Wonderbolts Academy

S3, E7: Rainbow Dash is accepted into the Wonderbolt Academy, led by Spitfire, and quickly becomes friends with Lightning Dust, another pegasus who is as fast and skilled as her, but is more rambunctious. Rainbow Dash is surprised to find she is assigned as "wingpony" to Lightning Dust and becomes concerned when her aggressive approach endangers the other cadets. When Lightning Dust decides to create a tornado during a cloud-clearing exercise, the tornado threatens to harm Rainbow's friends, who have come by to give her a care package. Though everyone is safe in the end, Rainbow decides to quit the Wonderbolts, finding the organisation's apparent approval of such reckless behaviour morally abhorrent. However, Spitfire reveals that she agrees with her and persuades Rainbow to withdraw her resignation with a promotion to cadet team leader, stripping Lightning Dust of her rank.
