On May 16, 2013, Meghan McCarthy wrote on Twitter, "So funny people are calling blue haired guy in #EquestriaGirls 'Brad.' His name is obviously 'Dreamy Cutebottom' #notreally."

My Little Pony Equestria Girls
In My Little Pony Equestria Girls, Flash Sentry appears as a student of Canterlot High School. When Twilight Sparkle runs into him in the school hallway, he helps her up and asks, "Whoa. You okay?" Later, Twilight accidentally spills a beverage on him at the Sweet Shoppe, and he jokes they need to stop bumping into each other. Rarity reveals to Twilight that he is Sunset Shimmer's ex-boyfriend.

When Sunset Shimmer frames Twilight for ruining the Fall Formal decorations using photographic proof, Flash Sentry proves that the photos are fake and Vice Principal Luna allows Twilight Sparkle to continue running for Fall Formal princess. Twilight is so thrilled that she hugs Flash Sentry. He asks Twilight out to the Formal, but he mistakes her panicked "no's" as her response.

When the Formal goes on as originally scheduled, Twilight clears up the misunderstanding with Flash Sentry and agrees to have one dance with him. The Formal is disrupted when Sunset Shimmer rises to power and hypnotizes the students, including Flash Sentry. Twilight and her friends defeat Sunset Shimmer, turning everyone back to normal. Flash Sentry finally asks Twilight for their dance, and he imitates her odd dancing style on the dance floor, previously seen in Sweet and Elite.

Equestria Girls: Rainbow Rocks
In the second film, Flash Sentry compliments the Rainbooms on their playing and asks them if Twilight will return for the school's musical showcase. He is later seen in the cafeteria during the Dazzlings' song. At one point, Sonata Dusk strums the strings of his guitar.

Like most of the Canterlot High School student body, Flash and his band fall victim to the Dazzlings' spell and becomes overly competitive. During the Battle of the Bands, he and his band, which is specified in the first film's screenplay novelization Equestria Girls: Through the Mirror to be named "Flash Drive", faces off with the eco-kids. He also shows hostility toward Twilight, causing her to cry.

When the Dazzlings' spell is broken, Flash congratulates Twilight and hugs her, but Trixie interrupts their affectionate moment.

Perfect Day for Fun
In the My Little Pony Equestria Girls: Rainbow Rocks animated short Perfect Day for Fun, Flash Sentry appears at the Canterlot High carnival and watches the Rainbooms' concert.

Friendship Through the Ages
In the musical short Friendship Through the Ages, Flash partially appears during Rainbow Dash's verse.

Life is a Runway
In the musical short Life is a Runway, Flash appears as a silhouette during the fashion runway sequence.

Equestria Girls: Friendship Games
Flash Sentry appears again in the third film as one of twelve students selected to represent Canterlot High School in the Friendship Games. He is shown to be bitter towards their losing streak against Crystal Prep Academy when he heckles Principal Celestia's pep rally about it.

Flash Sentry encounters human Twilight Sparkle twice in the movie. When she first arrives at CHS, she drops her glasses after bumping into him and he returns them, mistaking her for the Twilight he knows. He later congratulates her after she wins the Academic Decathlon for Crystal Prep. Both times, she blows him off to study her magical readings, much to his disappointment and confusion.

Flash is partnered with Sweetie Drops for a baking competition during the games' academic decathlon, but they are eliminated when they mistakenly bake a loaf of bread instead of a cake.

Flash is later seen witnessing Twilight and Sunset's magic duel. He also appears in several photographs during the film's ending credits.

A Banner Day
Flash and his friends Micro Chips and Sandalwood are tasked with making a banner to welcome Crystal Prep Academy to the Friendship Games. Flash's ideas for the banner conflict with those of his friends, but the final product is met with approval from Vice Principal Luna.

Chapter books
Flash Sentry appears in the screenplay novelization of the first and second films, and he is mentioned in the narration of chapter 1 of the My Little Pony: Equestria Girls: Rainbow Rocks screenplay novelization of the first eight animated shorts, "The Ponies in the Band!"

Flash also appears in My Little Pony: Equestria Girls: Sunset Shimmer's Time to Shine. In chapter 2, "Storm on the Horizon," he overhears Sunset Shimmer and her friends talking about Twilight Sparkle, and in chapter 14, "With Flying Colors," Sunset helps him with a math problem.

Flash Sentry is featured in Hasbro's Equestria Girls online games V.I.F., Dash for the Crown, and Battle of the Bands, and in the Equestria Girls app.

Merchandise
Two Equestria Girls dolls of Flash Sentry were released for My Little Pony Equestria Girls: Friendship Games. One was shown at the 2015 New York Toy Fair and released in a two-pack doll set with human Twilight Sparkle. The other, a Kmart-exclusive, was released in a singles pack.

Personality
Flash Sentry is portrayed as kind and gentlemanly, as evidenced by his helping Twilight when she falls over. He returns Twilight's feelings of affection towards him. In the first two films, he also shows signs of social awkwardness and clumsiness, such as walking into a door while escorting Twilight to the Fall Formal dance and backing into a wall while exiting the band room.

While under the effect of the Dazzlings' magic, Flash becomes arrogant, cold, and spiteful. He lashes out at Twilight when she takes part in the Battle of the Bands, believing that she is trying to take victory away from him and he publicly ridicules Sunset Shimmer, calling her "the bad girl we love to hate."
