She is the pony version of Belle with magic as a bonus. Love of books, has a high IQ, and is a beauty that describes them both.

Twilight Sparkle singing: “Madam Gaston”  
“Can you just see it?”  
“Madam Gaston”  
“His little wife?”  
“No sir! Not me!”  
“I’ll guaranteed it”  
“I want much more than this provincial life”  
“I want adventure in the great wide somewhere”  
“I want it more then I can tell”  
“And for once it might be grand”  
“To have someone understand”  
“I want so much more than they’ve got planned”
