Vinyl Scratch

DJ Pon3, also "DJ P0N-3" and "Vinyl Scratch", is a fan-named background pony whose first and so far only appearance in was in the episode. In fan labor, she is commonly depicted with red eyes and sometimes as blind.

Name
The pony's name originated on /co/, where she was dubbed "Vinyl Scratch" and "DJ PON-3". A poll on Equestria Daily cemented her name as DJ PON-3. Hasbro later used a variation of the name, DJ Pon3, on their commercial, and yet another one, DJ Pon-3, in a February 2012 announcement that a toy version of the character would be released as a Toys'R'Us exclusive in the autumn of 2012.

To reconcile both names, many fans assume DJ Pon3 to be her stage name, with Vinyl Scratch being her real name. The stage name itself is a possible reference to DeadMau5, since both utilize a number in place of a letter at the end.

Personality
Vinyl is a hip-hop DJ to the core and is the go-to mare if you want to take part in Ponyville or Canterlot's night scene. She's known to be wild, unpredictable, and sometimes borderline insane, not giving a hoot what anypony else thinks of her words and actions. She's often paired, whether romantically or simply as a Odd Couple friendship, with the more cultured and sensible Octavia. While Vinyl generally finds Octavia's choice of music boring and can be a horrible tease, she does respect the earth pony and is usually the one to initiate the friendship/relationship if the two don't know each other from the get-go of a fic or comic.
