Higher Flier OR My Little Black Bird/YMMV


 * Fan Dumb: A few people have decided that being faster than Rainbow Dash under very limited circumstances that Dash has never even considered trying (straight lines at extreme altitudes) makes Dainty Dash an automatic Mary Sue.

 * Moe: The Central character, oh so much...
