I can’t be the only one who has noticed similarities between some of the Ponies and the Crests from Digimon, right?
 
Twilight/Knowledge - Self explanatory  
Applejack/Honesty - The crest is called Honesty in Japan, A.J.‘s element.  
Pinkie/Friendship - While Twilight maybe the Princess of Friendship, there’s no question who is the most friendliest of ponies.  
Rainbow/Courage - She’s arguably the bravest Pony in Equestria.  
Rarity/Purity - Once again, called Purity in Japan. Rarity just feels like she is the purest of the main ponies.  
Fluttershy/Kindness - Self explanatory.  
CMC/Hope - I may be stretching this, but their determination to get their cutie marks can be a sign of their hope.  
Celestia/Light - She brings the sun.  
Cadance/Love - Self explanatory.
