DJ Pon-3

DJ Pon3 is the fan-given name of a unicorn pony who performs as a disc jockey in Suited For Success. The name "DJ Pon3" was later used in two promotional videos for the show on The Hub.

In the series
When Rarity holds a fashion show for the Grand Galloping Gala dresses that she made for her friends, a unicorn pony wearing purple tinted sunglasses is seen for a brief moment using her unicorn magic to operate a turntable, around the 13:37 mark. Her cutie mark is the mirror image of two bridged quavers. While her coat appears white in the scene, a layout artist on the show noted that the character model's coat color is actually a very pale yellow.

In commercials
Her name is first mentioned in official material in the Equestria Girls commercial where it is pronounced "dee jay pon-three". The video also references bronies and other online Friendship is Magic phenomena. Her name was later spelled in the "There's a Pony For That" commercial.
