Cutie Mark Crusaders

The Cutie Mark Crusaders (CMC or simply the Crusaders for short) is a club consisting of Apple Bloom, Scootaloo, and Sweetie Belle formed in Call of the Cutie, with Babs Seed joining in One Bad Apple, Imp joining in the IDW comics' My Little Pony Micro-Series Issue #7, Gabby joining in The Fault in Our Cutie Marks, and Lilymoon joining in Ponyville Mysteries: The Tail of the Timberwolf. Their unity is based on mostly being called "blank flanks", ponies who have not yet gotten their cutie marks; Imp, rather than being a blank flank pony, is a Mimicker who has not yet settled on one form, Gabby is a griffon, and Lilymoon already has her cutie mark at the time of her joining.

Each of the founding three fillies represents a different race, with Apple Bloom, Scootaloo, and Sweetie Belle being an Earth pony, a Pegasus, and a unicorn respectively. Starting at the end of One Bad Apple, Babs Seed, Apple Bloom's cousin from Manehattan, joins them and says she will start a Manehattan branch of the CMC. In My Little Pony Micro-Series Issue #7, a Greater Equestrian Mimicker (Globulus Improbulus) to whom Scootaloo gives the name "Imp" joins them[1] but is later taken back home. In Friends Forever Issue #2, the Crusaders accept Discord as an honorary member. The exploits of the Cutie Mark Crusaders are featured in several episodes in the series.

Babs receives her cutie mark off-screen in Bloom & Gloom, and Apple Bloom, Sweetie Belle, and Scootaloo receive theirs in Crusaders of the Lost Mark.
