DJ Pon-3

DJ Pon-3, or Vinyl Scratch, is a unicorn pony disc jockey whose names were given by fans. She appears in Suited For Success, A Canterlot Wedding - Part 2, Magical Mystery Cure, the film My Little Pony Equestria Girls, Simple Ways, My Little Pony Equestria Girls: Rainbow Rocks/Animated shorts including Music to My Ears and Guitar Centered, Testing, Testing, 1, 2, 3, and books including IDW comics and chapter books. She is unnamed in the show and the film, being referred to as simply "DJ" in the film's reprise of its 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." Similarly to Princess Cadance/Princess Mi Amore Cadenza, DJ Pon-3's in-universe real name Vinyl Scratch isn't her primary name. She also appears in the "There's a Pony For That" commercial and other promotional material.

Color
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 and Testing, Testing, 1, 2, 3 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), but appears non-mirrored (when showing the right side of her body) on her toy, on the Season 2 poster, and on websites. In the IDW comics' 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.

Depiction in the series
During the opening of Rarity's first fashion show in Suited For Success, DJ Pon-3 appears for a brief three-second moment, operating a turntable with her unicorn magic. During the post-wedding party in A Canterlot Wedding - Part 2, Pinkie Pie pulls her up from under the turntable and they spin the records. She briefly lifts her glasses, revealing her magenta-colored eyes before closing them and nodding to the beat. During What My Cutie Mark Is Telling Me in Magical Mystery Cure, she appears at Sugarcube Corner as one of the ponies Fluttershy fails to make laugh. She makes a cameo appearance in a crowd shot in Simple Ways. In Testing, Testing, 1, 2, 3, she is shown providing music during Pinkie Pie's song The rappin' Hist'ry of the Wonderbolts, and reveals her magenta-colored eyes again.

My Little Pony Equestria Girls
The human version of DJ Pon-3 makes several appearances in My Little Pony Equestria Girls, including hallway cameo appearances, in the cafeteria and at the Cakes' café. In the cafeteria, Applejack removes her glasses during the song Equestria Girls. She later serves as a disc jockey at the Fall Formal.

My Little Pony Equestria Girls: Rainbow Rocks
The human version of DJ Pon-3 appears in animated short clips in the trailer for the sequel, My Little Pony Equestria Girls: Rainbow Rocks. In one of these clips, she spins while wearing the Canterlot Wondercolts ears and tail. She also appears on the cover of the novelization of the shorts. In the novel prequel to the film, she does not speak. Instead, she chooses to communicate through text messages.

Music to My Ears
In the mostly wordless short Music to My Ears, DJ Pon-3 crosses the street listening to dubstep on her headphones. She is seen busting a move on a city sidewalk, while a policeman imitates the same move. She stops by Sugarcube Corner to get something to eat. She then goes into the Canterlot High hallway only to be stopped by Principal Celestia, who takes her headphones away from her. When Celestia disappears, DJ Pon-3 resumes her music on her earbuds.

Guitar Centered
In the animated short Guitar Centered, DJ Pon-3 is shown working at a music store and greeting the main cast's human counterparts as they enter. After Rainbow Dash wins over Trixie in their shred-off, she presents Rainbow Dash with her prize: the double-necked guitar that she and Trixie were fighting over.

Depiction in promotional material
DJ Pon-3's name is mentioned 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 as "DJ Pon3" in the "There's a Pony For That" commercial.

DJ Pon-3's brief appearance at a turntable in A Canterlot Wedding - Part 2 was featured in several advertisements and other promotional material, such as a computer wallpaper. One of the Flash assets on The Hub's website depicts her, when the Flash file is decompiled and its assets are rearranged, with magenta irises underneath her purple-pink glasses, prior to their appearance in the show. One of the backgrounds on Hasbro's Pony Wedding site depicts her with the same eye color.

When a party needs the hottest music in Equestria, there's only one pony to call: DJ PON-3!

First party
On 11 February 2012, Hasbro's My Little Pony Facebook page announced that a DJ Pon-3 toy would come out in Fall 2012, as part of a Toys 'R' Us exclusive pack, later revealed to be part of the Toys 'R' Us exclusive Collector Series and to be named the Friendship Is Magic Favorite Collection Featuring Nightmare Moon. In the initial announcement, DJ Pon-3 was called a "fan favorite."

A mini-figure toy of her was leaked in mid-August 2013.

DJ Pon-3, along with a host of characters from the show, appears on the Comic Con 2011 promotional poster.

She also appears as a 2013 Comic-Con Exclusive donning Swarovski crystals on her horn and sunglasses.

Second party
Series 1 of Enterplay's trading cards includes a DJ Pon-3 & Octavia base collectable card, #27 of 84, with the description "DJ Pon-3 and Octavia may both be at the top of their musical games, but their careers are very, very different! You can find Octavia at garden parties and galas performing prim and proper classical music on her cello. On the other hoof, DJ Pon-3 feels at home behind her turntable, laying down sick beats and wearing her trademark sunglasses. Are these two bitter rivals, or are they long time friends? Will they ever perform a duet? Only time will tell!"

Series 2 of Enterplay's trading cards includes a DJ Pon-3 special card, #F41, with the description "No ultimate pony party is complete without the wicked beats of DJ Pon-3! This musical pony is rarely seen away from a turntable, and never without her infamous shades. Whether she’s spinning for a fashion show or the wedding of the century, DJ Pon-3’s got what it takes. Not many ponies know that DJ Pon-3 is actually a stage name, and her real name is Vinyl Scratch. No matter what name you know her by, if your bass needs dropping, this is the pony for the job!"

WeLoveFine sells several fan-designed T-shirts and other merchandise featuring DJ Pon-3. One bears the name "Vinyl Scratch", and the titles of some others refer to her by that name.
