The Wonderbolts are such a great creation of the show… combination celebrities, athletes and military, with a little bit of super-hero styling thrown in via flight-suit design. Spitfire covers a fair amount of character ground herself, from the laid-back personality at the Gala to the drill sergeant attitude on display at the Wonderbolts Academy. It’s no surprise that she’s become a favorite recurring character in the show.
I suspect we’ll be seeing much more of her in Season 4, as Dash and Twilight have had the most drive behind their long-term continuity, and Dash’s is the one with the most need for some kind of resolution now that Twilight has already ascended to Princesshood. The question for me is, can Dash ever become a full Wonderbolt and still hang out in Ponyville most of the time, or is it a full-time gig?
