Spitfire is a yellow pegasus pony with a fiery orange mane. In Friendship is Magic, Spitfire is the Captain of the aerial acrobatics team the Wonderbolts, as well as a Drill Instructor for hopeful Wonderbolt recruits. While she is a generally mellow pony off-duty, she puts on an aggressive, no-nonsense demeanor on the job, especially when handling recruits.
