Artist's description from DA:To my knowledge, all (but two) stallions who make an appearance in Wonderbolts Academy (Season 3, Episode 7). Besides the left two, they are in the order that they appear, from left to right/top to bottom.
I thought I should revisit the cadet uniform that I like a little too much.
I omitted the one recolored from Mercury during the weather factory scene on purpose since I assume he and the rest of the group were recolored from the main group the episode was focused on for that one instance, and were basically recolored from the ponies they thought would receive the least attention, hoping that no one would notice. The other not here is Bulk Biceps/Snowflake.
Mercury's eyes are green throughout most of the episode. I wrote some speculation on why that is here if interested.
From left to right, by row:
* Mercury (or Milky Way; recently merchandised as "Starry Eyes"), Stormfeather, Spectrum (recently merchandised as "Rainbow Swoop"), Thorn, and Crescent Moon
* Thunderlane, Starburst, Warm Front (ex-Sunburst), Brolly (merchandised as Whitewash), and Star Hunter (lolwereyougonnasayhe'sjackwelltoobadheain't)
