Sky Stinger is a male Pegasus pony and Wonderbolts cadet who first appears in Top Bolt.

Depiction in the series
Sky Stinger first appears in the season six episode Top Bolt as an applicant to the Wonderbolt Academy. During the classroom portion of applicant testing, he is portrayed as very self-confident and egotistical; he is certain of his ability to become a Wonderbolt, and he dismisses the need to go over basic flying techniques with instructors Twilight Sparkle and Rainbow Dash.

However, Sky later demonstrates genuine concern for his best friend and wingpony Vapor Trail, who he believes is a weaker flyer than himself and in need of improvement. During freestyle training, it is revealed that Sky Stinger is unable to perform aerial tricks without Vapor Trail's support, and this has been the case ever since the two first met when they were young. Sky Stinger is also revealed to have come from a large family where he had a difficult time getting attention.

Twilight and Rainbow Dash help Sky improve his aerobatics under the guise of helping Vapor Trail, but he still insists that he doesn't need practice and will easily make it into the Academy. When Vapor Trail reveals that she's been having supporting Sky the whole time, he is mortified. He accuses Vapor of trying to humiliate him and steal his thunder, and the two have a harshly worded falling-out.

As a result of his argument with Vapor, Sky's confidence is ruined to the point where he makes no effort to impress Spitfire. With Twilight and Rainbow Dash's guidance, Sky makes amends with Vapor Trail. He trains hard to improve his own flying skills while at the same time giving Vapor tips on how to improve hers. In the end, both Sky and Vapor impress the testing instructors enough to be granted entry into the Wonderbolt Academy.

In the season seven episode Parental Glideance, Sky Stinger makes a cameo appearance walking alongside Vapor Trail at the Wonderbolt Academy. They also briefly appear talking together at the Academy in Secrets and Pies.

In the season nine episode The Ending of the End - Part 2, Sky Stinger briefly appears taking shelter with Vapor Trail and other Pegasi in Cloudsdale as the city closes itself off from the other pony races. In The Last Problem, Sky Stinger briefly appears in Rainbow Dash's group shot during The Magic of Friendship Grows.
