposed to the game's version, and the introduction is much cleaner-sounding from the original purposefully scratchy sound in Bayonetta.

Super Smash Bros. for 3DS/Wii U
In the latest installment of the Super Smash Bros. series, One of A Kind appears as a possible background music option for the Umbra Clock Tower stage in the Bayonetta DLC pack, alongside Let's Hit The Climax!, Time For The Climax!, Let's Dance, Boys!, Red & Black, The Legend of Aesir, After Burner (∞ Climax Mix), Friendship, Mysterious Destiny, Tomorrow Is Mine, and Riders of the Light.
