I decided to use Sylvester McCoy the Seventh Doctor for Twilight, not just because 10 was already taken, but because although they appear cute and harmless on the outside, they hold a sinister amount of power and can crush any of their enemies easily.

I decided to use Paul McGann the Eighth Doctor for Rarity mainly because they both have an aristocratic air to them, and are more romantic than the other Doctors/ponies.
