In
My Little Pony Equestria Girls, Applejack first appears delivering fizzy apple cider to
Pinkie Pie, the head of the
Fall Formal planning committee. She tries to dissuade
Twilight Sparkle from running for Princess, telling her that
Sunset Shimmer viciously seeks to humiliate any competition.
It is later revealed that Applejack and the rest of Twilight's new friends had been driven apart by Sunset Shimmer's machinations.
Rainbow Dash had promised to have the school's softball team attend a bake sale that Applejack was running, only for Rainbow to be messaged that the sale had been moved to a different day. Once Twilight convinces Applejack to talk to Rainbow about the misunderstanding, all five friends reconcile and help Twilight get voted for the Princess of the Fall Formal.
When Sunset puts on Twilight's crown and transforms into a "raging she-demon", Applejack briefly channels the element of honesty and gains pony-like attributes.
Applejack reappears in the sequel
Rainbow Rocks and its tie-in animated shorts, where she plays bass in her friends' band, the Rainbooms. She first appears helping her friends make a sign for the
CHS Musical Showcase. At band rehearsal, she helps comfort Sunset Shimmer of all the bad memories of what happened at the Fall Formal. After they perform one song, she wonders why she and her friends gain pony ears and a longer ponytail while they perform even though Princess Twilight took her crown with her when she went back to Equestria.
Throughout the film, Applejack frequently argues with
Rarity about their stage costumes. While trapped under the Battle of the Bands stage, Applejack and her friends reconcile after hearing Sunset Shimmer's speech, and Applejack finally decides to let Rarity use her band outfits for their performances.
Applejack appears briefly at the Sweet Shoppe with her friends, waving to
DJ Pon-3 when she enters.
Applejack appears amongst her friends at the music store and is the one to suggest a musical competition between Rainbow Dash and
Trixie for the expensive guitar.
Applejack once again appears with her friends, as equally frustrated as Rainbow Dash and Rarity with Pinkie Pie's escalating drumming.
Applejack appears in the music room with the other Rainbooms, noting Rarity's lateness is to make a "grand entrance."
Applejack is the lead role in this animated short, wherein her bass is accidentally sold by Granny Smith to pawn shop owners
Flim and Flam. She offers to pay back the two dollars the brothers initially paid for the guitar, but they are skeptical that it even belongs to Applejack. When they go so far as to question Applejack's playing ability, Applejack takes the guitar and plays a skillful bass solo, causing her to transform into her half-pony form. Flim and Flam later have Applejack work off the bass as a costumed mascot in front of their store.
Applejack sings the titular song with her friends and helps set up the auditorium for the Rainbooms' performance, briefly suggesting a rodeo theme.
Applejack sings the song Perfect Day for Fun with her friends and enjoys the Canterlot High School carnival. At one point, she bests Rainbow Dash at a high striker game, only to be bested further by
Spike.
Applejack briefly appears in a flashback putting her hand on Sunset Shimmer's after her defeat.
Applejack performs the song with the Rainbooms and happily interacts with Sunset Shimmer, line dancing with her in one shot.
Applejack appears again in
Friendship Games, competing in the games against
Crystal Prep Academy as part of the Wondercolts team. She participates in the Academic Decathlon, passing the baking contest but failing the spelling bee after misspelling "onomatopoeia".
She is paired up with
Fluttershy during the archery portion of the Tri-Cross Relay. When the human world's
Twilight Sparkle is heckled by her own team for failing to hit a target, Applejack gives her advice that allows her to hit a bull's-eye. This act of honesty causes her to pony-up, but her magic is drained by Twilight's amulet. She later regains her magic to empower Sunset Shimmer and return Twilight to normal after she is transformed into Midnight Sparkle.
In this short, Sunset Shimmer attempts to figure out how magic works in the human world. When she tests it out on Applejack, she ponies-up but was reverted again to normal and somehow, apples fall from the sky, one of which Applejack eats.
Personality:
Applejack is depicted as very reliable, hardworking, and honest. As her friends tend to be quirky, Applejack typically acts as the "straight man" in her circle of friends—much like her Equestrian counterpart tends to be for her friends. She is also considerably strong, able to carry a folding table by herself that normally takes two male athletes to move.
Applejack is also the most level-headed among her friends, able to calmly and logically assess situations that she and the others find themselves in. In Rainbow Rocks, she is the first to question the Rainbooms' ability to "pony up", and in Friendship Games, she is the first one to wonder how Rainbow Dash ponies up without playing her guitar.
Applejack values honesty above all else. She eagerly helps Twilight beat Sunset Shimmer for Fall Formal Princess, and because she places a lot of trust in others, she becomes particularly hurt when that trust is betrayed. It is through Applejack's unyielding honesty that leads her to reaching out to the human Twilight Sparkle in Friendship Games.
