Dark Horse

"Dark Horse" by Katy Perry is featured on Just Dance 2015 and Just Dance 2015 China.

Dancer
The dance style is a cross between futuristic and Egyptian.

Lead Dancer (P2)
She is supposed to represent Katy as Katy-patra in the official music video for the song. She has blue hair, red shirt and a blue skirt. During the chorus, she is in a golden bodysuit bejeweled with decorations.

Backup Dancers (P1/P3)
The backup dancers begin as the female cat dancers in the music video but with a blue-red scheme. They have red skin.

During the chorus, the cat dancers turn into the male servants (but with blue skin) in the music video and are wearing necklaces and purple shorts and shoes. They do not seem to be wearing tops.

Background
The background seems to have come from the music video. There's a red carpet within a sand fortress and it takes place within a desert. During the chorus, pyramids appear in a dark sky in the background.

Classic
There are 3 Gold Moves in the Classic routine: All: Cross your arms over your chest and then shake your head. The third gold move is the final move for the routine. (Similar to that of Rock n' Roll (Will Take You to the Mountain))

Mashup
There are a total of 3 Gold Moves in the Mashup:

Gold Moves 1 & 2: Bend over and put both your hands behind you while semi-crouching. (Done with She Wolf (Falling to Pieces)) Gold Move 3: Cross your arms over your chest and then shake your head. (Done with Dark Horse [P2])

Mashup
Dark Horse has a Mashup with the theme Mystic Princesses, meaning that it features female dancers with a certain type of special power, or a type of domination. It can be unlocked for 20 Mojocoins.

Trivia

 * The song was accidentally leaked on UbiBlog and Uplay.
 * It was taken off of both pages immediately.
 * This song was one of the five leaked songs to be on Just Dance 2015, along with Summer, Happy, Burn, Built For This and Dancing Queen, although Dancing Queen didn't appear in the final game.
 * This is the eleventh song by Katy Perry in the Just Dance series. It was preceded by Hot n Cold as the first in Just Dance, Firework' as the second in Just Dance 2 (as a DLC), California Gurls', E.T. and Teenage Dream as the third, fourth and fifth in Just Dance 3, Part of Me as the sixth in Just Dance 4 as a DLC, I Kissed a Girl', Roar' Waking Up in Vegas as the seventh, eighth and ninth in Just Dance 2014, and Birthday, which is also in Just Dance 2015, as the tenth.
 * This is the fourth Egyptian-themed routine in the series after Walk Like an Egyptian, Night Boat To Cairo and Rich Girl.
 * With the exception of the I Kissed a Girl 's On-Stage routine, this is the first Katy Perry song to not be a solo dancer,
 * This is also the only song by Katy Perry with male dancers in the Classic mode.
 * Juicy J's part was taken out.
 * In the picture of the full song list Dark Horse was not listed.
 * This was likely to surprise the fans that Dark Horse, not included in the game, was added.
 * The routine takes many elements from the music video.
 * The background resembles the one in the music video a lot.
 * The dancer is wearing an outfit similar to Katy Perry's in the music video.
 * The beginning is just like the second verse of the music video.
 * In the chorus, the dancers do the official choreography from the music video.
 * The painting on the beginning and the end is inspired on the one from the teaser of official music video.
 * The song's dancer card avatar is one of the few to have eyebrows.
 * There are a total of 11 dancers in the classic mode. However, only three are playable.
 * In the song selection menu, four backup dancers can be seen instead of the two playable ones. This is the first time non-playable clone backups are seen in the background of the song selection menu for a song with backups.
 * In the gameplay, the line "We're down to earth" is incorrectly written as "But down to earth".
 * This routine reuses a move from Call Me Maybe and The Way.
 * This is one of three times All I Want for Christmas Is You makes an appearance, with the others being Holding Out for a Hero's and Summer 's party master modes.
 * The lead dancer's choreography is performed by Juliana Casas Herrera.
 * On the World Dance Floor, whenever this song is chosen for play without voting, the backup dancers are not selectable. Instead, the player will choose between two topics (like solo routines that were chosen without voting or VIP), and the player will be advised to follow the lead dancer.
 * In the Mashup, the dancers seem to have been enlarged.
