DJ Pon-3 (play /ˈdi:dʒeɪ poʊnˈθri:/ DEE-jay pone-THREE) is a female unicorn pony disc jockey who makes several appearances in the series, IDW comics, chapter books, and promotional material. She is called Vinyl Scratch in some merchandise, one of which specifies that as being her real name in-universe with "DJ Pon-3" being a stage name; both names were given by fans.While she has never spoken in the show, she has had several lines in the Friendship is Magic comics and the Enterplay collectible card game.

Design
While DJ Pon-3's coat appears white in Suited For Success due to the lighting of the scene, a layout artist on the show noted that the character model's coat color is actually a very pale yellow, specifically the 24-bit hex triplet #FEFDE7. This is more clearly seen in the episodes A Canterlot Wedding - Part 2 and Magical Mystery Cure. Her coat color in the DJ Pinkie Pie game is the same, while her Playful Ponies toy is white. Her eye color is also shown in the episodes A Canterlot Wedding - Part 2, Testing Testing 1, 2, 3, Slice of Life, and A Hearth's Warming Tail to be moderate cerise, the same as that of Rainbow Dash and many other ponies.

Cutie mark
DJ Pon-3's cutie mark is the mirror image of two bridged eighth notes. It appears as such on the show, on a trading card, and on websites (all showing the left side of her body),[4] but it appears non-mirrored (when showing the right side of her body) on her toy,[5] on the Season 2 poster, and on websites.[6] In the IDW comics' My Little Pony: Friendship is Magic Issue #11 story neigh anything..., Shining Armor's flashback shows her getting her cutie mark watching him, Poindexter, 8-bit and Gaffer perform to get the attention of Princess Cadance.
