Carmine Luster:  
Daughter of Twilight Sparkle and an unknown sire. Considered the black sheep of the family due to an inability to harness her magic. Kind but distant, she is not often in contact with her family. Takes a while to warm up to others, but is secretly very passionate and loving deep down.  
 
Rome Red Apple:  
Son of Big Mac and Cheerilee. Stubborn and loud, Rome Red can be crass and inappropriate at first glance. Despite initial thinking, he is quite self conscious about how others feel about him and often overworks himself to the point of exhaustion for the approval he feels he must make up for.
