Depiction in the series
Vapor Trail appears in the season six episode Top Bolt as an applicant to the Wonderbolt Academy. She is introduced as Sky Stinger's timid and soft-spoken best friend and wingpony. During the classroom portion of applicant testing, Vapor praises Sky Stinger's flying skills to instructor Rainbow Dash. However, it is revealed during freestyle training that Vapor Trail supports Sky when he flies by blowing wind under his wings. As a result, she pays no attention to improving her own flying.
In the cadet locker rooms, Vapor Trail explains to Twilight Sparkle and Rainbow Dash that Sky Stinger grew up with a lot of siblings and often competed with them for their parents' attention while she grew up as an only child with parents who smothered her with affection. When Sky struggled to impress his parents with his flying, Vapor gave him a wind boost and congratulated him for performing a flipping loop. Ever since, the two have always flown together, with Sky unaware of Vapor helping him and Vapor not realizing that her help was actually a detriment to his flying development.
Despite this, Vapor Trail wants to see Sky Stinger realize his dream of becoming a Wonderbolt, not concerned with becoming one herself. Twilight and Rainbow Dash help her achieve this by help both her and Sky improve their flying. However, when Vapor eventually reveals to Sky that she's been supporting him and that he isn't as talented a flyer as he believes, Sky lashes out at her in anger, and the two have a falling-out.
Rainbow Dash later approaches Vapor Trail to compliment her flying, and Vapor comes to realize that being a Wonderbolt is indeed something she wants for herself. With Twilight and Rainbow's guidance, Vapor makes amends with Sky Stinger, and they assist each other in improving their flying skills. In the end, both Vapor and Sky impress the testing instructors enough to be granted entry into the Wonderbolt Academy.
Vapor Trail is featured in the "Wonderbolts Quest" section of the My Little Pony: Cutie Map Quest A Punch-Out & Play Activity Book, which was released prior to her debut in the series.
