Vinyl Scratch

DJ Pon-3, or Vinyl Scratch, is a female unicorn pony disc jockey whose names were given by fans. She makes several appearances in the series, films, animated shorts, IDW comics, and chapter books. She is unnamed in the show and the films, being referred to as simply "DJ" during the reprise of the song This is Our Big Night, but she is named in merchandise, including a trading card which states that "DJ Pon-3 is actually a stage name, and her real name is Vinyl Scratch." She also appears in the "There's a Pony For That" commercial and other promotional material.

The human counterpart of DJ Pon-3 appears in the second film. In one of the scenes, she is seen in the cafeteria listening to music on her headphones during the Dazzlings' song. She can also be seen in five of the eight animated shorts.
In the film, DJ Pon-3 is first seen in the cafeteria. At one point, during the Dazzlings' first song, she is seen bobbing her head to her own music on her headphones. She is then seen at the Sweet Shoppe strutting to her own music in a similar fashion to "Music to My Ears". After the Dazzlings convince Trixie to send the Rainbooms through a trap door on the stage to the area below, Spike arrives with DJ Pon-3 to rescue them. As Spike explains, DJ Pon-3 had been wearing her headphones throughout, making her immune to the Dazzlings' spell. With the Dazzlings on stage, DJ Pon-3 arrives with her car, converting it into a portable DJ station to provide music and speakers for the Rainbooms, allowing them to overpower the Dazzlings and destroy their pendants, rendering them powerless for good. In the credits, DJ Pon-3 has joined the Rainbooms to provide all the hardware and equipment for their performances. She is never referred to by name, nor does she speak in the film.
